        Fix NULL pointer dereference in TIFFPrintDirectory (bugzilla 2778/CVE-2018-7456)

        See merge request libtiff/libtiff!27

2018-04-11  Hugo Lefeuvre  <hle@debian.org>

        Fix NULL pointer dereference in TIFFPrintDirectory.
        The TIFFPrintDirectory function relies on the following assumptions,
        supposed to be guaranteed by the specification:

        (a) A Transfer Function field is only present if the TIFF file has
            photometric type < 3.

        (b) If SamplesPerPixel > Color Channels, then the ExtraSamples field
            has count SamplesPerPixel - (Color Channels) and contains
            information about supplementary channels.

        While respect of (a) and (b) are essential for the well functioning of
        TIFFPrintDirectory, no checks are realized neither by the callee nor
        by TIFFPrintDirectory itself. Hence, following scenarios might happen
        and trigger the NULL pointer dereference:

        (1) TIFF File of photometric type 4 or more has illegal Transfer
            Function field.

        (2) TIFF File has photometric type 3 or less and defines a
            SamplesPerPixel field such that SamplesPerPixel > Color Channels
            without defining all extra samples in the ExtraSamples fields.

        In this patch, we address both issues with respect of the following
        principles:

        (A) In the case of (1), the defined transfer table should be printed
            safely even if it isn't 'legal'. This allows us to avoid expensive
            checks in TIFFPrintDirectory. Also, it is quite possible that
            an alternative photometric type would be developed (not part of the
            standard) and would allow definition of Transfer Table. We want
            libtiff to be able to handle this scenario out of the box.

        (B) In the case of (2), the transfer table should be printed at its
            right size, that is if TIFF file has photometric type Palette
            then the transfer table should have one row and not three, even
            if two extra samples are declared.

        In order to fulfill (A) we simply add a new 'i < 3' end condition to
        the broken TIFFPrintDirectory loop. This makes sure that in any case
        where (b) would be respected but not (a), everything stays fine.

        (B) is fulfilled by the loop condition
        'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as
        long as (b) is respected.

        Naturally, we also make sure (b) is respected. This is done in the
        TIFFReadDirectory function by making sure any non-color channel is
        counted in ExtraSamples.

        This commit addresses CVE-2018-7456.

2018-02-12  Nathan Baker  <nathanb@lenovo-chrome.com>

        Fix for bug 2772.
        It is possible to craft a TIFF document where the IFD list is circular,
        leading to an infinite loop while traversing the chain. The libtiff
        directory reader has a failsafe that will break out of this loop after
        reading 65535 directory entries, but it will continue processing,
        consuming time and resources to process what is essentially a bogus TIFF
        document.

        This change fixes the above behavior by breaking out of processing when
        a TIFF document has >= 65535 directories and terminating with an error.

        Add libzstd to gitlab-ci.

2017-12-21  Even Rouault  <even.rouault@spatialys.com>

        Add ZSTD compression codec.
        From https://github.com/facebook/zstd
        "Zstandard, or zstd as short version, is a fast lossless compression
        algorithm, targeting real-time compression scenarios at zlib-level
        and better compression ratios. It's backed by a very fast entropy stage,
        provided by Huff0 and FSE library."

        We require libzstd >= 1.0.0 so as to be able to use streaming compression
        and decompression methods.

        The default compression level we have selected is 9 (range goes from 1 to 22),
        which experimentally offers equivalent or better compression ratio than
        the default deflate/ZIP level of 6, and much faster compression.

        For example on a 6600x4400 16bit image, tiffcp -c zip runs in 10.7 seconds,
        while tiffcp -c zstd runs in 5.3 seconds. Decompression time for zip is
        840 ms, and for zstd 650 ms. File size is 42735936 for zip, and
        42586822 for zstd. Similar findings on other images.

        On a 25894x16701 16bit image,

        tiff2pdf: Fix apparent incorrect type for transfer table.
        The standard says the transfer table contains unsigned 16 bit values,
        I have no idea why we refer to them as floats.

2017-12-10  Brian May  <brian@linuxpenguins.xyz>

        tiff2pdf: Fix CVE-2017-9935.
        Fix for http://bugzilla.maptools.org/show_bug.cgi?id=2704

        This vulnerability - at least for the supplied test case - is because we
        assume that a tiff will only have one transfer function that is the same
        for all pages. This is not required by the TIFF standards.

        We than read the transfer function for every page.  Depending on the
        transfer function, we allocate either 2 or 4 bytes to the XREF buffer.
        We allocate this memory after we read in the transfer function for the
        page.

        For the first exploit - POC1, this file has 3 pages. For the first page
        we allocate 2 extra extra XREF entries. Then for the next page 2 more
        entries. Then for the last page the transfer function changes and we
        allocate 4 more entries.

        When we read the file into memory, we assume we have 4 bytes extra for
        each and every page (as per the last transfer function we read). Which
        is not correct, we only have 2 bytes extra for the first 2 pages. As a
        result, we end up writing past the end of the buffer.

        There are also some related issues that this also fixes. For example,
        TIFFGetField can return uninitalized pointer values, and the logic to
        detect a N=3 vs N=1 transfer function seemed rather strange.

