2 * Updated the .so verison to 7.
6 * Added support for targetting builds on 64bit Windows and minimising
7 number of compiler warnings on Windows. Thanks to Ger Hobbelt for his
8 contributions to CreateDLL.
10 * Added new atttribute types:
11 M33dAttribute 3x3 double-precision matrix
12 M44dAttribute 4x4 double-precision matrix
13 V2d 2D double-precision vector
14 V3d 3D double-precision vector
16 * Bug fix: crash when reading a damaged image file (found
17 by Apple). An exception thrown inside the PIZ Huffman
18 decoder bypasses initialization of an array of pointers.
19 The uninitialized pointers are later passed to operator
22 * Bug fix: crash when reading a damaged image file (found by
23 Apple). Computing the size of input certain buffers may
24 overflow and wrap around to a small number, later causing
25 writes beyond the end of the buffer.
27 * In the "Technical Introduction" document, added
28 Premultiplied vs. Un-Premulitiplied Color section:
29 states explicitly that pixels with zero alpha and non-zero
30 RGB are allowed, points out that preserving such a pixel can
31 be a problem in application programs with un-premultiplied
32 internal image representations.
34 * exrenvmap improvements:
35 - New command line flags set the type of the input image to
36 latitude-longitude map or cube-face map, overriding the
37 envmap attribute in the input file header.
38 - Cube-face maps can now be assembled from or split into six
40 - Converting a cube-face map into a new cube-face map with
41 the same face size copies the image instead of resampling
42 it. This avoids blurring when a cube-face map is assembled
43 from or split into sub-images.
45 * Updated standard chromaticities in ImfAcesFile.cpp to match
46 final ACES (Academy Color Encoding Specification) document.
48 * Added worldToCamera and worldToNDC matrices to
49 ImfStandardAttributes.h (Florian Kainz)
50 * Increased the maximum length of attribute and channel names
51 from 31 to 255 characters. For files that do contain names
52 longer than 31 characters, a new LONG_NAMES_FLAG in the fil
53 version number is set. This flag causes older versions of
54 the IlmImf library (1.6.1 and earlier) to reject files with
55 long names. Without the flag, older library versions would
56 mis-interpret files with long names as broken.
58 * Reading luminance/chroma-encoded files via the RGBA
59 interface is faster: buffer padding avoids cache thrashing
60 for certain image sizes, redundant calls to saturation()
63 * Added "hemispherical blur" option to exrenvmap.
65 * Added experimental version of I/O classes for ACES file
66 format (restricted OpenEXR format with special primaries
67 and white point); added exr2aces file converter.
69 * Added new constructors to classes Imf::RgbaInputFile and
70 Imf::TiledRgbaInputFile. The new constructors have a
71 layerName parameter, which allows the caller to specify
72 which layer of a multi-layer or multi-view image will
75 * A number of member functions in classes Imf::Header,
76 Imf::ChannelList and Imf::FrameBuffer have parameters
77 of type "const char *". Added equivalent functions that
78 take "const std::string &" parameters.
80 * Added library support for Weta Digital multi-view images:
81 StringVector attribute type, multiView standard attribute
82 of type StringVector, utility functions related to grouping
83 channels into separate views.
84 (Peter Hillman, Florian Kainz)
87 * Removed Windows .suo files from distribution.
89 * Bug fix: crashes, memory leaks and file descriptor leaks
90 when reading damaged image files (some reported by Apple,
91 others found by running IlmImfFuzzTest).
93 * Added new IlmImfFuzzTest program to test how resilient the
94 IlmImf library is with respect broken input files: the program
95 first damages OpenEXR files by partially overwriting them with
96 random data; then it tries to read the damaged files. If all
97 goes well, the program doesn't crash.
101 * Bumped DSO version number to 6.0
103 * Added new standard attributes related to color rendering with
104 CTL (Color Transformation Language): renderingTransform,
105 lookModTransform and adoptedNeutral.
