+
+ * magick/segment.c (Classify): Remove variables from function
+ global scope that don't need outer scope.
+
+ * coders/jp2.c: JasPer changed its jas_stream_ops_t callback
+ interfaces in releases 2.0.19 and 2.0.20. Revert to providing the
+ older interfaces by default, but use a
+ MAGICK_JP2_NEW_STREAM_INTERFACE pre-processor definition to
+ support selecting the new interfaces. We don't know how to
+ usefully tell the JasPer version at compile time! Luckily, using
+ the older interfaces only causes a compiler warning rather than a

+
+ * coders/jp2.c (BlobWrite): Update Jasper stream OPs callback

+
+2020-07-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * NEWS.txt: Update with changes up to 2020-07-15.
+
+ * magick/render.c (DrawImage): Improve error handling so errors
+ are returned when they should be. Fixes oss-fuzz 24117
+ "Stack-overflow in DrawImage" and oss-fuzz 24126 "Timeout in
+ coder_MVG_fuzzer". Restore the original behavior of
+ DrawClipPath() when there is no matching clip-path attribute.
+
+2020-07-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * NEWS.txt: Update with changes up to 2020-07-12.
+
+2020-07-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/xwindow.c (MagickXVisualColormapSize): Fix UBSAN integer
+ overflow warning.
+
+ * magick/render.c (DrawClipPath): Report only a warning if there
+ is no clip mask.
+ (ExtractTokensBetweenPushPop): Verify that the expected/required
+ pop statement is indeed found. Fixes oss-fuzz 23498 "Timeout in
+ coder_MVG_fuzzer".
+
+2020-06-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/constitute.c (ReadImage): Improve error handling related
+ to ImageToFile().
+
+ * magick/image.c (SetImageInfo): Improve error handling related to
+ ImageToFile().
+
+ * coders/mat.c: Check MagickFindRawImageMinMax() return status.
+
+ * magick/constitute.c (MagickFindRawImageMinMax): Verify that the
+ original seek position was restored.
+
+2020-06-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/render.c (DrawImage): Apply stricter range limits when
+ converting a double to a long in order to avoid integer overflow.
+ Fixes oss-fuzz 23304 "Integer-overflow in DrawImage".
+ (DrawClipPath): If there is no matching clip-path attribute then
+ return an informative error. Fixes oss-fuzz 23187 "Stack-overflow
+ in DrawImage" which is actually a case of DrawImage() /
+ DrawClipPath() recursion.
+
+2020-06-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * coders/wpg.c (UnpackWPGRaster): Fix oss-fuzz 23042
+ "Heap-buffer-overflow in ImportGrayQuantumType" and oss-fuzz
+ "Heap-buffer-overflow in InsertRow" which are both from the same
+ cause.
+
+2020-06-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/pixel_cache.c (ClipCacheNexus): Change x and y variables
+ to unsigned type.
+
+2020-05-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * coders/tiff.c (WriteTIFFImage): WebP compression only supports a
+ depth of 8. Fixes oss-fuzz 22560 "Use-of-uninitialized-value in
+ GammaToLinear".
+
+2020-05-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * coders/wpg.c (ReadWPGImage): Terminate reading when a pixel
+ cache resource limit is hit rather than moving on to heap buffer
+ overflow. Fixes oss-fuzz 20045, 20318, 21956
+
+ * coders/png.c (ReadMNGImage): If the image width is 1, then X
+ magnification is done by by simple pixel replication. If the
+ image height is 1, then Y magnification is done by simple pixel
+ replication. Fixes oss-fuzz issue 19025 "Heap-buffer-overflow in
+ ReadMNGImage" and oss-fuzz issue 19026 "ASSERT: yy < (long)
+ large_image->rows". It appears that CERT has assigned
+ CVE-2020-12672 for oss-fuzz issue 19025. Note that the heap
+ overwrite is only one byte.
+
+2020-05-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * NEWS.txt: Update with changes up to 2020-04-23.
+
+2020-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * coders/dpx.c (ReadDPXImage): Support dpx:swap-samples-read
+ define which behaves similar to dpx:swap-samples, but is only
+ applied when reading. This provides for use when there is both
+ reading and writing in the same operation.
+ (WriteDPXImage): Support dpx:swap-samples-write define which
+ behaves similar to dpx:swap-samples, but is only applied when
+ writing. This provides for use when there is both reading and
+ writing in the same operation.
+
+2020-04-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick: Fix remaining GCC 10 warnings.
+
+2020-04-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/transform.c (GetImageMosaicDimensions): Mark function as pure.
+
+ * magick/effect.c (GetNonpeakMedianList): Mark function as pure.
+
+ * coders/fits.c (InsertRowHDU): Fix scary-sounding GCC 10 warning,
+ which is actually benign.

+ * config/config.sub: Update to latest config.sub
+
+ * config/config.guess: Update to latest config.guess.
+
+ * Makefile.am: Update to Automake 1.16.2
+
+2020-04-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * coders/dpx.c (ReadRowSamples): Simplify 10-bit packed decoding.
+ (WriteRowSamples): Simplify 10-bit packed encoding.
+
+ * coders/locale.c (ReadConfigureFile): Ignore comment element if
+ it was not found or is too short.
+
+ * magick/pixel_cache.c (ReadCacheIndexes): If SetNexus() has
+ previously failed to allocate the staging buffer and thus reported
+ an exception to the user, then ReadCacheIndexes() should report an
+ error rather than blundering into copying indexes data to a null
+ pointer.
+
+ * magick/effect.c (AdaptiveThresholdImage): Assure that we don't
+ attempt to write to output pixels if they have not been selected
+ yet.
+
+ * magick/utility.c (ExpandFilenames): Properly handle NULL
+ filelist and NULL filelist entries.
+ (GetGeometry): Assure that there is no one-character stack read
+ overflow when reading the geometry buffer.
+
+2020-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * fuzzing/oss-fuzz-build.sh: Restore xz to oss-fuzz build due to
+ build problems getting worked out.
+
+2020-03-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * fuzzing/oss-fuzz-build.sh (MAGICK_LIBS): Remove mention of
+ liblzma.a in the oss-fuzz build until its build problems get
+ worked out.
+
+2020-03-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * fuzzing/oss-fuzz-build.sh: Skip building xz in the oss-fuzz
+ build until its build problems get worked out.
+
+2020-03-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/log.c (InitializeLogInfoPost): Don't load log.mgk if
+ logging is already configured to use MethodOutput.
+
+2020-03-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/log.c (InitializeLogInfoPost): Mark that logging is
+ configured, regardless of if "log.mgk" was discovered.
+
+2020-03-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * VisualMagick/magick/magick_config.h.in: ProvideDllMain is now
+ disabled by default since it causes InitializeMagick() to be
+ invoked prior to when the program's main() routine is called,
+ thereby blocking configuration activities or use of
+ InitializeMagickEx(). With this change it is even more imperative
+ that InitializeMagick() be explicitly invoked by all programs
+ using GraphicsMagick.
+
+ * magick/log.c (LogMagickEventList): Always use/respect the
+ configured log format as might be obtained from "log.mgk" or
+ SetLogDefaultFormat().
+
+ * magick/utility.c (MagickFormatString): Return the size of the
+ formatted string.
+ (MagickFormatStringList): Return the size of the formatted string.
+ (FormatString): Return the size of the formatted string.
+ (FormatStringList): Return the size of the formatted string.
+
+2020-03-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * www/api/types.rst: Improved types documentation and added more
+ hyperlinks.
+
+ * scripts/format_c_api_doc.py: Add hyperlinks for 'LogMethod' and
+ 'LogOutputType' type documentation.
+
+ * Magick++/lib/Image.cpp (SetLogDefaultEventType): New C++ function to
+ forward to C interface.
+ (SetLogDefaultGenerations): New C++ function to forward to C
+ interface.
+ (SetLogDefaultLimit): New C++ function to forward to C interface.
+ (SetLogDefaultFormat(): New C++ function to forward to C
+ interface.
+ (SetLogDefaultLogMethod): New C++ function to forward to C
+ interface.
+ (SetLogDefaultFileName): New C++ function to forward to C
+ interface.
+ (SetLogDefaultOutputType): New C++ function to forward to C
+ interface.
+
+ * magick/log.c (SetLogDefaultEventType): New function to support
+ setting the default set of events which will result in a log
+ event.
+ (SetLogDefaultGenerations): New function to specify the maximum
+ number of log files maintain before circulating back to overwrite
+ the first name.
+ (SetLogDefaultLimit): New function to specify the maximum number
+ of logging events which may occur before creating a new log file.
+ (SetLogDefaultLogMethod): New function to provide a call-back
+ function to be invoked for each log event when the logging method
+ type is MethodOutput.
+ (SetLogDefaultOutputType): New function to set the logging output
+ destination.
+ (SetLogDefaultFormat): New function to provide the format of the
+ logging output.
+ (SetLogDefaultFileName): New function to provide the file name,
+ or file path, to be written to for each log event.
+ (InitializeLogInfo): If a default logging callback was provided
+ via SetLogDefaultLogMethod() then skip searching for "log.mgk".
+ In this case it is assumed that the API user has already changed
+ any other logging default which would have been updated by
+ "log.mgk" so it would be harmful to search for it, or read from
+ it.
+
+2020-03-10 Troy Patteson <troyp@ieee.org>
+
+ * coders/png.c (WriteOnePNGImage): Don't skip optional Exif
+ identifier code if it isn't present.
+
+2020-03-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/pixel_cache.c (ModifyCache): Destroy clone_image.cache if
+ ClonePixelCache() reports failure. Fixes oss-fuzz 20871
+ "graphicsmagick:coder_MVG_fuzzer: Direct-leak in
+ MagickMallocAligned".
+
+ * magick/log.c (LogMagickEventList): Prepare source module base
+ name more efficiently. Move MethodOutput implementation to the
+ front so it is not filtered by other active blocks.
+ (LogMagickEventList): Cache broken-down time structure in LogInfo
+ and recompute only when needed.
+
+2020-03-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/resize.c (HorizontalFilter): Improve tracing.
+ (VerticalFilter): Improve tracing.
+ (ResizeImage): Improve tracing.
+
+ * www/api/api.rst: Add functions from log.c and render.c.
+
+ * magick/log.c (DestroyLogInfo): DestroyLogInfo is no longer
+ marked MagickExport.
+
+2020-03-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ * magick/api.h: Add "magick/enum_strings.h" to API headers.
+ Requested by Przemysław Sobala via posting to the
+ graphicsmagick-help mailing list on 2020-02-27.
+
+ * scripts/html_fragments.py: Automatically generate HTML footer
+ content and include commented HTML fragment which may be
+ substituted with SF tracker for SourceForge web site.
+
2020-02-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

:local:
+1.3.36 (December 26, 2020)
+==========================
+
+Special Issues:
+
+* None
+
+Security Fixes:
+
+* GraphicsMagick is participating in Google's oss-fuzz project due to
+ the contributions and assistance of Alex Gaynor. Since February 4
+ 2018, 454 issues have been opened by oss-fuzz (some of which were
+ benign build issues such as SourceForge Mercurial not working
+ correctly) and 7 issues remain open (all of which are marked in an
+ "unreproducible" state). The issues list is available at
+ https://bugs.chromium.org/p/oss-fuzz/issues/list under search term
+ "graphicsmagick". Issues are available for anyone to view and
+ duplicate if they have been in "Verified" status for 30 days, or if
+ they have been in "New" status for 90 days. Please consult the
+ GraphicsMagick ChangeLog file, Mercurial repository commit log, and
+ the oss-fuzz issues list for details.
+
+* WPG: Fixes for heap buffer overflow.
+
+Bug fixes:
+
+* ConstituteImage(): Set image depth appropriately based on the
+ storage size specified by StorageType and QuantumDepth.
+
+* GetImageBoundingBox(): Fix problem that MagickTrimImage with extreme
+ fuzz values could produce an image with negative width.
+
+* ImageToFile(): Improve error handling to avoid possible deferred
+ deletion of temporary files, causing unexpected excessive use of
+ temporary file space.
+
+* JNG: Add validations for alpha compression method values and use
+ this information to enforce decoding using the appropriate
+ sub-format (rather than auto-detecting the format). Also, address
+ memory leaks which may occur if the sub-decoder does something other
+ than was expected.
+
+* MagickCondSignal(): Improvements to conditional signal handler
+ registration (which avoids over-riding signal handlers previously
+ registered by an API user).
+
+* ModifyCache(): Fix memory leak.
+
+* ReadCacheIndexes(): Don't blunder into accessing a null pointer if
+ the using code has ignored a previous error report bubled-up from
+ SetNexus().
+
+* MNG: When doing image scaling and the image width or height is 1
+ then always use simple pixel replication as per the MNG
+ specification.
+
+* MVG: Fixes to 'push clip-path foo' and 'pop clip-path foo' parsing
+ to eliminate a class of malign behavior.
+
+* MVG: Place an aribrary limit on stroke dash polygon unit maximum
+ length in order to avoid possibly rendering "forever".
+
+* PCL: No longer attempt to handle reading HP PCL format via the
+ external 'hp2xx' program since it seems worthless for that task.
+
+* PS: Fix corrupt image when writing PseudoClass image with a colormap
+ larger than two entries as bilevel.
+
+* SVG: Memory leak fixes.
+
+* SVG reader: Now support 'ping' support so the identify command works
+ as expected.
+
+* TIFF: WEBP compression only supports a depth of 8 so force that
+ value.
+
+* Wand MagickSetSamplingFactors(): Correct formatting of sampling
+ factors string.
+
+New Features:
+
+* Logging is now fully programmable.
+
+* DPX format: Support dpx:swap-samples-read define which behaves
+ similar to dpx:swap-samples, but is only applied when reading, as
+ well as dpx:swap-samples-write, which is only applied when
+ writing. This provides for use when there is both reading and
+ writing in the same operation (otherwise the final result was no
+ effect!).
+
+API Updates:
+
+* magick/api.h: Add "magick/enum_strings.h" to API headers.
+
+* New log settings accessor C functions: SetLogDefaultFileName(),
+ SetLogDefaultFormat(), SetLogDefaultOutputType(),
+ SetLogDefaultLogMethod(), SetLogDefaultLimit(),
+ SetLogDefaultGenerations(), SetLogDefaultEventType(). These
+ functions allow a program to set the same parameters which may be
+ set by loading a "log.mgk" function. If a default logging callback
+ was provided via SetLogDefaultLogMethod() such that MethodOutput is
+ used, then the search for a "log.mgk" is avoided entirely.
+
+* New log settings accessor C++ functions: SetLogDefaultFileName(),
+ SetLogDefaultFormat(), SetLogDefaultOutputType(),
+ SetLogDefaultLogMethod(), SetLogDefaultLimit(),
+ SetLogDefaultGenerations(), SetLogDefaultEventType(). These C++
+ functions just pass through to the equivalent C functions and
+ provide the same benefits.
+
+Feature improvements:
+
+* A simple resource-limit respecting memory allocator has been
+ developed for internal use wherever arbitrarily-large amounts of
+ memory might be requested. This will gradually be added wherever it
+ appears to be needed. The memory resource limits are at the overall
+ process level. The MVG/SVG rendering code is updated to use this
+ new allocator. Almost all of the coders (image format
+ readers/writers) have now been updated to use this new allocator.
+ This means that '-limit memory 300MB' would be more complete and
+ meaningful now. Temporary allocations by the image processing
+ algorithms (other than for the images themselves) are still not
+ accounted for in the resource limiting.
+
+* MVG Renderer / DrawImage(): Use resource-limit respecting memory
+ allocators for remaining large memory allocations.
+
+* PNG writer: Don't skip optional Exif identifier code if it isn't present.
+
+* DPX reader/writer: decode/encode of 10-bit packed DPX is now twice
+ as fast due to code simplification.
+
+* TIFF reader: Apply the same resource limits to TIFF tile sizes as
+ apply to the image itself.
+
+Windows Delegate Updates/Additions:
+
+* None
+
+Build Changes:
+
+* configure.ac: Update syntax to avoid using deprecated syntax
+ according to Autoconf 2.69. Also added copious m4 quoting.
+
+* Magick++ Drawable base class no longer uses std::unary_function when
+ compiled using C++'17 or later, since this feature has been removed
+ from the language.
+
+* Support the configure option --disable-compressed-files to disable
+ automatic decompress of gzip and bzip2 compressed files (e.g. files
+ with extension 'gz' or 'bz2', and sometimes 'svgz', but sometimes
+ posing as some other format). It turns out that there are some
+ extremely compressed files (e.g. over 1000x compression ratio) which
+ can take a long time to decompress and produce large temporary
+ files. We currently normally wait for the whole file to be
+ decompressed before decoding it. The only exception is for coders
+ with native 'blob' support and which do not require seeking, and
+ that the user forced forced the format by adding a magick prefix
+ like "DPX:file.dpx" to avoid the automatic file format detection.
+
+* Support the configure option --without-gs to disable reading PS,
+ EPS, and PDF formats via an external Ghostscript delegate program.
+ This corresponds to the HasGS definition in the source code.
+
+* Support the configure option --without-gdi32 to support disabling
+ use of the Microsoft Windows gdi32 library if it is not wanted.
+
+* The Automake-based test suite now applies a memory limit of 128MB
+ for the Q8, or 256MB for the Q16, or 512MB for the Q32 build, as
+ well as setting a disk space limit of 0. The limits place an upper
+ bound on the resources required, while assuring that tests do pass
+ with resource limits applied, while also assuring that disk-based
+ pixel-cache files are not used.
+
+Behavior Changes:
+
+* Previously the formatting settings from "log.mgk" were only used
+ when writing to a file, or to the console, via a file handle. Now
+ the log formatting has been normalized so that the settings provided
+ by "log.mgk" (or SetLogDefaultFormat()) will always be used. It is
+ possible this may result in some formatting changes.
+
+* In the Windows Visual Studio build, the ProvideDllMain option is now
+ disabled by default (can still be enabled) since it causes
+ InitializeMagick() to be invoked prior to when the program's main()
+ routine is called, thereby blocking configuration activities or use
+ of InitializeMagickEx(). With this change it is even more
+ imperative that InitializeMagick() be explicitly invoked by all
+ programs using GraphicsMagick.
+
1.3.35 (February 23, 2020)

+the localeC.XML file. Macros were added to error.h to allow the
+code to be compiled for either string based access or binary ID
+based access. Using binary ID's will cause the code to fail to
+compile if a message does not exist in C.XML, since no ID will be
+created for a missing message. This change then allowed us to
+easily track down all the messages that were "missing" or not
+being accessed properly. The problems were massive and took many
+days to resolve. I have left the code compiling in ID mode to keep
+things in sync going forward and also because it makes message
+lookup instantaneous. An ID is just an index into and array of
+char *'s. There is still a lot of cleanup work remaining, but this
+is a very good start.</li>

+gm.rc: Changes to get things compiling again since all windows
+specific logging support has been eliminated. The special build
+script BuildImageMagickObject.cmd now compiles the message file
+for resource based messages. The result is in gm_messages.bin.
+The script also generates a special version of gm.exe that uses

+<li>magick/error.c, magick/error.h, magick/log.c, magick/log.h:
+Upgrade of logging system to take over previous special logging
+code for windows in nt_base.c. The new logic provides logging of
+events to the debug api and the windows event log and also
+provides a generic text file logging method.</li>
+<li>magick/gm_messages.bin, magick/ImageMagick.rc: New compiled
+message file based on data in localeC.mgk. RC file modified to
+include this as a resource.</li>
+<li>magick/locale.c, magick/locale_c.h: locale_c.h is generated by
+the LOCALEH format of the locale coder. The logic in locale.c uses
+the tables in the header lookup messages. On windows, all the

+Patteson with description (related to provided Coverity reports in
+coverity.txt): Those coverity errors indicate a problem with the
+earlier patch I sent you to fix getting the EXIF orientation when
+the GPS IFD occurs before the EXIF IFD. Although the patch fixed
+that issue it introduced a new issue in that GPS tags could no
+longer be retrieved. This occurs because the gpsfound flag is set
+when the GPS IFD is pushed onto the stack but then cleared
+immediately when breaking out of the loop processing the directory
+entries for the current IFD. The solution is to push the gpsfound
+flag onto the stack as well as it needs to be set when the GPS IFD
+is popped off the stack rather than being set straight away.</p>
+<p>The second coverity error relates to gpsoffset not being set in
+FindEXIFAttribute(). The code that sets gpsoffset in
+GenerateEXIFAttribute() was embedded in the code that gets tags

+<li><p class="first">magick/attribute.c: From SourceForge patches #47
+"GraphicsMagick-1.3.25-5-set-exif-orientation.patch" by Troy
+Patteson with description: Rotating an image without resetting the
+EXIF orientation tag is problematic as follow-on viewers that
+support the EXIF orientation tag may incorrectly rotate the image
+a second time. For JPEG images, the current solution is to either
+strip the image, remove the EXIF profile or modify the EXIF data
+of the written image with other software. This patch adds the
+ability to set the orientation tag in the EXIF profile via the
+SetImageAttribute on attribute EXIF:Orientation provided the EXIF
+orientation already exists. AutoOrientImage() has been modified to
+set the EXIF orientation tag on successful rotation of the image.</p>
+<p>The implementation is less than ideal. The EXIF profile must be
+duplicated because it is returned read-only from the profiles
+map. Large amounts of the GenerateEXIFAttribute() function has
+been duplicated in a function called FindEXIFAttribute() which
+returns the offset in the EXIF profile of a given tag ID. Once
+found, the orientation tag value is updated accordingly and the
+new EXIF profile set. Despite the patches shortcomings, I believe
+it is preferable to leaving the EXIF orientation tag unchanged
+after auto-orienting the image.</p>

+<li><p class="first">wand/magick_wand.c (MagickClearException): From SourceForge
+patches #47 "GraphicsMagick-1.3.25-1-wand-clear-exception.patch"
+by Troy Patteson with description: This patch adds the ability to
+clear the last Wand exception. This is particularly useful to
+clear any exception on the Wand before calling MagickReadImage()
+which can return success with a warning exception such as "JPEG
+data: premature end of data segment".
+(MagickRemoveImageOption): From SourceForge patches #47
+"GraphicsMagick-1.3.25-2-wand-remove-image-option.patch" by Troy
+Patteson with description: There is MagickSetImageOption() to set
+options like JPEG preserve-settings but no way to remove the
+option once set. Since the mechanism to remove image options
+already exists in lower-level API there seems no reason not to
+expose it in the Wand API.
+(MagickGetImageOrientation, MagickSetImageOrientation): From
+SourceForge patches #47
+"GraphicsMagick-1.3.25-3-wand-get-set-orientation.patch" by Troy
+Patteson with description: MagickGetImageOrientation returns the
+internal orientation setting which is useful to know to determine
+whether an image needs rotation. The function to set the
+orientation is less useful as it only sets the internal
+orientation setting which is only used when writing out TIFF
+files. A future patch addresses this issue.
+(MagickAutoOrientImage): From SourceForge patches #47
+"GraphicsMagick-1.3.25-4-wand-auto-orient.patch" by Troy Patteson
+with description: This patch adds auto-orient image to the Wand
+API.</p>

+resolves SourceForge issue #381 "Artifacts when scaling a PNG with
+semi-transparent pixels".</p>
+<p>ScaleImage() suffers from two problems related to the blending of
+fully transparent pixels with non-fully transparent pixels during
+the scaling operation.</p>
+<p>The first is that the colour values for fully transparent pixels
+are contributing to the colour values of the blended pixels when
+they should not.</p>
+<p>The second is that the colour values of pixels blended with fully
+and non-fully transparent pixels are scaled as though the fully
+transparent pixels contribute to the blended pixels' colour values
+when they should not. For example, if blending 10% of a fully
+opaque white pixel with 90% of a fully transparent black pixel one
+would expect the blended pixel RGBA values to be 255,255,255,25.5
+assuming 8 bit colour but they are in fact 25.5,25.5,25.5,25.5.</p>
+<p>The provided patch solves the first issue by treating the colour
+values of fully transparent pixels as zero and the second issue by
+recording the volume of each blended pixel made up of pxiels that
+are not fully transparent (0.1 in the above example) and then
+scaling the blended pixel RGB values by dividing by that
+amount. In the above example, 25.5/0.1 = 255.</p>

+<ul class="simple">
+<li>magick/render.h, (PrimitiveInfo), magick/render.c: Added
+member "flags" to PrimitiveInfo to support indicating closed
+shapes (e.g., rectangle, circle, path closed using 'z' or 'Z').
+Updated code in render.c (functions TraceXXX) to indicate
+closed shapes. This replaces the previous policy of detecing
+closed shapes by comparing the first and last points to see if
+they are identical (within MagickEpsilon). The old policy
+prevented open subpaths with the same first and last point from
+being rendered properly (per the SVG spec) when round or square
+endcaps were enabled. Part of the fix for ticket #322.</li>
+<li>magick/render.c (ConvertPrimitiveToPath): Modified duplicate
+point elimination code so that the first and last points of
+a subpath are always preserved. Consequences: (1) Allows
+for the correct rendering of the sequence "move x1 y1 line
+x1 y1" with round or square endcaps. Part of the fix for
+ticket #322. (2) Fixes a bug in which eliminating the last
+point as a duplicate caused a closed shape to no longer be
+closed. This would manifest itself, for example, as a small
+"nub" on the boundary of a filled circle.</li>
+<li>magick/render.c (GetPixelOpacity): Fixed a bug in the
+code that computed the distance between a point and a
+segment (polygon edge). Prior to this fix, for zero length
+segments this code would generate a divide-by-zero and
+incorrect output. Part of the fix for ticket #322.</li>
+<li>magick/render.c (DrawPolygonPrimitive): Polygons/paths with
+zero or one points are no longer rendered per the SVG spec.</li>
+<li>magick/render.c (DrawStrokePolygon): Per the SVG spec, a
+polygon consisting of a single move-to command is not stroked.</li>
+<li>magick/render.c (TracePath): Per the SVG spec, if the
+endpoints (x1, y1) and (x2, y2) of an arc subpath are identical,
+then this is equivalent to omitting the elliptical arc segment
+entirely. For rendering purposes the zero length arc is
+treated like a zero length "line to" command to the current
+point.</li>
+<li>magick/render.c (TraceStrokePolygon): Added code to detect
+zero length open subpaths and return a stroked polygon containing
+no points when round or square endcaps are not enabled. This
+satisfies the SVG spec requirement that zero length subpaths are
+only stroked if the 'stroke-linecap' property has a value of
+round or square.</li>
+<li>magick/render.c (TracePath): Fixed a bug in which if a "move to"
+command was followed by additional pairs of points, indicating
+implied "line to" commands, each point was added twice.</li>

+ SetLogDefaultFormat().
+
+ - magick/utility.c (MagickFormatString): Return the size of the
+ formatted string.
+ (MagickFormatStringList): Return the size of the formatted string.
+ (FormatString): Return the size of the formatted string.
+ (FormatStringList): Return the size of the formatted string.
+
+2020-03-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
+
+ - www/api/types.rst: Improved types documentation and added more
+ hyperlinks.
+
+ - scripts/format\_c\_api\_doc.py: Add hyperlinks for 'LogMethod' and
+ 'LogOutputType' type documentation.
+
+ - Magick++/lib/Image.cpp (SetLogDefaultEventType): New C++ function to
+ forward to C interface.
+ (SetLogDefaultGenerations): New C++ function to forward to C
+ interface.
+ (SetLogDefaultLimit): New C++ function to forward to C interface.
+ (SetLogDefaultFormat(): New C++ function to forward to C
+ interface.
+ (SetLogDefaultLogMethod): New C++ function to forward to C
+ interface.
+ (SetLogDefaultFileName): New C++ function to forward to C
+ interface.
+ (SetLogDefaultOutputType): New C++ function to forward to C
+ interface.
+
+ - magick/log.c (SetLogDefaultEventType): New function to support
+ setting the default set of events which will result in a log
+ event.
+ (SetLogDefaultGenerations): New function to specify the maximum
+ number of log files maintain before circulating back to overwrite
+ the first name.
+ (SetLogDefaultLimit): New function to specify the maximum number
+ of logging events which may occur before creating a new log file.
+ (SetLogDefaultLogMethod): New function to provide a call-back
+ function to be invoked for each log event when the logging method
+ type is MethodOutput.
+ (SetLogDefaultOutputType): New function to set the logging output
+ destination.
+ (SetLogDefaultFormat): New function to provide the format of the
+ logging output.