        It is also strange that we declare the transfer functions to be of type
        float, when the standard says they are unsigned 16 bit values. This is
        fixed in another patch.

        This patch will check to ensure that the N value for every transfer
        function is the same for every page. If this changes, we abort with an
        error. In theory, we should perhaps check that the transfer function
        itself is identical for every page, however we don't do that due to the
        confusion of the type of the data in the transfer function.

        to behave differently depending on whether the codec is enabled or not, and
        thus can avoid stack based buffer overflows in a number of TIFF utilities
        such as tiffsplit, tiffcmp, thumbnail, etc.

2015-08-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * CMakeLists.txt, libtiff/test/Makefile.am: Applied patches by
        Roger Leigh (via tiff mailing list on 2015-08-31.

        CMake reads all version information directly from configure.ac to
        avoid duplication of values.  This basically greps over the file
        for the LIBTIFF_* variables, then translates them to the form
        needed for cmake. This includes the release version and libtool
        shared library version information.

        Make shared/static library building configurable.  Currently it
        always builds shared libraries, with static libs having a _static
        suffix (copying zlib, but it means it's got a non-standard name).
        CMake has a -DBUILD_SHARED_LIBS=ON|OFF option to select one or the
        other, which is now used instead.  There's now a single "tiff"
        target to build either shared or static as required, and all the
        tests and tools are linked with this. Note: the Windows tests fail
        when linked with a static libtiff (says: libtiff.dll not found).
        Not really a regression since this was not tested up to this
        point, and it's likely the unit tests haven't (ever?) been run on
        Windows with a static libtiff, so there's some additional
        portability issue here to address.  Works fine on UNIX systems,
        and fine on Windows with the default to build a DLL.

        Add a missing file which wasn't being distributed, causing unit
        tests to fail.  Note that "find . -name '*.cmake'" lists all the
        CMake files which need distributing in addition to all the
        CMakeLists.txt files (which now are distributed).

2015-08-31  Even Rouault <even.rouault at spatialys.com>

2015-08-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tiffiop.h: For MinGW comiles, make sure that build
        supports necessary __MSVCRT_VERSION__ (at least at least 0x800).
        Otherwise large files can not be supported for POSIX-style I/O.

        * libtiff/tiffiop.h: First cut at supporting large files under

        only works if the Windows CDK is new enough to support the APIs
        used (Visual C++ 2005 or later).  Support for large files is not
        actually tested yet.

        description.

        * libtiff/tiffconf.vc.h: Build fixes based on testing.

        * libtiff/tif_config.vc.h: Build fixes based on testing.

        export for it.

2015-06-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_config.vc.h: Make adjustments to match the new
        definitions that configure produces, including for WIN64.  Still
        needs to be tested.

        * configure.ac: For 64-bit MinGW, fix SSIZE_FORMAT formatting
        specifier.  64-bit MinGW supports 'long long' but support for
        'lld' is not assured by the run-time DLLs and so GCC warns.
        Add TIFF_SIZE_T and TIFF_SIZE_FORMAT to provide a type definition
        and printf format specifier to deal with printing values of
        'size_t' type.  In particular, this was necessary for WIN64.
        Added a configure test for if the system headers provide 'optarg'
        (normal case) and block out the many explicit 'extern' statements
        in the utilities.  This was found to be necessary under Windows
        when getopt is in a DLL and the symbols are already imported with
        dllimport via standard header files.

        * test/raw_decode.c (XMD_H): Avoid conflicting typedefs for INT32
        and boolean in MinGW build due to including jpeglib.h.

        * test/rewrite_tag.c (main): Fix problem with location of variable
        declaration.

        * libtiff/libtiff.def: Added exports for TIFFGetConfiguredCODECs,
        TIFFReadRGBAImageOriented, TIFFSetCompressionScheme,
        TIFFSwabArrayOfTriples, TIFFVGetFieldDefaulted, _TIFFCheckRealloc,
        TIFFRasterScanline, TIFFSetErrorHandlerExt,
        TIFFSetWarningHandlerExt, TIFFNumberOfDirectories,
        TIFFCreateCustomDirectory, TIFFCreateEXIFDirectory,
        TIFFWriteCustomDirectory, _TIFFRewriteField as recommended by
        Roger Leigh and justified by use in libtiff tests, documentation,
        and changelog notes.  Also sorted symbol list and removed
        duplicate entries.

        * tools/tiffcp.c: fix crash when converting YCbCr JPEG-compressed to none.
        Based on patch by Tomasz Buchert (http://bugzilla.maptools.org/show_bug.cgi?id=2480)
        Description: fix for Debian bug #741451
        tiffcp crashes when converting JPEG-encoded TIFF to a different
        encoding (like none or lzw). For example this will probably fail:
        tiffcp -c none jpeg_encoded_file.tif output.tif
        The reason is that when the input file contains JPEG data,
        the tiffcp code forces conversion to RGB space. However,
        the output normally inherits YCbCr subsampling parameters
        from the input, which leads to a smaller working buffer
        than necessary. The buffer is subsequently overrun inside
        cpStripToTile() (called from writeBufferToContigTiles).
        Note that the resulting TIFF file would be scrambled even
        if tiffcp wouldn't crash, since the output file would contain
        RGB data intepreted as subsampled YCbCr values.
        This patch fixes the problem by forcing RGB space on the output
        TIF if the input is JPEG-encoded and output is *not* JPEG-encoded.