107 * Bug fix: for pixels with luminance near HALF_MIN, conversion
108 from RGB to luminance/chroma produces NaNs and infinities
110 * Bug fix: excessive desaturation of small details with certain
111 colors after repeatedly loading and saving luminance/chroma
112 encoded images with B44 compression.
114 * Added B44A compression, a minor variation of B44: in most cases,
115 the compression ratio is 2.28:1, the same as with B44, but in
116 uniform image areas where all pixels have the same value, the
117 compression ratio increases to 10.66:1. Uniform areas occur, for
118 example, in an image's alpha channel, which typically contains
119 large patches that are solid black or white, or in computer-
120 generated images with a black background.
122 * Added flag to configure.ac to enable or disable use of large
123 auto arrays in the IlmImf library. Default is "enable" for
124 Linux, "disable" for everything else.
125 (Darby Johnston, Florian Kainz)
126 * corrected version number on dso's (libtool) - now 5.0
127 * Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs
128 can link with static libraries properly
129 * eliminated some warning messages during install
133 * reorganized packaging of OpenEXR libraries to facilitate
134 integration with CTL. Now this library depends on the library
135 IlmBase. Some functionality has been moved into OpenEXR_Viewers,
136 which depends on two other libraries, CTL and OpenEXR_CTL.
137 Note: previously there were separate releases of
138 OpenEXR-related plugins for Renderman, Shake and Photoshop.
139 OpenEXR is supported natively by Rendermand and Photoshop, so
140 these plugins will not be supported for this or future
143 * New build scripts for Linux/Unix
145 * New Windows project files and build scripts
147 * float-to-half conversion now preserves the sign of float zeroes
148 and of floats that are so small that they become half zeroes.
150 * Bug fix: Imath::Frustum<T>::planes() returns incorrect planes
151 if the frustum is orthogonal.
153 * added new framesPerSecond optional standard attribute
156 - Rewrote function Imath::Quat<T>::setRotation() to make it
157 numerically more accurate, added confidence tests
158 - Rewrote function Imath::Quat<T>::slerp() using Don Hatch's
159 method, which is numerically more accurate, added confidence
161 - Rewrote functions Imath::closestPoints(), Imath::intersect(),
162 added confidence tests.
163 - Removed broken function Imath::nearestPointOnTriangle().
164 - Rewrote Imath::drand48(), Imath::lrand48(), etc. to make
165 them functionally identical with the Unix/Linux versions
166 of drand48(), lrand48() and friends.
167 - Replaced redundant definitions of Int64 in Imath and IlmImf
168 with a single definition in ImathInt64.h.
170 * exrdisplay: if the file's and the display's RGB chromaticities
171 differ, the pixels RGB values are transformed from the file's
172 to the display's RGB space.
174 * Added new lossy B44 compression method. HALF channels are
175 compressed with a fixed ratio of 2.28:1. UINT and FLOAT
176 channels are stored verbatim, without compression.
180 * Fixed the ReleaseDLL targets for Visual Studio 2003.
184 * Production release.
185 * Bug Fix: calling setFrameBuffer() for every scan line
186 while reading a tiled file through the scan line API
187 returns bad pixel data. (Paul Schneider, Florian Kainz)
190 * Fixed the ReleaseDLL targets for Visual Studio 2005.
191 (Nick Porcino, Drew Hess)
192 * Fixes/enhancements for createDLL.
196 * Removed openexr.spec file, it's out of date and broken to
199 * Support for Visual Studio 2005.
200 (Drew Hess, Nick Porcino)
201 * When compiling against OpenEXR headers on Windows, you
202 no longer need to define any HAVE_* or PLATFORM_*
203 macros in your projects. If you are using any OpenEXR
204 DLLs, however, you must define OPENEXR_DLL in your
205 project's preprocessor directives.
207 * Many fixes to the Windows VC7 build system.
208 (Drew Hess, Nick Porcino)
209 * Support for building universal binaries on OS X 10.4.
210 (Drew Hess, Paul Schneider)
211 * Minor configure.ac fix to accomodate OS X's automake.
213 * Removed CPU-specific optimizations from configure.ac,
214 autoconf's guess at the CPU type isn't very useful,
215 anyway. Closes #13429.