+ or file path, to be written to for each log event.
+ (InitializeLogInfo): If a default logging callback was provided
+ via SetLogDefaultLogMethod() then skip searching for "log.mgk".
+ In this case it is assumed that the API user has already changed
+ any other logging default which would have been updated by
+ "log.mgk" so it would be harmful to search for it, or read from
+ it.
+
+2020-03-10 Troy Patteson <troyp@ieee.org>
+
+ - coders/png.c (WriteOnePNGImage): Don't skip optional Exif

+<h1><a class="toc-backref" href="#id1">How does GraphicsMagick differ from ImageMagick?</a></h1>
+<p><em>GraphicsMagick</em> is originally based on (forked from) ImageMagick
+5.5.2 in November 2002, from the version distributed by ImageMagick
+Studio LLC, which is itself forked in August 1999 from ImageMagick
+developed by E. I. du Pont de Nemours and Company starting in
+1992. Other than utilities being executed as sub-commands of the 'gm'
+command, the command-line syntax and programming APIs remain entirely
+upward compatible with ImageMagick 5.5.2. A better question might be
+"<em>How does ImageMagick differ from ImageMagick?</em>" since ImageMagick
+continues to alter and evolve its interfaces so they are no longer
+completely compatible with earlier versions. While GraphicsMagick also
+adds new features, it does so in a way which assures that existing
+features work as they did before. ImageMagick focuses on adding new
+functionality and features and has dramatically mutated several times
+since the fork.</p>
+<p>GraphicsMagick maintains a stable release branch, maintains a detailed
+ChangeLog, and maintains a stable source repository with complete version
+history so that changes are controlled, and changes between releases are
+accurately described. GraphicsMagick provides continued support for a
+release branch. ImageMagick does not offer any of these things.</p>
+<p>Since GraphicsMagick is more stable, more time has been spent optimizing
+and debugging its code.</p>
+<p>GraphicsMagick is much smaller than ImageMagick and has dramatically
+fewer dependencies on external libraries. For example, on the FreeBSD
+operating system, a fully-featured install of GraphicsMagick depends
+on 36 libraries whereas ImageMagick requires 64. GraphicsMagick's
+installation footprint is 3-5X smaller than ImageMagick.</p>
+<p>GraphicsMagick is usually faster than ImageMagick. The baseline execution
+overhead for simple commands is much lower, and GraphicsMagick is also
+more efficient at dealing with large images.</p>
+</div>
+<div class="section" id="how-often-does-graphicsmagick-pick-up-new-code-from-imagemagick">
+<h1><a class="toc-backref" href="#id2">How often does GraphicsMagick pick up new code from ImageMagick?</a></h1>
+<p>GraphicsMagick never picks up new code from ImageMagick as distributed
+by ImageMagick Studio LLC. Not long after the GraphicsMagick project
+was started in November 2002, ImageMagick from ImageMagick Studio LLC
+abandoned the MIT X11 style license it had been using since 1992, and
+switched between several different licenses until it ended up with one
+based on the Apache license, which is intended to penalize projects
+which borrow some of its source code, or fork from it. Since that
+time, GraphicsMagick has not incorporated any ImageMagick source code.</p>
+<p>On November 27, 2003 ImageMagick Studio LLC applied to register
+"ImageMagick" as its trademark, and it was awarded this registered
+trademark (serial number 78333969) on August 30, 2005. Those who
+re-distribute modified versions of "ImageMagick" (e.g. patched or
+improved) under license as "ImageMagick" now face the risk of
+arbitrary trademark infringement claims by ImageMagick Studio LLC.</p>
+<p>Authors of new features are encouraged to independently contribute
+their work to the GraphicsMagick project so that it can be released
+under GraphicsMagick's MIT X11 style license without additional
+encumberment. In order for a work to be accepted, it must have been
+developed entirely outside the ImageMagick source base to avoid any
+possibility of copyright taint.</p>

+<div class="section" id="are-there-any-plans-to-use-opencl-or-cuda-to-use-a-gpu">
+<h1><a class="toc-backref" href="#id3">Are there any plans to use OpenCL or CUDA to use a GPU?</a></h1>
+<p>It is well known that some math-intensive algorithms run very quickly
+on video-card (and stand-alone) GPUs. Video card vendors encourage
+you to buy an expensive video card with quite a lot of installed RAM
+and modify applications to use the GPU via their proprietary or
+limited-purpose APIs. GPUs are quite effective at producing images
+for real-time display, such as for video games and virtual reality.
+GraphicsMagick has been significantly updated to use multiple CPU
+cores to speed up the image processing, and work continues to thread
+the few remaining algorithms, or remove inefficiencies in algorithms
+which don't see as much speed-up as they should. Linear speedup as
+cores are added is typical for CPU-bound algorithms on well-designed
+CPUs. Regardless, <a class="reference external" href="http://en.wikipedia.org/wiki/Amdal%27s_law">Amdahl's law</a> is a significant factor
+in GraphicsMagick, with non-parallelizable code paths often dominating
+the time.</p>
+<p>It is my belief that stand-alone GPUs are a poor design (expensive,
+inefficient, failure-prone, bandwidth bottlenecked, lack
+functionality, are insecure, and are not supported in servers) and
+that multi-core CPUs will ultimately prevail. Functionality which
+currently works best in a GPU will simply be integrated into
+tomorrow's multi-core CPUs and C compilers will naturally support that
+functionality. Once GPU capabilities are integrated into CPUs, there
+will be no more need to develop specialized code for a GPU. Today 16

+<p>Use 'gm mogrify'. The 'mogrify' subcommand is designed to operate on
+any number of files in one command. Normally 'mogrify' overwrites the
+input files but the <cite>-output-directory</cite> option (which must appear
+before any input file names!) allows sending the modified files to a
+different directory (which could be in a subdirectory). For example:</p>
+<pre class="literal-block">
+gm mogrify -output-directory .thumbs -resize 320x200 *.jpg
+</pre>
+<p>If you encounter command line length limitations then you can have
+GraphicsMagick expand the file list by quoting the wildcard argument
+to prevent it from being expanded by your command shell:</p>
+<pre class="literal-block">
+gm mogrify -output-directory .thumbs -resize 320x200 "*.jpg"
+</pre>
+<p>and you can also retrieve a list of files to process from a text file
+(e.g. named 'files.txt') like:</p>
+<pre class="literal-block">
+gm mogrify -output-directory .thumbs -resize 320x200 @files.txt
+</pre>
+<p>where files.txt has one line per file name. If the input file paths
+contain relative sub-directory paths (e.g. "foo/file1", "bar/file2"),
+you can instruct GraphicsMagick to create a similar subdirectory
+structure under the output directory by adding the
+<cite>-create-directories</cite> option:</p>
+<pre class="literal-block">
+gm mogrify -output-directory .thumbs -create-directories -resize 320x200 @files.txt
+</pre>
+<p>Note that the algorithm used to generate output file names is quite
+simple. If -output-directory is "/foo" and the file path is
+"bar/none.jpg" then the final path will be "foo/bar/none.jpg". Based
+on this it should be clear that when <cite>-output-directory</cite> is used, file
+paths should be relative paths rather than absolute paths or else the
+concatenation won't work.</p>

+<div class="section" id="i-get-a-memory-allocation-error-what-can-i-do">
+<h1><a class="toc-backref" href="#id12">I get a memory allocation error. What can I do?</a></h1>
+<p>Memory allocation is a complex topic in GraphicsMagick and image
+processing requires a lot of memory. GraphicsMagick tries to take best
+advantage of the resources available by optimizing its use of <em>virtual</em>
+memory. Virtual memory is normally the amount of RAM (Random Access
+Memory) available to the process plus the amount of free space in the
+system paging area (known as "swap" under Unix, or a "page file" under
+Windows). In addition to the RAM and the paging area, GraphicsMagick is
+able to expand the amount of virtual memory available by using
+memory-mapped files which cause the file to be treated as extra memory. A
+piece of hardware known as the Memory Management Unit (MMU) performs the
+magic which allows the system paging area and memory-mapped files to be
+treated as more memory by your system's CPU.</p>
+<p>Usually when a memory allocation error occurs, it is because the system's
+paging area is full, or the programs memory (heap) is fragmented badly
+enough that there is no large-enough block of memory available to satisfy
+the request. In some cases the operating system may artificially limit
+the memory available to the program. Failures of small memory allocations
+are generally considered fatal by GraphicsMagick. If it is impossible to
+allocate even a little bit of memory, then there is no point in
+continuing. When large memory allocations associated with allocating
+memory for image pixels fail, GraphicsMagick uses that as a key to know
+that it should start using memory-mapped temporary files to increase
+virtual memory. Under Unix and other POSIX-compliant systems, these
+memory-mapped temporary files are created in either the system default
+location (e.g. <cite>/var/tmp</cite>) or the directory set by the TMPDIR environment
+variable. Under Windows, temporary files are created in the directory set
+by the TEMP or TMP environment variable. Use the MAGICK_TMPDIR
+environment variable to specify a directory for GraphicsMagick to write
+its temporary files.</p>
+<p>If the temporary file directory is too small, or is itself mapped to the
+system's paging area (no win!), then GraphicsMagick will fail to allocate
+more virtual memory via the temporary file and will return an error.</p>
+<p>The single biggest factor in how much memory is required by
+GraphicsMagick is the QuantumDepth setting when it was compiled. The
+amount of memory (in bytes) required to store a single image in memory is
+may be calculated via the equation (QuantumDepth*Rows*Columns*5)/8. As a
+means of example, the following table shows the amount of memory consumed
+by a single 1024x768 image using the supported QuantumDepth settings:</p>
+<blockquote>
+<table border="1" class="docutils">
+<colgroup>
+<col width="46%" />
+<col width="54%" />
+</colgroup>
+<thead valign="bottom">
+<tr><th class="head">QuantumDepth</th>
+<th class="head">Virtual Memory</th>

+<tr><td>16</td>
+<td>8MB</td>
+</tr>
+<tr><td>32</td>
+<td>15MB</td>
+</tr>
+</tbody>
+</table>
+</blockquote>
+<p>Performing an image processing operation may require that several images
+be in memory at one time. In the case of animations, hundreds of images
+may be in memory at one time.</p>
+<p><em>GraphicsMagick</em> is designed to be general purpose. It can display many
+image storage formats (<em>Monochrome</em>, <em>PseudoColor</em>, or <em>TrueColor</em>) on
+many different types of X visuals (<em>StaticGray, StaticColor, PseudoColor,
+GrayScale, DirectColor,</em> or <em>TrueColor</em>). To support all these
+combinations of image storage formats and X visuals, extra memory is
+required. Additionally, <a class="reference external" href="animate.html">animate</a> and <a class="reference external" href="montage.html">montage</a> store an entire image
+sequence in memory.</p>
+<p>It is recommended that systems used to run <em>GraphicsMagick</em> have at least
+96MB of RAM and 140MB free in their paging area. Systems used to process
+large images (do the math!) may require considerably more memory to
+operate efficiently. GraphicsMagick is proven to be far more efficient at
+processing huge images when it is compiled as a 64-bit application on a
+64-bit capable CPU. RAM is typically 1000 times faster than disk, so it
+is important to keep as much data in RAM as possible (buy lots of RAM).
+The temporary file area should have plenty of free space. The size of the
+temporary file area is usually the deciding factor as to whether
+GraphicsMagick is able to complete an operation. With sufficient free
+disk space, GraphicsMagick is primarily limited by your CPU, your
+operating system's ability to address memory, and your degree of
+patience. GraphicsMagick has been used to process RGB images 64K by 64K
+pixels in size!</p>

+<p>GraphicsMagick 1.2.2 and later support combining multiple channels in of

+starting with a CMYK JPEG file, we can create a set of separate files
+with one file per channel:</p>
+<pre class="literal-block">
+gm convert cmyk.jpg -channel cyan cyan.tiff
+gm convert cmyk.jpg -channel magenta magenta.tiff
+gm convert cmyk.jpg -channel yellow yellow.tiff
+gm convert cmyk.jpg -channel black black.tiff
+</pre>
+<p>and then we can join them back together:</p>
+<pre class="literal-block">
+gm composite -compose CopyMagenta magenta.tiff cyan.tiff result.tiff
+gm composite -compose CopyYellow yellow.tiff result.tiff result.tiff
+gm composite -compose CopyBlack black.tiff result.tiff result.tiff
+</pre>
+<p>Perhaps it is possible to accomplish this in one composite command. We
+will leave that as an exercise for later. Note that it is possible to
+extract just one channel, manipulate it, and then insert it back into the
+original image file.</p>
+<p>There is also built-in support for a <em>Partition</em> interlace format which
+can split to a set of files, and join a set of files, but the only
+supported format is a raw format which is not easy to deal with.</p>

+<h1><a class="toc-backref" href="#id34">What does <cite>identify</cite> report?</a></h1>
+<p>GraphicsMagick is sophisticated image handling software supporting
+perhaps a hundred formats, and hundreds of subformats, yet it needs to
+be able to apply image processing algorithms in a consistent way, and
+save to many output formats. Some image types are radically different
+from others. Due to this, GraphicsMagick normalizes images it reads
+into only nine internal in-memory formats (see the description of
+-type) which are a specialization of just two internal formats. The
+<cite>identify</cite> command reports the characteristics of one of those
+internal formats rather than the genuine properties of the input image
+file. In fact, if the properties of all the input files were to be
+reported, it would require a book to describe all of the properties.
+For example, the WMF vector-drawing format is much different from the
+PNG image file format, yet GraphicsMagick can read both.</p>
+<p>Only limited original properties are preserved, and it depends on how
+GraphicsMagick was built. For example, a "Q8" build can only report
+up to a depth of 8 bits, but a "Q32" build can report a depth of up to
+32 bits. The original image depth is reported if it is at least 8
+bits, and equal to or less than the build depth.</p>
+<p>By default <cite>identify</cite> reports only the most basic properties:</p>
+<pre class="literal-block">
+% gm identify seaworld.jpg
+seaworld.jpg JPEG 1530x1020+0+0 DirectClass 8-bit 204.0K 0.000u 0:01

+<p><a class="reference external" href="https://www.mercurial-scm.org/">Mercurial</a> (also known as <cite>Hg</cite> due to the abbreviation for Mercury in
+the periodic table of the elements) is a modern source control system
+which provides anyone who clones a repository with a stand-alone local
+repository containing the full development history and the ability to
+select any version of the code. Since the local repository is
+fully-functional, you may use the same repository to manage your local
+changes to GraphicsMagick code and you may use the repository to share
+your changes with others.</p>
+</div>
+<div class="section" id="web-access">
+<h1><a class="toc-backref" href="#id2">Web Access</a></h1>
+<p>The <a class="reference external" href="http://hg.code.sf.net/p/graphicsmagick/code/">GraphicsMagick repository at SourceForge</a> web interface is
+available which may be used to interactively view the latest versions
+of files, or the changes to files, using your web browser.</p>

+<div class="section" id="cloning-the-mercurial-repository">
+<h1><a class="toc-backref" href="#id3">Cloning the Mercurial Repository</a></h1>
+<p>To get the tree and place it in a sub-directory of your current working
+directory, issue the command:</p>
+<pre class="literal-block">
+hg clone http://hg.code.sf.net/p/graphicsmagick/code GM
+</pre>
+</div>
+<div class="section" id="selecting-a-version-of-the-code">
+<h1><a class="toc-backref" href="#id4">Selecting a version of the code</a></h1>
+<p>By default the cloned directory is populated with files from the
+<cite>default</cite> (i.e. head) branch of the code, which is where active
+development happens.</p>
+<p>If you require a specific release of GraphicsMagick (e.g. 1.3.23), you may select it like:</p>
+<pre class="literal-block">
+hg update -r GraphicsMagick-1_3_23
+</pre>
+<p>or if you require a specific branch of GraphicsMagick (e.g. 1.3), you may use:</p>
+<pre class="literal-block">
+hg update -r GraphicsMagick-1_3
+</pre>
+<p>or you may request the files which were current on a specific date:</p>
+<pre class="literal-block">
+hg update -d 2009-01-14
+</pre>
+<p>Use:</p>
+<pre class="literal-block">

+<p>and to make them visible in your files (via a merge), execute:</p>
+<pre class="literal-block">

+<p>The best place to look for the latest version of Mercurial (<cite>Hg</cite>) is
+at the <a class="reference external" href="https://www.mercurial-scm.org/">Mercurial</a> web site. Most free operating systems (e.g. Linux,
+OpenIndiana, and *BSD) will offer a version of Mercurial as an
+installable package and it may already be installed on your system.
+We recommend use of <a class="reference external" href="https://tortoisehg.bitbucket.io/">TortoiseHg</a> on Microsoft Windows systems since it
+provides a very nice graphical interface. <a class="reference external" href="https://tortoisehg.bitbucket.io/">TortoiseHg</a> is also

+<div class="section" id="mercurial-for-graphicsmagick-developers">
+<h1><a class="toc-backref" href="#id7">Mercurial for GraphicsMagick Developers</a></h1>
+<p>Since <a class="reference external" href="https://www.mercurial-scm.org/">Mercurial</a> is a distributed revision control system, you may
+clone the GraphicsMagick repository and work for days or weeks (making
+your own local commits) before you decide to push some or all of your
+changes to the GraphicsMagick development repository. GraphicsMagick
+developers first commit changes to their own local respository, then
+they push their changes to the GraphicsMagick development repository
+at hg.graphicsmagick.org, later on (after testing and possible fixes)
+I will push the changes to the stable repository at SourceForge.
+Pushes to the stable repository at SourceForge should occur at least
+as often as source code snapshots are produced.</p>
+<p>The repository hierarchy is as follows:</p>
+<ol class="arabic simple">
+<li>Local</li>
+</ol>
+<blockquote>
+The developer makes any local changes and commits what he likes in his
+own repository. It is best to commit often and whenever all the
+files have been updated to implement a coherent change or feature
+(including the ChangeLog file!) since <a class="reference external" href="https://www.mercurial-scm.org/">Mercurial</a> stores related
+changes as a changeset along with the change message you enter.
+When you push your repository, these changesets and messages are
+preserved.</blockquote>
+<ol class="arabic simple" start="2">
+<li>Unstable</li>
+</ol>
+<blockquote>
+<p>The unstable development repository is available via ssh at
+"<a class="reference external" href="ssh://yourid@hg.GraphicsMagick.org//hg/GraphicsMagick">ssh://yourid@hg.GraphicsMagick.org//hg/GraphicsMagick</a>".</p>
+<p>Where <cite>yourid</cite> is the Unix user ID on the GraphicsMagick server.
+The <cite>yourid@</cite> part may left out if your client system uses the same
+user ID as on the GraphicsMagick server.</p>
+</blockquote>
+<ol class="arabic simple" start="3">
+<li>Stable</li>
+</ol>
+<blockquote>
+The stable repository is available via http at
+"<a class="reference external" href="http://hg.code.sf.net/p/graphicsmagick/code">http://hg.code.sf.net/p/graphicsmagick/code</a>". Any changes in the
+unstable development repository are pushed to the stable repository
+(by the developer responsible for this role) once any necessary
+adjustments have been made, documentation files have been generated,
+and the software test suite has passed on at least one machine.</blockquote>
+<p>To build your local development repository (as quickly as possible),
+you may use these steps:</p>
+<ol class="arabic">
+<li><p class="first">Clone the stable respository at SourceForge:</p>
+<pre class="literal-block">
+hg clone http://hg.code.sf.net/p/graphicsmagick/code GM
+</pre>
+</li>
+<li><p class="first">Adjust your local repository path default to use the unstable repository.</p>
+<p>Edit .hg/hgrc in your local repository so that it contains:</p>
+<pre class="literal-block">
+[paths]
+default = ssh://yourid@hg.GraphicsMagick.org//hg/GraphicsMagick
+</pre>
+<p>where <cite>yourid</cite> is the Unix user ID on the GraphicsMagick server.</p>
+</li>
+<li><p class="first">Pull any additional pending updates from the unstable repository:</p>
+<pre class="literal-block">
+hg pull -u
+</pre>
+</li>
+</ol>
+<p>Please note that when ssh access is used, Mercurial uncompresses any
+data and sends it in uncompressed form. Mercurial expects that
+compression will be enabled in ssh when needed. One way to enable ssh
+compression is to put this in your local .hgrc:</p>
+<pre class="literal-block">
+[ui]
+ssh = ssh -C
+</pre>
+<p>but ssh also provides its own way to enable compression on a
+site-by-site basis (e.g. via .ssh/config). For example an entry in
+.ssh/config will enable use of compression:</p>
+<pre class="literal-block">
+Host hg.GraphicsMagick.org
+ Compression yes
+</pre>

hg clone http://hg.code.sf.net/p/graphicsmagick/code GM
+Please note that since the introduction of an HTTP load balancer,
+SourceForge has become unreliable when cloning with the default http
+protocol. Due to this, using ssh protocol may be required. Any
+SourceForge user who has submitted a SSH private key to SourceForge
+may use Mercurial over SSH to clone the repository. The ssh clone
+syntax looks like this (replacing `YOURID` with your SourceForge user
+name):

+<p>The GraphicsMagick source code is extracted into a subdirectory

+<h1><a class="toc-backref" href="#id2">Build Configuration</a></h1>
+<p>Use 'configure' to automatically configure, build, and install
+GraphicsMagick. The configure script may be executed from the
+GraphicsMagick source directory (e.g ./configure) or from a separate
+build directory by specifying the full path to configure (e.g.
+/src/GraphicsMagick-1.3/configure). The advantage of using a separate
+build directory is that multiple GraphicsMagick builds may share the
+same GraphicsMagick source directory while allowing each build to use a
+unique set of options. Using a separate directory also makes it easier
+to keep track of any files you may have edited.</p>
+<p>If you are willing to accept configure's default options (static
+build, 8 bits/sample), and build from within the source directory,
+type:</p>
+<pre class="literal-block">
+./configure
+</pre>
+<p>and watch the configure script output to verify that it finds everything
+that you think it should. If it does not, then adjust your environment
+so that it does.</p>
+<p>By default, 'make install' will install the package's files
+in '/usr/local/bin', '/usr/local/man', etc. You can specify an
+installation prefix other than '/usr/local' by giving 'configure'
+the option '--prefix=PATH'. This is valuable in case you don't have
+privileges to install under the default paths or if you want to install
+in the system directories instead.</p>
+<p>If you are not happy with configure's choice of compiler, compilation
+flags, or libraries, you can give 'configure' initial values for
+variables by specifying them on the configure command line, e.g.:</p>
+<pre class="literal-block">
+./configure CC=c99 CFLAGS=-O2 LIBS=-lposix
+</pre>
+<p>Options which should be common to packages installed under the same
+directory heirarchy may be supplied via a 'config.site' file located
+under the installation prefix via the path ${prefix}/share/config.site
+where ${prefix} is the installation prefix. This file is used for all
+packages installed under that prefix. As an alternative, the CONFIG_SITE
+environment variable may be used to specify the path of a site
+configuration file to load. This is an example config.site file:</p>
+<pre class="literal-block">
+# Configuration values for all packages installed under this prefix
+CC=gcc
+CXX=c++
+CPPFLAGS='-I/usr/local/include'
+LDFLAGS='-L/usr/local/lib -R/usr/local/lib'
+</pre>
+<p>When the 'config.site' file is being used to supply configuration
+options, configure will issue a message similar to:</p>
+<pre class="literal-block">
+configure: loading site script /usr/local/share/config.site
+</pre>
+<p>The configure variables you should be aware of are:</p>
+<p>CC</p>
+<blockquote>
+Name of C compiler (e.g. 'cc -Xa') to use</blockquote>
+<p>CXX</p>
+<blockquote>
+Name of C++ compiler to use (e.g. 'CC')</blockquote>
+<p>CFLAGS</p>
+<blockquote>
+Compiler flags (e.g. '-g -O2') to compile C code</blockquote>
+<p>CXXFLAGS</p>
+<blockquote>
+Compiler flags (e.g. '-g -O2') to compile C++ code</blockquote>
+<p>CPPFLAGS</p>
+<blockquote>
+Include paths (-I/somedir) to look for header files</blockquote>
+<p>LDFLAGS</p>
+<blockquote>
+Library paths (-L/somedir) to look for libraries Systems that
+support the notion of a library run-path may require an additional
+argument in order to find shared libraries at run time. For
+example, the Solaris linker requires an argument of the form
+'-R/somedir', some Linux systems will work with '-rpath /somedir',
+while some other Linux systems who's gcc does not pass -rpath to
+the linker require an argument of the form '-Wl,-rpath,/somedir'.</blockquote>
+<p>LIBS</p>
+<blockquote>
+Extra libraries (-lsomelib) required to link</blockquote>
+<p>Any variable (e.g. CPPFLAGS or LDFLAGS) which requires a directory
+path must specify an absolute path rather than a relative path.</p>
+<p>The build now supports a Linux-style "silent" build (default
+disabled). To enable this, add the configure option
+--enable-silent-rules or invoke make like 'make V=0'. If the build
+has been configured for silent mode and it is necessary to see a
+verbose build, then invoke make like 'make V=1'.</p>
+<p>Configure can usually find the X include and library files
+automatically, but if it doesn't, you can use the 'configure' options
+'--x-includes=DIR' and '--x-libraries=DIR' to specify their locations.</p>
+<p>The configure script provides a number of GraphicsMagick specific
+options. When disabling an option --disable-something is equivalent
+to specifying --enable-something=no and --without-something is
+equivalent to --with-something=no. The configure options are as
+follows (execute 'configure --help' to see all options).</p>

+<p>GraphicsMagick options represent either features to be enabled, disabled,
+or packages to be included in the build. When a feature is enabled (via
+--enable-something), it enables code already present in GraphicsMagick.
+When a package is enabled (via --with-something), the configure script
+will search for it, and if is is properly installed and ready to use
+(headers and built libraries are found by compiler) it will be included
+in the build. The configure script is delivered with all features
+disabled and all packages enabled. In general, the only reason to
+disable a package is if a package exists but it is unsuitable for
+the build (perhaps an old version or not compiled with the right
+compilation flags).</p>

+they allow programs to share common code, making the individual

+(otherwise an additional PERL (PerlMagick) must be installed. This
+option is not the default because all libraries used by
+GraphicsMagick must also be dynamic libraries if GraphicsMagick
+itself is to be dynamically loaded (such as for PerlMagick).</p>
+<p>GraphicsMagick built with delegates (see MAGICK PLUG-INS below)
+can pose additional challenges. If GraphicsMagick is built using
+static libraries (the default without --enable-shared) then
+delegate libraries may be built as either static libraries or
+shared libraries. However, if GraphicsMagick is built using shared
+libraries, then all delegate libraries must also be built as
+shared libraries. Static libraries usually have the extension .a,
+while shared libraries typically have extensions like .so, .sa,
+or .dll. Code in shared libraries normally must compiled using
+a special compiler option to produce Position Independent Code
+(PIC). The only time this is not necessary is if the platform
+compiles code as PIC by default.</p>
+<p>PIC compilation flags differ from vendor to vendor (gcc's is
+-fPIC). However, you must compile all shared library source with
+the same flag (for gcc use -fPIC rather than -fpic). While static
+libraries are normally created using an archive tool like 'ar',
+shared libraries are built using special linker or compiler options
+(e.g. -shared for gcc).</p>

+loadable object which is loaded into your current PERL interpreter
+at run-time. Use of dynamically-loaded extensions is preferable over
+statically linked extensions so --enable-shared should be specified
+if possible (note that all libraries used with GraphicsMagick must

+Traditionally it has been thought that a 'static' program will be
+more performant than one built with shared libraries, and perhaps
+this may be true, but building a 'static' GraphicsMagick does not
+account for the many shared libraries it uses on a typical
+Unix/Linux system. These shared libraries may impose unexpected
+overhead. For example, it was recently noted that libxml2 is now
+often linked with the ICU (international character sets) libraries
+which are huge C++ libraries consuming almost 30MB of disk space and
+that simply linking with these libraries causes GraphicsMagick to
+start up much more slowly. By using the modules build, libxml2 (and
+therefore the huge ICU C++ libraries) are only loaded in the few
+cases (e.g. SVG format) where it is needed.</p>

+<p>Larger pixel quantums cause GraphicsMagick to run more slowly and to
+require more memory. For example, using sixteen-bit pixel quantums
+causes GraphicsMagick to run 15% to 50% slower (and take twice as
+much memory) than when it is built to support eight-bit pixel
+quantums. Regardless, the GraphicsMagick authors prefer to use
+sixteen-bit pixel quantums since they support all common image
+formats and assure that there is no loss of color precision.</p>
+<p>The amount of virtual memory consumed by an image can be computed
+by the equation (QuantumDepth*Rows*Columns*5)/8. This is an
+important consideration when resources are limited, particularly

+<p>which consist of GNU-based (GCC) compilation toolsets plus headers and

+standard Microsoft Windows DLLs so that they may be used for
+proprietary applications. MSYS provides a Unix-style console shell
+window with sufficient functionality to run the GraphicsMagick
+configure script and execute 'make', 'make check', and 'make install'.
+GraphicsMagick may be executed from the MSYS shell, but since it is a
+normal Windows application, it will work just as well from the Windows
+command line.</p>
+<p>Unlike the Cygwin build which creates programs based on a
+Unix-emulation DLL, and which uses Unix-style paths to access Windows
+files, the MinGW build creates native Windows console applications
+similar to the Visual C++ build. Run-time performance is similar to the
+Microsoft compilers.</p>
+<p>The base MinGW (or MinGW-w64) package and the MSYS package should be

+shell.</p>
+<p>Start the MSYS console and follow the Unix configure and build
+instructions. The configure and build for MinGW is the same as for
+Unix. Any additional delegate libraries (e.g. libpng) will need to be

+and installed prior to configuring GraphicsMagick. While some delegate
+libraries are easy to configure and build under MinGW, others may be

+using fails the C++ exception tests, then the solution is to either
+find a MinGW with working C++ exceptions, configure a static build
+with --disable-shared, or disable building Magick++ with
+--without-magick-plus-plus.</p>
+<p>Note that the default installation prefix is MSYS's notion of

+<h1><a class="toc-backref" href="#id8">Dealing with configuration failures</a></h1>
+<p>While configure is designed to ease installation of GraphicsMagick, it
+often discovers problems that would otherwise be encountered later
+when compiling GraphicsMagick. The configure script tests for headers
+and libraries by executing the compiler (CC) with the specified
+compilation flags (CFLAGS), pre-processor flags (CPPFLAGS), and linker
+flags (LDFLAGS). Any errors are logged to the file 'config.log'. If
+configure fails to discover a header or library please review this
+log file to determine why, however, please be aware that <em>errors
+in the config.log are normal</em> because configure works by trying
+something and seeing if it fails. An error in config.log is only a
+problem if the test should have passed on your system. After taking
+corrective action, be sure to remove the 'config.cache' file before
+running configure so that configure will re-inspect the environment
+rather than using cached values.</p>
+<p>Common causes of configure failures are:</p>
+<ol class="arabic simple">
+<li>A delegate header is not in the header include path (CPPFLAGS -I
+option).</li>
+<li>A delegate library is not in the linker search/run path (LDFLAGS
+-L/-R option).</li>
+<li>A delegate library is missing a function (old version?).\eOB</li>
+<li>The compilation environment is faulty.</li>
+</ol>
+<p>If all reasonable corrective actions have been tried and the problem
+appears to be due to a flaw in the configure script, please send a
+bug report to the configure script maintainer (currently
+<a class="reference external" href="mailto:bfriesen%40graphicsmagick.org">bfriesen<span>@</span>graphicsmagick<span>.</span>org</a>). All bug reports should contain the
+operating system type (as reported by 'uname -a') and the
+compiler/compiler-version. A copy of the configure script output
+and/or the config.log file may be valuable in order to find the

+ Normally support for being able to read and write gzip/bzip stream
+ files (files which are additionally compressed using gzip or bzip)
+ is a good thing, but for some formats it is necessary to
+ decompress an entire input file before it may be validated and

install' must be done before the test suite will work but usually
the software can be tested prior to installation.
+ The test suite requires sufficient RAM memory to run. The memory
+ requirement is 128MB for the Q8 build, or 256MB for the Q16
+ build, or 512MB for the Q32 build.