        Also add explicit removal of Huffman tables when jpegtablesmode has the

        * libtiff/tif_dirread.c (TIFFReadDirEntryOutputErr): Incorrect
        count for tag should be a warning rather than an error since
        errors terminate processing.

        * tools/tiff2rgba.c (]): Fixed tiff2rgba usage message in that zip

        be defective, then set it to zero before returning error in order
        to terminate processing of truncated TIFF.  Issue found and fix
        suggested by Richard Nolde.

2013-05-02  Tom Lane  <tgl@sss.pgh.pa.us>

        * tools/tiff2pdf.c: Rewrite JPEG marker parsing in
        t2p_process_jpeg_strip to be at least marginally competent.  The
        approach is still fundamentally flawed, but at least now it won't
        stomp all over memory when given bogus input.  Fixes CVE-2013-1960.

2013-05-02  Tom Lane  <tgl@sss.pgh.pa.us>

        * contrib/dbs/xtiff/xtiff.c, libtiff/tif_codec.c,

        tools/tiff2pdf.c, tools/tiff2ps.c, tools/tiffcrop.c,
        tools/tiffdither.c: Enlarge some fixed-size buffers that weren't
        large enough, and eliminate substantially all uses of sprintf(buf,
        ...)  in favor of using snprintf(buf, sizeof(buf), ...), so as to
        protect against overflow of fixed-size buffers.  This responds in
        particular to CVE-2013-1961 concerning overflow in tiff2pdf.c's
        t2p_write_pdf_page(), but in general it seems like a good idea to
        deprecate use of sprintf().

2013-03-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * test/raw_decode.c: Relax raw_decode's pixel-value checks so that
        it will pass with more versions of libjpeg.  (There are at least
        three in active use now, and JPEG_LIB_VERSION doesn't tell us
        enough to uniquely identify expected results.)

        * libtiff{tiff.h, tif_print.c, tif_dirinfo.c, tif_dirread.c}: Add
        some TIFF/FX support in libtiff.  Add the tag definitions to
        tiff.h.  Add the related TIFF field definitions to tif_dirinfo.c,
        and also fixes an error in a comment.  Adds the photometric values
        to tif_print.c, and fixes a bug.  These changes are by Steve
        Underwood.

2012-08-13  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_write.c: Fix bug rewriting image tiles in a

2012-08-02  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_dirread.c: report error in case of mismatch value
        counts for tags (ie. DotRange).

2012-07-26  Tom Lane  <tgl@sss.pgh.pa.us>

        * libtiff/{tiffio.h, tif_dirinfo.c, libtiff.def}: Add six new
        functions TIFFFieldTag(), TIFFFieldName(), TIFFFieldDataType(),
        TIFFFieldPassCount(), TIFFFieldReadCount(), TIFFFieldWriteCount()
        as external accessors for the opaque type TIFFField.

        * tools/tiffset.c: Make tiffset use the above functions instead of
        relying on library private headers.

2012-07-19  Tom Lane  <tgl@sss.pgh.pa.us>

        * tools/tiff2pdf.c: Fix two places where t2p_error didn't get set
        after a malloc failure.  No crash risk AFAICS, but the program
        might not report exit code 1 as desired.  h/t mancha@mac.hush.com

2012-07-18  Tom Lane  <tgl@sss.pgh.pa.us>

        * tools/tiff2pdf.c: Fail when TIFFSetDirectory() fails.  This
        prevents core dumps or perhaps even arbitrary code execution when
        processing a corrupt input file (CVE-2012-3401).

2012-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * test/raw_decode.c (main): Test fixes to work with IJG JPEG 7+.
        IJG JPEG 7+ uses a different upsampling algorithm which produces
        different numeric results.

        * libtiff/tif_jpeg.c (JPEGPreDecode): Patch from Even Rouault to
        work with IJG JPEG 7+.

2012-07-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * test/raw_decode.c: Add changes so that test can run with build
        directory outside of source directory.

2012-07-02  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_jpeg.c: Fix handling when writing RGBA jpeg compressed

2012-06-20  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_fax3.c: fix memory initialization of runs, only
        partly done.

        * libtiff/tif_pixarlog.c: Make sure tbuf is large enough for one
        full "stride" past the end.

2012-06-19  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_packbits.c: fix read past end of data buffer.

        * tools/tif2pdf.c, tools/tifdump.c: avoid unitialized variable
        warnings with clang.

2012-06-15  Tom Lane  <tgl@sss.pgh.pa.us>

        * tools/tiff2pdf.c: Defend against integer overflows while
        calculating required buffer sizes (CVE-2012-2113).

2012-06-12  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_print.c: Be careful about printing corrupt inknames.

        * libtiff/tif_fax3.c: Ensure runs array is initialized to zeros.

2012-06-07  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_print.c: avoid pretty printing other fields when
        we don't have the proper amount and type of data or if the field
        is actually autodefined.