217 * Fixed quoting for tests in configure.ac. Closes #13428.
219 * Use host specification instead of target in configure.ac.
222 * Fix use of AC_ARG_ENABLE in configure.ac. Closes
225 * Removed workaround for OS X istream::read bug.
227 * Added pthread support to OpenEXR pkg-config file.
229 * Added -no-undefined to LDFLAGS and required libs to LIBADD
230 for library projects with other library dependencies, per
233 * HAVE_* macros are now defined in the OpenEXRConfig.h header
234 file instead of via compiler flags. There are a handful of
235 public headers which rely on the value of these macros,
236 and projects including these headers have previously needed
237 to define the same macros and values as used by OpenEXR's
238 'configure', which is bad form. Now 'configure' writes these
239 values to the OpenEXRConfig.h header file, which is included
240 by any OpenEXR source files that need these macros. This
241 method of specifying HAVE_* macros guarantees that projects
242 will get the proper settings without needing to add compile-
243 time flags to accomodate OpenEXR. Note that this isn't
244 implemented properly for Windows yet.
247 - No more support for IRIX or OSF1.
248 - No more explicit support for SunOS, because we have no way to
249 verify that it's working. I suspect that newish versions of
250 SunOS will just work out of the box, but let me know if not.
251 - No more PLATFORM_* macros (vestiges of the ILM internal build
252 system). PLATFORM_DARWIN_PPC is replaced by HAVE_DARWIN.
253 PLATFORM_REDHAT_IA32 (which was only used in IlmImfTest) is
254 replaced by HAVE_LINUX_PROCFS.
255 - OS X 10.4, which is the minimum version we're going to support
256 with this version, appears to have support for nrand48 and friends,
257 so no need to use the Imath-supplied version of them anymore.
259 * No more PLATFORM_WINDOWS or PLATFORM_WIN32, replace with
260 proper standard Windows macros. (Drew Hess)
261 * Remove support for gcc 2.95, no longer supported. (Drew Hess)
262 * Eliminate HAVE_IOS_BASE macro, OpenEXR now requires support for
263 ios_base. (Drew Hess)
264 * Eliminate HAVE_STL_LIMITS macro, OpenEXR now requires the ISO C++
265 <limits> header. (Drew Hess)
266 * Use double quote-style include dirctives for OpenEXR
267 includes. (Drew Hess)
268 * Added a document that gives an overview of the on-disk
269 layout of OpenEXR files (Florian Kainz)
270 * Added sections on layers and on memory-mapped file input
271 to the documentation. (Florian Kainz)
272 * Bug fix: reading an incomplete file causes a deadlock while
273 waiting on a semaphore. (Florian Kainz)
274 * Updated documentation (ReadingAndWritingImageFiles.sxw) and
275 sample code (IlmImfExamples):
276 Added a section about multi-threading, updated section on
277 thread-safety, changed documentation and sample code to use
278 readTiles()/writeTiles() instead of readTile()/writeTile()
279 where possible, mentioned that environment maps contain
280 redundant pixels, updated section on testing if a file is
283 * Multi-threading bug fixes (exceptions could be thrown
284 multiple times, some operations were not thread safe),
285 updated some comments, added comments, more multithreaded
288 * Added multi-threading support: multiple threads
289 cooperate to read or write a single OpenEXR file.
291 * Added operator== and operator!= to Imath::Frustum.
293 * Bug fix: Reading a PIZ-compressed file with an invalid
294 Huffman code table caused crashes by indexing off the
299 * Updated README to remove option for building with Visual C++ 6.0.
301 * Some older versions of gcc don't support a full iomanip
302 implemenation; check for this during configuration.
304 * Install PDF versions of documentation, remove old/out-of-date
305 HTML documentation. (Florian Kainz)
306 * Removed vc/vc6 directory; Visual C++ 6.0 is no longer
307 supported. (Drew Hess)
308 * Updated README.win32 with details of new build system.
309 (Florian Kainz, Drew Hess)
310 * New build system for Windows / Visual C++ 7 builds both
311 static libraries and DLLs.