'make clean'
Remove everything in the build directory created by 'make'
compiler, the CPU type, and the library versions used. The
GraphicsMagick developers use the current release of all dependent
libraries.

+<h1><a class="toc-backref" href="#id1">Installing Using Installer Package</a></h1>
+<blockquote>
+This section provides information specific to GraphicsMagick installed
+via a "setup.exe" style installation wizard under Microsoft Windows. It
+applies only to the pre-built "binaries" package, and not to versions
+compiled from source code. If you would like to install GraphicsMagick
+from source code, then please refer to the Installing From Source Code
+section.</blockquote>
+<div class="section" id="prerequisites">
+<h2><a class="toc-backref" href="#id2">Prerequisites</a></h2>
+<blockquote>
+<p>While multiple versions of GraphicsMagick may be installed at one
+time, if your intention is to replace a prior installation of
+GraphicsMagick with a newer version, then it is wise to uninstall
+the existing GraphicsMagick (see uninstall procedure) prior to
+installing the newer version.</p>
+<p>While it is not a requirement, it is strongly recommended that the
+<a class="reference external" href="http://sourceforge.net/projects/ghostscript/">Ghostscript</a>
+package (GraphicsMagick is tested with version 9.27) be
+installed. GraphicsMagick uses Ghostscript to render Postscript and
+PDF files, as well as formats where a translator to Postscript is
+available. GraphicsMagick will use the <a class="reference external" href="http://sourceforge.net/projects/gs-fonts/">Ghostscript Fonts</a> (also known as "URW
+Fonts") to support the standard set of Adobe Postscript fonts like
+"Helvetica" and "Times Roman" if these fonts are not available as
+TrueType fonts. The Ghostscript fonts need to manually installed
+with administrator privileges in the Ghostscript installation
+directory (e.g. as <tt class="docutils literal"><span class="pre">C:\Program</span> Files\gs\fonts</tt> or <tt class="docutils literal">C:Program
+Files\gs\gs9.27\fonts</tt>).</p>
+<p>The algorithm used to find the fonts consults the Windows registry
+to learn Ghostscript installation paths, and then looks for a
+"fonts/n019003l.pfb" file in each path until it finds a match.</p>
+<p>Make sure to install a Ghostscript which is compatible with the
+GraphicsMagick you are installing. For example, if you are
+installing a 64-bit GraphicsMagick, you should install a 64-bit
+Ghostscript. The installation order of the two packages is not
+important. Both 32 and 64-bit versions of GraphicsMagick and
+Ghostscript may be installed at the same time.</p>

+<h2><a class="toc-backref" href="#id3">Retrieve Install Package</a></h2>
+<blockquote>
+<p>Retrieve the GraphicsMagick Windows binary install package from a one
+of the ftp sites listed at the <a class="reference external" href="download.html">GraphicsMagick Download Sites</a> page. The available install packages are as follows</p>
+<p>Windows Dynamic-Multithread (DLL-based) install package with utilities,
+ImageMagickObject COM object, and web pages:</p>
+<blockquote>
+<pre class="literal-block">
+GraphicsMagick-1.3-Q8-win32-dll.exe
+GraphicsMagick-1.3-Q16-win32-dll.exe
+GraphicsMagick-1.3-Q8-win64-dll.exe
+GraphicsMagick-1.3-Q16-win64-dll.exe
+</pre>
+</blockquote>
+<p>Note that the QuantumDepth=8 version (Q8) which provides industry
+standard 24/32 bit pixels consumes half the memory and about 30% less
+CPU than the QuantumDepth=16 version (Q16) which provides 48/64 bit
+pixels for high-resolution color. A Q8 version is fine for processing
+typical photos intended for viewing on a computer screen. If you are
+dealing with film, scientific, or medical images, use ICC color
+profiles, or deal with images that have limited contrast, then the Q16
+version is recommended.</p>
+<p>The <cite>win32</cite> packages are for 32-bit or 64-bit Windows, whereas the
+<cite>win64</cite> packages are only for 64-bit Windows. The 64-bit version
+allows processing larger images in memory (rather than disk files),
+provided that the system has more than 2GB of RAM installed. Memory
+access is 1000 times faster than disk access.</p>

+<h2><a class="toc-backref" href="#id19">Windows XP, Vista, 7 Visual C++ 6.0 through 19.0 Compilation</a></h2>
+<blockquote>
+<p>The Visual C++ distribution targeted at Windows 2000 through Windows
+10 does not provide any stock workspace (DSW) or project files (DSP)
+except for those included with third party libraries. Instead, there
+is a "configure" program that must run to create build
+environments to satisfy various requirements.</p>
+<p>The configure program resides in <tt class="docutils literal">VisualMagick\configure</tt> in the
+GraphicsMagick source tree. A pre-compiled configure.exe is
+provided, as well as Visual Studio project files to recompile it
+from source code if needed.</p>
+<p>Once started, the configure program provides this configuration
+dialog after proceeding past the initial notifications screen:</p>
+<img alt="Configure program screen shot" class="align-center" src="configure-target-setup.png" style="width: 498.0px; height: 473.0px;" />
+<p>In addition to (or as a replacement to) the above dialog, the
+configure.exe program supports these command-line options:</p>
+<dl class="docutils">
+<dt><cite>/Q8 /Q16 /Q32</cite></dt>
+<dd>Set quantum depth</dd>
+<dt><cite>/x64</cite></dt>
+<dd>Add x64 configuration</dd>
+<dt><cite>/mtd /sts /mts /mtsd</cite></dt>
+<dd>Set project type</dd>
+<dt><cite>/noWizard</cite></dt>
+<dd>Do not show the wizard</dd>
+<dt><cite>/openMP</cite></dt>
+<dd>Enable openMP</dd>
+</dl>
+<p>The Visual C++ system provides three different types of "runtimes"
+that must match across all application, library, and DLL code that is
+built. The "configure" program creates a set of build files that are
+consistent for a specific runtime selection.</p>
+<p>The three options for runtime support are:</p>
+<ol class="arabic simple">
+<li>Dynamic Multi-threaded DLL runtimes (VisualDynamicMT), <cite>/mtd</cite> option</li>
+<li>Static Single-threaded runtimes (<cite>VisualStaticST</cite>), <cite>/sts</cite> option</li>
+<li>Static Multi-threaded runtimes (VisualStaticMT), <cite>/mts</cite> option</li>
+<li>Static Multi-threaded DLL runtimes (VisualStaticMTDLL), <cite>/mtsd</cite> option</li>
+</ol>
+<p>In addition to these runtimes, the VisualMagick build environment allows
+you to select whether to include the X11 libraries in the build or not.
+X11 DLLs and headers are provided with the VisualMagick build
+environment. Most Windows users do not use X11 so they will prefer to
+build without X11 support. When X11 is not supported, gm subcommands
+'animate', 'display', and 'import' will not work.</p>
+<p>This leads to five different possible build options, which should
+cover almost any particular situation. The default binary
+distribution is built using #1 from above with the X11 libraries
+excluded. This results build using all DLL's for everything and
+multi-threaded support (the only option for DLL's).</p>
+<p>To do a build for your requirements, simply go to the configure sub-
+directory under VisualMagick and open the configure.dsw workspace
+(for Visual C++ 6.0) or configure.sln (for Visual C++ 7.X through
+9.X). Set the build configuration to "Release" under the</p>
+<blockquote>
+"Build..., Set Active Configuration..." menu.</blockquote>
+<p>Build and execute the configure program and follow the on-screen
+instructions. You should not change any of the defaults unless you have a
+specific reason to do so.</p>
+<p>The configure program provides a button entitled</p>
+<blockquote>
+Edit "magick_config.h"</blockquote>
+<p>Clicking this button brings up magick_config.h in Windows notepad
+for optionally changing any preprocessor defines in GraphicsMagick's
+magick_config.h file. This file is copied to
+<tt class="docutils literal">magick\magick_config.h</tt>. You may safely open
+<tt class="docutils literal">magick\magick_config.h</tt>, modify it, and recompile without
+re-running the configure program. In fact, using Visual Studio to
+edit the copied file may be preferable since it preserves the
+original magick_config.h file.</p>
+<p>Key user tunables in magick_config.h include:</p>
+<blockquote>
+<p>QuantumDepth (default 8)</p>
+<blockquote>
+Specify size of PixelPacket color Quantums (8, 16, or 32) A value of
+8 uses half the memory than 16 and may run 30% faster, but provides
+256 times less color resolution than a value of 16.</blockquote>
+<p>UseInstalledMagick (default undefined)</p>
+<blockquote>
+Define to build a GraphicsMagick which uses registry settings or
+embedded paths to locate installed components (coder modules and
+configuration files). The default is to look for all files in the
+same directory as the executable.</blockquote>
+<p>ProvideDllMain (default undefined)</p>
+<blockquote>
+Define to include a DllMain() function ensures that the GraphicsMagick
+DLL is properly initialized without participation from dependent
+applications. This avoids the requirement to invoke IntializeMagick()
+from dependent applications but only works for DLL builds.</blockquote>
+<p>EnableBrokenCoders (default undefined)</p>
+<blockquote>
+Define to enable broken/dangerous file format support. Only
+enable this if you have complete control over the input files
+and not for arbitrary files such as uploaded from untrusted
+sources via the Internet. Currently this must be enabled to
+enable Adobe Photoshop Format (PSD).</blockquote>
+</blockquote>
+<p>After creating your build environment you can proceed to open the DSW (or
+SLN) file that was generated in the VisualMagick directory and build
+everything from there.</p>
+<p>In the final DSW file you will find a project call "All". In order to
+build everything in the distribution, select this project and make it
+the "active" project. Set the build configuration to the desired one
+(Debug, or Release) and do a "clean" followed by a "build". You should
+do the build in a specific way:</p>
+<blockquote>
+<ol class="arabic simple">
+<li>Make the "All" project the active project (Bold)
+Right click on the All project and select "Set As Active Project"</li>
+<li>Select "Build..., Clean"</li>
+<li>Select "Build..., Build"</li>
+<li>Go get some coffee unless you have a very fast machine!.</li>
+</ol>
+</blockquote>
+<p>The "Clean" step is needed in order to make sure that all of the target
+support libraries are updated with any patches needed to get them to
+compile properly under Visual C++.</p>
+<p>All of the required files that are needed to run any of the command
+line tools will be found in the "bin" subdirectory of the VisualMagick
+subdirectory. This includes EXE, and DLL files. You should be able
+to test the build directly from this directory without having to move
+anything to any of the global SYSTEM or SYSTEM32 areas in the operating
+system installation.</p>
+<p>Note #1:</p>
+<p>The Visual C++ distribution of GraphicsMagick comes with the Magick++
+C++ wrapper by default. This add-on layer has a large number of demo
+and test files that can be found in <tt class="docutils literal"><span class="pre">GraphicsMagick\Magick++\demo</span></tt>, and
+<tt class="docutils literal"><span class="pre">GraphicsMagick\Magick++\tests</span></tt>. There are also a variety of tests that
+use the straight C API as well in <tt class="docutils literal">GraphicsMagick\tests</tt>.</p>
+<p>All of these programs are NOT configured to be built in the default
+workspace created by the configure program. You can cause all of these
+demos and test programs to be built by checking the box in configure
+that says:</p>
+<blockquote>
+"Include all demo and test programs"</blockquote>
+<p>In addition, there is another related checkbox (checked by default)
+that causes all generated project files to be created standalone so
+that they can be copied to other areas of you system.</p>
+<p>This is the checkbox:</p>
+<blockquote>
+"Generate all utility projects with full paths rather then relative
+paths"</blockquote>
+<p>WOW - that a mouthfull - eh?</p>
+<p>Visual C++ uses a concept of "dependencies" that tell it what other
+components need to be build when a particular project is being build. This
+mechanism is also used to ensure that components link properly. In my normal
+development environment, I want to be able to make changes and debug the
+system as a whole, so I like and NEED to use dependencies. However, most
+end users don't want to work this way.</p>
+<p>Instead they really just want to build the package and then get down
+to business working on their application. The solution is to make all
+the utility projects (UTIL_xxxx_yy_exe.dsp) use full absolute paths
+to all the things they need. This way the projects stand on their own
+and can actually be copied and used as templates to get a particular
+custom application compiling with little effort.</p>
+<p>With this feature enabled, you should be able to nab a copy of...</p>
+<blockquote>
+<p><tt class="docutils literal">VisualMagick\utilities\UTIL_gm_xxx_exe.dsp</tt> (for C)</p>
+<blockquote>
+-or-</blockquote>
+<p><tt class="docutils literal"><span class="pre">VisualMagick\Magick++\demo\UTIL_demo_xxx_exe.dsp</span></tt> (for C++)</p>
+</blockquote>
+<p>... and pop it into notepad, modify it (carefully) to your needs and
+be on your way to happy compiling and linking.</p>
+<p>You can feel free to pick any of the standard utilities, tests, or
+demo programs as the basis for a new program by copying the project
+and the source and hacking away.</p>
+<p>The choice of what to use as a starting point is very easy...</p>
+<p>For straight C API command line applications use something from</p>
+<blockquote>
+<p><tt class="docutils literal">GraphicsMagick\tests</tt> or <tt class="docutils literal">GraphicsMagick\utilities</tt> (source code)</p>
+<p><tt class="docutils literal">GraphicsMagick\VisualMagick\tests</tt> or <tt class="docutils literal">GraphicsMagick\Visualmagick\utilities</tt>
+(project - DSP)</p>
+</blockquote>
+<p>For C++ and Magick++ command line applications use something from</p>
+<blockquote>
+<p><tt class="docutils literal"><span class="pre">GraphicsMagick\Magick++\tests</span></tt> or <tt class="docutils literal"><span class="pre">GraphicsMagick\Magick++\demo</span></tt> (source code)</p>
+<p><tt class="docutils literal"><span class="pre">GraphicsMagick\VisualMagick\Magick++\tests</span></tt> or
+<tt class="docutils literal"><span class="pre">GraphicsMagick\VisualMagick\Magick++\demo</span></tt> (project - DSP)</p>
+</blockquote>
+<p>For C++ and Magick++ and MFC windows applications use</p>
+<blockquote>
+<p><tt class="docutils literal">GraphicsMagick\win2k\IMDisplay</tt> (source code)</p>
+<p><tt class="docutils literal">GraphicsMagick\VisualMagick\win32\NtMagick</tt> (project - DSP)</p>
+</blockquote>
+<p>Note #2:</p>
+<p>The GraphicsMagick distribution is very modular. The default
+configuration is there to get you rolling, but you need to make some
+serious choices when you wish to change things around.</p>
+<p>The default options are all targeted at having all the components in one
+place (e.g. the "bin" directory of the VisualMagick build tree). These
+components may be copied to another folder (such as to another computer).</p>
+<p>The folder containing the executables and DLLs should contain the
+following files:</p>
+<blockquote>
+<ol class="arabic simple">
+<li>colors.mgk</li>
+<li>delegates.mgk</li>
+<li>log.mgk</li>
+<li>magic.mgk</li>
+<li>modules.mgk</li>
+<li>type.mgk</li>
+<li>type-ghostscript.mgk (if Ghostscript is used)</li>
+</ol>
+</blockquote>
+<p>The "bin" folder should contains all EXE's and DLL's as well as the
+very important "modules.mgk" file.</p>
+<p>With this default setup, you can use any of the command line tools
+and run scripts as normal. You can actually get by quite nicely this
+way by doing something like <tt class="docutils literal">pushd <span class="pre">e:\xxx\yyy\bin</span></tt> in any scripts you
+write to execute "out of" this directory.</p>
+<p>By default the core of GraphicsMagick on Win32 always looks in the place
+were the exe program is run from in order to find all of the files as
+well as the DLL's it needs.</p>
+</blockquote>
+</div>
+<div class="section" id="environment-variables">
+<h2><a class="toc-backref" href="#id20">Environment Variables</a></h2>
+<blockquote>
+<p>You can use the "System" control panel to allow you to add and delete
+what is in any of the environment variables. You can even have user
+specific environment variables if you wish.</p>
+<p>PATH</p>
+<blockquote>
+<p>This sets the default list of places were Windows looks for EXE's and
+DLL's. Windows CMD shell seems to look in the "current" directory first
+- no matter what, which may make it unnecessary to update the PATH. If
+you wish to run any of utilities from another location then you must
+add the path to your "bin" directory in. For instance, you might add:</p>
+<blockquote>
+<tt class="docutils literal"><span class="pre">D:\Devel\GraphicsMagick\VisualMagick\bin</span></tt></blockquote>
+<p>to do this for the default build environment like I do.</p>
+</blockquote>
+<p>MAGICK_HOME</p>
+<blockquote>
+<p>If all you do is modify the PATH variable, the first problem you
+will run into is that GraphicsMagick may not be able to find any of
+its "modules. Modules are all the IM_MOD*.DLL files you see in the
+distribution. There is one of these for each and every file format
+that GraphicsMagick supports. This environment variable tells the system
+were to look for these DLL's. The compiled in "default" is "execution
+path" - which says - look in the same place that the application is
+running "in". If you are running from somewhere other then "bin" -
+this will no longer work and you must use this variable. If you elect
+to leave the modules in the same place as the EXE's (a good idea)
+then you can simply set this to the same place
+as you did the PATH variable. In my case:</p>
+<blockquote>
+<tt class="docutils literal"><span class="pre">D:\\GraphicsMagick\coders</span></tt></blockquote>
+<p>This is also the place were GraphicsMagick expects to find the
+"colors.mgk", "delegates.mgk", "magic.mgk", "modules.mgk", and
+"type.mgk" files.</p>
+<p>One cool thing about the modules build of GraphicsMagick is that you can
+now leave out file formats and lighten you load. If all you ever need
+is GIF and JPEG, then simply drop all the other DLL's into the local
+trash can and get on with your life.</p>
+<p>WARNING: Always keep the "xc" format, since GM uses it for internal
+purposes.</p>
+</blockquote>
+<p>ALSO. You can elect to changes these things the good old "hard-coded"
+way. Two #defines are applicable.</p>
+<p>defines.h has</p>
+<blockquote>
+<tt class="docutils literal">#define MagickConfigurePath <span class="pre">"c:\\GraphicsMagick\\"</span></tt></blockquote>
+<p>To view any image in a Microsoft window, type</p>
+<blockquote>
+<tt class="docutils literal">gm convert image.ext win:</tt></blockquote>
+<p>Make sure Ghostscript is installed, otherwise, you will be unable to
+convert or view a Postscript document, and Postscript standard fonts will
+not be available.</p>
+<p>You may use any standard web browser (e.g. Internet Explorer) to browse
+the GraphicsMagick documentation.</p>
+<p>The Win2K executables will work under Windows '98 and later.</p>

+IM operations. The IM COM+ component simply provides access to the
+<a class="reference external" href="convert.html">convert</a>, composite, <a class="reference external" href="mogrify.html">mogrify</a>, <a class="reference external" href="identify.html">identify</a>, and <a class="reference external" href="montage.html">montage</a> tools,
+efficiently executing them as part of your process, rather than as
+external programs. The way you use it is exactly the same. You pass it a
+list of strings including filenames and various options and it does the
+job. In fact, you can take any existing batch scripts that use the
+command line tools and translate them into the equivalent calls to the
+COM+ object in a matter of minutes. Beyond that, there is also a way to
+pass in and retrieve images in memory in the form of standard smart
+arrays (byte arrays). Samples are provided, to show both the simple and
+more elaborate forms of access.</p>
+<p><em>GraphicsMagick</em> provides a statically-built ImageMagick object as part of
+its "utils" <a class="reference external" href="INSTALL-windows.html">Windows installation package</a>. When this package is
+installed, <em>ImageMagickObject</em> and its sample programs are installed to</p>
+<pre class="literal-block">
+c:\Program Files\GraphicsMagick-1.3-Q16\ImageMagickObject
+</pre>
+<p>by default (path shown is for the Q:16 build). <em>ImageMagickObject</em> is
+registered if the checkbox for "Register ImageMagickObject" is checked at
+install time.</p>
+<p>You may execute the sample program from the Windows Command Shell like:</p>
+<pre class="literal-block">
+cscript SimpleTest.vbs
+</pre>
+<p>Since the <em>GraphicsMagick</em> utility command line parsers are incorporated
+within <em>ImageMagickObject</em>, please refer to the command line <a class="reference external" href="utilities.html">utility
+documentation</a> to learn how to use it. The sample VBS scripts show how
+the object should be called and used and have lots of comments.</p>
+<p>For C++ programmers - have a look at the MagickCMD.cpp command line
+utility for an example of how to call the object from C++. This is a bit
+complex because the object requires a variable size list of BSTR's to
+emulate the command line argc, argv style calling conventions of the COM
+component which is more complex in C++ then in VBS or VB.</p>
+</div>
+<div class="section" id="other-goodies">
+<h1>Other goodies...</h1>
+<p>MagickCMD is a C++ sample, but it can also server as a replacement for
+all the other command line utilities in most applications. Instead of
+using "<tt class="docutils literal">convert xxxx yyyy</tt>" you can use "<tt class="docutils literal">MagickCMD convert xxxx
+yyyy</tt>" instead. MagickCMD calls the COM object to get the job done. This
+small tight combination replaces the entire usual binary distribution in
+just a few megabytes.</p>
+</div>
+<div class="section" id="building-imagemagickobject-from-source">
+<h1>Building ImageMagickObject From Source</h1>
+<p>The source code for <em>ImageMagickObject</em> is available from <em>GraphicsMagick</em>
+CVS, or as part of the <em>GraphicsMagick</em> Windows source package. Once the
+source code has been retrieved and extracted, the source for
+<em>ImageMagickObject</em> may be found hidden in the directory
+"<tt class="docutils literal">GraphicsMagick\contrib\win32\ATL7ImageMagickObject</tt>", however,
+<em>GraphicsMagick</em> itself must be built using the "static-multithread"
+(VisualStaticMT) build configuration. Building <em>ImageMagickObject</em>
+requires Microsoft Visual C++ 7.0 as delivered with Microsoft's Visual
+Studio .net package. See the Windows compilation instructions in order to
+get <em>GraphicsMagick</em> itself built before building <em>ImageMagickObject</em>.</p>
+<p>Once the VisualStaticMT project has been built, <em>ImageMagickObject</em> may
+be built by following the procedure:</p>
+<pre class="literal-block">
+cd GraphicsMagick\contrib\win32\ATL7ImageMagickObject
+BuildImageMagickObject release
+</pre>
+<p>This procedure assumes that the VisualStaticMT project has been built
+using the "release" setting for an optimized build. If the "debug"
+setting was used for a debug build, then specify the argument "debug"
+instead.</p>
+<p>To register the DLL as a COM+ server use</p>
+<pre class="literal-block">
+regsvr32 /c /s ImageMagickObject.dll
+</pre>
+<p>To unregister the DLL use</p>
+<pre class="literal-block">
+regsvr32 /u /s ImageMagickObject.dll
+</pre>
+<p>The MagickCMD sample program operates similarly to the gm.exe program,
+and is a great way to exercise <em>ImageMagickObject</em> to verify that it is
+working.</p>
+<p>Sometime in the future, MagickCMD may assume the place of gm.exe in the
+"utils" distribution in order to decrease the overall package size.</p>

+<p>Blob provides the means to contain any opaque data. It is named after
+the term <a class="reference external" href="http://en.wikipedia.org/wiki/Binary_large_object">Binary Large OBject</a> commonly used to
+describe unstructured data (such as encoded images) which are stored
+in a database. While the function of Blob is very simple (store a
+pointer and and size associated with allocated data), the Blob class
+provides some very useful capabilities. In particular, it is fully
+reference counted just like the Image class.</p>
+<p>The Blob class supports value assignment while preserving any
+outstanding earlier versions of the object. Since assignment is via a
+pointer internally, Blob is efficient enough to be stored directly in
+an STL container or any other data structure which requires
+assignment. In particular, by storing a Blob in an <a class="reference external" href="http://www.sgi.com/tech/stl/AssociativeContainer.html">associative
+container</a>
+(such as STL's <a class="reference external" href="http://www.sgi.com/tech/stl/Map.html">map</a>) it is
+possible to create simple indexed in-memory "database" of Blobs.</p>
+<p>Magick++ currently uses Blob to contain encoded images (e.g. JPEG) as
+well as ICC and IPTC profiles. Since Blob is a general-purpose class,
+it may be used for other purposes as well.</p>
+<p>The following is the definition of the Magick::Blob class:</p>
+<pre class="literal-block">
+class Blob
+{
+
+public:
+
+ enum Allocator
+ {
+ MallocAllocator,
+ NewAllocator
+ };
+
+ // Default constructor
+ Blob ( void );
+
+ // Construct object with data, making a copy of the supplied data.
+ Blob ( const void* data_, size_t length_ );
+
+ // Copy constructor (reference counted)
+ Blob ( const Blob& blob_ );
+
+ // Destructor (reference counted)
+ virtual ~Blob ();
+
+ // Assignment operator (reference counted)
+ Blob& operator= ( const Blob& blob_ );
+
+ // Update object contents from Base64-encoded string representation.
+ void base64 ( const std::string base64_ );
+ // Return Base64-encoded string representation.
+ std::string base64 ( void );
+
+ // Update object contents, making a copy of the supplied data.
+ // Any existing data in the object is deallocated.
+ void update ( const void* data_, size_t length_ );
+
+ // Update object contents, using supplied pointer directly (no
+ // copy). Any existing data in the object is deallocated. The user
+ // must ensure that the pointer supplied is not deleted or
+ // otherwise modified after it has been supplied to this method.
+ // Specify allocator_ as "MallocAllocator" if memory is allocated
+ // via the C language malloc() function, or "NewAllocator" if
+ // memory is allocated via C++ 'new'.
+ void updateNoCopy ( void* data_, size_t length_,
+ Allocator allocator_ = NewAllocator );
+
+ // Obtain pointer to data. The user should never try to modify or
+ // free this data since the Blob class manages its own data. The
+ // user must be finished with the data before allowing the Blob to
+ // be destroyed since the pointer is invalid once the Blob is
+ // destroyed.
+ const void* data ( void ) const;
+
+ // Obtain data length
+ size_t length ( void ) const;
+
+};

+<p>The CoderInfo class supports obtaining information about
+GraphicsMagick support for an image format (designated by a magick
+string). It may be used to provide support for a specific named format
+(provided as an argument to the constructor), or as an element of a
+container when format support is queried using the coderInfoList()
+templated function.</p>
+<p>The following code fragment illustrates how CoderInfo may be used:</p>
+<pre class="literal-block">
+CoderInfo info("GIF");
+cout << info->name() << ": (" << info->description() << ") : ";
+cout << "Readable = ";
+if ( info->isReadable() )

+ cout << "false";
+cout << ", ";
+cout << "Writable = ";
+if ( info->isWritable() )
+ cout << "true";
+else
+ cout << "false";
+cout << ", ";
+cout << "Multiframe = ";
+if ( info->isMultiframe() )
+ cout << "true";
+else
+ cout << "false";
+cout << endl;
+</pre>
+<p>The definition of class 'Magick::CoderInfo' is:</p>
+<pre class="literal-block">

+<!-- This text is in reStucturedText format, so it may look a bit odd. -->
+<!-- See http://docutils.sourceforge.net/rst.html for details. -->
+<p>Color is the base color class in Magick++. It is a simple container
+class for the pixel red, green, blue, and alpha values scaled to fit
+GraphicsMagick's Quantum (number of bits in a color component value)
+size. Normally users will instantiate a class derived from Color which
+supports the color model that fits the needs of the application. The
+Color class may be constructed directly from an X11-style color
+string. As a perhaps odd design decision, the value transparent black
+is considered to represent an unset value (invalid color) in many
+cases. This choice was made since it avoided using more memory. The
+default Color constructor constructs an invalid color
+(i.e. transparent black) and may be used as a parameter in order to
+remove a color setting.</p>
+<div class="section" id="quantum">
+<h1>Quantum</h1>
+<p>The base type used to represent color samples in GraphicsMagick is the
+Quantum type. Pixels are represented by a structure of Quantum
+values. For example, an RGB pixel contains red, green, and blue
+quantums, while an RGBA pixel contains red, green, blue, and opacity
+quantums. The maximum value that a Quantum can attain is specified by
+a constant value represented by the MaxRGB define, which is itself
+determined by the number of bits in a Quantum. The QuantumDepth build
+option determines the number of bits in a Quantum.</p>
+</div>
+<div class="section" id="pixelpacket">
+<h1>PixelPacket</h1>
+<p>PixelPacket is the internal representation of a pixel in
+GraphicsMagick. GraphicsMagick may be compiled to support 32, 64, or
+128 bit pixels of type PixelPacket. This is controlled by the value of
+the QuantumDepth define. The default is 32 bit pixels
+(QuantumDepth=8), which provides the best performance and the least
+resource consumption. If additional color precision or range is
+desired, then GraphicsMagick may be compiled with QuantumDepth=16 or
+QuantumDepth=32. The following table shows the relationship between
+QuantumDepth, the type of Quantum, and the overall PixelPacket size:</p>
+<table border="1" class="docutils">
+<caption>Effect Of QuantumDepth Values</caption>

+<h1>Color Class</h1>
+<p>The Color base class is not intended to be used directly. Normally a
+user will construct a derived class or inherit from this class. Color
+arguments are must be scaled to fit the Quantum size according to the
+range of MaxRGB. The Color class contains a pointer to a PixelPacket,
+which may be allocated by the Color class, or may refer to an existing
+pixel in an image.</p>
+<p>An alternate way to construct the class is via an X11-compatible color
+specification string (e.g. Color(“red”) or Color (“#FF0000”)). Since
+the class may be constructed from a string, convenient strings may be
+passed in place of an explicit Color object in methods which accept a
+reference to Color. Color may also be converted to a std::string for
+convenience in user interfaces, and for saving settings to a text
+file.</p>
+<p>The following is the definition of the Color class:</p>
+<pre class="literal-block">