2012-06-05  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_tile.c, libtiff/tif_strip.c: Ensure that illegal
        ycbcrsubsampling values result in a runtime error, not just an
        assertion.

        * tests/custom_dir.c: Add testing of EXIF and custom directory
        reading and writing.

        * libtiff/tif_dir.c, libtiff/tiffio.h: Add TIFFCreateCustomDirectory()
        and TIFFCreateEXIFDirectory() functions.

        * libtiff/tif_dir.c, tif_print.c : Remove FIELD_CUSTOM handling for
        PAGENUMBER, HALFTONEHINTS, and YCBCRSUBSAMPLING.  Implement DOTRANGE
        differently.  This is to avoid using special TIFFGetField/TIFFSetField
        rules for these fields in non-image directories (like EXIF).

2012-06-04  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_jpeg.c: Remove code for fixing up h_sampling and v_sampling
        in JPEGPreDecode().  If a fixup will be done it needs to be done sooner
        in JPEGFixupTagsSubsampling() or else buffer sized may be wrong.

2012-06-01  Frank Warmerdam  <warmerdam@google.com>

        * tools/tiffinfo.c: Do not try to read image data in EXIF directories.

        * libtiff/tif_getimage.c: added support for _SEPARATED CMYK images.
        http://bugzilla.maptools.org/show_bug.cgi?id=2379

        * libtiff/tif_unix.c: use strerror() to return a more specific error message
        on failed open.
        http://bugzilla.maptools.org/show_bug.cgi?id=2341

        * libtiff/tif_jpeg.c: Fix JPEGDecodeRaw() bugs.
        http://bugzilla.maptools.org/show_bug.cgi?id=2386

        * tests/decode_raw.c, tests/images/quad-tile.jpg.tiff: add limited support
        for testing jpeg in tiff image decoding including the "raw" decode interface.

2012-05-31  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_jpeg.c: avoid overrunning the end of the output buffer in
        JPEGDecodeRaw() - mostly likely to occur when there is confusion about
        sampling values.

        * libtiff/tif_read.c: Make sure tif_rawdatasize is cleared when tif_rawdata is freed.

        * libtiff/tif_getimage.c: Add support for greyscale+alpha c/o Jérémie Laval.
        http://bugzilla.maptools.org/show_bug.cgi?id=2398

2012-05-29  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_dir.c: avoid using specific set/get logic to process fields in custom directories,
        like EXIF directories.  This fixes problems like a tag "320" existing in a custom directory getting
        processed as if it were a colormap when it isn't really.  Damn the wide variety of argument formulations
        to get/set functions for different tags!

        * libtiff/tif_dir.c: Ensure that we keep track of when tif_rawdata
        is a pointer into an mmap()ed file via TIFF_BUFFERMMAP flag.

2012-05-24  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_pixarlog.c: Allocate working buffer one word larger since we "forward
        accumulate" and overwrite the end by one word in at least some cases.

2012-05-23  Frank Warmerdam  <warmerdam@google.com>

        * libtiff/tif_pixarlog.c: avoid accessing out of the lookup arrays for out of range inputs.

        * tools/tiffinfo.c: initialize h=0 to avoid undefined variable for degenerate files.

        * libtiff/tif_ojpeg.c: if OJPEGWriteHeader() fails once do not bother trying again on
        the same image.

        * libtiff/tif_ojpeg.c: make things more resilient in the face of files without
        stripbytecounts or stripoffsets or where loading these fails.

        * libtiff/tif_print.c: be careful about whether min/max values are singular
        or one per sample.

        * libtiff/tif_print.c: Avoid confusion about count size when printing custom fields.
        May affect things like ISOSpeedRatings.

        * libtiff/tif_dir.c: avoid one byte past end of ink names reading
        in some cases.

2012-05-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * man/TIFFGetField.3tiff: Correct the 'count' field type in the
        example for how to retrieve the value of unsupported tags.

2012-03-30  Frank Warmerdam  <warmerdam@google.com>

        * tif_getimage.c: Fix size overflow (zdi-can-1221,CVE-2012-1173)
        care of Tom Lane @ Red Hat.

2012-02-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff 4.0.1 released.

        * Update automake used to 1.11.3.

        * libtiff/tiffio.h: Use double-underbar syntax in GCC printf
        attribute specification to lessen the risk of accidental macro
        substitution.  Patch from Vincent Torri.

2012-01-31  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dir.c, libtiff/tif_dirread.c: Extra caution around
        assumption tag fetching is always successful.

        * libtiff/tif_jpeg.c: Extra caution for case where sp is NULL.

2012-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Add support for using library symbol versioning on
        ELF systems with the GNU linker.  Support is enabled via
        --enable-ld-version-script.  Disabled by default for now until
        there is a decision for how to deploy a libtiff with versioned
        symbols after libtiff 4.0.0 was already released.

2011-12-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_win32.c: Eliminate some minor 64-bit warnings in

        tif_win32.c.  Patch by Edward Lam.

        * configure.ac: Add libtiff private dependency on -llzma for
        pkg-config.  Patch by Mark Brand.
        Updated Automake to 1.11.2.

2011-12-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff 4.0.0 released.