313 * Removed Imath::TMatrix<T> and related classes, which are not
314 used anywhere in OpenEXR.
316 * Added minimal support for "image layers" to class Imf::ChannelList
318 * Added new isComplete() method to InputFile, TiledInputFile
319 etc., that checks if a file is complete or if any pixels
320 are missing (for example, because writing the file was
321 aborted prematurely).
323 * Exposed staticInitialize() function in ImfHeader.h in order
324 to allow thread-safe library initialization in multithreaded
327 * Added a new "time code" attribute
329 * exrmaketiled: when a MIPMAP_LEVELS or RIPMAP_LEVELS image
330 is produced, low-pass filtering takes samples outside the
331 image's data window. This requires extrapolating the image.
332 The user can now specify how the image is extrapolated
333 horizontally and vertically (image is surrounded by black /
334 outermost row of pixels repeats / entire image repeats /
335 entire image repeats, every other copy is a mirror image).
336 exrdisplay: added option to swap the top and botton half,
337 and the left and right half of an image, so that the image's
338 four corners end up in the center. This is useful for checking
339 the seams of wrap-around texture map images.
340 IlmImf library: Added new "wrapmodes" standard attribute
341 to indicate the extrapolation mode for MIPMAP_LEVELS and
342 RIPMAP_LEVELS images.
344 * Added a new "key code" attribute to identify motion picture
347 * Removed #include <Iex.h> from ImfAttribute.h, ImfHeader.h
348 and ImfXdr.h so that including header files such as
349 ImfInputFile.h no longer defines ASSERT and THROW macros,
350 which may conflict with similar macros defined by
351 application programs.
353 * Converted HTML documentation to OpenOffice format to
354 make maintaining the documents easier:
355 api.html -> ReadingAndWritingImageFiles.sxw
356 details.html -> TechnicalIntroduction.sxw
360 * exrenvmap and exrmaketiled use slightly less memory
362 * Added functions to IlmImf for quickly testing if a file
363 is an OpenEXR file, and whether the file is scan-line
364 based or tiled. (Florian Kainz)
365 * Added preview image examples to IlmImfExamples. Added
366 description of preview images and environment maps to
367 docs/api.html (Florian Kainz)
368 * Bug fix: PXR24 compression did not work properly for channels
371 * Made template <class T> become template <class S, class T> for
372 the transform(ObjectS, ObjectT) methods. This was done to allow
373 for differing templated objects to be passed in e.g. say a
374 Box<Vec3<S>> and a Matrix44<T>, where S=float and T=double.
375 (Jeff Yost, Arkell Rasiah)
376 * New method Matrix44::setTheMatrix(). Used for assigning a
377 M44f to a M44d. (Jeff Yost, Arkell Rasiah)
378 * Added convenience Color typedefs for half versions of Color3
379 and Color4. Note the Makefile.am for both Imath and ImathTest
380 have been updated with -I and/or -L pathing to Half.
381 (Max Chen, Arkell Rasiah)
382 * Methods equalWithAbsError() and equalWithRelError() are now
383 declared as const. (Colette Mullenhoff, Arkell Rasiah)
384 * Fixes for gcc34. Mainly typename/template/using/this syntax
385 correctness changes. (Nick Ramussen, Arkell Rasiah)
386 * Added Custom low-level file I/O examples to IlmImfExamples
387 and to the docs/api.html document. (Florian Kainz)
388 * Eliminated most warnings messages when OpenEXR is compiled
389 with Visual C++. The OpenEXR code uses lots of (intentional
390 and unintended) implicit type conversions. By default, Visual
391 C++ warns about almost all of them. Most implicit conversions
392 have been removed from the .h files, so that including them
393 should not generate warnings even at warning level 3. Most
394 .cpp files are now compiled with warning level 1.
398 * Production-ready release.