+int MagickDLLDecl operator >= ( const Magick::Color& left_, const Magick::Color& right_ );
+int MagickDLLDecl operator <= ( const Magick::Color& left_, const Magick::Color& right_ );

+<p>Drawable provides a convenient interface for preparing vector, image,
+or text arguments for the Image::draw() method. Each instance of a
+Drawable sub-class represents a single drawable object. Drawable
+objects may be drawn "one-by-one" via multiple invocations of the
+Image <a class="reference external" href="Image.html#draw">draw()</a> method, or may be drawn
+"all-at-once" by passing a list of Drawable objects to the Image
+<a class="reference external" href="Image.html#draw">draw()</a> method. The one-by-one approach is
+convenient for simple drawings, while the list-based approach is
+appropriate for drawings which require more sophistication.</p>
+<p>The following is an example using the Drawable subclasses with a
+one-by-one approach to draw the following figure:</p>
+<img alt="Figure showing drawing example" src="Drawable_example_1.png" style="width: 300px; height: 200px;" />
+<pre class="literal-block">
+#include <string>
+#include <iostream>
+#include <Magick++.h>
+
+using namespace std;
+using namespace Magick;
+
+int main(int /*argc*/,char **argv)
+{
+ try {
+ InitializeMagick(*argv);
+
+ // Create base image (white image of 300 by 200 pixels)
+ Image image( Geometry(300,200), Color("white") );
+
+ // Set draw options
+ image.strokeColor("red"); // Outline color
+ image.fillColor("green"); // Fill color
+ image.strokeWidth(5);
+
+ // Draw a circle
+ image.draw( DrawableCircle(100,100, 50,100) );
+
+ // Draw a rectangle
+ image.draw( DrawableRectangle(200,200, 270,170) );
+
+ // Display the result
+ image.display( );
+ }
+ catch( exception &error_ )
+ {
+ cout << "Caught exception: " << error_.what() << endl;
+ return 1;
+ }
+
+ return 0;
+}
+</pre>
+<p>Since Drawable is an object it may be saved in an array or a list for
+later (perhaps repeated) use. The following example shows how to draw
+the same figure using the list-based approach:</p>
+<pre class="literal-block">
+#include <string>

+ try {

+ InitializeMagick(*argv);
+
+ // Create base image (white image of 300 by 200 pixels)
+ Image image( Geometry(300,200), Color("white") );
+
+ // Construct drawing list
+ std::list<Magick::Drawable> drawList;
+
+ // Add some drawing options to drawing list
+ drawList.push_back(DrawableStrokeColor("red")); // Outline color
+ drawList.push_back(DrawableStrokeWidth(5)); // Stroke width
+ drawList.push_back(DrawableFillColor("green")); // Fill color
+
+ // Add a Circle to drawing list
+ drawList.push_back(DrawableCircle(100,100, 50,100));
+
+ // Add a Rectangle to drawing list
+ drawList.push_back(DrawableRectangle(200,100, 270,170));
+
+ // Draw everything using completed drawing list
+ image.draw(drawList);
+
+ // Display the result
+ image.display( );
+ }

+<p>The <em>ColorspaceType</em> enumeration is used to specify the colorspace that

+the colorspace when encoding an output image. Colorspaces are ways of
+describing colors to fit the requirements of a particular application
+(e.g. Television, offset printing, color monitors). Color reduction,
+by default, takes place in the <em>RGBColorspace</em>. Empirical evidence
+suggests that distances in color spaces such as <em>YUVColorspace</em> or
+<em>YIQColorspace</em> correspond to perceptual color differences more closely
+han do distances in RGB space. These color spaces may give better
+results when color reducing an image. Refer to quantize for more
+details.</p>
+<p>When encoding an output image, the colorspaces <em>RGBColorspace</em>,
+<em>CMYKColorspace</em>, <em>GRAYColorspace</em>, or <em>YCbCrColorspace</em> may be
+specified. The CMYKColorspace option is only applicable when writing

+<!-- -*- mode: rst -*- -->

+<p><em>Exception</em> represents the base class of objects thrown when
+Magick++ reports an error. Magick++ throws C++ exceptions synchronous
+with the operation where the error occurred. This allows errors to be
+trapped within the enclosing code (perhaps the code to process a
+single image) while allowing the code to be written with a simple
+coding style.</p>
+<p>A try/catch block should be placed around any sequence of operations
+which can be considered an important body of work. For example, if
+your program processes lists of images and some of these images may be
+defective, by placing the try/catch block around the entire sequence
+of code that processes one image (including instantiating the image
+object), you can minimize the overhead of error checking while
+ensuring that all objects created to deal with that object are safely
+destroyed (C++ exceptions unroll the stack until the enclosing try
+block, destroying any objects on the stack).</p>
+<p>Note that any objects allocated via 'new' with a pointer on the stack
+are not automatically destroyed by unrolling the stack via a C++
+exception so that it may be necessary to catch the exception at each
+level, destroy any objects allocated via 'new' (or malloc()) and then
+re-throw the exception. This includes constructors which might
+encounter an exception while the object is being constructed and
+should destroy any already-allocated data. Magick++ classes are
+designed to be <strong>very</strong> tiny so it is recommended to automatically
+allocate them on the stack when possible rather than via 'new'.</p>
+<p>The pseudo code for the main loop of your program may look like:</p>
+<pre class="literal-block">
+ using namespace std;
+ for infile in list
+ {
+ try {
+ // Construct an image instance first so that we don't have to worry
+ // about object construction failure due to a minor warning exception
+ // being thrown.
+ Magick::Image image;
+
+ // Determine if Warning exceptions are thrown.
+ // Use is optional. Set to true to block Warning exceptions.
+ image.quiet( false );
+
+ try {
+ // Try reading image file
+ image.read(infile);
+ }
+ catch( Magick::WarningCoder &warning )
+ {
+ // Process coder warning while loading file (e.g. TIFF warning)
+ // Maybe the user will be interested in these warnings (or not).
+ // If a warning is produced while loading an image, the image
+ // can normally still be used (but not if the warning was about
+ // something important!)
+ cerr << “Coder Warning: “ << warning.what() << endl;
+ }
+ catch( Magick::Warning &warning )
+ {
+ // Handle any other Magick++ warning.
+ cerr << “Warning: “ << warning.what() << endl;
+ }
+ catch( Magick::ErrorFileOpen &error )
+ {
+ // Process Magick++ file open error
+ cerr << “Error: “ << error.what() << endl;
+ continue; // Try next image.
+ }
+ try {
+ image.rotate(90);
+ image.write(“outfile”);
+ }
+ catch ( MagickExeption & error)
+ {
+ // Handle problem while rotating or writing outfile.
+ cerr << “Caught Magick++ exception: “ << error.what() << endl;
+ }
+ }
+ catch( std::exception &error )
+ {
+ // Process any other exceptions derived from standard C++ exception
+ cerr << “Caught C++ STD exception: “ << error.what() << endl;
+ }
+ catch( ... )
+ {
+ // Process *any* exception (last-ditch effort). There is not a lot
+ // you can do here other to retry the operation that failed, or exit
+ // the program.
+ }
+ }
+
+The desired location and number of try/catch blocks in your program
+depends how sophisticated its error handling must be. Very simple
+programs may use just one try/catch block.
+</pre>
+<p>The <em>Exception</em> class is derived from the C++ standard
+<em>std::exception</em> class. This means that it contains a C++ string
+containing additional information about the error (e.g to display to
+the user). Obtain access to this string via the what() method. For
+example:</p>
+<pre class="literal-block">
+catch( Exception &error_ )
+{
+ cout << "Caught exception: " << error_.what() << endl;
+}
+</pre>
+<p>The classes <em>Warning</em> and <em>Error</em> derive from the <em>Exception</em>
+class. Exceptions derived from <em>Warning</em> are thrown to represent
+non-fatal errors which may effect the completeness or quality of the
+result (e.g. one image provided as an argument to montage is
+defective). In most cases, a <em>Warning</em> exception may be ignored by
+catching it immediately, processing it (e.g. printing a diagnostic)
+and continuing on. Exceptions derived from <em>Error</em> are thrown to
+represent fatal errors that can not produce a valid result
+(e.g. attempting to read a file which does not exist).</p>
+<p>The specific derived exception classes are shown in the following tables:</p>

+and are used to specify the distance of the placement coordinate from

+offsets are measured from the indicated edge of the object to the
+corresponding edge of the image. The X offset may be specified in the
+following ways:</p>

+<h1>GraphicsMagick Extensions To X11 Geometry Specifications</h1>
+<p>GraphicsMagick has added a number of qualifiers to the standard
+geometry string for use when resizing images. The form of an extended
+geometry string is
+"<width>x<height>{+-}<xoffset>{+-}<yoffset>{%}{@}{!}{^}{<}{>}". Extended
+geometry strings should only be used when resizing an image. Using an

+<h1>Postscript Page Size Extension To Geometry Specifications</h1>
+<p>Any geometry string specification supplied to the Geometry constructor
+is considered to be a Postscript page size nickname if the first
+character is not numeric. The page size nickname is not case
+sensitive. The Geometry constructor converts these page size
+specifications into the equivalent numeric geometry string
+specification (preserving any offset component) prior to conversion to
+the internal object format. Postscript page size specifications are
+short-hand for the pixel geometry required to fill a page of that
+size. Since the 11x17 inch page size used in the US starts with a
+digit, it is not supported as a Postscript page size
+nickname. Instead, substitute the geometry specification "792x1224>"
+when 11x17 output is desired.</p>

+<h1><a class="toc-backref" href="#id9">Introduction</a></h1>
+<p>Image is the primary object in Magick++ and represents a single image
+frame (see <a class="reference external" href="ImageDesign.html">image design</a>). The <a class="reference external" href="STL.html">STL</a> interface must be used to
+operate on image sequences or images (e.g. of format GIF, TIFF, MIFF,
+Postscript, & MNG) which are comprized of multiple image
+frames. Individual frames of a multi-frame image may be requested by
+adding array-style notation to the end of the file name
+(e.g. "animation.gif[3]" retrieves the fourth frame of a GIF
+animation. Various image manipulation operations may be applied to
+the image. Attributes may be set on the image to influence the
+operation of the manipulation operations. The <a class="reference external" href="Pixels.html">Pixels</a> class provides
+low-level access to image pixels. As a convenience, including
+<Magick++.h> is sufficient in order to use the complete Magick++
+API. The Magick++ API is enclosed within the Magick namespace so you
+must either add the prefix " Magick:: " to each class/enumeration name
+or add the statement " using namespace Magick;" after including the
+Magick++.h header.</p>
+<p>The InitializeMagick() function <em>MUST</em> be invoked before constructing
+any Magick++ objects. This used to be optional, but now it is
+absolutely required. This function initalizes semaphores and
+configuration information necessary for the software to work
+correctly. Failing to invoke InitializeMagick() is likely to lead to
+a program crash or thrown assertion. If the program resides in the
+same directory as the GraphicsMagick files, then argv[0] may be passed
+as an argument so that GraphicsMagick knows where its files reside,
+otherwise NULL may be passed and GraphicsMagick will try to use other
+means (if necessary).</p>
+<p>The preferred way to allocate Image objects is via automatic
+allocation (on the stack). There is no concern that allocating Image
+objects on the stack will excessively enlarge the stack since Magick++
+allocates all large data objects (such as the actual image data) from
+the heap. Use of automatic allocation is preferred over explicit
+allocation (via new) since it is much less error prone and allows use
+of C++ scoping rules to avoid memory leaks. Use of automatic
+allocation allows Magick++ objects to be assigned and copied just like
+the C++ intrinsic data types (e.g. 'int '), leading to clear and easy
+to read code. Use of automatic allocation leads to naturally
+exception-safe code since if an exception is thrown, the object is
+automatically deallocated once the stack unwinds past the scope of the
+allocation (not the case for objects allocated via new ).</p>
+<p>Image is very easy to use. For example, here is a the source to a
+program which reads an image, crops it, and writes it to a new file
+(the exception handling is optional but strongly recommended):</p>
+<pre class="literal-block">
+#include <Magick++.h>
+#include <iostream>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ // Initialize the API. Can pass NULL if argv is not available.
+ InitializeMagick(*argv);
+
+ // Construct the image object. Seperating image construction from the
+ // the read operation ensures that a failure to read the image file
+ // doesn't render the image object useless.
+ Image image;
+
+ try {
+ // Determine if Warning exceptions are thrown.
+ // Use is optional. Set to true to block Warning exceptions.
+ image.quiet( false );
+
+ // Read a file into image object
+ image.read( "girl.gif" );
+
+ // Crop the image to specified size (width, height, xOffset, yOffset)
+ image.crop( Geometry(100,100, 100, 100) );
+
+ // Write the image to a file
+ image.write( "x.gif" );
+ }
+ catch( Exception &error_ )
+ {
+ cout << "Caught exception: " << error_.what() << endl;
+ return 1;
+ }
+ return 0;
+}
+</pre>
+<p>The following is the source to a program which illustrates the use of
+Magick++'s efficient reference-counted assignment and copy-constructor
+operations which minimize use of memory and eliminate unncessary copy
+operations (allowing Image objects to be efficiently assigned, and
+copied into containers). The program accomplishes the following:</p>
+<ol class="arabic simple">
+<li>Read master image.</li>
+<li>Assign master image to second image.</li>
+<li>Zoom second image to the size 640x480.</li>
+<li>Assign master image to a third image.</li>
+<li>Zoom third image to the size 800x600.</li>
+<li>Write the second image to a file.</li>
+<li>Write the third image to a file.</li>
+</ol>
+<pre class="literal-block">
+#include <Magick++.h>
+#include <iostream>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ InitializeMagick(*argv);
+ Image master("horse.jpg");
+ Image second = master;
+ second.zoom("640x480");
+ Image third = master;
+ third.zoom("800x600");
+ second.write("horse640x480.jpg");
+ third.write("horse800x600.jpg");
+ return 0;
+}
+</pre>
+<p>During the entire operation, a maximum of three images exist in memory
+and the image data is never copied.</p>
+<p>The following is the source for another simple program which creates a
+100 by 100 pixel white image with a red pixel in the center and writes
+it to a file:</p>
+<pre class="literal-block">
+#include <Magick++.h>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ InitializeMagick(*argv);
+ Image image( "100x100", "white" );
+ image.pixelColor( 49, 49, "red" );
+ image.write( "red_pixel.png" );
+ return 0;
+}
+</pre>
+<p>If you wanted to change the color image to grayscale, you could add
+the lines:</p>
+<pre class="literal-block">
+image.quantizeColorSpace( GRAYColorspace );
+image.quantizeColors( 256 );
+image.quantize( );
+</pre>
+<p>or, more simply:</p>
+<pre class="literal-block">
+image.type( GrayscaleType );
+</pre>
+<p>prior to writing the image.</p>
+</div>
+<div class="section" id="blobs">
+<h1><a class="toc-backref" href="#id10">BLOBs</a></h1>
+<p>While encoded images (e.g. JPEG) are most often written-to and
+read-from a disk file, encoded images may also reside in
+memory. Encoded images in memory are known as BLOBs (Binary Large
+OBjects) and may be represented using the <a class="reference external" href="Blob.html">Blob</a> class. The encoded
+image may be initially placed in memory by reading it directly from a
+file, reading the image from a database, memory-mapped from a disk
+file, or could be written to memory by Magick++. Once the encoded
+image has been placed within a <a class="reference external" href="Blob.html">Blob</a>, it may be read into a Magick++
+Image via a constructor or read() . Likewise, a Magick++ image may be
+written to a <a class="reference external" href="Blob.html">Blob</a> via write().</p>
+<p>An example of using Image to write to a <a class="reference external" href="Blob.html">Blob</a> follows:</p>
+<pre class="literal-block">
+#include <Magick++.h>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ // Read GIF file from disk
+ Image image( "giraffe.gif" );
+
+ // Write to BLOB in JPEG format
+ Blob blob;
+ image.magick( "JPEG" ) // Set JPEG output format
+ image.write( &blob );
+
+ [ Use BLOB data (in JPEG format) here ]
+
+ return 0;
+}
+</pre>
+<p>likewise, to read an image from a <a class="reference external" href="Blob.html">Blob</a>, you could use one of the
+following examples:</p>
+<p>[ Entry condition for the following examples is that data is pointer
+to encoded image data and length represents the size of the data ]</p>
+<pre class="literal-block">
+Blob blob( data, length );
+Image image( blob );
+</pre>
+<p>or</p>
+<pre class="literal-block">
+Blob blob( data, length );
+Image image;
+image.read( blob);
+</pre>
+<p>Some images do not contain their size or format so the size and format
+must be specified in advance:</p>
+<pre class="literal-block">
+Blob blob( data, length );
+Image image;
+image.size( "640x480")

+<p>Segment (coalesce similar image components) by analyzing the

+homogeneous with the fuzzy c-means technique. A histogram is built
+for the image. This histogram is filtered to reduce noise and a
+second derivative of the histogram plot is built and used to identify
+potential cluster colors (peaks in the histogram). The cluster colors
+are then validated by scanning through all of the pixels to see how
+many pixels fall within each cluster. Some candidate cluster colors
+may not match any of the image pixels at all and should be discarded.
+Specify <cite>clusterThreshold</cite>, as the number of pixels matching a cluster
+color in order for the cluster to be considered
+valid. <cite>SmoothingThreshold</cite> eliminates noise in the second derivative
+of the histogram. As the value is increased, you can expect a smoother

+<h1><a class="toc-backref" href="#id15">Low-Level Image Pixel Access</a></h1>
+<p>Image pixels (of type <a class="reference external" href="PixelPacket.html">PixelPacket</a> ) may be accessed directly via
+the Image Pixel Cache . The image pixel cache is a rectangular window
+into the actual image pixels (which may be in memory, memory-mapped
+from a disk file, or entirely on disk). Two interfaces exist to access
+the Image Pixel Cache. The interface described here (part of the Image
+class) supports only one view at a time. See the <a class="reference external" href="Pixels.html">Pixels</a> class for a
+more abstract interface which supports simultaneous pixel views (up to
+the number of rows). As an analogy, the interface described here
+relates to the <a class="reference external" href="Pixels.html">Pixels</a> class as stdio's gets() relates to
+fgets(). The <a class="reference external" href="Pixels.html">Pixels</a> class provides the more general form of the
+interface.</p>
+<p>Obtain existing image pixels via getPixels(). Create a new pixel
+region using setPixels().</p>
+<p>In order to ensure that only the current generation of the image is
+modified, the Image's modifyImage() method should be invoked to reduce
+the reference count on the underlying image to one. If this is not
+done, then it is possible for a previous generation of the image to be
+modified due to the use of reference counting when copying or
+constructing an Image.</p>
+<p>Depending on the capabilities of the operating system, and the
+relationship of the window to the image, the pixel cache may be a copy
+of the pixels in the selected window, or it may be the actual image
+pixels. In any case calling syncPixels() insures that the base image
+is updated with the contents of the modified pixel cache. The method
+readPixels() supports copying foreign pixel data formats into the
+pixel cache according to the QuantumTypes. The method writePixels()
+supports copying the pixels in the cache to a foreign pixel
+representation according to the format specified by QuantumTypes.</p>
+<p>The pixel region is effectively a small image in which the pixels may
+be accessed, addressed, and updated, as shown in the following
+example:</p>
+<p><img alt="pixel_cache" src="Cache.png" /></p>
+<pre class="literal-block">
+// Construct image based on an existing file
+Image image("cow.png");
+
+// Ensure that there are no other references to this image.
+image.modifyImage();
+
+// Set the image type to TrueColor DirectClass representation.
+image.type(TrueColorType);
+
+// Request pixel region with size 60x40, and top origin at 20x30
+int columns = 60;
+PixelPacket *pixel_cache = image.getPixels(20,30,columns,40);
+
+// Set pixel at column 5, and row 10 in the pixel cache to red.
+int column = 5;
+int row = 10;
+PixelPacket *pixel = pixel_cache+row*columns+column;
+*pixel = Color("red");
+
+// Save changes to underlying image .
+image.syncPixels();
+
+ // Save updated image to file.
+image.write("horse.png");

+Explicit Logging Configuration And Callbacks
+--------------------------------------------
+
+It is sometimes useful for a program to not have to depend on a
+configuration file for configuring logging ("tracing"). One reason
+for this is because until a logging configuration file has been found
+and loaded, default logging parameters are used. Another reason is
+that in some configurations, it is useful for each instance of a
+program to use its own logging configuration. To make this possible,
+the Magick++ library provides pass-through functions which allow
+setting the logging defaults *before* InitializeMagick() is called.
+Setting logging defaults after InitializeMagick() is called has no
+purpose since they will not be used.

+The following C++ pass-through functions are available"

+<p>The class Magick::Image is a simple handle which points to a
+reference-counted image representation. This allows multiple
+Magick::Image instances to share the same image and attributes. At the
+point in time that the image data, or image attributes are modified
+and the current reference count is greater than one, the image data
+and attributes are copied to create a new image with a reference count
+of one and the reference count on the old image is decremented. If the
+reference count on the old image becomes zero, then the associated
+reference and data are deleted. This strategy represents a simple (but
+effective) form of garbage collection.</p>

+<p>A montage is a single image which is composed of thumbnail images
+composed in a uniform grid. The size of the montage image is
+determined by the size of the individual thumbnails and the number of
+rows and columns in the grid.</p>
+<p>The following illustration shows a montage consisting of three columns
+and two rows of thumbnails rendered on a gray background:</p>
+<img alt="Figure showing framed montage" class="align-center" src="montage-sample-framed.jpg" style="width: 378.0px; height: 238.0px;" />
+<p>Montages may be either "plain" (undecorated thumbnails) or "framed"
+(decorated thumbnails). In order to more easily understand the options
+supplied to MontageImages(), montage options are supplied by two
+different classes: Magick::Montage and Magick::MontageFramed.</p>
+<div class="section" id="plain-montages">

+<p>Unframed thumbnails consist of four components: the thumbnail image,
+the thumbnail border, an optional thumbnail shadow, and an optional
+thumbnail label area.</p>

+<p>The PixelPacket structure is used to represent DirectClass pixels in
+GraphicsMagick. GraphicsMagick may be compiled to support 32, 64, or
+even 128 bit pixels. The size of PixelPacket is controlled by the
+value of the QuantumDepth define. The default build depth is 32 bit
+pixels, which provides minumum ("web standard") accuracy, least memory
+consumption, and best performance. If deeper images need to be
+supported or more mathematical accuracy is desired, then
+GraphicsMagick may be compiled with QuantumDepth=16 or
+QuantumDepth=32.</p>
+<p>The following table shows the relationship between QuantumDepth, the
+type of Quantum, and the overall PixelPacket size:</p>
+<table border="1" class="docutils">

+<p>The Pixels class provides efficient access to raw image pixels. Image
+pixels (of type <a class="reference external" href="PixelPacket.html">PixelPacket</a>) may be accessed
+directly via the Image Pixel Cache. The image pixel cache is a
+rectangular window (a view) into the actual image pixels (which may be
+in memory, memory-mapped from a disk file, or entirely on
+disk). Obtain existing image pixels via get(). Create a new pixel
+region using set().</p>
+<p>Depending on the capabilities of the operating system, and the
+relationship of the window to the image, the pixel cache may be a copy
+of the pixels in the selected window, or it may be the actual image
+pixels. In any case calling sync() insures that the base image is
+updated with the contents of the modified pixel cache. The method
+decode()supports copying foreign pixel data formats into the pixel
+cache according to the QuantumTypes. The method encode() supports
+copying the pixels in the cache to a foreign pixel representation
+according to the format specified by QuantumTypes.</p>
+<p>Setting a view using the Pixels class does not cause the number of
+references to the underlying image to be reduced to one. Therefore, in
+order to ensure that only the current generation of the image is
+modified, the Image's modifyImage() method should be invoked to reduce
+the reference count on the underlying image to one. If this is not
+done, then it is possible for a previous generation of the image to be
+modified due to the use of reference counting when copying or
+constructing an Image.</p>
+<p>The PixelPacket* returned by the set and get methods, and the
+IndexPacket* returned by the indexes method point to pixel data
+managed by the Pixels class. The Pixels class is responsible for
+releasing resources associated with the pixel view. This means that
+the pointer should never be passed to delete() or free().</p>

+<p>The pixel view is a small image in which the pixels may be accessed,
+addressed, and updated, as shown in the following example, which
+produces an image similar to the one on the right (minus lines and
+text):</p>

+image.type(TrueColorType);
+
+// Ensure that there is only one reference to underlying image
+// If this is not done, then image pixels will not be modified.
+image.modifyImage();
+
+// Allocate pixel view
+Pixels view(image);
+
+// Set all pixels in region anchored at 38x36, with size 160x230 to green.

+<p>The TypeMetric class provides the means to pass data from the Image
+class's TypeMetric method to the user. It provides information
+regarding font metrics such as ascent, descent, text width, text
+height, and maximum horizontal advance. The units of these font
+metrics are in pixels, and that the metrics are dependent on the
+current Image font (default Ghostscript's "Helvetica"), pointsize
+(default 12 points), and x/y resolution (default 72 DPI) settings.</p>
+<p>The pixel units may be converted to points (the standard
+resolution-independent measure used by the typesetting industry) via
+the following equation:</p>
+<pre class="literal-block">
+size_points = (size_pixels * 72)/resolution
+</pre>
+<p>where resolution is in dots-per-inch (DPI). This means that at the
+default image resolution, there is one pixel per point.</p>
+<p>Note that a font's pointsize is only a first-order approximation of
+the font height (ascender + descender) in points. The relationship
+between the specified pointsize and the rendered font height is
+determined by the font designer.</p>
+<p>See <a class="reference external" href="http://freetype.sourceforge.net/freetype2/docs/glyphs/index.html">FreeType Glyph Conventions</a>
+for a detailed description of font metrics related issues.</p>
+<p>The following is the definition of the Magick::TypeMetric class:</p>

+class MagickDLLDecl TypeMetric
+{
+ friend class Image;
+public:
+
+ TypeMetric ( void );
+ ~TypeMetric ( void );
+
+ // Ascent, the distance in pixels from the text baseline to the

+<p><em>Magick++</em> is the object-oriented C++ API to the <a class="reference external" href="../index.html">GraphicsMagick</a>
+image-processing library, the most comprehensive open-source image
+processing package available. Read the <a class="reference external" href="ChangeLog.html">ChangeLog</a> for <em>Magick++</em>.</p>
+<p><em>Magick++</em> supports an object model which is inspired by <a class="reference external" href="../perl.html">PerlMagick</a>.
+Images support implicit reference counting so that copy constructors and
+assignment incur almost no cost. The cost of actually copying an image
+(if necessary) is done just before modification and this copy is managed
+automatically by <em>Magick++</em>. De-referenced copies are automatically
+deleted. The image objects support value (rather than pointer) semantics
+so it is trivial to support multiple generations of an image in memory at
+one time.</p>
+<p><em>Magick++</em> provides integrated support for the <a class="reference external" href="http://www.sgi.com/tech/stl/">Standard Template
+Library</a> (<cite>STL</cite>) which is part of the standard C++ language so that
+the powerful containers available (e.g. <a class="reference external" href="http://www.sgi.com/tech/stl/Deque.html">deque</a>, <a class="reference external" href="http://www.sgi.com/tech/stl/Vector.html">vector</a>, <a class="reference external" href="http://www.sgi.com/tech/stl/List.html">list</a>, and
+<a class="reference external" href="http://www.sgi.com/tech/stl/Map.html">map</a>) can be used to write programs similar to those possible with
+PERL & <a class="reference external" href="../perl.html">PerlMagick</a>. STL-compatible template versions of
+GraphicsMagick's list-style operations are provided so that operations
+may be performed on multiple images stored in STL containers.</p>
+</div>
+<div class="section" id="api">
+<h1><a class="toc-backref" href="#id2">API</a></h1>
+<p><em>Magick++</em> provides a simple C++ API to the GraphicsMagick image
+processing library which supports reading and writing a huge number of
+image formats as well as supporting a broad spectrum of traditional image
+processing operations. The GraphicsMagick C API is complex and the data
+structures are not well documented. <em>Magick++</em> provides access to most of
+the features available from the C API but in a simple object-oriented and
+well-documented framework.</p>
+<p><em>Magick++</em> is intended to support commercial-grade application
+development. In order to avoid possible conflicts with the user's
+application, all symbols contained in <em>Magick++</em> (included by the header
+<Magick++.h>) are scoped to the namespace Magick. Symbols from the
+GraphicsMagick C library are imported under the MagickLib namespace to
+avoid possible conflicts and GraphicsMagick macros are only included
+within the <em>Magick++</em> implementation so they won't impact the user's
+application.</p>
+<p>The InitializeMagick() function <em>MUST</em> be invoked before constructing
+any Magick++ objects. This used to be optional, but now it is
+absolutely required. This function initalizes semaphores and
+configuration information necessary for the software to work
+correctly. Failing to invoke InitializeMagick() is likely to lead to
+a program crash or thrown assertion. If the program resides in the
+same directory as the GraphicsMagick files, then argv[0] may be passed
+as an argument so that GraphicsMagick knows where its files reside,
+otherwise NULL may be passed and GraphicsMagick will try to use other
+means (if necessary).</p>
+<p>The core class in <em>Magick++</em> is the <a class="reference external" href="Image.html">Image</a> class. The <a class="reference external" href="Image.html">Image</a> class
+provides methods to manipulate a single image frame (e.g. a JPEG image).
+Standard Template Library (<a class="reference external" href="STL.html">STL</a>) compatible algorithms and function
+objects are provided in order to manipulate multiple image frames or to
+read and write file formats which support multiple image frames (e.g. GIF
+animations, MPEG animations, and Postscript files).</p>
+<p>The <a class="reference external" href="Image.html">Image</a> class supports reference-counted memory management which
+supports the semantics of an intrinsic variable type (e.g. 'int') with an
+extremely efficient operator = and copy constructor (only a pointer is
+assigned) while ensuring that the image data is replicated as required so
+that it the image may be modified without impacting earlier generations.
+Since the <a class="reference external" href="Image.html">Image</a> class manages heap memory internally, images are best
+allocated via C++ automatic (stack-based) memory allocation. This support
+allows most programs using <em>Magick++</em> to be written without using any
+pointers, simplifying the implementation and avoiding the risks of using
+pointers. When a program uses automatic memory allocation to allocate
+<em>Magick++</em> images, that aspect of the program becomes naturally
+exception-safe and thread-safe.</p>
+<p>The image class uses a number of supportive classes in order to specify
+arguments. Colors are specified via the <a class="reference external" href="Color.html">Color</a> class. Colors specified
+in X11-style string form are implicitly converted to the <a class="reference external" href="Color.html">Color</a> class.
+Geometry arguments (those specifying width, height, and/or x and y
+offset) are specified via the <a class="reference external" href="Geometry.html">Geometry</a> class. Similar to the <a class="reference external" href="Color.html">Color</a>
+class, geometries specified as an X11-style string are implicitly
+converted to the <a class="reference external" href="Geometry.html">Geometry</a> class. Two dimensional drawable objects are
+specified via the <a class="reference external" href="Drawable.html">Drawable</a> class. Drawable objects may be provided as
+a single object or as a list of objects to be rendered using the current
+image options. <a class="reference external" href="Montage.html">Montage</a> options (a montage is a rendered grid of
+thumbnails in one image) are specified via the <a class="reference external" href="Montage.html">Montage</a> class.</p>
+<p>Errors are reported using C++ exceptions derived from the <a class="reference external" href="Exception.html">Exception</a>
+class, which is itself derived from the standard C++ exception class.
+Exceptions are reported synchronous with the operation and are caught by
+the first matching try block as the stack is unraveled. This allows a
+clean coding style in which multiple related <em>Magick++</em> commands may be
+executed with errors handled as a unit rather than line-by-line. Since
+the <a class="reference external" href="Image.html">Image</a> object provides reference-counted memory management,
+unreferenced images on the stack are automatically cleaned up, avoiding
+the potential for memory leaks.</p>