2011-12-08  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirread.c, libtiff/tif_read.c: more cautious checking
        of _TIFFFillStriles() results (#gdal 4372)

2011-12-07  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirread.c: fixes to deal with invalid files where
        _TIFFFillStriles() fails, and we try to chop up strips (gdal #4372)

        * libtiff/tif_dirread.c: fix error reporting when there is no
        tag information struct and name (gdal #4373)

2011-10-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Update GNU libtool to 2.4.2.

        * tools/tiffsplit.c (tiffcp): TIFFGetField count field should be
        uint32 type for TIFFTAG_JPEGTABLES.  Patch by Christophe
        Deroulers.

2011-06-21  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/libtiff.def: Restore TIFFMergeFieldInfo.

2011-05-31  Jim Meyering  <meyering@redhat.com>

        * libtiff/tif_dirread.c (TIFFFetchStripThing): Free "data" also
        upon failure to allocate "resizeddata".
        * tools/tiff2ps.c (PSDataBW): Zero buffer *after* checking for
        allocation failure, not before.
        * libtiff/tif_ojpeg.c: plug leaks on OJPEG read failure path
        * tools/rgb2ycbcr.c (cvtRaster): unchecked malloc
        * libtiff/tif_jpeg.c, tools/tiff2pdf.c, tools/tiff2ps.c: mark
        NULL-deref and possible overflow
        * tools/tiff2pdf.c: remove decl+set of set-but-not-used local, "written"
        * libtiff/tif_jpeg.c (JPEGInitializeLibJPEG): Remove declaration
        and set of otherwise unused local, data_is_empty.
        * libtiff/tif_jpeg.c (JPEGDecodeRaw) [JPEG_LIB_MK1_OR_12BIT]:
        Diagnose out-of-memory failure and return 0 rather than
        dereferencing NULL.

2011-05-24  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirread.c: produce special error message for zero tag
        directories instead of error out on the malloc(0) failure.

2011-05-16  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirinfo.c: Restore TIFFMergeFieldInfo() and
        related declarations as they are in active use by libraries
        such as libgeotiff, and work just fine.  (#2315)

2011-04-20  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirinfo.c,tiffio.h: Remove the obsolete
        TIFFMergeFieldInfo/TIFFFindFieldInfo/TIFFFindFieldInfoByName API.
        http://bugzilla.maptools.org/show_bug.cgi?id=2315

        * libtiff/libtiff.def: add some missing (64bit) APIs.
        http://bugzilla.maptools.org/show_bug.cgi?id=2316

2011-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff 4.0.0beta7 released.

2011-04-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Should use AC_CANONICAL_HOST since host specifies
        the run-time target whereas target is used to specify the final
        output target if the package is a build tool (like a compiler),
        which libtiff is not.  Resolves libtiff bug 2307 "Use
        AC_CANONICAL_HOST macro".

2011-04-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Support configuring TIFF_INT64_FORMAT and
        TIFF_UINT64_FORMAT appropriately for MinGW32.

        * tools/tiffdump.c (ReadDirectory): MinGW32 needs to use WIN32
        printf conventions for 64-bit types because it uses the WIN32 CRT.

        * libtiff/{tif_dumpmode.c,tif_luv.c,tif_lzw.c,tif_print.c,
        tif_read.c,tif_strip.c,tif_thunder.c}: MinGW32 needs to use WIN32
        printf conventions for 64-bit types because it uses the WIN32 CRT.

        * tools/tiff2pdf.c (t2p_write_pdf_string): Fix printf syntax not
        understood by WIN32 CRT.

        * libtiff/tif_ojpeg.c: Fixes to compile with MinGW32 GCC.

        * tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since
        it is much more portable.  Tmpfile is included in ISO/IEC
        9899:1990 and the WIN32 CRT.

2011-03-26  Frank Warmerdam  <warmerdam@pobox.com>

        * tools/tiffset.c: add -d and -sd switches to allow operation on
        a particular directory, not just the first (jef).

2011-03-21  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_thunder.c: Correct potential buffer overflow with
        thunder encoded files with wrong bitspersample set.  The libtiff
        development team would like to thank Marin Barbella and TippingPoint's
        Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004,
        CVE-2011-1167).

        * libtiff/tif_fax3.h: Fix to last change allowing zero length
        runs at the start of a scanline - needed for legal cases.

2011-03-02  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
        a move left.  Without this, a malicious input file can generate an
        indefinitely large series of runs without a0 ever reaching the right
        margin, thus overrunning our buffer of run lengths.  Per CVE-2011-0192.
        This is a modified version of a patch proposed by Drew Yao of Apple
        Product Security.  It adds an unexpected() report, and disallows the
        equality case, since emitting a run without increasing a0 still allows
        buffer overrun.

2011-02-23  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: avoid divide by zero in degenerate case (#2296)

        * tools/tiff2rgba.c: close source file on error to make leak
        detection easier.

        * libtiff/tif_getimage.c: avoid leaks if TIFFRGBAImageBegin() fails.

2011-02-22  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_lzma.c: Maintain tif_rawcc/tif_rawcp (CHUNKY_STRING_READ
        _SUPPORT)

2011-02-18  Frank Warmerdam  <warmerdam@pobox.com>

        * configure.ac, configure: Added support for --enable-chunky-strip-read
        configure option to enable the experimental feature from a couple
        months ago for reading big strips in chunks.