399 * Disable long double warnings on OS X. (Drew Hess)
400 * Add new source files to VC7 IlmImfDll target. (Drew Hess)
401 * Iex: change the way that APPEND_EXC and REPLACE_EXC modify
402 their what() string to work around an issue with Visual C++
403 7.1. (Florian Kainz, Nick Porcino)
404 * Bumped OpenEXR version to 1.2 and .so versions to 2.0.0 in
405 preparation for the release. (Drew Hess)
406 * Imath: fixed ImathTMatrix.h to work with gcc 3.4. (Drew Hess)
407 * Another quoting fix in openexr.m4. (Drew Hess)
408 * Quoting fix in acinclude.m4 for automake 1.8. (Brad Hards)
409 * Imath: put inline at beginning of declaration in ImathMatrix.h
410 to fix a warning. (Ken McGaugh)
411 * Imath: made Vec equalWith*Error () methods const.
412 * Cleaned up compile-time Win32 support. (Florian Kainz)
413 * Bug fix: Reading a particular broken PIZ-compressed file
414 caused crashes by indexing off the end of an array.
418 * Half: operator= and variants now return by reference rather
419 than by value. This brings half into conformance with
420 built-in types. (Drew Hess)
421 * Half: remove copy constructor, let compiler supply its
422 own. This improves performance up to 25% on some
423 expressions using half. (Drew Hess)
424 * configure: don't try to be fancy with CXXFLAGS, just use
425 what the user supplies or let configure choose a sensible
426 default if CXXFLAGS is not defined.
427 * IlmImf: fixed a bug in reading scanline files on big-endian
428 architectures. (Drew Hess)
429 * exrmaketiled: Added an option to select compression type.
431 * exrenvmap: Added an option to select compression type.
433 * exrdisplay: Added some new command-line options. (Florian Kainz)
434 * IlmImf: Added Pixar's new "slightly lossy" image compression
435 method. The new method, named PXR24, preserves HALF and
436 UINT data without loss, but FLOAT pixels are converted to
437 a 24-bit representation. PXR24 appears to compress
438 FLOAT depth buffers very well without losing much accuracy.
439 (Loren Carpenter, Florian Kainz)
440 * Changed top-level LICENSE file to allow for other copyright
441 holders for individual files.
442 * IlmImf: TILED FILE FORMAT CHANGE. TiledOutputFile was
443 incorrectly interleaving channels and scanlines before
444 passing pixel data to a compressor. The lossless compressors
445 still work, but lossy compressors do not. Fix the bug by
446 interleaving channels and scanlines in tiled files in the
447 same way as ScanLineOutputFile does. Programs compiled with
448 the new version of IlmImf cannot read tiled images produced
449 with version 1.1.0. (Florian Kainz)
450 * IlmImf: ImfXdr.h fix for 64-bit architectures. (Florian Kainz)
451 * IlmImf: OpenEXR now supports YCA (luminance/chroma/alpha)
452 images with subsampled chroma channels. When an image
453 is written with the RGBA convenience interface, selecting
454 WRITE_YCA instead of WRITE_RGBA causes the library to
455 convert the pixels to YCA format. If WRITE_Y is selected,
456 only luminance is stored in the file (for black and white
457 images). When an image file is read with the RGBA convenience
458 interface, YCA data are automatically converted back to RGBA.
460 * IlmImf: speed up reading tiled files as scan lines.
462 * Half: Fixed subtle bug in Half where signaling float NaNs
463 were being converted to inf in half. (Florian Kainz)
464 * gcc 3.3 compiler warning cleanups. (various)
465 * Imath: ImathEuler.h fixes for gcc 3.4. (Garrick Meeker)
468 * Added new targets to Visual C++ .NET 2003 project
469 for exrmaketiled, exrenvmap, exrmakepreview, and exrstdattr.
471 * A few assorted Win32 fixes for Imath. (Drew Hess)
472 * GNU autoconf builds now produce versioned libraries.
473 This release is 1:0:0. (Drew Hess)
474 * Fixes for Visual C++ .NET 2003. (Paul Schneider)
475 * Updated Visual C++ zlib project file to zlib 1.2.1.