+classes is available via the following table:</p>

+<h1><a class="toc-backref" href="#id3">Obtaining Magick++</a></h1>
+<p><em>Magick++</em> is included as part of <a class="reference external" href="../index.html">GraphicsMagick</a> source releases and may
+be retrieved via <a class="reference external" href="../download.html">ftp</a> or <a class="reference external" href="../Hg.html">Mercurial</a>.</p>
+</div>
+<div class="section" id="installation">
+<h1><a class="toc-backref" href="#id4">Installation</a></h1>
+<p>Installation is very easy since <em>Magick++</em> is part of <a class="reference external" href="../index.html">GraphicsMagick</a> and
+is built by default. Once <a class="reference external" href="../index.html">GraphicsMagick</a> is built, then <em>Magick++</em> is
+available for use.</p>
+</div>
+<div class="section" id="usage">
+<h1><a class="toc-backref" href="#id5">Usage</a></h1>
+<p>A helper script named <em>GraphicsMagick++-config</em> is installed in the same
+directory as the GraphicsMagick <em>gm</em> program under Unix which assists
+with recalling compilation options required to compile and link programs
+which depend on <em>Magick++</em>. For example, the following command will
+compile and link the source file example.cpp to produce the executable
+example (notice that quotes are backward quotes):</p>
+<pre class="literal-block">
+c++ -o example example.cpp `GraphicsMagick++-config --cppflags --cxxflags
+ --ldflags --libs`
+</pre>
+<p>Windows users may get started by manually editing a project file for one
+of the <em>Magick++</em> demo programs.</p>
+<p>It is necessary to initialize the GraphicsMagick library prior to
+using the <em>Magick++</em> library. This initialization is performed by
+passing the path to the GraphicsMagick DLLs (assumed to be in the same
+directory as your program) to the InitializeMagick() function
+call. This is commonly performed by providing the path to your program
+(argv[0]) as shown in the following example:</p>
+<pre class="literal-block">
+int main( int /*argc*/, char ** argv)
+{
+ InitializeMagick(*argv);
+</pre>
+<p>If you don't have the path to your executable, then pass NULL and
+usually the library will be found anyway. Besides helping to find the
+GraphicsMagick DLL/library and configuration files, InitializeMagick()
+initializes all of the semaphores and data necessary for a
+multi-threaded program to be completely thread safe. This step used
+to be optional, but it is now absolutely required. Failure to
+initialize GraphicsMagick will result in an application crash.</p>

+<p>Special Issues:</p>
+<ul class="simple">
+<li>None</li>
+</ul>
+<p>Security Fixes:</p>
+<ul class="simple">
+<li>GraphicsMagick is participating in Google's oss-fuzz project due to
+the contributions and assistance of Alex Gaynor. Since February 4
+2018, 454 issues have been opened by oss-fuzz (some of which were
+benign build issues such as SourceForge Mercurial not working
+correctly) and 7 issues remain open (all of which are marked in an
+"unreproducible" state). The issues list is available at
+<a class="reference external" href="https://bugs.chromium.org/p/oss-fuzz/issues/list">https://bugs.chromium.org/p/oss-fuzz/issues/list</a> under search term
+"graphicsmagick". Issues are available for anyone to view and
+duplicate if they have been in "Verified" status for 30 days, or if
+they have been in "New" status for 90 days. Please consult the
+GraphicsMagick ChangeLog file, Mercurial repository commit log, and
+the oss-fuzz issues list for details.</li>
+<li>WPG: Fixes for heap buffer overflow.</li>
+</ul>
+<p>Bug fixes:</p>
+<ul class="simple">
+<li>ConstituteImage(): Set image depth appropriately based on the
+storage size specified by StorageType and QuantumDepth.</li>
+<li>GetImageBoundingBox(): Fix problem that MagickTrimImage with extreme
+fuzz values could produce an image with negative width.</li>
+<li>ImageToFile(): Improve error handling to avoid possible deferred
+deletion of temporary files, causing unexpected excessive use of
+temporary file space.</li>
+<li>JNG: Add validations for alpha compression method values and use
+this information to enforce decoding using the appropriate
+sub-format (rather than auto-detecting the format). Also, address
+memory leaks which may occur if the sub-decoder does something other
+than was expected.</li>
+<li>MagickCondSignal(): Improvements to conditional signal handler
+registration (which avoids over-riding signal handlers previously
+registered by an API user).</li>
+<li>ModifyCache(): Fix memory leak.</li>
+<li>ReadCacheIndexes(): Don't blunder into accessing a null pointer if
+the using code has ignored a previous error report bubled-up from
+SetNexus().</li>
+<li>MNG: When doing image scaling and the image width or height is 1
+then always use simple pixel replication as per the MNG
+specification.</li>
+<li>MVG: Fixes to 'push clip-path foo' and 'pop clip-path foo' parsing
+to eliminate a class of malign behavior.</li>
+<li>MVG: Place an aribrary limit on stroke dash polygon unit maximum
+length in order to avoid possibly rendering "forever".</li>
+<li>PCL: No longer attempt to handle reading HP PCL format via the
+external 'hp2xx' program since it seems worthless for that task.</li>
+<li>PS: Fix corrupt image when writing PseudoClass image with a colormap
+larger than two entries as bilevel.</li>
+<li>SVG: Memory leak fixes.</li>
+<li>SVG reader: Now support 'ping' support so the identify command works
+as expected.</li>
+<li>TIFF: WEBP compression only supports a depth of 8 so force that
+value.</li>
+<li>Wand MagickSetSamplingFactors(): Correct formatting of sampling
+factors string.</li>
+</ul>
+<p>New Features:</p>
+<ul class="simple">
+<li>Logging is now fully programmable.</li>
+<li>DPX format: Support dpx:swap-samples-read define which behaves
+similar to dpx:swap-samples, but is only applied when reading, as
+well as dpx:swap-samples-write, which is only applied when
+writing. This provides for use when there is both reading and
+writing in the same operation (otherwise the final result was no
+effect!).</li>
+</ul>
+<p>API Updates:</p>
+<ul class="simple">
+<li>magick/api.h: Add "magick/enum_strings.h" to API headers.</li>
+<li>New log settings accessor C functions: SetLogDefaultFileName(),
+SetLogDefaultFormat(), SetLogDefaultOutputType(),
+SetLogDefaultLogMethod(), SetLogDefaultLimit(),
+SetLogDefaultGenerations(), SetLogDefaultEventType(). These
+functions allow a program to set the same parameters which may be
+set by loading a "log.mgk" function. If a default logging callback
+was provided via SetLogDefaultLogMethod() such that MethodOutput is
+used, then the search for a "log.mgk" is avoided entirely.</li>
+<li>New log settings accessor C++ functions: SetLogDefaultFileName(),
+SetLogDefaultFormat(), SetLogDefaultOutputType(),
+SetLogDefaultLogMethod(), SetLogDefaultLimit(),
+SetLogDefaultGenerations(), SetLogDefaultEventType(). These C++
+functions just pass through to the equivalent C functions and
+provide the same benefits.</li>
+</ul>
+<p>Feature improvements:</p>
+<ul class="simple">
+<li>A simple resource-limit respecting memory allocator has been
+developed for internal use wherever arbitrarily-large amounts of
+memory might be requested. This will gradually be added wherever it
+appears to be needed. The memory resource limits are at the overall
+process level. The MVG/SVG rendering code is updated to use this
+new allocator. Almost all of the coders (image format
+readers/writers) have now been updated to use this new allocator.
+This means that '-limit memory 300MB' would be more complete and
+meaningful now. Temporary allocations by the image processing
+algorithms (other than for the images themselves) are still not
+accounted for in the resource limiting.</li>
+<li>MVG Renderer / DrawImage(): Use resource-limit respecting memory
+allocators for remaining large memory allocations.</li>
+<li>PNG writer: Don't skip optional Exif identifier code if it isn't present.</li>
+<li>DPX reader/writer: decode/encode of 10-bit packed DPX is now twice
+as fast due to code simplification.</li>
+<li>TIFF reader: Apply the same resource limits to TIFF tile sizes as
+apply to the image itself.</li>
+</ul>
+<p>Windows Delegate Updates/Additions:</p>
+<ul class="simple">
+<li>None</li>
+</ul>
+<p>Build Changes:</p>
+<ul class="simple">
+<li>configure.ac: Update syntax to avoid using deprecated syntax
+according to Autoconf 2.69. Also added copious m4 quoting.</li>
+<li>Magick++ Drawable base class no longer uses std::unary_function when
+compiled using C++'17 or later, since this feature has been removed
+from the language.</li>
+<li>Support the configure option --disable-compressed-files to disable
+automatic decompress of gzip and bzip2 compressed files (e.g. files
+with extension 'gz' or 'bz2', and sometimes 'svgz', but sometimes
+posing as some other format). It turns out that there are some
+extremely compressed files (e.g. over 1000x compression ratio) which
+can take a long time to decompress and produce large temporary
+files. We currently normally wait for the whole file to be
+decompressed before decoding it. The only exception is for coders
+with native 'blob' support and which do not require seeking, and
+that the user forced forced the format by adding a magick prefix
+like "DPX:file.dpx" to avoid the automatic file format detection.</li>
+<li>Support the configure option --without-gs to disable reading PS,
+EPS, and PDF formats via an external Ghostscript delegate program.
+This corresponds to the HasGS definition in the source code.</li>
+<li>Support the configure option --without-gdi32 to support disabling
+use of the Microsoft Windows gdi32 library if it is not wanted.</li>
+<li>The Automake-based test suite now applies a memory limit of 128MB
+for the Q8, or 256MB for the Q16, or 512MB for the Q32 build, as
+well as setting a disk space limit of 0. The limits place an upper
+bound on the resources required, while assuring that tests do pass
+with resource limits applied, while also assuring that disk-based
+pixel-cache files are not used.</li>
+</ul>
+<p>Behavior Changes:</p>
+<ul class="simple">
+<li>Previously the formatting settings from "log.mgk" were only used
+when writing to a file, or to the console, via a file handle. Now
+the log formatting has been normalized so that the settings provided
+by "log.mgk" (or SetLogDefaultFormat()) will always be used. It is
+possible this may result in some formatting changes.</li>
+<li>In the Windows Visual Studio build, the ProvideDllMain option is now
+disabled by default (can still be enabled) since it causes
+InitializeMagick() to be invoked prior to when the program's main()
+routine is called, thereby blocking configuration activities or use
+of InitializeMagickEx(). With this change it is even more
+imperative that InitializeMagick() be explicitly invoked by all
+programs using GraphicsMagick.</li>

+<h1><a class="toc-backref" href="#id1">Overview</a></h1>
+<p>GraphicsMagick has been transformed to use <a class="reference external" href="http://openmp.org/">OpenMP</a> for the 1.3 release
+series. OpenMP is a portable framework for accelerating CPU-bound and
+memory-bound operations using multiple threads. OpenMP originates in
+the super-computing world and has been available in one form or
+another since the late '90s.</p>
+<p>Since GCC 4.2 has introduced excellent OpenMP support via <a class="reference external" href="http://gcc.gnu.org/onlinedocs/libgomp/">GOMP</a>,
+OpenMP has become available to the masses. Recently, <a class="reference external" href="https://clang.llvm.org/">Clang</a> has
+also implemented good OpenMP support. Microsoft Visual Studio
+Professional 2005 and later support OpenMP so Windows users can
+benefit as well. Any multi-CPU and/or multi-core system is potentially
+a good candidate for use with OpenMP. Modern multi-core chipsets from
+AMD, Intel, IBM, Oracle, and ARM perform very well with OpenMP.</p>
+<p>Most image processing routines are comprised of loops which iterate
+through the image pixels, image rows, or image regions. These loops
+are accelerated using OpenMP by executing portions of the total loops
+in different threads, and therefore on a different processor
+core. CPU-bound algorithms benefit most from OpenMP, but memory-bound
+algorithms may also benefit as well since the memory is accessed by
+different CPU cores, and sometimes the CPUs have their own path to
+memory. For example, the AMD Opteron is a <a class="reference external" href="https://en.wikipedia.org/wiki/Non-uniform_memory_access">NUMA</a> (Non-Uniform Memory
+Architecture) design such that multi-CPU systems split the system
+memory across CPUs so each CPU adds more memory bandwidth as well.
+Server-class CPUs offer more independent memory channels than desktop
+CPUs do.</p>
+<p>For severely CPU-bound algorithms, it is not uncommon to see a linear
+speed-up (within the constraints of <a class="reference external" href="https://en.wikipedia.org/wiki/Amdahl%27s_law">Amdahl's law</a>) due to the number
+of cores. For example, a two core system executes the algorithm twice
+as fast, and a four core system executes the algorithm four times as
+fast. Memory-bound algorithms scale based on the memory bandwith
+available to the cores. For example, memory-bound algorithms scale up
+to almost 1.5X on my four core Opteron system due to its <a class="reference external" href="https://en.wikipedia.org/wiki/Non-uniform_memory_access">NUMA</a>
+architecture. Some systems/CPUs are able to immediately context switch
+to another thread if the core would be blocked waiting for memory,
+allowing multiple memory accesses to be pending at once, and thereby
+improving throughput. For example, typical speedup of 20-32X (average
+24X) has been observed on the Sun SPARC T2 CPU, which provides 8
+cores, with 8 virtual CPUs per core (64 threads).</p>
+<p>An approach used in GraphicsMagick is to recognize the various access
+patterns in the existing code, and re-write the algorithms (sometimes
+from scratch) to be based on a framework that we call "pixel iterators".
+With this approach, the computation is restricted to a small unit (a
+callback function) with very well defined properties, and no knowledge as
+to how it is executed or where the data comes from. This approach removes
+the loops from the code and puts the loops in the framework, which may be
+adjusted based on experience. The continuing strategy will be to
+recognize design patterns and build frameworks which support those
+patterns. Sometimes algorithms are special/exotic enough that it is much
+easier to instrument the code for OpenMP rather than to attempt to fit
+the algorithm into a framework.</p>
+<p>Since OpenMP is based on multi-threading, multiple threads access the
+underlying pixel storage at once. The interface to this underlying
+storage is called the "pixel cache". The original pixel cache code
+(derived from ImageMagick) was thread safe only to the extent that it
+allowed one thread per image. This code has now been re-written so that
+multiple threads may safely and efficiently work on the pixels in one
+image. The re-write also makes the pixel cache thread safe if a
+multi-threaded application uses an OpenMP-fortified library.</p>
+<p>GraphicsMagick provides its own built-in 'benchmark' driver utility
+which may be used to execute a multi-threaded benchmark of any other
+utility command.</p>
+<p>Using the built-in 'benchmark' driver utility, the following is an
+example of per-core speed-up due to OpenMP on a four-core AMD Opteron
+system (with Firefox and other desktop software still running). The
+image is generated dynamically based on the 'granite' pattern and all
+the pixel quantum values have 30% gaussian noise added:</p>
+<pre class="literal-block">
+% gm benchmark -stepthreads 1 -duration 10 convert \
+ -size 2048x1080 pattern:granite -operator all Noise-Gaussian 30% null:
+Results: 1 threads 5 iter 11.34s user 11.340000s total 0.441 iter/s 0.441 iter/cpu 1.00 speedup 1.000 karp-flatt
+Results: 2 threads 9 iter 20.34s user 10.190000s total 0.883 iter/s 0.442 iter/cpu 2.00 speedup 0.000 karp-flatt
+Results: 3 threads 14 iter 31.72s user 10.600000s total 1.321 iter/s 0.441 iter/cpu 3.00 speedup 0.001 karp-flatt
+Results: 4 threads 18 iter 40.84s user 10.460000s total 1.721 iter/s 0.441 iter/cpu 3.90 speedup 0.008 karp-flatt
+</pre>
+<p>Note that the "iter/s cpu" value is a measure of the number of
+iterations given the amount of reported CPU time consumed. It is an
+effective measure of relative efficacy since its value should ideally
+not drop as iterations are added. The <a class="reference external" href="https://en.wikipedia.org/wiki/Karp%E2%80%93Flatt_metric">karp-flatt metric</a> is another
+useful metric for evaluating thread-speedup efficiency. In the above
+example, the total speedup was about 3.9X with only a slight loss of
+CPU efficiency as threads are added.</p>
+</div>
+<div class="section" id="limitations">
+<h1><a class="toc-backref" href="#id2">Limitations</a></h1>
+<p>Often it is noticed that the memory allocation functions (e.g. from
+the standard C library such as GNU libc) significantly hinder
+performance since they are designed or optimized for single-threaded
+programs, or prioritize returning memory to the system over speed.
+Memory allocators are usually designed and optimized for programs
+which perform thousands of small allocations, and if they make a large
+memory allocation, they retain that memory for a long time.
+GraphicsMagick performs large memory allocations for raster image
+storage interspersed with a limited number of smaller allocations for
+supportive data structures. This memory is released very quickly
+since GraphicsMagick is highly optimized and thus the time between
+allocation and deallocation can be very short. It has been observed
+that some memory allocators are much slower to allocate and deallocate
+large amounts of memory (e.g. a hundred megabytes) than alternative
+allocators, even in single-threaded programs. Under these conditions,
+the program can spend considerable time mysteriously "sleeping".</p>
+<p>In order to help surmount problems with the default memory allocators,
+the configure script offers support for use of Google <a class="reference external" href="https://github.com/gperftools/gperftools">gperftools</a> <a class="reference external" href="https://github.com/gperftools/gperftools/wiki">'tcmalloc'</a>, Solaris mtmalloc,
+and Solaris umem libraries via the --with-tcmalloc, --with-mtmalloc,
+and --with-umem options, respectively. When the allocation functions
+are behaving badly, the memory allocation/deallocation performance
+does not scale as threads are added and thus additional threads spend
+more time sleeping (e.g. on a lock, or in munmap()) rather than doing
+more work. Performance improvements of a factor of two are not
+uncommon even before contending with the hugh CPU core/thread counts
+available on modern CPUs. Using more threads which are slowed by
+poorly-matched memory allocation functions is wasteful of memory,
+system resources, human patience, and electrical power.</p>
+<p>Many modern CPUs support "Turbo" modes where the CPU clock rate is
+boosted if only a few cores are active. When a CPU provides a "Turbo"
+mode, this decreases the apparent speed-up compared to using one
+thread because the one thread was executed at a much higher clock
+rate. Likewise, when a CPU becomes very hot (due to being heavily
+used), it may decrease its clock rates overall to avoid burning up,
+and this may also decreases the actual speed-up when using many
+threads compared to using one thread. Many CPUs support
+"hyperthreads" or other mechanisms in which one physical core will
+support multiple light-weight threads, and if the core is efficiently
+used by one thread, then this will decrease the apparent per-thread
+speed-up but the peak speed-up will hopefully still be bounded by the
+number of physical cores.</p>
+<p>In most cases, OpenMP does not speed-up loading an image from a file,
+or writing an image to a file. It is common for file decode and
+encode to take longer than processing the image. Using uncompressed
+formats is recommended with a fast I/O subsystem (or in-memory 'blobs'
+in order to obtain the greated speed-up from OpenMP.</p>
+<p>It has been observed that sometimes it takes much longer to start and
+stop GraphicsMagick than it takes for it to run the requested
+algorithm. The slowness is due to inefficiencies of the libraries
+that GraphicsMagick is linked with (especially the ICU library that
+libxml2 is often linked with). If GraphicsMagick takes too long to
+perform trivial operations, then consider using the 'modules' build,
+and investigate the 'batch' utility which allows running many
+GraphicsMagick commands as a 'batch' script. If a 'modules' build is
+not feasible, then configuring GraphicsMagick to only support the
+specific formats actually needed can help with its execution time and
+improve opportunity for OpenMP speed-up.</p>

+<div class="section" id="openmp-variables">
+<h1><a class="toc-backref" href="#id3">OpenMP Variables</a></h1>
+<p>According to the OpenMP specification, the OMP_NUM_THREADS evironment
+variable may be used to specify the number of threads available to the
+application. Typically this is set to the number of processor cores on
+the system but may be set lower to limit resource consumption or (in
+some cases) to improve execution efficiency. The GraphicsMagick
+commands also accept a <tt class="docutils literal"><span class="pre">-limit</span> threads limit</tt> type option for

+<p>The GraphicsMagick core C library constitutes the implementation of
+GraphicsMagick and provides the lowest-level C language programming
+interface for GraphicsMagick. The core C API provides many functions
+to read, manipulate, write, or display an image. To invoke the
+functions, write your program in C (or C++) language while making
+calls to the core library functions and link with libGraphicsMagick.a,
+libGraphicsMagick.so, or GraphicsMagick.dll depending on your system.</p>
+<p>The API is divided into a number of categories. While reading this
+documentation, please reference the <a class="reference external" href="types.html">types</a> documentation as required:</p>

+<h2>Description</h2>
+<p>The CdlImage() method applies ("bakes in") the ASC-CDL which is a format
+for the exchange of basic primary color grading information between
+equipment and software from different manufacturers. The format defines
+the math for three functions: slope, offset and power. Each function uses
+a number for the red, green, and blue color channels for a total of nine
+numbers comprising a single color decision. A tenth number for chrominance
+(saturation) has been proposed but is not yet standardized.</p>
+<p>The cdl argument string is comma delimited and is in the form (but
+without invervening spaces or line breaks):</p>
+<p>redslope, redoffset, redpower :
+greenslope, greenoffset, greenpower :
+blueslope, blueoffset, bluepower :
+saturation</p>
+<p>with the unity (no change) specification being:</p>
+<p>"1.0,0.0,1.0:1.0,0.0,1.0:1.0,0.0,1.0:0.0"</p>
+<p>See <a class="reference external" href="http://en.wikipedia.org/wiki/ASC_CDL">http://en.wikipedia.org/wiki/ASC_CDL</a> for more information.</p>

+<h2>Description</h2>
+<p>IsImagesEqual() measures the difference between colors at each pixel
+location of two images. A value other than 0 means the colors match
+exactly. Otherwise an error measure is computed by summing over all
+pixels in an image the distance squared in RGB space between each image
+pixel and its corresponding pixel in the reference image. The error
+measure is assigned to these image members:</p>
+<p>o mean_error_per_pixel: The mean error for any single pixel in
+the image.</p>
+<p>o normalized_mean_error: The normalized mean quantization error for
+any single pixel in the image. This distance measure is normalized to
+a range between 0 and 1. It is independent of the range of red, green,
+and blue values in the image.</p>
+<p>o normalized_maximum_error: The normalized maximum quantization
+error for any single pixel in the image. This distance measure is
+normalized to a range between 0 and 1. It is independent of the range
+of red, green, and blue values in your image.</p>
+<p>A small normalized mean square error, accessed as
+image->normalized_mean_error, suggests the images are very similiar in
+spatial layout and color.</p>

+<h2>Description</h2>
+<p>ConstituteImage() returns an Image corresponding to an image stored
+in a raw memory array format. The pixel data must be in scanline order
+top-to-bottom. The data can be unsigned char, unsigned short int, unsigned
+int, unsigned long, float, or double. Float and double require the pixels
+to be normalized to the range [0..1], otherwise the range is [0..MaxVal]
+where MaxVal is the maximum possible value for that type.</p>
+<p>Note that for most 32-bit architectures the size of an unsigned long is
+the same as unsigned int, but for 64-bit architectures observing the LP64
+standard, an unsigned long is 64 bits, while an unsigned int remains 32
+bits. This should be considered when deciding if the data should be
+described as "Integer" or "Long".</p>

+<h2>Description</h2>
+<p>The HaldClutImage() method apply a color lookup table (Hald CLUT) to the
+image. The fundamental principle of the Hald CLUT algorithm is that
+application of an identity CLUT causes no change to the input image,
+but an identity CLUT image which has had its colors transformed in
+some way (e.g. in Adobe Photoshop) may be used to implement an identical
+transform on any other image.</p>
+<p>The minimum CLUT level is 2, and the maximum depends on available memory
+(largest successfully tested is 24). A CLUT image is required to have equal
+width and height. A CLUT of level 8 is an image of dimension 512x512, a CLUT
+of level 16 is an image of dimension 4096x4096. Interpolation is used so
+extremely large CLUT images are not required.</p>
+<p>GraphicsMagick provides an 'identity' coder which may be used to generate
+identity HLUTs. For example, reading from "identity:8" creates an identity
+CLUT of order 8.</p>
+<p>The Hald CLUT algorithm has been developed by Eskil Steenberg as described
+at <a class="reference external" href="http://www.quelsolaar.com/technology/clut.html">http://www.quelsolaar.com/technology/clut.html</a>, and was adapted for
+GraphicsMagick by Clément Follet with support from Cédric Lejeune of
+Workflowers.</p>
+<p>The format of the HaldClutImage method is:</p>
+<pre class="literal-block">
+MagickPassFail HaldClutImage( <a class="reference external" href="../api/types.html#image">Image</a> *image, const <a class="reference external" href="../api/types.html#image">Image</a> *clut );

<p>AllocateImage() returns a pointer to an image structure initialized to

+default values. Currently a failure in this function results in a fatal
+error, resulting in program exit.</p>
<p>The format of the AllocateImage method is:</p>
<pre class="literal-block">
<a class="reference external" href="../api/types.html#image">Image</a> *AllocateImage( const <a class="reference external" href="../api/types.html#imageinfo">ImageInfo</a> *image_info );
<p>Use AllocateNextImage() to initialize the next image in a sequence to
default values. The next member of image points to the newly allocated
image. If there is a memory shortage, next is assigned NULL.</p>
+<p>It is expected that the image next pointer is null, since otherwise
+there is likely to be a memory leak. In the future this may be enforced.</p>
<p>The format of the AllocateNextImage method is:</p>
<pre class="literal-block">
void AllocateNextImage( const <a class="reference external" href="../api/types.html#imageinfo">ImageInfo</a> *image_info, <a class="reference external" href="../api/types.html#image">Image</a> *image );
<p>DestroyImage() dereferences an image, deallocating memory associated with
the image if the reference count becomes zero. There is no effect if the
image pointer is null.</p>
+<p>In the interest of avoiding dangling pointers or memory leaks, the image
+previous and next pointers should be null when this function is called,
+and no other image should refer to it. In the future this may be enforced.</p>
<p>The format of the DestroyImage method is:</p>

+<h2>Description</h2>
+<p>ImportViewPixelArea() transfers one or more pixel components from a user
+supplied buffer into the specified image pixel cache view of an image. By
+default, values are read in network (big-endian) byte/bit order. By
+setting the 'endian' member of ExportPixelAreaOptions, 16, 32 and 64-bit
+values may be output as little (LSBEndian), big (MSBEndian), or host
+native (NativeEndian) endian values. This function is quite powerful in
+that besides common native CPU type sizes, it can support any integer bit
+depth from 1 to 32 (e.g. 13), 64-bits, as well as 32 and 64-bit float.</p>
+<p>MagickPass is returned if the pixels are successfully transferred,
+otherwise MagickFail.</p>

+<p>MagickMonitorFormatted() calls the monitor handler method with a

+<h2>Description</h2>
+<p>Method SegmentImage segment an image by analyzing the histograms of the
+color components and identifying units that are homogeneous with the fuzzy
+c-means technique.</p>
+<p>Specify cluster threshold as the number of pixels in each cluster must
+exceed the the cluster threshold to be considered valid. Smoothing
+threshold eliminates noise in the second derivative of the histogram.
+As the value is increased, you can expect a smoother second derivative.