        * configure.ac, tif_read.c, tif_readdir.c, tif_dir.h, tiffiop.h,
        tif_write.c, tif_print.c, tif_jpeg.c, tif_dirwrite.c, tif_write.c:
        Implement optional support for deferring the load of strip/tile
        offset and size tags for optimized scanning of directories.  Enabled
        with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD
        #define in tif_config.h).

2011-02-11  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_print.c: remove unused variable.

2011-02-09  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_win32.c: avoid error/warning buffer overrun problem
        with non-console (popup message) builds on win32.

        tif_print.c, tiff.h, tiffiop.h} : Added support for
        TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE to have different
        values for each sample. Presents the min/max of all samples by default for
        compatibility. TIFFSetField/TIFFGetField can be made to handle those tags
        as arrays by changing the new TIFFTAG_PERSAMPLE pseudo tag.

2011-01-06  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_pixarlog.c: Note that tif_rawcc/tif_rawcp are not
        maintained.

        * libtiff/tif_zip.c: Maintain tif_rawcc/tif_rawcp when decoding
        for CHUNKY_STRIP_READ_SUPPORT.

        * libtiff/tif_jpeg.c: ensure that rawcc and rawcp are maintained
        during JPEGPreDecode and JPEGDecode calls.
        * libtiff/tif_read.c: larger read ahead for CHUNKY_STRIP_READ_SUPPORT,
        as compression formats like JPEG keep 16 lines interleaved in a sense
        and might need to touch quite a bit of data.

2010-07-07  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_dirread.c: Really reset the tag count in CheckDirCount()
        to expected value as the warning message suggests. As per bug
        http://bugzilla.maptools.org/show_bug.cgi?id=1963

2010-07-06  Andrey Kiselev  <dron@ak4719.spb.edu>

        TIFFTAG_HALFTONEHINTS, TIFFTAG_YCBCRSUBSAMPLING, TIFFTAG_DOTRANGE
        which should be set by value.

        * libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag()
        and _TIFFFieldWithName() if the tag is not found in the tag table.
        This should be normal situation and returned NULL value should be
        properly handled by the caller.

2010-07-02  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_getimage.c: Avoid wrong math du to the signed/unsigned
        integer type conversions. As per bug
        http://bugzilla.maptools.org/show_bug.cgi?id=2207

        * tools/{tiff2bw.c, thumbnail.c, pal2rgb.c}: Fix the count for

        http://bugzilla.maptools.org/show_bug.cgi?id=2216

        * libtiff/tif_dir.c: Set the bogus post-decoding hook when processing
        TIFFTAG_BITSPERSAMPLE in _TIFFVSetField() for the case of 8 bit when
        we don't need any post-processing. That helps to reset the hook if we
        previously set this field to some other value and the hook was
        initialized accordingly. As per bug
        http://bugzilla.maptools.org/show_bug.cgi?id=2035

2010-07-01  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiffgt.c: Properly check the raster buffer allocations for
        integer overflows. As per bug
        http://bugzilla.maptools.org/show_bug.cgi?id=2108

        * m4/acinclude.m4: Update GL/GLU/GLUt/Pthread macros from the
        upstream.

        * libtiff/{tif_aux.c, tif_strip.c, tif_tile.c, tiffiop.h}: Move
        multiply_32() and multiply_64() functions into tif_aux.c file and
        rename them into _TIFFMultiply32() and _TIFFMultiply64() respectively.

2010-06-30  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiff2pdf.c: Better generation of ID field in
        t2p_write_pdf_trailer(). Get rid of GCC aliasing warnings.

        * tools/tiff2pdf.c: Fixed computation of the tile buffer size when
        converting JPEG encoded tiles.

        * tools/tiff2pdf.c: Better handling of string fields, use static
        string buffers instead of dynamically allocated, use strncpy() instead
        of strcpy(), control the string lengths.

2010-06-25  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiffcp.c: Initialize buffer arrays with zero to avoid
        referencing to uninitialized memory in some cases (e.g. when tile size
        set bigger than the image size).

2010-06-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tools/tiffcrop.c: Patch from Richard Nolde. Reject YCbCr
        subsampled data since tiffcrop currently doesn't support it.  Fix
        JPEG support.

2010-06-13  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirinfo.c: Fix invocation of tag compare function (#2201)

        * tools/tiff2pdf.c: Fix assorted bugs in tiff2pdf: missing "return"
        in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
        wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
        size is larger.  Also, there are a bunch of places that try to
        memset() a malloc'd buffer before checking for malloc failure, which
        would result in core dump if there actually were a failure. (#2211)

2010-06-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tiffiop.h (TIFFSafeMultiply): Need more castings to
        avoid compiler warnings if parameter types are not sign
        consistent.

        * libtiff 4.0.0alpha6 released.

        * tools/tiffcrop.c: Applied patch from Richard Nolde: Corrected
        European page size dimensions.  Added an option to allow the user
        to specify a custom page size on the command line.  Fix the case
        where a page size specified with a fractional part was being
        coerced to an integer by retyping the variables that define the
        paper size.