477 * exrdisplay: Fixed fragment shader version. (Drew Hess)
478 * *Test: Fixed some compiler issues. (Drew Hess)
479 * Imath: Handle "restrict" keyword properly. (Drew Hess)
480 * IlmImfExamples: Updated to latest versions of example
481 source code, includes tiling and multi-res images.
483 * exrmakepreview: A new utility to create preview images.
485 * exrenvmap: A new utility to create OpenEXR environment
486 maps. (Florian Kainz)
487 * exrstdattr: A new utility to modify standard
488 attributes. (Florian Kainz)
489 * Updated exrheader to print level rounding mode and
490 preview image size. (Florian Kainz)
491 * Updated exrmaketiled to use level rounding mode.
493 * IlmImf: Changed the orientation of lat-long envmaps to
494 match typical panoramic camera setups. (Florian Kainz)
495 * IlmImf: Fixed a bug where partially-completed files with
496 DECREASING_Y could not be read. (Florian Kainz)
497 * IlmImf: Added support for selectable rounding mode (up/down)
498 when generating multiresolution files. (Florian Kainz)
499 * exrdisplay: Support for tiled images, mip/ripmaps, preview
500 images, and display windows. (Florian Kainz, Drew Hess)
501 * exrmaketiled: A new utility which generates tiled
502 versions of OpenEXR images. (Florian Kainz)
503 * IlmImf: Changed Imf::VERSION to Imf::EXR_VERSION to
504 work around problems with autoconf VERSION macro
505 conflict. (Drew Hess)
506 * exrheader: Support for tiles, mipmaps, environment
507 maps. (Florian Kainz)
508 * IlmImf: Environment map support. (Florian Kainz)
509 * IlmImf: Abstracted stream I/O support. (Florian Kainz)
510 * IlmImf: Support for tiled and mip/ripmapped files;
511 requires new file format. (Wojciech Jarosz, Florian Kainz)
512 * Imath: TMatrix*, generic 2D matricies and algorithms.
514 * Imath: major quaternions cleanup. (Cary Phillips)
515 * Imath: added GLBegin, GLPushAttrib, GLPushMatrix objects
516 for automatic cleanup on exceptions. (Cary Phillips)
517 * Imath: removed implicit scalar->vector promotions and vector
518 comparisons. (Nick Rasmussen)
521 * Fixed a typo in one of the IlmImfTest tests. (Paul Schneider)
522 * Fixed a bug in exrdisplay that causes the image to display
523 as all black if there's a NaN or infinity in an OpenEXR
524 image. (Florian Kainz)
525 * Updated exrheader per recent changes to IlmImf library.
527 * Changed an errant float to a T in ImathFrame.h nextFrame().
529 * Support for new "optional standard" attributes
530 (chromaticities, luminance, comments, etc.).
531 (Florian Kainz, Greg Ward, Joseph Goldstone)
532 * Fixed a buffer overrun in ImfOpaqueAttribute. (Paul Schneider)
533 * Added new function, isImfMagic (). (Florian Kainz)
536 * Added README.win32 to disted files.
537 * Fixed OpenEXR.pc.in pkg-config file, OpenEXR now works
539 * Random fixes to readme files for new release.
540 * Fixed openexr.m4, now looks in /usr by default.
541 * Added Visual Studio .NET 2003 "solution."
542 * Fixes for Visual Studio .NET 2003 w/ Microsoft C++ compiler.
544 * Random Imath fixes and enhancements. Note that
545 extractSHRT now takes an additional optional
546 argument, see ImathMatrixAlgo.h for details. (Various)
547 * Added Wojciech Jarosz to AUTHORS file.
548 * Added test cases for uncompressed case, preview images,
549 frame buffer type conversion. (Wojciech Jarosz,
551 * Fix a bug in IlmImf where uncompressed data doesn't get
552 read/written correctly. (Wojciech Jarosz)
553 * Added support for preview images and preview image
554 attributes (thumbnail images) in IlmImf. (Florian Kainz)
555 * Added support for automatic frame buffer type conversion
556 in IlmImf. (Florian Kainz)
557 * Cleaned up some compile-time checks.
558 * Added HalfTest unit tests.