+<h1><a class="toc-backref" href="#id24">Image</a></h1>
+<p>The Image structure represents an GraphicsMagick image. It is initially
+allocated by AllocateImage() and deallocated by DestroyImage(). The
+functions ReadImage(), ReadImages(), BlobToImage() and CreateImage()
+return a new image. Use CloneImage() to copy an image. An image consists
+of a structure containing image attributes as well as the image pixels.</p>
+<p>The image pixels are represented by the structure PixelPacket and are
+cached in-memory, or on disk, depending on the cache threshold setting.
+This cache is known as the "pixel cache". Pixels in the cache may not be
+edited directly. They must first be made visible from the cache via a
+pixel view. A pixel view is a rectangular view of the pixels as defined
+by a starting coordinate, and a number of rows and columns. When
+considering the varying abilities of multiple platforms, the most
+reliably efficient pixel view is comprized of part, or all, of one image
+row.</p>
+<p>There are two means of accessing pixel views. When using the default
+view, the pixels are made visible and accessable by using the
+GetImagePixels() method which provides access to a specified region of
+the image. After the view has been updated, the pixels may be saved back
+to the cache in their original positions via SyncImagePixels(). In order
+to create an image with new contents, or to blindly overwrite existing
+contents, the method SetImagePixels() is used to reserve a pixel view
+corresponding to a region in the pixel cache. Once the pixel view has
+been updated, it may be written to the cache via SyncImagePixels(). The
+function GetIndexes() provides access to the image colormap, represented
+as an array of type IndexPacket.</p>
+<p>A more flexible interface to the image pixels is via the Cache View
+interface. This interface supports multiple pixel cache views (limited by
+the amount of available memory), each of which are identified by a handle
+(of type ViewInfo). Use OpenCacheView() to obtain a new cache view,
+CloseCacheView() to discard a cache view, GetCacheViewPixels() to access
+an existing pixel region, SetCacheView() to define a new pixel region,
+and SyncCacheViewPixels() to save the updated pixel region. The function
+GetCacheViewIndexes() provides access to the colormap indexes associated
+with the pixel view.</p>
+<p>When writing encoders and decoders for new image formats, it is
+convenient to have a high-level interface available which supports
+converting between external pixel representations and GraphicsMagick's
+own representation. Pixel components (red, green, blue, opacity, RGB, or
+RGBA) may be transferred from a user-supplied buffer into the default
+view by using ImportImagePixelArea(), or from an allocated view via
+ImportViewPixelArea(). Pixel components may be transferred from the
+default view into a user-supplied buffer by using ExportImagePixelArea(),
+or from an allocated view via ExportViewPixelArea(). Use of this
+high-level interface helps protect image coders from changes to
+GraphicsMagick's pixel representation and simplifies the implementation.</p>

+<h1><a class="toc-backref" href="#id30">MagickInfo</a></h1>
+<p>The MagickInfo structure is used by GraphicsMagick to register support
+for an image format. The MagickInfo structure is allocated with default
+parameters by calling SetMagickInfo(). Image formats are registered by
+calling RegisterMagickInfo() which adds the initial structure to a linked
+list (at which point it is owned by the list). A pointer to the structure
+describing a format may be obtained by calling GetMagickInfo(). Pass the
+argument NULL to obtain the first member of this list. A human-readable
+list of registered image formats may be printed to a file descriptor by
+calling ListMagickInfo().</p>
+<p>Support for formats may be provided as a module which is part of the
+GraphicsMagick library, provided by a module which is loaded dynamically
+at run-time, or directly by the linked program. Users of GraphicsMagick
+will normally want to create a loadable-module, or support encode/decode
+of an image format directly from within their program.</p>
+<p>Sample Module:</p>
+<p>The following shows sample code for a module called "GIF" (gif.c). Note
+that the names of the Register and Unregister call-back routines are
+calculated at run-time, and therefore must follow the rigid naming scheme
+RegisterFORMATImage and UnregisterFORMATImage, respectively, where FORMAT
+is the upper-cased name of the module file:</p>
+<pre class="literal-block">
+/* Read image */
+Image *ReadGIFImage(const ImageInfo *image_info)
+{
+ [ decode the image ... ]
+}
+
+/* Write image */
+unsigned int WriteGIFImage(const ImageInfo *image_info,Image *image)
+{
+ [ encode the image ... ]
+}
+
+/* Module call-back to register support for formats */
+void RegisterGIFImage(void)
+{
+ MagickInfo *entry;
+ entry=SetMagickInfo("GIF");
+ entry->decoder=ReadGIFImage;
+ entry->encoder=WriteGIFImage;
+ entry->description="CompuServe graphics interchange format";
+ entry->module="GIF";
+ RegisterMagickInfo(entry);
+
+ entry=SetMagickInfo("GIF87");
+ entry->decoder=ReadGIFImage;
+ entry->encoder=WriteGIFImage;
+ entry->adjoin=False;
+ entry->description="CompuServe graphics interchange format (version 87a)";
+ entry->module="GIF";
+ RegisterMagickInfo(entry);
+}
+
+/* Module call-back to unregister support for formats */
+Export void UnregisterGIFImage(void)
+{
+ UnregisterMagickInfo("GIF");
+ UnregisterMagickInfo("GIF87");
+}
+</pre>
+<p>Sample Application Code</p>
+<p>Image format support provided within the user's application does not need
+to implement the RegisterFORMATImage and UnregisterFORMATImage call-back
+routines. Instead, the application takes responsibility for the
+registration itself. An example follows:</p>
+<pre class="literal-block">
+/* Read image */
+Image *ReadGIFImage(const ImageInfo *image_info)
+{
+ [ decode the image ... ]
+}
+/* Write image */
+unsigned int WriteGIFImage(const ImageInfo *image_info,Image *image)
+{
+ [ encode the image ... ]
+}
+#include <stdio.h>
+int main( void )
+{
+ struct MagickInfo* info;
+ info = SetMagickInfo("GIF");
+ if ( info == (MagickInfo*)NULL )
+ exit(1);
+ info->decoder = ReadGIFImage;
+ info->encoder = WriteGIFImage;
+ info->adjoin = False;
+ info->description = "CompuServe graphics interchange format";
+ /* Add MagickInfo structure to list */
+ RegisterMagickInfo(info);
+ info = GetMagickInfo("GIF");
+ [ do something with info ... ]
+ ListMagickInfo( stdout );

+<h1><a class="toc-backref" href="#id1">Foreword</a></h1>
+<p>This page used to document benchmark results which compared
+GraphicsMagick 1.3.8 performance to ImageMagick 6.5.8-10 performance.
+We found that GraphicsMagick was usually considerably faster at
+executing image processing operations from the command line than
+ImageMagick 6.5.8-10 was. One ImageMagick algorithm ran as much as 770
+times slower. GraphicsMagick clearly ran much more efficiently under
+Microsoft Windows.</p>
+<p>We now find that a simple head to head performance comparison between
+GraphicsMagick and recent ImageMagick is no longer possible because
+ImageMagick has changed the meanings of the existing arguments. In
+particular, we discovered that ImageMagick filter arguments producing
+convolution matrices are now producing lower-order convolution
+matrices representing perhaps an order of magnitude less work given
+the same arguments. The resulting images are visually substantially
+less filtered. Using the same command-line filter arguments causes
+GraphicsMagick to appear slower when it is actually doing far more
+work than ImageMagick.</p>
+<p>Due to it not being feasable to do a head to head performance
+measurement between GraphicsMagick and ImageMagick, we have decided to
+not post results at the moment. However, the strategy and a simple
+benchmark driver script are still provided for those who want to do
+their own performance comparisons between GraphicsMagick and
+ImageMagick.</p>
+</div>
+<div class="section" id="strategy">
+<h1><a class="toc-backref" href="#id2">Strategy</a></h1>
+<p>The benchmark focuses on the ability to process many medium sized
+HD-resolution (1920x1080 pixels) images. In order to prevent disk I/O
+from being a factor, we use a small input image and tile it to create
+a larger input image via the "tile:" coder. The processed image is
+sent to the "null:" coder so that file writes to a slow disk are also
+not a factor. Static executables are used and executed via full paths
+in order to minimize variability from the execution environment. In
+order to obtain accurate and useful timing, we use the bash shell to
+execute the command 40 times and see how long it takes. This is a very
+simple benchmark approach which is quite representative of the
+performance that the typical user observes.</p>
+<p>This new benchmark reveals the following performance criteria:</p>
+<blockquote>
+<ul class="simple">
+<li>Basic execution overhead of the software.</li>
+<li>Image processing algorithmic efficiency.</li>
+<li>Efficacy of OpenMP enhancements.</li>
+</ul>
+</blockquote>
+</div>
+<div class="section" id="the-benchmark">
+<h1><a class="toc-backref" href="#id3">The Benchmark</a></h1>
+<p>The benchmark is quite simple. It reads a list of commands to execute
+from a file named "commands.txt" and times how long it takes to
+execute each command 40 times using GraphicsMagick and ImageMagick.</p>
+<p>Here is the simple benchmark script:</p>
+<pre class="literal-block">

+<blockquote>
+<ul class="simple">
+<li>BMP reader is not working for some obscure low-color packed files.</li>
+<li>DPX reader/writer does not properly handle subformats where row
+samples spill over the storage word boundary. This means that
+single-channel/grayscale 10-bit DPX files will only work for widths
+evenly divisible by three. (SF 1533184)</li>
+<li>The PSD reader is disabled by default because it does not work well
+enough and several man-years worth of dedicated volunteer time is
+required to make it work properly.</li>
+<li>Scitex reader is not working for some files.</li>
+<li>SVG writer works only if you are particularly luckly and so it is
+not included in the build by default..</li>
+<li>SVG reader mishandles basic units and many other syntax elements (SF

+<!-- See http://docutils.sourceforge.net/rst.html for details. -->
+<p>The future and success of GraphicsMagick depends on your contributions.
+By contributing to GraphicsMagick you will benefit from the
+features/fixes you contribute, can take pride in taking part in the
+development of a quality product, and you can tell your friends that you
+contribute to the GraphicsMagick project.</p>
+<p>There are a number of ways you can contribute:</p>
+<ul class="simple">
+<li>Submit bug reports to the GraphicsMagick bug tracking system at
+SourceForge.</li>
+<li>Submit patches to the GraphicsMagick patch submission system at
+SourceForge.</li>
+<li>Perform test builds on unusual systems and report the results.</li>
+<li>Submit ideas and proposed designs to the graphicsmagick-core
+mailing list.</li>
+<li>Create a new language interface, dependent library, or application.</li>
+<li>Join the GraphicsMagick Group as a full-fledged developer with CVS
+commit access.</li>
+</ul>
+<p>Regardless of how you choose to contribute, your contributions will be
+treated with the respect and value that they deserve.</p>
+<p>Becoming a member of the GraphicsMagick Group requires a majority vote
+from existing members. Your chances of being admitted to the group are
+increased significantly if you have a proven track-record of success on
+other open source projects, are a recognized expert in the field, or have
+already demonstrated your capabilities and commitment by contributing to
+the project in other ways. Please contact Bob Friesenhahn
+<<a class="reference external" href="mailto:bfriesen%40simple.dallas.tx.us">bfriesen<span>@</span>simple<span>.</span>dallas<span>.</span>tx<span>.</span>us</a>> in order to be considered for group
+membership.</p>
+<div class="section" id="areas-to-contribute">
+<h1>Areas To Contribute</h1>
+<p>The following are areas where significant contributions may be made to
+the GraphicsMagick project:</p>
+<ul class="simple">
+<li>Support building and distributing GraphicsMagick RPMs for Linux.</li>
+<li>Act as formal maintainer for the Gentoo Linux GraphicsMagick ebuild so
+that it is added back to Portage. This is not difficult since the
+ebuild has been actively maintained via the Gentoo bug tracking system.
+At the very least, registering a vote for the Gentoo bug may be helpful.
+See <a class="reference external" href="http://bugs.gentoo.org/show_bug.cgi?id=190372">http://bugs.gentoo.org/show_bug.cgi?id=190372</a>.</li>
+<li>Set up an FTP mirror site for GraphicsMagick.</li>
+<li>Create a language interface using SWIG <<a class="reference external" href="http://www.swig.org/">http://www.swig.org/</a>> to
+support scripting in Perl, Python, TCL/TK, Guile, MzScheme, Ruby,
+Java, PHP, and CHICKEN, based on a common implementation.</li>
+<li>Create a new utility command parser based on a separate LALR or
+XML-based syntax definition, and using an approach suitable to
+replace the existing error-prone command parsers in magick/command.c</li>
+<li>Create a vector encoder for EPS, Postscript, PDF, SVG
+<<a class="reference external" href="http://www.w3.org/Graphics/SVG/">http://www.w3.org/Graphics/SVG/</a>>, Macromedia Flash
+(SWF), WebCGM <<a class="reference external" href="http://www.w3.org/Graphics/WebCGM/">http://www.w3.org/Graphics/WebCGM/</a>>, or WMF.</li>
+<li>Create an OpenEXR coder based on the OpenEXR
+<<a class="reference external" href="http://www.openexr.com/">http://www.openexr.com/</a>> library from Industrial Light & Magic.</li>
+<li>Create a <em>pstoedit</em> module to import Postscript, EPS, and PDF
+files as vector data using pstoedit <<a class="reference external" href="http://www.pstoedit.net/">http://www.pstoedit.net/</a>> which
+already includes a high-quality driver to render Postscript vectors via
+GraphicsMagick. This module could also export vector data in many
+formats using pstoedit's output drivers.</li>
+<li>Work on adding EXIF profile writing support which works for JPEG and
+TIFF formats.</li>
+<li>Add integrated Adobe XMP
+<<a class="reference external" href="http://www.adobe.com/products/xmp/index.html">http://www.adobe.com/products/xmp/index.html</a>> profile support for
+TIFF, JPEG, PNG, PDF, EPS, and Postscript.</li>
+<li>Port Erik Reinhard's super-cool Parameter Estimation For
+Photographic Tone Reproduction
+<<a class="reference external" href="http://www.cs.ucf.edu/~reinhard/Reinhard02/">http://www.cs.ucf.edu/~reinhard/Reinhard02/</a>> algorithm to
+GraphicsMagick.</li>
+<li>Create a replacement (using a portable Widget set such as FLTK) for the
+IMDisplay Windows GUI program and possibly the X11 'display' program.</li>
+<li>Create an interface between GraphicsMagick and OpenOffice.org.
+<<a class="reference external" href="http://www.openoffice.org/">http://www.openoffice.org/</a>> so that OpenOffice may load and save
+any format supported by GraphicsMagick. OpenOffice.org offers a
+separate SDK so there may be a number of other opportunities to
+explore.</li>
+<li>Complete the port of ralcgm to Windows so that it may be used as a
+delegate under Windows.</li>

+<p>GraphicsMagick uses an ASCII string known as "magick" (e.g. "GIF") to
+identify file formats, algorithms acting as formats, built-in images, and
+embedded profile types. After a file has been read or "pinged", the
+associated magick string is stored in the "magick" member of the Image
+structure, and is reported in the default output of 'gm identify'.</p>
+<p>GraphicsMagick supports reading over 88 major file formats (not including
+sub-formats). The following table provides a summary of the supported
+image formats.</p>

+<p>Check <a class="reference external" href="http://www.GraphicsMagick.org/">http://www.GraphicsMagick.org/</a> for the latest version of this page.</p>
+<p>GraphicsMagick is the swiss army knife of image processing. Comprised
+of 267K physical lines (according to David A. Wheeler's <a class="reference external" href="http://www.dwheeler.com/sloccount/">SLOCCount</a>)
+of source code in the base package (or 1,225K including 3rd party
+libraries) it provides a robust and efficient collection of tools and
+libraries which support reading, writing, and manipulating an image in
+over 89 major formats including important formats like DPX, GIF, JPEG,
+JPEG-2000, PNG, PDF, PNM, TIFF, and WebP.</p>
+<p>Image processing is multi-threaded using <a class="reference external" href="http://www.openmp.org/">OpenMP</a> (<a class="reference external" href="OpenMP.html">read about OpenMP
+in GraphicsMagick</a>) so that CPU-bound tasks scale linearly as
+processor cores are added. <a class="reference external" href="http://www.openmp.org/">OpenMP</a> support requires compilation with
+GCC 4.2 (or later), or use of any C compiler supporting at least the
+<a class="reference external" href="http://www.openmp.org/">OpenMP</a> 2.0 specification.</p>
+<p>GraphicsMagick is quite portable, and compiles under almost every general
+purpose operating system that runs on 32-bit or 64-bit CPUs.
+GraphicsMagick is available for virtually any Unix or Unix-like system,
+including Linux. It also runs under <a class="reference external" href="INSTALL-windows.html">Windows</a>
+2000 and later (Windows 2000, XP, Vista, 7, 8.X, 10), and MacOS-X.</p>
+<p>GraphicsMagick supports huge images and has been tested with
+gigapixel-size images. GraphicsMagick can create new images on the
+fly, making it suitable for building dynamic Web
+applications. GraphicsMagick may be used to resize, rotate, sharpen,
+color reduce, or add special effects to an image and save the result
+in the same or different image format. Image processing operations are
+available from the command line, as well as through C, C++, Lua, Perl,
+PHP, Python, Tcl, Ruby, Windows .NET, or Windows COM programming
+interfaces. With some modification, language extensions for
+ImageMagick may be used.</p>
+<p>GraphicsMagick is originally derived from <a class="reference external" href="http://www.imagemagick.org/">ImageMagick</a> 5.5.2 as of
+November 2002 but has been completely independent of the ImageMagick
+project since then. Since the fork from ImageMagick many improvements
+have been made (see <a class="reference external" href="NEWS.html">NEWS</a>) by many <a class="reference external" href="authors.html">authors</a> using an open
+development model but without breaking the API or utilities operation.</p>
+<p>Here are some reasons to prefer GraphicsMagick over ImageMagick or
+other popular software:</p>
+<blockquote>
+<ul class="simple">
+<li>GM is more efficient than ImageMagick so it gets the job done
+faster using fewer resources.</li>
+<li>GM is much smaller and lighter than ImageMagick (3-5X smaller
+installation footprint).</li>
+<li>GM is used to process billions of files at the world's largest photo
+sites (e.g. <a class="reference external" href="http://www.kitchensoap.com/2009/04/03/slides-from-web20-expo-2009-and-somethin-else-interestin/">Flickr</a> and <a class="reference external" href="http://codeascraft.etsy.com/2010/07/09/batch-processing-millions-of-images/">Etsy</a>).</li>
+<li>GM does not conflict with other installed software.</li>
+<li>GM suffers from fewer security issues and exploits than ImageMagick.</li>
+<li>GM participates in Google's <a class="reference external" href="https://github.com/google/oss-fuzz">oss-fuzz</a> project (since February, 2018).</li>
+<li>GM <a class="reference external" href="http://www.valgrind.org/">valgrind</a>'s 100% clean (memcheck and helgrind).</li>
+<li>GM passes rigorous memory error testing using <a class="reference external" href="https://github.com/google/sanitizers/wiki/AddressSanitizer">ASan</a>.</li>
+<li>GM passes undefined behavior testing using <a class="reference external" href="https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html">UBSan</a>.</li>
+<li>GM comes with a comprehensive <a class="reference external" href="GraphicsMagick.html">manual page</a>.</li>
+<li>GM provides API and ABI stability and managed releases that you can
+count on (ImageMagick does not).</li>
+<li>GM provides detailed yet comprehensible <a class="reference external" href="Changelog.html">ChangeLog</a> and <a class="reference external" href="NEWS.html">NEWS</a>
+files (ImageMagick does not).</li>
+<li>GM is available for free, and may be used to support both open and
+proprietary applications.</li>
+<li>GM is distributed under an X11-style license (<a class="reference external" href="http://opensource.org/licenses/MIT">MIT License</a>),

+<h1><a class="toc-backref" href="#id12">Gamma Related Topics</a></h1>
+<p>While most computer images are encoded with a gamma of 2.2 (really 2.2
+to 2.6), GraphicsMagick does not attempt to convert images to
+linear-light before applying image processing operations since it is
+not possible to know for sure to know how to do so. Some algorithms
+such as resize, blur, and composition, will produce more accurate
+results when performed on images encoded in a linear-light scaled
+space.</p>
+<p>For a typical sRGB image encoded in a gamma-corrected space with gamma
+2.2, the option <tt class="docutils literal"><span class="pre">-gamma</span> 0.45</tt> (1/2.2 = 0.45) will remove that
+encoding for subsequent algorithms so that they are done in
+linear-light space. When processing is completed, then <tt class="docutils literal"><span class="pre">-gamma</span> 2.2</tt>
+will restore gamma-correction for viewing. It is recommended to use a
+Q16 or Q32 build of GraphicsMagick when doing this since linear-light
+space encoding is not efficient and will lose accuracy if stored with
+less than 14 bits per sample.</p>
+<p>The following documents and pages provide interesting information on
+gamma-related topics:</p>

+<p>Magick Image File Format (MIFF) is a platform-independent format for
+storing bitmap images. MIFF was originally invented by John Cristy for
+ImageMagick, but is also a native format of GraphicsMagick. It is
+useful as an efficient lossless working file format which assures that
+all of the image attributes used by ImageMagick and GraphicsMagick are
+preserved. Several lossless compression algorithms are available in
+order to save space.</p>
+<div class="section" id="description">
+<h1>Description</h1>
+<p>A MIFF image file consist of two sections. The first section is a header
+composed of keywords describing the image in text form. The next section
+is the binary image data. The header is separated from the image data by
+a : character immediately followed by a ctrl-Z.</p>
+<p>The MIFF header is composed entirely of LATIN-1 characters. The fields in
+the header are keyword and value combination in the keyword=value format,
+with each keyword and value separated by an equal sign (=). Each
+keyword=value combination is delimited by at least one control or
+whitespace character. Comments may appear in the header section and are
+always delimited by braces. The MIFF header always ends with a colon (:)
+character, followed by a ctrl-Z character. It is also common to precede
+the colon with a formfeed and a newline character. The formfeed prevents
+the listing of binary data when using more(1) under Unix where the ctrl-Z
+has the same effect with the type command on the Win32 command line.</p>
+<p>It is required that the 'id' keyword be present with the value
+'ImageMagick' (id=ImageMagick) and be the first keyword listed in the
+MIFF header. Files not starting with this keyword/value may be
+rejected. The 'version' keyword must always be emitted for all new
+files with the value '1.0' (version=1.0).</p>
+<p>The MIFF header supports arbitrary LATIN-1 keyword strings. Some
+keyword strings have special interpretation while others are merely
+stored as image attributes. The following is a list of keyword=value
+combinations with special interpretation that may be found in a MIFF
+file:</p>
+<p>background-color=color</p>
+<p>border-color=color</p>
+<p>matte-color=color</p>
+<blockquote>
+these optional keywords reflects the image background, border, and
+matte colors respectively. A color can be a name (e.g. white) or a hex
+value (e.g. #ccc).</blockquote>
+<p>class=DirectClass</p>
+<p>class=PseudoClass</p>
+<blockquote>
+the type of binary image data stored in the MIFF file. If this keyword
+is not present, DirectClass image data is assumed.</blockquote>
+<p>colors=value</p>
+<blockquote>
+the number of colors in a DirectClass image. For a PseudoClass image,
+this keyword specifies the size of the colormap. If this keyword is not
+present in the header, and the image is PseudoClass, a linear 256 color
+grayscale colormap is used with the image data. The maximum number of
+colormap entries is 65535.</blockquote>
+<p>columns=value</p>
+<blockquote>
+the width of the image in pixels. This is a required keyword and has no
+default.</blockquote>
+<p>colorspace=RGB</p>
+<p>colorspace=CMYK</p>
+<blockquote>
+the colorspace of the pixel data. The default is RGB.</blockquote>
+<p>comment={text}</p>

+<p>compression=None</p>
+<p>compression=RLE</p>
+<p>compression=Zip</p>
+<blockquote>

+is not present, the image data is assumed to be uncompressed.</blockquote>
+<p>delay <1/100ths of a second></p>
+<blockquote>
+the interframe delay in an image sequence. The maximum delay is 65535.</blockquote>
+<p>depth=8</p>

+<p>depth=32</p>
+<blockquote>
+depth of a single color value representing values from 0 to 255
+(depth 8), 65535 (depth 16), or 4294967295 (depth 32). If this
+keyword is absent, a depth of 8 is assumed. Depth values of 1 to 32

+MIFF.</blockquote>
+<p>iterations value</p>
+<blockquote>
+the number of times an image sequence loops before stopping.</blockquote>
+<p>label={value}</p>

+braces) may appear anywhere before the colon.</p>
+<p>The elements shown in the following table may appear after the header and
+before the image data. These elements appear in the order described in
+the following table if the keyword indicates that they exist.</p>
+<table border="1" class="docutils">

+</tbody>
+</table>
+<p>Next comes the binary image data itself. How the image data is formatted
+depends upon the class of the image as specified (or not specified) by
+the value of the class keyword in the header. All numeric values in the
+binary section are written with the most significant bytes occuring first
+(big-endian ordering).</p>
+<p>DirectClass images (class=DirectClass) are continuous-tone, images stored
+as RGB (red, green, blue), RGBA (red, green, blue, alpha), CMYK (cyan,
+yellow, magenta, black), and CMYKA (cyan, yellow, magenta, black, alpha)
+intensity values as defined by the colorspace and matte keywords. The
+size of each intensity value depends on the depth of the image. The
+depth, number of bytes, and numeric range of each value are shown in the
+following table:</p>
+<blockquote>
+<table border="1" class="docutils">
+<colgroup>
+<col width="21%" />
+<col width="41%" />
+<col width="38%" />
+</colgroup>
+<tbody valign="top">
+<tr><td>Depth</td>
+<td>Bytes Per
+Value</td>
+<td>Value Range</td>
+</tr>
+<tr><td>8</td>
+<td>1</td>
+<td>0..255</td>
+</tr>
+<tr><td>16</td>
+<td>2</td>
+<td>0..65535</td>
+</tr>
+<tr><td>32</td>
+<td>4</td>
+<td>0..4294967295</td>
+</tr>
+</tbody>
+</table>
+</blockquote>
+<p>The alpha value (if it occurs) represents the degree of pixel opacity
+(zero is totally transparent).</p>
+<p>PseudoClass images (class=PseudoClass) are colormapped RGB images. The
+colormap is stored as a series of red, green, and blue pixel values. The
+size of each colormap value depends on the image depth, as shown in the
+following table:</p>
+<blockquote>
+<table border="1" class="docutils">
+<colgroup>
+<col width="19%" />
+<col width="22%" />
+<col width="31%" />
+<col width="28%" />
+</colgroup>
+<tbody valign="top">
+<tr><td>Depth</td>
+<td>Bytes Per
+Value</td>
+<td>Value Range</td>
+<td>Bytes Per
+Colormap Entry</td>
+</tr>
+<tr><td>8</td>
+<td>1</td>
+<td>0..255</td>
+<td>3</td>
+</tr>
+<tr><td>16</td>
+<td>2</td>
+<td>0..65535</td>
+<td>6</td>
+</tr>
+<tr><td>32</td>
+<td>4</td>
+<td>0..4294967295</td>
+<td>12</td>
+</tr>
+</tbody>
+</table>
+</blockquote>
+<p>The number of colormap entries is defined by the colors keyword. The
+colormap data occurs immediately following the header (or image directory
+if the montage keyword is in the header). Immediately following the
+colormap data is the PseudoClass image data. PseudoClass image data is an
+array of index values into the color map. The number of bytes comprising
+the index value depends on the number of colors in the image. The
+following table shows the number of bytes in each colormap index as
+determined by the colors keyword:</p>
+<blockquote>
+<table border="1" class="docutils">
+<colgroup>
+<col width="31%" />
+<col width="31%" />
+<col width="38%" />
+</colgroup>
+<tbody valign="top">
+<tr><td>Colors</td>
+<td>Bytes Per
+Index</td>
+<td>Index Range</td>
+</tr>
+<tr><td><=256</td>
+<td>1</td>
+<td>0..255</td>
+</tr>
+<tr><td><=65535</td>
+<td>2</td>
+<td>0..65535</td>
+</tr>
+<tr><td><=4294967295</td>
+<td>4</td>
+<td>0..4294967295</td>
+</tr>
+</tbody>
+</table>
+</blockquote>
+<p>If matte is true, each colormap index is immediately followed by an
+equally-sized alpha value. The alpha value represents the degree of pixel
+opacity (zero is totally transparent).</p>
+<p>The image data in a MIFF file may be uncompressed, runlength encoded,
+Zip compressed, or BZip compressed. The compression keyword in the
+header defines how the image data is compressed. Uncompressed pixels
+are stored one scanline at a time in row order. Runlength encoded
+compression counts runs of identical adjacent pixels and stores the
+pixels followed by a length byte (the number of identical pixels minus
+1). Zip and BZip compression for version 1.0 compresses each row of an
+image and precedes the compressed row with the length of compressed
+pixel bytes as a 32-bit unsigned value in most significant byte first
+order. If the version tag is not present (indicating a virtually
+unused legacy format) then Zip and BZip omit this length value and the
+reader must incrementally decode each row and restart compression at
+the point where decoding completed for the previous row.</p>
+<p>Note that compression in MIFF is scanline-based without any
+specialized pre-processing as is found in the PNG and TIFF file
+formats. As a result, available compression levels are likely to be
+less than some other file formats given the same compression algorithm.</p>
+<p>MIFF files may contain more than one image. Simply concatenate each
+individual image (composed of a header and image data) into one file.</p>

+<p>In November, 2002, the GraphicsMagick project was formed as a branch from
+ImageMagick 5.5.2. The project was formed in order to develop a more
+"stable" form of ImageMagick which is suitable to be use as a base for
+other open source (and proprietary) applications. It was perceived that
+ImageMagick provided tremendous value, but also proved to be difficult to
+rely on as a stable application component since the ImageMagick
+interfaces often changed between releases, and there was no concept of
+shared library ABI stability. GraphicsMagick intends to resolve these
+issues while providing an appealing development environment to attract
+the best available developers.</p>
+<p>The objectives of the GraphicsMagick project are to:</p>
+<ul class="simple">
+<li>Use an open development model.</li>
+<li>Encourage new developers to join the project.</li>
+<li>Avoid unnecessary source code "churn".</li>
+<li>Establish and preserve both a stable API, and stable ABI, making
+GraphicsMagick a stable component in Linux and BSD distributions.</li>
+<li>Use efficient coding practices which result in fast code.</li>
+<li>Improve memory efficiency.</li>
+<li>Use a release process which assures a working product.</li>
+<li>Prioritize bug-fixes over new feature enhancements.</li>
+<li>Maintain an accurate change log.</li>
+<li>Value, and respect the contributions of developers, and observe and
+respect the copyrights of other projects.</li>