        * html/index.html: Update for the 3.9.3 release.

        * tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject
        YCbCr subsampled data since tiffcp currently doesn't support it.
        http://bugzilla.maptools.org/show_bug.cgi?id=2097

        * Update libtool to version 2.2.10.

2010-06-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tiffiop.h (TIFFSafeMultiply): Work properly if
        multiplier is zero.

2010-06-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_fax3.c (Fax3SetupState): Yesterday's fix for
        CVE-2010-1411 was not complete.

        * libtiff/tiffiop.h (TIFFSafeMultiply): New macro to safely
        multiply two integers.  Returns zero if there is an integer
        overflow.

        * tools/tiffcp.c (main): tiffcp should not leak memory if an error
        is reported when reading the input file.

2010-06-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Update libtool to version 2.2.8.

        * libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of
        buffer due to integer overflow in TIFFroundup() and several other
        potential overflows.  In conjunction with the fix to TIFFhowmany(),
        fixes CVE-2010-1411.

        * libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
        result in an integer overflow. This causes TIFFroundup() to also
        return zero if there would be an integer overflow.

        * contrib: Add an emacs formatting mode footer to all source files
        so that emacs can be effectively used.

2010-06-03  Oliver Chen Feng <scip8183@gmail.com>

        * libtiff/tools/tiffcp.c: add a new option -x to force merged tiff
        file PAGENUMBER value in sequence for users who care the page
        sequence, this will also prevent tiff2pdf from creating pdf file from
        the merged tiff file with wrong page sequence.

2010-05-08  Olivier Paquet  <olivier.paquet@gmail.com>

        * libtiff/tif_dirread.c: Restored TIFFReadDirEntryFloat function in order
        to add missing TIFF_SETGET_FLOAT case to TIFFFetchNormalTag.
        * libtiff/tif_dirinfo.c: Use correct set_field_type for
        TIFFTAG_PIXAR_FOVCOT so it is readable again (regression from 3.9.2).

2010-05-07  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: Ensure that quality is always set in
        JPEGPreEncode(), not just when we want to output local tables.
        Otherwise the quality used during compression may not be right and
        might not match the tables in the tables tag.   This bug only occurs
        when seeking between directories in the midst of writing blocks.

        * libtiff/tif_print.c: Fixed printing of TIFFTAG_REFERENCEBLACKWHITE which
        had stopped working. Also made it always print 6 floats instead of
        2*SamplesPerPixel.
        http://bugzilla.maptools.org/show_bug.cgi?id=2191
        http://bugzilla.maptools.org/show_bug.cgi?id=2186
        * man/TIFFGetField.3tiff, man/TIFFSetField.3tiff: Fixed doc to reflect the
        fact that libtiff considers TIFFTAG_REFERENCEBLACKWHITE to be 6 floats.

2010-05-05  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: Fix to use memcmp(), not memcpy() when checking
        if the jpeg table was written.  This is a fix for the last fix on 04-21.

2010-04-21  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: avoid preparing jpeg tables every time
        JPEGSetupEncode() is called if the tables already seem to be
        established.  This prevents spurious updates and rewriting of
        directories with jpegtables when doing updates to existing images.
        http://trac.osgeo.org/gdal/ticket/3539

2010-04-20  Olivier Paquet  <olivier.paquet@gmail.com>

        * libtiff/tif_dirinfo.c: Use correct set_field_type for
        TIFFTAG_PIXAR_IMAGEFULLWIDTH, TIFFTAG_PIXAR_IMAGEFULLLENGTH,
        TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN and TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA.
        They were unreadable with TIFF_SETGET_UNDEFINED, a regression from 3.9.2.
        http://bugzilla.maptools.org/show_bug.cgi?id=2139

2010-04-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_dir.c (_TIFFVSetField): Add a special error case for
        when the tag count value is zero.  Error handling is still a
        regression since in 3.9.2, empty tags are skipped (with a warning)
        rather than returning a hard error and refusing to read the file.

        * tools/ppm2tiff.c (main): While case for parsing comment line
        requires extra parenthesis to work as expected.  Reported by
        Thomas Sinclair.

2010-04-02  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_read.c (primarily): Add support for
        CHUNKY_STRIP_READ_SUPPORT where large strips are
        read in chunks for applications using TIFFReadScanline().
        This is intended to make it more practical work with very
        large compressed one-strip files.   Feature is off by default.
        Enable by defining CHUNK_STRIP_READ_SUPPORT as a macro.
        http://trac.osgeo.org/gdal/ticket/3514

2010-03-31  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_flush.c: Use TIFFRewriteDirectory() when flushing
        directories so previously placed directories will be migrated to
        the end of file if needed.

2010-03-30  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_lzw.c: change type of dec_bitsleft field to uint64
        to support operating on strips/tiles of more than 256MB.
        http://trac.osgeo.org/gdal/ticket/3512

2010-03-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_aux.c (_TIFFCheckRealloc): Improve error message so
        that it is clearly a memory allocation error message, and also
        includes the size of the allocation request.