559 * [exrdisplay] Download half framebuffer to texture memory
560 instead of converting to float first. Requires latest
564 * Fixed IlmImf.dll to use static runtime libs (Andreas).
565 * Added exrheader project to Visual Studio 6.0 workspace.
566 * Added some example code showing how to use the IlmImf library.
568 * Use DLL runtime libs for Win32 libraries rather than static
570 * Add an exrdisplay_fragshader project to the Visual Studio 6.0
571 workspace to enable fragment shaders in Win32.
572 * Add an IlmImfDll project to the Visual Studio 6.0 workspace.
573 * In Win32, export the ImfCRgbaFile C interface via a DLL so
574 that Visual C++ 6.0 users can link against an Intel-compiled
575 IlmImf. (Andreas Kahler)
576 * Use auto_ptr in ImfAutoArray on Win32, it doesn't like large
578 * Performance improvements in PIZ decoding, between
579 20 and 60% speedup on Athlon and Pentium 4 systems.
581 * Updated the README with various information, made
582 some cosmetic changes for readability.
583 * Added fragment shader support to exrdisplay.
584 * Bumped the version to 1.0.5 in prep for release.
585 * Updated README and README.OSX to talk about CodeWarrior
587 * Incorporated Rodrigo Damazio's patch for an openexr.m4
588 macro file and an openexr.spec file for building RPMs.
589 * Small change in ImfAttribute.h to make IlmImf compile with gcc 2.95.
590 * Updated ImfDoubleAttribute.h for Codewarrior on MacOS.
591 * Added exrheader utility.
592 * Update to AUTHORS file.
593 * Added a README.win32 file.
594 * Added project files for Visual Studio 6.0.
595 * Initial Win32 port. Requires Visual Studio 6.0 and Intel C++
596 compiler version 7.0.
597 * Added new intersectT method in ImathSphere.h
598 * Fixed some bugs in ImathQuat.h
599 * Proper use of fltk-config to get platform-specific FLTK
600 compile- and link-time flags.
601 * exrdisplay uses Imath::Math<T>::pow instead of powf now.
602 powf is not availble on all platforms.
603 * Roll OS X "hack" into the source until Apple fixes their
604 istream implementation.
607 * OpenEXR is now covered by a modified BSD license. See LICENSE
612 * OpenEXR is now in sf.net CVS.
613 * Imf::Xdr namespace cleanups.
614 * Some IlmImfTest cleanups for OS X.
615 * Use .cpp extension in exrdisplay sources.
617 * Make IlmImf compile with Metrowerks Codewarrior.
618 * Change large automatic stacks in ImfHuf.C to auto_ptrs allocated
619 off the heap. MacOS X default stack size isn't large enough.
620 * std::ios fix for MacOS X in ImfInputFile.C.
621 * Added new FP predecessor/successor functions to Imath, added
623 * Fixed a bug in Imath::extractSHRT for 3x3 matricies when
624 exactly one of the original scaling factors is negative, updated
625 ImathTest to check this case.
626 * Install include files when 'make install' is run.
627 * exrdisplay requires fltk 1.1+ now in an effort to support
628 a MacOS X display program (fltk 1.1 runs on OS X), though this
630 * renamed configure.in to configure.ac
631 * Removed some tests from IexTest that are no longer used.
632 * Removed ImfHalfXdr.h, it's not used anymore.
633 * Revamped the autoconf system, added some compile-time
634 optimizations, a pkgconfig target, and some maintainer-specific
639 * More OS X fixes in Imath, IlmImf and IlmImfTest.
641 * Fixed a rotation bug in Imath
645 * Used autoconf 2.53 and automake 1.6 to generate build environment.
646 * Makefile.am cleanups.
648 * removed images directory (now distributed separately).
652 * first official release.
653 * added some high-level documentation, removed the old OpenEXR.html
655 * fixed a few nagging build problems.
656 * bumped IMV_VERSION_NUMBER to 2
660 * added exrdisplay viewer application.
661 * cleanup _data in Imf::InputFile and Imf::OutputFile constructors.
662 * removed old ILM copyright notices.