+<p>GraphicsMagick supports legacy Legacy 10-bit Kodak Cineon format as
+well as high-grade support for <a class="reference external" href="http://www.smpte.org/">SMPTE</a> DPX Version 2.0 (<a class="reference external" href="http://www.smpte.org/">SMPTE</a>
+268M-2003). SMPTE DPX RGB and YCbCr colorspaces are supported. The
+DPX implementation supports 8, 10, 12, and 16 bits/sample and any
+arbitrary image pixel size. The Cineon implementation supports 8 and
+10 bits/sample.</p>
+<p>Film images are usually captured at <em>2K</em> resolution (82 pixels/mm),
+<em>4K</em> resolution (164 pixels/mm), or even <em>8K</em> resolution (328
+pixels/mm), where the actual resolution values approximate the
+horizontal dimension of the image. A table of <a class="reference external" href="http://www.surrealroad.com/digital/index.php/archives/2005/standard-data-resolutions/">typical pixel
+resolutions</a> for various film sizes may be found on the <a class="reference external" href="http://blog.surrealroad.com//">Surreal
+Road</a> site (table reproduced here for convenience). File sizes may be
+quite large and range in size from 8MB to as much as 180MB. The common
+10-bit <em>2K</em> format consumes 12MB of disk while a 10-bit <em>4K</em> scan
+consumes 50MB of disk.</p>

+<h1><a class="toc-backref" href="#id2">Applications</a></h1>
+<p>The strength of GraphicsMagick versus specialized proprietary software
+are its cost (absolutely free!), open source availability (user is
+able to fix software flaws or tailor software to meet specific needs),
+general purpose image processing capabilities, deep image capabilities
+(up to 32-bits per sample), excellent performance, platform
+independence, lack of encumbering usage licenses, and robust
+implementation. Examples of areas where GraphicsMagick may be used
+are:</p>
+<blockquote>
+<ul class="simple">
+<li>View the image on a display.</li>
+<li>Scaling (for example, <em>4K</em> to <em>2K</em> or 1920x1080 HD with excellent quality)</li>
+<li>Cropping</li>
+<li>Rotation</li>
+<li>Filtering</li>
+<li>ICC ICM profile-based color management and transformations</li>
+<li>Gamma adjustment</li>
+<li>Color adjustment</li>
+<li>Conversion to grayscale</li>
+<li>Text annotations</li>
+<li>Compositions</li>
+<li>Drawing on images (for example drawing markers on image)</li>
+<li>Conversion to and from other formats (e.g. Kodak Cineon, TIFF, JPEG, SGI,
+Postscript, PNG, and PNM)</li>
+</ul>
+</blockquote>
+<p>GraphicsMagick's DPX file format support is very comprehensive. It
+goes beyond the DPX format support in other applications by striving
+to implement the complete DPX specification rather than just a few
+commonly used sub-formats. The capabilities of GraphicsMagick's DPX
+support are as follows:</p>

+<p>The software is written efficiently so the performance when reading

+<div class="section" id="image-resize">
+<h2><a class="toc-backref" href="#id9">Image Resize</a></h2>
+<p>GraphicsMagick is easy to use. The following is an example of scaling
+a <em>4K</em> 16 bit scan to a <em>2K</em> <em>Academy</em> 10 bit image using the <a class="reference external" href="convert.html">convert</a>
+command:</p>
+<pre class="literal-block">
+gm convert 4k.dpx -resize 1828x1556 -depth 10 2k.dpx
+</pre>
+<p>The above example uses the default resizing filters which are
+optimized for quality, but take longer than some other filters. The
+<em>box</em> resize filter provides reasonably good scaling in a reasonable
+amount of time:</p>
+<pre class="literal-block">
+gm convert 4k.dpx -filter box -resize 1828x1556 -depth 10 2k.dpx
+</pre>
+<p>The above example command takes about 4 seconds (on an Apple 2.5GHz G5
+PowerMac or Intel 2.4GHz Xeon) to down-convert from a 131MB <em>5K</em>
+(5232x4376) original 16-bit scan from a NorthLight scanner to a 11MB
+<em>2K</em> 10-bit working image. Operations on more typical <em>2K</em> images take
+about a quarter of a second.</p>
+</div>
+<div class="section" id="annotate-image">
+<h2><a class="toc-backref" href="#id10">Annotate Image</a></h2>
+<p>The following example shows how GraphicsMagick's resize capability may
+be combined with its powerful drawing capability to take a full size
+source image and produce a smaller (720x576) version which includes
+the image filename and timecode at the top of the image, and a logo
+<em>bug</em> image in the bottom right corner:</p>
+<pre class="literal-block">
+gm convert infile.dpx -resize '720x576!' \
+ -draw 'fill "white";text-undercolor "Blue";font "Helvetica";font-size 18;\
+ text 10,20 "%f (%[DPX:tv.time.code])";image atop 500,400 0,0 "gm-125x80t.png"' \
+ outfile.dpx
+</pre>
+<p>As may be seen, the argument to -draw can become extremely long, so to
+make things easy, the drawing commands may be placed in a simple text
+file and passed by reference to the draw comand:</p>
+<p>First lets check what we edited into our drawing command file:</p>
+<pre class="literal-block">
+% cat drawcmd.txt
+fill "white"
+text-undercolor "Blue"
+font "Helvetica"
+font-size 18
+text 10,20 "%f (%[DPX:tv.time.code])"
+image atop 500,400 "0,0 "gm-125x80t.png"
+</pre>
+<p>and now we can apply it by passing the filename prefixed with a '@' to the
+-draw command:</p>
+<pre class="literal-block">
+gm convert infile.dpx -resize '720x576!' -draw '@drawcmd.txt' outfile.dpx
+</pre>
+<p>The <tt class="docutils literal">0,0</tt> in the image composition command argument says to use the
+image as is. If the composited image should be automatically resized,
+then simply replace the <tt class="docutils literal">0,0</tt> with the desired size.</p>
+<p>There are a number of powerful scripting environments for
+GraphicsMagick. One of these is RMagick (Ruby language interface to
+GraphicsMagick). In Ruby, the same effect may be obtained via a script
+that looks like:</p>
+<pre class="literal-block">
+#! /usr/local/bin/ruby -w
+require 'RMagick'
+include Magick
+img = Image.read('infile.dpx')[0]
+frog = Image.read('gm-125x80t.png')[0]
+gc = Draw.new
+gc.fill('white')
+gc.text_undercolor("Blue")
+gc.font("Helvetica")
+gc.font_size(18)
+gc.text(10, 20, "%f (%[DPX:tv.time.code])")
+gc.composite(500, 400, 0, 0, frog, AtopCompositeOp)
+gc.draw(img)
+img.write('outfile.dpx')
+</pre>
+<p>In addition to Ruby, there are scripting interfaces for Perl, Python,
+Tcl, and Ch (C-like scripting language).</p>
+</div>
+<div class="section" id="colorspace-transformation">
+<h2><a class="toc-backref" href="#id11">Colorspace Transformation</a></h2>
+<p>To convert an RGB file to a 4:2:2 YCbCr file in Rec 709 space:</p>

+(if necessary) to ensure that the existing image file is not damaged
+if something goes wrong (e.g., not enough disk space). Note that
+unlike some applications supporting DPX/Cineon, when a file is modifed
+<em>in-place</em> , it is completely re-written. While GraphicsMagick makes

+gm mogrify -resize 1828x1556 -depth 10 file-0001.dpx file-0002.dpx
+</pre>
+<p>Multiple files may be specified on the command line so the same
+command may process hundreds of files in one invocation.</p>
+<p>Unix users can use the find and xargs programs to perform operations
+on any number of files:</p>
+<pre class="literal-block">
+find /assets/001 -name '*.dpx' -print | \
+ xargs gm mogrify -resize 1828x1556 -depth 10
+</pre>
+<p>Xargs works by pasting as many file names as possible on the end of
+the command provided to it.</p>
+<p>The GNU version of xargs provides an added benefit. It is able to run
+several commands in the background. This means that if your system has
+multiple CPUs, it can take advantage of all the CPUs while still using
+one command:</p>
+<pre class="literal-block">
+find /assets/001 -name '*.dpx' -print | \
+ xargs --max-procs 3 --max-args 25 gm mogrify -resize 1828x1556 -depth 10
+</pre>
+<p>The mogrify command supports the -output-directory option to sent
+files to a different directory than the input files. This allows
+processing a large number of files without overwriting the input
+files:</p>
+<pre class="literal-block">
+mkdir dest
+cd source
+gm mogrify -output-directory ../dest -resize 1828x1556 -depth 10 '*.dpx'
+</pre>
+<p>Note that the entire input file path specification is preserved when
+composing the output path so that the input file path is simply
+appended to the output directory path. Also, unless the
+-create-directories option is added, the user is responsible for
+creating any necessary destination directories. As an example of the
+path composition algorithm, if the input file name is specified as
+source/file.dpx and the output directory is specified as dest, then
+the output file path will be dest/source/file.dpx.</p>
+<p>Here is an incantation which recursively processes all DPX files under
+source and sends the result to a similar directory tree under dest.</p>
+<pre class="literal-block">
+mkdir dest
+cd source
+find . name '*.dpx' -print | xargs gm mogrify -output-directory ../dest \
+ -create-directories -resize 1828x1556 -depth 10
+</pre>

+<div class="section" id="creating-a-contact-sheet">
+<h2><a class="toc-backref" href="#id13">Creating A Contact Sheet</a></h2>
+<p>GraphicsMagick may be used to create a contact sheet (grid of
+thumbnails with name and size) by using the <em>VID</em> pseudoformat which
+accepts a wildcarded argument of files (protected by quotes!) to
+read. The output files are buffered while files are being read so
+there is a practical limit to the number of files which may be
+processed at once. To output to a Postscript file:</p>
+<pre class="literal-block">
+gm convert "vid:*.dpx" "contact-sheet.ps"
+</pre>
+<p>or to a PDF file:</p>
+<pre class="literal-block">
+gm convert "vid:*.dpx" "contact-sheet.pdf"
+</pre>
+<p>or to a sequence of JPEG files ranging from contact-sheet-000.jpg to
+contact-sheet-999.jpg:</p>
+<pre class="literal-block">
+gm convert "vid:*.dpx" "contact-sheet-%03d.jpg"
+</pre>
+<p>or to a MIFF file which may be used to interactively browse the
+original files using 'gm display':</p>
+<pre class="literal-block">
+gm convert "vid:*.dpx" "contact-sheet.miff"
+</pre>
+</div>
+<div class="section" id="animating-a-sequence">
+<h2><a class="toc-backref" href="#id14">Animating A Sequence</a></h2>
+<p>GraphicsMagick may be used to animate an image sequence on an X11
+display using the <a class="reference external" href="animate.html">animate</a> subcommand. Frames are buffered in memory
+(pre-loaded into the X11 server) so the number of frames which may be
+animated at once is limited. GraphicsMagick has been used to animate
+1080P (1920x1080) images at 24 frames per second with at least 300
+frames in the sequence.More frames may be buffered on 64-bit
+systems. Many more frames may be animated by preparing a reduced set
+of frames in advance.</p>
+<p>To visualize an animation at 24 frames per second (delay (1/24)*100) use</p>
+<pre class="literal-block">
+gm animate -delay 4.17 'Frame_*.dpx'
+</pre>
+<p>In order to obtain a preview of a larger sequence, and if the frames
+are numbered, a broader span of time may be animated by selecting
+every 10^th frame (terminating with zero) to animate at 2.4 frames per
+second:</p>
+<pre class="literal-block">
+gm animate -delay 41.7 'Frame_*0.dpx'

+<p>An image frame may be displayed on an X11 server using the <a class="reference external" href="display.html">display</a>
+subcommand. By default the name of the image file is displayed in the
+title bar. By specifying the format of the title, other useful
+information such as the time code (see the DPX Attributes section for

+<h2><a class="toc-backref" href="#id19">Command options</a></h2>
+<p>The following command options are particularly useful when dealing with
+DPX files:</p>
+<dl class="docutils">
+<dt>-colorspace {CineonLog|RGB|Gray|Rec601Luma|Rec709Luma|Rec601YCbCr|Rec709YCbCr}</dt>
+<dd>Specifies the colorspace to be used when saving the DPX
+file. CineonLog selects log encoding according to Kodak Cineon
+specifications. RGB selects linear RGB encoding. Gray selects
+linear gray encoding similar to RGB, but with a single
+channel. Rec601Luma requests that RGB is converted to a gray image
+using Rec601 Luma. Rec709Luma requests that RGB is converted to a
+gray image using Rec709Luma. Rec601YCbCr requests that the image
+is saved as YCbCr according to Rec601 (SDTV)
+specifications. Rec709CbCr requests that the image is saved as
+YCbCr according to Rec709 (HDTV) specifications.</dd>
+<dt>-endian {lsb|msb}</dt>
+<dd>Specifies the endian order to use when writing the DPX
+file. GraphicsMagick writes big-endian DPX files by default since
+they are the most portable. Other implementations may use the
+native order of the host CPU (e.g. little-endian when using an
+Intel 'x86 CPU).</dd>
+<dt>-depth <value></dt>
+<dd>Specifies the number of bits to preserve in a color sample. By
+default the output file is written with the same number of bits as
+the input file. For example, if the input file is 16 bits, it may
+be reduced to 10 bits via '-depth 10'.</dd>
+<dt>-define dpx:bits-per-sample=<value></dt>
+<dd>If the dpx:bits-per-sample key is defined, GraphicsMagick will
+write DPX images with the specified bits per sample, overriding
+any existing depth value. If this option is not specified, then
+the value is based on the existing image depth value from the
+original image file. The DPX standard supports bits per sample
+values of 1, 8, 10, 12, and 16. Many DPX readers demand a sample
+size of 10 bits with type A padding (see below).</dd>
+<dt>-define dpx:colorspace={rgb|cineonlog}</dt>
+<dd>Use the dpx:colorspace option when reading a DPX file to specify
+the colorspace the DPX file uses. This overrides the colorspace
+type implied by the DPX header (if any). Currently files with the
+transfer characteristic Printing Density are assumed to be log
+encoded density while files marked as Linear are assumed to be
+linear. Hint: use <tt class="docutils literal"><span class="pre">-define</span> dpx:colorspace=rgb</tt> in order to avoid
+the log to linear transformation for DPX files which use Printing
+Density.</dd>
+<dt>-define dpx:packing-method={packed|a|b|lsbpad|msbpad}</dt>
+<dd>DPX samples may be output within 32-bit words. They may be tightly
+packed end-to-end within the words ("packed"), padded with null
+bits to the right of the sample ("a" or "lsbpad"), or padded with
+null bits to the left of the sample ("b" or "msbpad"). This option
+only has an effect for sample sizes of 10 or 12 bits. If samples
+are not packed, the DPX standard recommends type A padding. Many
+DPX readers demand a sample size of 10 bits with type A padding.</dd>
+<dt>-define dpx:pixel-endian={lsb|msb}</dt>
+<dd>DPX pixels should use the endian order that the DPX header
+specifies. Sometimes there is a mis-match and the pixels use a
+different endian order than the file header specifies. For
+example, the file header may specify little endian, but the pixels
+are in big-endian order. To work around that use -define
+dpx-pixel-endian=msb when reading the file. Likewise, this option
+may be used to intentionally write the pixels using a different
+order than the header.</dd>
+<dt>-define dpx:swap-samples={true|false}</dt>
+<dd>GraphicsMagick strives to adhere to the DPX standard but certain
+aspects of the standard can be quite confusing. As a result, some
+10-bit DPX files have Red and Blue interchanged, or Cb and Cr
+interchanged due to an different interpretation of the standard,
+or getting the wires crossed. The swap-samples option may be
+supplied when reading or writing in order to read or write using
+the necessary sample order.</dd>
+<dt>-interlace plane</dt>
+<dd>By default, samples are stored contiguously in a single element
+when possible. Specifying '-interlace plane' causes each sample
+type (e.g. 'red') to be stored in its own image element. Planar
+storage is fully supported for grayscale (with alpha) and RGB. For
+YCbCr, chroma must be 4:2:2 subsampled in order to use planar
+storage. While planar storage offers a number of benefits, it
+seems that very few DPX-supporting applications support it.</dd>
+<dt>-sampling-factor 4:2:2</dt>
+<dd>Select 4:2:2subsampling when saving an image in YCbCr
+format. Subsampling is handled via a general-purpose image resize
+algorithm (lanczos) rather than a dedicated filter so subsampling
+is slow (but good).</dd>
+<dt>-set reference-white <value></dt>
+<dd>Set the 90% white card level (default 685) for Cineon Log.</dd>
+<dt>-set reference-black <value></dt>
+<dd>Set the 1% black card level (default 95) for Cineon Log.</dd>
+<dt>-set display-gamma <value></dt>
+<dd>Set the display gamma (default 1.7) for Cineon Log.</dd>
+<dt>-set film-gamma <value></dt>
+<dd>Set the film gamma (default 0.6) for Cineon Log.</dd>
+<dt>-set soft-clip-offset <value></dt>

+<p>PerlMagick is an objected-oriented Perl interface to GraphicsMagick. Use
+the module to read, manipulate, or write an image or image sequence from
+within a Perl script. This makes it very suitable for Web CGI scripts.
+You must have GraphicsMagick 1.0.0 or above and Perl version 5.005_02 or
+greater installed on your system for either of these utilities to work.
+There are a number of useful scripts available to show you the value of
+PerlMagick. The PerlMagick demo directory provides a number of sample
+demos.</p>

+<h2><a class="toc-backref" href="#id3">UNIX</a></h2>
+<p>PerlMagick is installed by default by installing GraphicsMagick.
+Installing PerlMagick as a subordinate package of GraphicsMagick is the
+best way to avoid problems.</p>
+<p>For Unix, you typically need to be root to install the software. There
+are ways around this. Consult the Perl manual pages for more information.</p>
+</div>
+<div class="section" id="windows-xp-windows-8">
+<h2><a class="toc-backref" href="#id4">Windows XP - Windows 8</a></h2>
+<p>Please note that a nice GUI installer is available for GraphicsMagick.
+PerlMagick is included in this installer. If you are using the installer,
+then there is no need to compile PerlMagick.</p>
+<p>After GraphicsMagick has been compiled from the GraphicsMagick Windows
+source distribution using Microsoft Visual C++, PerlMagick may be
+manually built and installed by opening a CLI window and performing the
+following steps:</p>
+<pre class="literal-block">
+cd PerlMagick
+copy Makefile.nt Makefile.PL
+perl Makefile.PL
+nmake
+nmake install

+<p>Any script that wants to use PerlMagick methods must first define the
+methods within its namespace and instantiate an image object. Do this
+with</p>
+<pre class="literal-block">
+use Graphics::Magick;
+$image=Graphics::Magick->new;
+</pre>
+<p>Note that this differs from the ImageMagick version of PerlMagick which
+uses the namespace Image::Magick. Any PerlMagick code written for the
+ImageMagick version of PerlMagick requires a global substition of
+Image::Magick to Graphics::Magick in order to work with the
+GraphicsMagick version.</p>
+<p>The new() method takes the same parameters as SetAttribute . For example:</p>
+<pre class="literal-block">
+$image=Graphics::Magick->new(size=>'384x256');
+</pre>
+<p>Next you will want to read an image or image sequence, manipulate it, and
+then display or write it. The input and output methods for PerlMagick are
+defined in Read or Write an Image. See Set an Image Attribute for methods
+that affect the way an image is read or written. Refer to Manipulate an
+Image for a list of methods to transform an image. Get an Image Attribute
+describes how to retrieve an attribute for an image. Refer to Create an
+Image Montage for details about tiling your images as thumbnails on a
+background. Finally, some methods do not neatly fit into any of the
+categories just mentioned. Review Miscellaneous Methods for a list of
+these methods.</p>
+<p>Once you are finished with a PerlMagick object you should consider
+destroying it. Each image in an image sequence is stored in either
+virtual memory or as a file in the system's temporary file directory.
+This can potentially add up to megabytes of memory or disk. Upon
+destroying a PerlMagick object, the memory is returned for use by other
+Perl methods. The recommended way to destroy an object is with undef</p>
+<pre class="literal-block">
+undef $image;
+</pre>
+<p>To delete all the images but retain the Graphics::Magick object use</p>
+<pre class="literal-block">
+@$image = ();
+</pre>
+<p>and finally, to delete a single image from a multi-image sequence, use</p>
+<pre class="literal-block">
+undef $image->[x];
+</pre>
+<p>The next section illustrates how to use various PerlMagick methods to
+manipulate an image sequence.</p>
+<p>Some of the PerlMagick methods require external programs such as
+Ghostscript. This may require an explicit path in your PATH environment
+variable to work properly. For example,</p>
+<pre class="literal-block">
+$ENV{PATH}='/bin:/usr/bin:/usr/local/bin';
+</pre>
+</div>
+<div class="section" id="example-script">
+<h1><a class="toc-backref" href="#id7">Example Script</a></h1>
+<p>Here is an example script to get you started:</p>
+<pre class="literal-block">
+#!/usr/local/bin/perl
+use Graphics::Magick;
+my($image, $status);
+$image = Graphics::Magick->new;
+$status = $image->Read('girl.png', 'logo.png', 'rose.png');
+warn "$status" if "$status";
+$status = $image->Crop(geometry=>'100x100+100+100');
+warn "$status" if "$status";
+$status = $image->Write('x.gif');
+warn "$status" if "$status";
+</pre>
+<p>The script reads three images, crops them, and writes a single image as a
+GIF animation sequence. In many cases you may want to access individual
+images of a sequence. The next example illustrates how this is done:</p>
+<pre class="literal-block">
+#!/usr/local/bin/perl
+use Graphics::Magick;
+my($image, $p, $q);
+$image = new Graphics::Magick;
+$image->Read('x1.png');
+$image->Read('j*.jpg');
+$image->Read('k.miff[1, 5, 3]');
+$image->Contrast();
+for ($x = 0; $image->[x]; $x++)
+{
+ $image->[x]->Frame('100x200') if $image->[x]->Get('magick') eq 'GIF';
+ undef $image->[x] if $image->[x]->Get('columns') < 100;
+}
+$p = $image->[1];
+$p->Draw(stroke=>'red', primitive=>'rectangle', points=>'20,20 100,100');
+$q = $p->Montage();
+undef $image;
+$q->Write('x.miff');
+</pre>
+<p>Suppose you want to start out with a 100 by 100 pixel white canvas with a
+red pixel in the center. Try</p>
+<pre class="literal-block">
+$image = Graphics::Magick->new;
+$image->Set(size=>'100x100');
+$image->ReadImage('xc:white');
+$image->Set('pixel[49,49]'=>'red');
+</pre>
+<p>Or suppose you want to convert your color image to grayscale:</p>
+<pre class="literal-block">
+$image->Quantize(colorspace=>'gray');
+</pre>
+<p>Here we annotate an image with a Taipai TrueType font:</p>
+<pre class="literal-block">
+$text = 'Works like magick!';
+$image->Annotate(font=>'kai.ttf', pointsize=>40, fill=>'green', text=>$text);
+</pre>
+<p>Other clever things you can do with a PerlMagick objects include</p>
+<pre class="literal-block">
+$i = $#$p"+1"; # return the number of images associated with object p
+push(@$q, @$p); # push the images from object p onto object q
+@$p = (); # delete the images but not the object p
+$p->Convolve([1, 2, 1, 2, 4, 2, 1, 2, 1]); # 3x3 Gaussian kernel

+<p>For convenience, methods Write(), Display(), and Animate() can take any
+parameter that SetAttribute knows about. For example,</p>
+<pre class="literal-block">
+$image->Write(filename=>'image.png', compression=>'None');
+</pre>
+<p>Use - as the filename to method Read() to read from standard in or to
+method Write() to write to standard out:</p>
+<pre class="literal-block">
+binmode STDOUT;
+$image->Write('png:-');
+</pre>

+<dd>$image = Graphics::Magick->new;

+</dl>
+<p>and to write the image back to the disk file, use:</p>
+<pre class="literal-block">
+$status = $image->Write($filename);
+</pre>
+<p>To read an image in the GIF format from a PERL filehandle, use:</p>
+<pre class="literal-block">
+$image = Graphics::Magick->new;
+open(IMAGE, 'image.gif');
+$status = $image->Read(file=>\*IMAGE);
+close(IMAGE);
+</pre>
+<p>To write an image in the PNG format to a PERL filehandle, use:</p>

+$filename = "image.png";
+open(IMAGE, ">$filename");
+$status = $image->Write(file=>\*IMAGE, filename=>$filename);
+close(IMAGE);
+</pre>
+<p>If %0Nd appears in the filename, it is interpreted as a printf format
+specification and the specification is replaced with the specified

+<pre class="literal-block">
+image%03d.miff
+</pre>
+<p>converts files image000.miff, image001.miff, etc.</p>

+<h1><a class="toc-backref" href="#id9">Manipulate an Image</a></h1>
+<p>Once you create an image with, for example, method ReadImage() you may want
+to operate on it. Below is a list of all the image manipulations methods
+available to you with PerlMagick. There are examples of select PerlMagick
+methods. Here is an example call to an image manipulation method:</p>
+<pre class="literal-block">
+$image->Crop(geometry=>'100x100"+1"0+20');
+$image->[x]->Frame("100x200");
+</pre>
+<p>Image method parameters are often redundant. For example, a 'geometry'
+string parameter (e.g. 800x600+10+20) is equivalent to the explicit use of
+width, height, x, and y, parameters.</p>

+<p>Note, that the geometry parameter is a short cut for the width and height

+height=>80).</p>
+<p>You can specify @filename in both Annotate() and Draw(). This reads the
+text or graphic primitive instructions from a file on disk. For example,</p>
+<pre class="literal-block">
+$image->Draw(fill=>'red', primitive=>'rectangle',
+points=>'20,20 100,100 40,40 200,200 60,60 300,300');

+<p>Is equivalent to</p>
+<pre class="literal-block">

+<p>Where draw.txt is a file on disk that contains this:</p>
+<pre class="literal-block">
+rectangle 20, 20 100, 100
+rectangle 40, 40 200, 200
+rectangle 60, 60 300, 300
+</pre>
+<p>The text parameter for methods, Annotate(), Comment(), Draw(), and
+Label() can include the image filename, type, width, height, or other
+image attribute by embedding these special format characters:</p>
+<pre class="literal-block">
+%b file size
+%d comment
+%d directory
+%e filename extension
+%f filename
+%h height
+%m magick
+%p page number
+%s scene number
+%t top of filename
+%w width
+%x x resolution
+%y y resolution
+\n newline
+\r carriage return
+</pre>
+<p>For example,</p>
+<pre class="literal-block">
+text=>"%m:%f %wx%h"
+</pre>
+<p>produces an annotation of MIFF:bird.miff 512x480 for an image titled
+bird.miff and whose width is 512 and height is 480.</p>
+<p>You can optionally add Image to any method name. For example, TrimImage()

+<p>ImageToBlob() returns the image data in their respective formats. You can

+<h1><a class="toc-backref" href="#id14">Miscellaneous Methods</a></h1>
+<p>The Append() method append a set of images. For example,</p>
+<pre class="literal-block">
+$p = $image->Append(stack=>{true,false});
+</pre>
+<p>appends all the images associated with object $image. By default, images
+are stacked left-to-right. Set stack to True to stack them top-to-bottom.</p>
+<p>The Average() method averages a set of images. For example,</p>
+<pre class="literal-block">
+$p = $image->Average();
+</pre>
+<p>averages all the images associated with object $image.</p>
+<p>The Clone() method copies a set of images. For example,</p>
+<pre class="literal-block">
+$p = $image->Clone();
+</pre>
+<p>copies all the images from object $q to $p. You can use this method for
+single or multi-image sequences.</p>
+<p>The Morph() method morphs a set of images. Both the image pixels and size
+are linearly interpolated to give the appearance of a meta-morphosis from
+one image to the next:</p>
+<pre class="literal-block">
+$p = $image->Morph(frames=>integer);
+</pre>
+<p>where frames is the number of in-between images to generate. The default
+is 1.</p>
+<p>Mosaic() creates an mosaic from an image sequence.</p>
+<p>Method Mogrify() is a single entry point for the image manipulation
+methods (Manipulate an Image). The parameters are the name of a method
+followed by any parameters the method may require. For example, these
+calls are equivalent:</p>
+<pre class="literal-block">
+$image->Crop('340x256+0+0');
+$image->Mogrify('crop', '340x256+0+0');
+</pre>
+<p>Method MogrifyRegion() applies a transform to a region of the image. It
+is similar to Mogrify() but begins with the region geometry. For example,
+suppose you want to brighten a 100x100 region of your image at location
+(40, 50):</p>
+<pre class="literal-block">
+$image->MogrifyRegion('100x100+40+50', 'modulate', brightness=>50);
+</pre>
+<p>Ping() is a convenience method that returns information about an image
+without having to read the image into memory. It returns the width,
+height, file size in bytes, and the file format of the image. You can
+specify more than one filename but only one filehandle:</p>
+<pre class="literal-block">
+($width, $height, $size, $format) = $image->Ping('logo.png');
+($width, $height, $size, $format) = $image->Ping(file=>\*IMAGE);
+($width, $height, $size, $format) = $image->Ping(blob=>@blob);
+</pre>
+<p>This is a more efficient and less memory intensive way to query if an
+image exists and what its characteristics are.</p>
+<p>To have full control over text positioning you need font metric
+information. Use</p>
+<pre class="literal-block">
+($x_ppem, $y_ppem, $ascender, $descender, $width, $height, $max_advance) =
+$image->QueryFontMetrics(parameters);
+
+Where parameters is any parameter of the Annotate method. The
+'text' parameter must be specified since there can be no default for
+the text to render. The return values are
+
+* character width
+* character height
+* ascender
+* descender
+* text width
+* text height
+* maximum horizontal advance
+</pre>
+<p>Call QueryColor() with no parameters to return a list of known colors
+names or specify one or more color names to get these attributes: red,
+green, blue, and opacity value.</p>
+<pre class="literal-block">
+@colors = $image->QueryColor();
+($red, $green, $blue, $opacity) = $image->QueryColor('cyan');
+($red, $green, $blue, $opacity) = $image->QueryColor('#716bae');
+</pre>
+<p>QueryColorname() accepts a color value and returns its respective name or
+hex value;</p>
+<pre class="literal-block">
+$name = $image->QueryColorname('rgba(80,60,0,0)');
+</pre>
+<p>Call QueryFont() with no parameters to return a list of known fonts or
+specify one or more font names to get these attributes: font name,
+description, family, style, stretch, weight, encoding, foundry, format,
+metrics, and glyphs values.</p>
+<pre class="literal-block">
+@fonts = $image->QueryFont();
+$weight = ($image->QueryFont('Helvetica'))[5];
+</pre>
+<p>Call QueryFormat() with no parameters to return a list of known image
+formats or specify one or more format names to get these attributes:
+adjoin, blob support, raw, decoder, encoder, description, and module.</p>
+<pre class="literal-block">
+@formats = $image->QueryFormat();
+($adjoin, $blob_support, $raw, $decoder, $encoder, $description, $module) = $image->QueryFormat('gif');
+</pre>
+<p>Use RemoteCommand() to send a command to an already running display or
+animate application. The only parameter is the name of the image file to
+display or animate.</p>
+<p>Finally, the Transform() method accepts a fully-qualified geometry
+specification for cropping or resizing one or more images. For example,</p>
+<pre class="literal-block">
+$p = $image->Transform(crop=>'100x100');
+</pre>
+<p>You can optionally add Image to any method name above. For example,
+PingImage() is an alias for method Ping().</p>

+<h1><a class="toc-backref" href="#id15">Handling Errors</a></h1>
+<p>All PerlMagick methods return an undefined string context upon success. If
+any problems occur, the error is returned as a string with an embedded
+numeric status code. A status code less than 400 is a warning. This means
+that the operation did not complete but was recoverable to some degree. A
+numeric code greater or equal to 400 is an error and indicates the
+operation failed completely. Here is how errors are returned for the
+different methods:</p>
+<blockquote>
+<ul>
+<li><p class="first">Methods which return a number (e.g. Read(), Write()):</p>
+<pre class="literal-block">
+$status = $image->Read(...);
+warn "$status" if "$status"; # print the error message
+$status =~ /(\d+)/;
+print $1; # print the error number
+print 0+$status; # print the number of images read
+</pre>
+</li>
+<li><p class="first">Methods which operate on an image (e.g. Resize(), Crop()):</p>
+<pre class="literal-block">
+$status = $image->Crop(...);

+<p>In order to ensure an orderly development process, and assure the highest
+quality releases, a development process has been established for
+GraphicsMagick.</p>
+<div class="section" id="phases-of-development">
+<h1>Phases of Development</h1>
+<p>Four major development phases have been identified. These are the
+feature development phase, snapshot phase, beta phase, and release
+phase. The phases used depend on the nature of preceding development.
+The Beta phase is usually skipped. The descriptions of these phases
+are as follows:</p>
+<div class="section" id="feature-development-phase">
+<h2>Feature Development Phase</h2>
+<blockquote>
+<p>The feature development phase is a time of rapid development and
+innovation. Work is normally done on Mercurial 'tip'. During the
+feature development phase, Mercurial is the only way to access the
+work in progress. Before updates are committed to Mercurial, they
+should be proven to compile on at least one architecture and pass
+the test suite ('make distcheck').</p>
+<p>Entry Criteria: There is a plan for feature development.</p>
+<p>Exit Criteria: Test suite passes on at least one machine.</p>
+</blockquote>
+</div>
+<div class="section" id="snapshot-phase">
+<h2>Snapshot Phase</h2>
+<blockquote>
+<p>The snapshot phase is entered when it is decided that the work is
+stable enough for non-developers to test. API and user interfaces
+should be stable before the snapshot phase begins in order to avoid
+confusion. Snapshot development is done on Mercurial 'tip'. Snapshot
+packages are identified by the date of the snapshot, and no Mercurial
+branching or tagging is performed to support the snapshot.</p>
+<p>Entry Criteria: Interfaces are stable, and code compiles and runs on
+multiple architectures.</p>
+<p>Exit Criteria: Code is release quality. The test suite must show
+100% completion for Q:8 and Q:16 quantum depths on at least three
+operating environments.</p>
+</blockquote>
+</div>
+<div class="section" id="beta-phase">
+<h2>Beta Phase</h2>
+<blockquote>
+<p>The Beta phase (usually only occuring at the beginning of a major
+release cycle) is entered when the work is feature complete, the
+package passes all tests, and it is considered time for versioned
+releases. As the first step of entering the beta phase, a release
+branch is created off of the trunk to support change sets for the
+release. The purpose of the beta phase is to wring out any remaining
+bugs prior to release. When a beta package is prepared, a release
+tag is applied to the associated release branch in Mercurial.</p>
+<p>Entry Criteria: Code is release quality.. The test suite must show
+100% completion for Q:8 and Q:16 quantum depths on at least three
+operating environments.</p>
+<p>Exit Criteria: The test suite must show 100% completion for Q:8, Q:16,
+and Q:32 quantum depths on at least three operating environments. The
+current beta package is determined to be sufficiently flawless for a
+final release.</p>
+</blockquote>
+</div>
+<div class="section" id="release-phase">
+<h2>Release Phase</h2>
+<blockquote>
+<p>The release phase is entered when the most recent Beta (or snapshot)
+is considered to be of acceptable quality for a release or bug-fixes
+have been prepared based on a previous release. At this time, a
+formal release tag is applied to the release branch, and release
+packages are created. Once a release tag has been applied to a
+release branch, that release branch is considered to be in release
+state and may only be used to prepare additional releases intended
+to correct bugs found in preceding releases. The initial release on
+a release branch has a two-digit (i.e. X.X) release
+designation. Bug-fix releases have a three-digit (i.e. X.X.X)
+release designation. A release designation may only be used once. If
+a problem is discovered with the release package, a new release
+number is assigned to support the corrected release package.</p>
+<p>Entry Criteria: The test suite must show 100% completion for Q:8, Q:16,
+and Q:32 quantum depths on at least three operating environments. The
+current beta package is determined to be sufficiently flawless for a
+final release.</p>
+<p>Exit Criteria: None</p>

+This document describes how GraphicsMagick performs color
+reduction on an image. To fully understand this document,
+you should have a knowledge of basic imaging techniques and
+the tree data structure and terminology.</blockquote>
+<div class="section" id="description">
+<h1>Description</h1>
+<p>For purposes of color allocation, an image is a set of n pixels, where
+each pixel is a point in RGB space. RGB space is a 3-dimensional vector
+space, and each pixel, p(i), is defined by an ordered triple of red,
+green, and blue coordinates, (r(i),g(i),b(i)).</p>
+<p>Each primary color component (red, green, or blue) represents an
+intensity which varies linearly from 0 to a maximum value, Cmax, which
+corresponds to full saturation of that color. Color allocation is defined
+over a domain consisting of the cube in RGB space with opposite vertices
+at (0,0,0) and (Cmax ,Cmax,Cmax). GraphicsMagick requires Cmax= 255.</p>
+<p>The algorithm maps this domain onto a tree in which each node represents
+a cube within that domain. In the following discussion, these cubes are
+defined by the coordinate of two opposite vertices: The vertex nearest
+the origin in RGB space and the vertex farthest from the origin.</p>
+<p>The tree's root node represents the the entire domain, (0,0,0) through
+(Cmax, Cmax,Cmax). Each lower level in the tree is generated by
+subdividing one node's cube into eight smaller cubes of equal size. This
+corresponds to bisecting the parent cube with planes passing through the
+midpoints of each edge.</p>
+<p>The basic algorithm operates in three phases:</p>
+<blockquote>
+<ul class="simple">
+<li>Classification,</li>
+<li>Reduction, and</li>
+<li>Assignment.</li>
+</ul>
+</blockquote>
+<p>Classification builds a color description tree for the image. Reduction
+collapses the tree until the number it represents, at most, is the number
+of colors desired in the output image. Assignment defines the output
+image's color map and sets each pixel's color by reclassification in the
+reduced tree. Our goal is to minimize the numerical discrepancies between
+the original colors and quantized colors. To learn more about
+quantization error, see Measuring Color Reduction Error later in this
+document.</p>
+<p>Classification begins by initializing a color description tree of
+sufficient depth to represent each possible input color in a leaf.
+However, it is impractical to generate a fully-formed color description
+tree in the classification phase for realistic values of Cmax. If color
+components in the input image are quantized to k-bit precision, so that
+Cmax = 2^k-1, the tree would need k levels below the root node to allow
+representing each possible input color in a leaf. This becomes
+prohibitive because the tree's:</p>
+<pre class="literal-block">
+total number of nodes = 1+Sum(8^i), i=1,k
+
+For k=8,
+Number of nodes= 1 + (8^1+8^2+....+8^8)
+8^8 - 1
+= 1 + 8.-----------
+8 - 1
+= 19,173,961
+</pre>
+<p>Therefore, to avoid building a fully populated tree, GraphicsMagick:</p>
+<ol class="arabic simple">
+<li>Initializes data structures for nodes only as they are needed;</li>
+<li>Chooses a maximum depth for the tree as a function of the desired
+number of colors in the output image (currently based-two logarithm
+of Cmax).</li>
+</ol>
+<p>For Cmax=255,</p>
+<pre class="literal-block">
+Maximum tree depth = log (256)
+2
+
+= log (256) / log (2)
+e e
+
+= 8
+</pre>
+<p>A tree of this depth generally allows the best representation of the
+source image with the fastest computational speed and the least amount of
+memory. However, the default depth is inappropriate for some images.
+Therefore, the caller can request a specific tree depth.</p>
+<p>For each pixel in the input image, classification scans downward from the
+root of the color description tree. At each level of the tree, it
+identifies the single node which represents a cube in RGB space
+containing the pixel's color. It updates the following data for each such
+node:</p>
+<blockquote>
+<dl class="docutils">
+<dt>n1:</dt>
+<dd>Number of pixels whose color is contained in the RGB cube which
+this node represents;</dd>
+<dt>n2:</dt>
+<dd>Number of pixels whose color is not represented in a node at lower
+depth in the tree; initially, n2=0 for all nodes except leaves of
+the tree.</dd>
+<dt>Sr,Sg,Sb:</dt>
+<dd>Sums of the red, green, and blue component values for all pixels
+not classified at a lower depth. The combination of these sums and
+n2 will ultimately characterize the mean color of a set of pixels
+represented by this node.</dd>
+<dt>E:</dt>
+<dd>The distance squared in RGB space between each pixel contained
+within a node and the nodes' center. This represents the
+quantization error for a node.</dd>
+</dl>
+</blockquote>
+<p>Reduction repeatedly prunes the tree until the number of nodes with n2 >
+0 is less than or equal to the maximum number of colors allowed in the
+output image. On any given iteration over the tree, it selects those
+nodes whose E value is minimal for pruning and merges their color
+statistics upward. It uses a pruning threshold, Ep, to govern node
+selection as follows:</p>
+<pre class="literal-block">
+Ep = 0
+while number of nodes with (n2 > 0) > required maximum number of colors
+prune all nodes such that E <= Ep
+Set Ep to minimum E in remaining nodes
+</pre>
+<p>This has the effect of minimizing any quantization error when merging two
+nodes together.</p>
+<p>When a node to be pruned has offspring, the pruning procedure invokes
+itself recursively in order to prune the tree from the leaves upward. The
+values of n2 ,Sr, Sg and Sb in a node being pruned are always added to
+the corresponding data in that node's parent. This retains the pruned
+node's color characteristics for later averaging.</p>
+<p>For each node, n2 pixels exist for which that node represents the
+smallest volume in RGB space containing those pixel's colors. When n2 > 0
+the node will uniquely define a color in the output image. At the
+beginning of reduction, n2 = 0 for all nodes except the leaves of the
+tree which represent colors present in the input image.</p>
+<p>The other pixel count, n1, indicates the total number of colors within
+the cubic volume which the node represents. This includes n1 - n2 pixels
+whose colors should be defined by nodes at a lower level in the tree.</p>
+<p>Assignment generates the output image from the pruned tree. The output
+image consists of two parts:</p>
+<ol class="arabic simple">
+<li>A color map, which is an array of color descriptions (RGB triples)
+for each color present in the output image.</li>
+<li>A pixel array, which represents each pixel as an index into the
+color map array.</li>
+</ol>
+<p>First, the assignment phase makes one pass over the pruned color
+description tree to establish the image's color map. For each node with
+n2 > 0, it divides Sr, Sg, and Sb by n2. This produces the mean color of
+all pixels that classify no lower than this node. Each of these colors
+becomes an entry in the color map.</p>
+<p>Finally, the assignment phase reclassifies each pixel in the pruned tree
+to identify the deepest node containing the pixel's color. The pixel's
+value in the pixel array becomes the index of this node's mean color in
+the color map.</p>
+<p>Empirical evidence suggests that the distances in color spaces such as
+YUV, or YIQ correspond to perceptual color differences more closely than
+do distances in RGB space. These color spaces may give better results
+when color reducing an image. Here the algorithm is as described except
+each pixel is a point in the alternate color space. For convenience, the
+color components are normalized to the range 0 to a maximum value, Cmax.
+The color reduction can then proceed as described.</p>
+</div>
+<div class="section" id="measuring-color-reduction-error">
+<h1>Measuring Color Reduction Error</h1>
+<p>Depending on the image, the color reduction error may be obvious or
+invisible. Images with high spatial frequencies (such as hair or grass)
+will show error much less than pictures with large smoothly shaded areas
+(such as faces). This is because the high-frequency contour edges
+introduced by the color reduction process are masked by the high
+frequencies in the image.</p>
+<p>To measure the difference between the original and color reduced images
+(the total color reduction error), GraphicsMagick sums over all pixels in
+an image the distance squared in RGB space between each original pixel
+value and its color reduced value. GraphicsMagick prints several error
+measurements including the mean error per pixel, the normalized mean
+error, and the normalized maximum error.</p>
+<p>The normalized error measurement can be used to compare images. In
+general, the closer the mean error is to zero the more the quantized
+image resembles the source image. Ideally, the error should be
+perceptually-based, since the human eye is the final judge of
+quantization quality.</p>
+<p>These errors are measured and printed when -verbose and -colorsare
+specified on the command line:</p>
+<blockquote>
+<dl class="docutils">
+<dt>mean error per pixel:</dt>
+<dd>is the mean error for any single pixel in the image.</dd>
+<dt>normalized mean square error:</dt>
+<dd>is the normalized mean square quantization error for any single
+pixel in the image.
+This distance measure is normalized to a range between 0 and 1. It
+is independent of the range of red, green, and blue values in the
+image.</dd>
+<dt>normalized maximum square error:</dt>
+<dd>is the largest normalized square quantization error for any single
+pixel in the image.
+This distance measure is normalized to a range between and blue
+values in the image.</dd>
+</dl>

+<h1>Background</h1>
+<p>Although GraphicsMagick is image processing software, security is a
+very important consideration for GraphicsMagick. GraphicsMagick may
+be used to open files and URLs produced by an untrusted party. Given
+a suitable weakness (which we make every effort to prevent), an
+intentionally constructed file might be able to cause the software to
+crash, leak memory, request huge amounts of memory, run forever, or in
+the worst case execute arbitrary code, including shell code.
+GraphicsMagick is very powerful and complex software supporting many
+capabilities and so untrusted parties should never be allowed to
+submit arbitrary requests into it.</p>
+<p>GraphicsMagick includes the ability to access arbitrary http and ftp
+URLs as well as local image, font, and SVG files. The SVG renderer
+supports read access to http and ftp URLs as well as local files
+according to the SVG specification. Since URLs and local file paths
+may be included in SVG files, untrusted SVG files may create a Server
+Side Request Forgery (<a class="reference external" href="https://cwe.mitre.org/data/definitions/918.html">SSRF</a>) vulnerability since URL requests are
+done by the computer executing the SVG, which may be in a realm of
+trust (e.g. inside the firewall and able to access "localhost"
+addresses).</p>
+<p>The <cite>-comment</cite>, <cite>-draw</cite>, <cite>-format</cite>, and <cite>-label</cite> utility options
+support a <cite>@filename</cite> syntax to incorporate any readable file on the
+system as a convenience to the user. If text from an untrusted source
+(e.g. a web page) is allowed to supply these options, then they may be
+used to read arbitrary files, creating a potential security hazard.</p>
+<p>The GraphicsMagick project is continually striving to eliminate
+conditions in the software which might pose a risk for its users while
+not constraining what its users may do with the software.</p>
+</div>
+<div class="section" id="reporting-issues">
+<h1>Reporting Issues</h1>
+<p>If you become aware of a serious security issue with GraphicsMagick,
+then it may be addressed by email directly to the GraphicsMagick
+maintainers or to the <a class="reference external" href="mailto:graphicsmagick-security%40graphicsmagick.org">GraphicsMagick Security</a> mail address. More
+minor issues are best addressed via the <a class="reference external" href="https://sourceforge.net/p/graphicsmagick/bugs/">GraphicsMagick Bug Tracker</a>
+at SourceForge. Please remember to set the bug to 'private' if you
+use the bug tracker or else someone may aquire a zero-day exploit from
+your report. We will set the bug to 'public' as soon as a remedy has
+been made available.</p>
+<p>Reporting an issue will allow us to fix it so that future releases of
+the software won't suffer from the problem.</p>
+<p>The current state of free software is that security-sensitive free
+software projects have been undergoing automated testing by machines
+(and sometimes what might be hundreds of machines). Machines do not
+need to work at a day job, take care of families, rest, or eat, but we
+do. Any bug report which comes with a patch or changeset to fix the
+problem is greatly appreciated and helps to move the project forward.</p>
+<p>The remedy available to us is to submit a changeset to the
+GraphicsMagick Mercurial repository, and include the changes in the
+next release. Regardless of how an issue becomes known to us, the
+issue will become public knowledge as soon as we commit a fix to the
+source code repository. Only in exceedingly rare and dire
+circumstances (e.g a previously-unknown zero-day shell exploit) might
+we do anything different.</p>
+</div>
+<div class="section" id="safe-use-of-the-software">
+<h1>Safe Use Of The Software</h1>
+<p>You are the first line of defense when it comes to GraphicsMagick
+security!</p>
+<p>If you are operating a server which supports file uploads from
+untrusted users, or delivered via a network protocol such as http,
+ftp, or email, then you should take steps to assure that a problem
+with opening/processing the file does not place the whole server at
+risk. These are steps which can be taken:</p>
+<ol class="arabic">
+<li><p class="first">Subscribe to the <a class="reference external" href="https://lists.sourceforge.net/lists/listinfo/graphicsmagick-announce">graphicsmagick-announce</a> mailing list so that
+you are informed about new GraphicsMagick releases or special
+security bulletins.</p>
+</li>
+<li><p class="first">Make sure that GraphicsMagick is up to date as reported on the
+GraphicsMagick web site. Don't simply trust that packages from
+your operating system vendor are kept up to date or are updated to
+include security fixes. Keeping GraphicsMagick up to date might
+require that you compile GraphicsMagick yourself from source code.</p>
+</li>
+<li><p class="first">Execute the software in a <a class="reference external" href="https://en.wikipedia.org/wiki/Operating-system-level_virtualization">Container</a>, <a class="reference external" href="https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails.html">FreeBSD Jail</a>, <a class="reference external" href="https://illumos.org/man/5/zones">Solaris
+Zone</a>, or <a class="reference external" href="https://en.wikipedia.org/wiki/Chroot">chrooted</a> environment such that it can not cause harm
+to the system running it.</p>
+</li>
+<li><p class="first">Execute the software as a least-privileged user (e.g. 'nobody').</p>
+</li>
+<li><p class="first">Normalize input file names or any other external inputs so that
+they are under your control and not controlled by an untrusted
+party. This should include any file name specifications, which may
+include arbitrary 'glob' patterns (wildcards) (requiring hours or
+days to complete if sufficiently close long file names exist), and
+options supporting a <cite>@filename</cite> syntax.</p>
+</li>
+<li><p class="first">Enforce that uploaded files are passed to the expected reader. For
+example, the uploaded file "file.jpg" is forced to be read by the
+JPEG reader (rather than a reader selected based on header magic
+testing) by using the file name "jpg:file.jpg". If the file is not
+really what was indicated, then an error is reported.</p>
+<p>GraphicsMagick supports a great many file types and auto-detects
+many file types based on their content rather than file extension.
+The file which pretends to be an ordinary PNG or JPEG file might be
+something else entirely. Note that even using independent file
+header testing may not be sufficient since it is possible to
+construct valid files with a header which appears to be several
+different types, but the first type which matches while testing the
+header will be selected.</p>
+</li>
+<li><p class="first">Apply resource limits via the <cite>-limit</cite> option or the
+<cite>MAGICK_LIMIT_*</cite> environment variables (e.g. <cite>export
+MAGICK_LIMIT_PIXELS=30Mp</cite>, <cite>export MAGICK_LIMIT_MEMORY=500Mb</cite>).
+Also consider setting resource limits using the <cite>ulimit</cite> command.</p>
+</li>
+<li><p class="first">Consider using the <cite>MAGICK_CODER_STABILITY</cite> environment variable to
+constrain the supported file formats to the subsets selected by
+<cite>PRIMARY</cite> or <cite>STABLE</cite>. After setting this environment variable
+(e.g. <cite>export MAGICK_CODER_STABILITY=PRIMARY</cite>), use <cite>gm
+convert -list format</cite> and verify that the format support you need
+is enabled. Selecting the <cite>PRIMARY</cite> or <cite>STABLE</cite> options blocks
+access of http and ftp URLs (<a class="reference external" href="https://cwe.mitre.org/data/definitions/918.html">SSRF</a> vulnerability), but does not
+block SVG renderer access to read local image files.</p>

+<h2>Description</h2>
+<p>DrawPathEllipticArcRelative() draws an elliptical arc from the current
+point to (x, y) using relative coordinates. The size and orientation
+of the ellipse are defined by two radii (rx, ry) and an
+xAxisRotation, which indicates how the ellipse as a whole is rotated
+relative to the current coordinate system. The center (cx, cy) of the
+ellipse is calculated automatically to satisfy the constraints imposed
+by the other parameters. largeArcFlag and sweepFlag contribute to the
+automatic calculations and help determine how the arc is drawn. If
+largeArcFlag is true then draw the larger of the available arcs. If
+sweepFlag is true, then draw the arc matching a clock-wise rotation.</p>

+<h2>Description</h2>
+<p>The MagickHaldClutImage() method apply a color lookup table (Hald CLUT) to
+the image. The fundamental principle of the Hald CLUT algorithm is that
+application of an identity CLUT causes no change to the input image,
+but an identity CLUT image which has had its colors transformed in
+some way (e.g. in Adobe Photoshop) may be used to implement an identical
+transform on any other image.</p>
+<p>The minimum CLUT level is 2, and the maximum depends on available memory
+(largest successfully tested is 24). A CLUT image is required to have equal
+width and height. A CLUT of level 8 is an image of dimension 512x512, a CLUT
+of level 16 is an image of dimension 4096x4096. Interpolation is used so
+extremely large CLUT images are not required.</p>
+<p>GraphicsMagick provides an 'identity' coder which may be used to generate
+identity HLUTs. For example, reading from "identity:8" creates an identity
+CLUT of order 8.</p>
+<p>The Hald CLUT algorithm has been developed by Eskil Steenberg as described
+at <a class="reference external" href="http://www.quelsolaar.com/technology/clut.html">http://www.quelsolaar.com/technology/clut.html</a>, and was adapted for
+GraphicsMagick by Clément Follet with support from Cédric Lejeune of

+</div>
+<div class="section" id="id328">
+<h2>Description</h2>
+<p>MagickSetCompressionQuality() sets the image quality factor, which
+determines compression options when saving the file.</p>
+<p>For the JPEG and MPEG image formats, quality is 0 (lowest image
+quality and highest compression) to 100 (best quality but least
+effective compression). The default quality is 75. Use the
+-sampling-factor option to specify the factors for chroma
+downsampling. To use the same quality value as that found by the
+JPEG decoder, use the -define jpeg:preserve-settings flag.</p>
+<p>For the MIFF image format, and the TIFF format while using ZIP
+compression, quality/10 is the zlib compres- sion level, which is 0
+(worst but fastest compression) to 9 (best but slowest). It has no
+effect on the image appearance, since the compression is always
+lossless.</p>
+<p>For the JPEG-2000 image format, quality is mapped using a non-linear
+equation to the compression ratio required by the Jasper library.
+This non-linear equation is intended to loosely approximate the
+quality provided by the JPEG v1 format. The default quality value 75
+results in a request for 16:1 compression. The quality value 100
+results in a request for non-lossy compres- sion.</p>
+<p>For the MNG and PNG image formats, the quality value sets the zlib
+compression level (quality / 10) and filter-type (quality % 10).
+Compression levels range from 0 (fastest compression) to 100 (best
+but slowest). For compression level 0, the Huffman-only strategy is
+used, which is fastest but not necessarily the worst compression. If
+filter-type is 4 or less, the specified filter-type is used for all
+scanlines:</p>
+<ol class="arabic simple" start="0">
+<li>none</li>
+<li>sub</li>
+<li>up</li>
+<li>average</li>
+<li>Paeth</li>
+</ol>
+<p>If filter-type is 5, adaptive filtering is used when quality is
+greater than 50 and the image does not have a color map, otherwise no
+filtering is used.</p>
+<p>If filter-type is 6, adaptive filtering with minimum-
+sum-of-absolute-values is used.</p>
+<p>Only if the output is MNG, if filter-type is 7, the LOCO color
+transformation and adaptive filtering with
+minimum-sum-of-absolute-values are used.</p>
+<p>The default is quality is 75, which means nearly the best compression
+with adaptive filtering. The quality setting has no effect on the
+appearance of PNG and MNG images, since the compression is always
+lossless.</p>
+<p>For further information, see the PNG specification.</p>
+<p>When writing a JNG image with transparency, two quality values are
+required, one for the main image and one for the grayscale image that
+conveys the opacity channel. These are written as a single integer
+equal to the main image quality plus 1000 times the opacity quality.
+For example, if you want to use quality 75 for the main image and
+quality 90 to compress the opacity data, use -quality 90075.</p>
+<p>For the PNM family of formats (PNM, PGM, and PPM) specify a quality
+factor of zero in order to obtain the ASCII variant of the
+format. Note that -compress none used to be used to trigger ASCII
+output but provided the opposite result of what was expected as
+compared with other formats.</p>

+<p>The GraphicsMagick Wand C library provides a mid-level abstract C
+language programming interface for GraphicsMagick. It is originally
+based on the Wand API provided in ImageMagick as of August 2003.
+After August 2003, ImageMagick changed its license to one unusable by
+GraphicsMagick so this version of the Wand library is not completely
+in sync with the current ImageMagick version.</p>
+<p>The API is divided into a number of categories. While reading this
+documentation, please reference the <a class="reference external" href="../api/types.html">types</a> documentation as required:</p>
+<blockquote>
+<ul class="simple">
+<li><a class="reference external" href="drawing_wand.html">Drawing</a>: Wand vector drawing interfaces.</li>
+<li><a class="reference external" href="magick_wand.html">Magick</a>: Wand image processing interfaces</li>
+<li><a class="reference external" href="pixel_wand.html">Pixel</a>: Wand pixel access/update interfaces</li>
+</ul>
+</blockquote>
+<p>The following is a simple example program which (assuming the program
+name is <cite>rotate</cite>) is executed similar to <cite>rotate infile outfile</cite>. It
+reads from file <cite>infile</cite>, rotates the image 30 degrees using a black
+background, and writes the result to file <cite>outfile</cite>:</p>
+<pre class="literal-block">
+#include <stdlib.h>
+#include <stdio.h>
+#include <string.h>
+#include <wand/magick_wand.h>
+
+int main(int argc,char **argv)
+{
+ MagickWand *magick_wand;
+ MagickPassFail status = MagickPass;
+ const char *infile, *outfile;
+
+ if (argc != 3)
+ {
+ fprintf(stderr,"Usage: %s: infile outfile\n",argv[0]);
+ return 1;
+ }
+
+ infile=argv[1];
+ outfile=argv[2];
+
+ // Initialize GraphicsMagick API
+ InitializeMagick(*argv);
+
+ // Allocate Wand handle
+ magick_wand=NewMagickWand();
+
+ // Read input image file
+ if (status == MagickPass)
+ {
+ status = MagickReadImage(magick_wand,infile);
+ }
+
+ // Rotate image clockwise 30 degrees with black background
+ if (status == MagickPass)
+ {
+ PixelWand *background;
+ background=NewPixelWand();
+ PixelSetColor(background,"#000000");
+ status = MagickRotateImage(magick_wand,background,30);
+ DestroyPixelWand(background);
+ }
+
+ // Write output file
+ if (status == MagickPass)
+ {
+ status = MagickWriteImage(magick_wand,outfile);
+ }
+
+ // Diagnose any error
+ if (status != MagickPass)
+ {
+ char *description;
+ ExceptionType severity;
+
+ description=MagickGetException(magick_wand,&severity);
+ (void) fprintf(stderr,"%.1024s (severity %d)\n",
+ description,severity);
+ }
+
+ // Release Wand handle
+ DestroyMagickWand(magick_wand);
+
+ // Destroy GraphicsMagick API
+ DestroyMagick();
+
+ return (status == MagickPass ? 0 : 1);
+}
+</pre>
+<p>To compile on Unix, the command looks something like this:</p>
+<pre class="literal-block">
+gcc -o demo demo.c -O `GraphicsMagickWand-config --cppflags --ldflags --libs`
+</pre>