2010-02-22  Lee Howard  <faxguy@howardsilvan.com>

        * libtiff/tif_jpeg.c: Do not generate a JPEGTables tag when creating
        the JPEG TIFF as is is not required in order to prevent it from
        being unused and filled with invalid data.  (Leave it to be
        generated by later activity.)
        http://bugzilla.maptools.org/show_bug.cgi?id=2135
        * tools/tiff2pdf.c: Write the JPEG SOI headers into the TIFF strip
        data rather than skipping them.  This fixes the ability to view in
        Acrobat Reader, Evince, and Ghostscript.
        http://bugzilla.maptools.org/show_bug.cgi?id=2135
        * libtiff/tif_fax3.c: Don't return error on badly-terminated MMR
        strips.
        http://bugzilla.maptools.org/show_bug.cgi?id=2029

2009-12-03  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: Made JPEGDecodeRaw() check for buffer overruns.
        Made so that when working with downsampled images a stub function
        reporting an error is used for tif_decoderow.  We cannot meaningfully
        support reading scanlines in this situation.  (#1936)

        * libtiff/tif_jpeg.c: Ensure that tif_scanlinesize is computed after
        resetting of the upsampling values (gdal:#3259).
        http://bugzilla.maptools.org/show_bug.cgi?id=1936

2009-11-30  Frank Warmerdam  <warmerdam@pobox.com>

        * contrib/dbs/tiff-grayscale.c, contrib/tif-palette.c,
        tools/ras2tiff.c: Fix resource leaks on error.
        http://bugzilla.maptools.org/show_bug.cgi?id=2121

        * libtiff/tif_{aux.c,dir.c,dir.h,dirinfo.c}: Return to handling
        TIFFTAG_REFERENCEBLACKWHITE as a field in the TIFF directory instead
        of as a custom(generic) field to avoid a potential reentrancy problem.
        http://bugzilla.maptools.org/show_bug.cgi?id=2125

        * libtiff/tif_color.c, libtiff/tif_getimage.c, libtiff/tiffio.h,
        man/TIFFcolor.3tiff: Make TIFFDisplay argument in TIFFCIELabToRGBInit
        const, and display_sRGB static and const.
        http://bugzilla.maptools.org/show_bug.cgi?id=2124

2009-11-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff 4.0.0alpha5 released.

2009-11-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tools/tiffcrop.c: Updated tiffcrop from Richard Nolde.  This
        version has undergone substantial testing with arbitrary sample
        bit depths.  Also eliminates GCC compilation warnings.

2009-11-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * port/libport.h: Add extern declarations for getopt standard
        globals.

2009-10-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        noticed in 64-bit build of libtiff with Visual Studio 2005.
        Resolves "Bug 2067 - Visual Studio 2005 64-bit warnings in
        tif_lzw.c", http://bugzilla.maptools.org/show_bug.cgi?id=2067

        * libtiff/tif_pixarlog.c (PixarLogEncode): Fix non-important
        warning noticed in Visual Studio 2005 build. Resolves "Bug 2068 -
        Visual Studio 2005 64-bit warning in tif_pixarlog.c",
        http://bugzilla.maptools.org/show_bug.cgi?id=2068

2009-10-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        description of tiffcrop.

2009-10-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: x86_64 should use the same fill order as i386.

2009-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tools/tiffcrop.c, man/tiffcrop.1: New tiffcrop from Richard
        Nolde.  Major updates to add significant functionality for reading
        and writing tile based images with bit depths not a multiple of 8
        which cannot be handled by tiffcp.

2009-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_ojpeg.c (OJPEGWriteHeaderInfo): IJG JPEG 7 needs
        do_fancy_upsampling=FALSE in order to read raw data.  Resolves
        "Bug 2090 - OJPEG crash with libjpeg v7".
        http://bugzilla.maptools.org/show_bug.cgi?id=2090

2009-09-03  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_getimage.c: Fixed error recognition handling in RGBA
        interface when stoponerror is set.

        * test/{bmp2tiff_palette.sh, bmp2tiff_rgb.sh, gif2tiff.sh,
        ppm2tiff_pbm.sh, ppm2tiff_pgm.sh, ppm2tiff_ppm.sh}: Additional
        utilities tests.

2009-08-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tools/tiffinfo.c: tiffinfo should return error status to the
        caller.  Register a private error callback to accomplish that.

        * test/Makefile.am (TIFFIMAGES): Add test images in BMP, GIF, and
        PNM formats so that we will be able to test more of the tools.
        While adding these test images I notice that bmp2tiff and gif2tiff
        only support ancient versions of their respective formats.

2009-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff 4.0.0alpha4 released.

        * HOWTO-RELEASE: Improved release instructions.

        fixes for "Bug 2023 - nroff errors in manual pages".
        http://bugzilla.maptools.org/show_bug.cgi?id=2023

        * tools/{rgb2ycbcr.c, tiff2rgba.c}: Applied fixes for "Bug 2079 -
        CVE-2009-2347 libtiff: integer overflows in various inter-color
        space conversion tools".
        http://bugzilla.maptools.org/show_bug.cgi?id=2079

        * test/Makefile.am, test/tiffcrop*.sh: Split previously existing
        tiffcrop.sh into a collection of many specific tests.  Re-wrote
        all of the existing tests to be based on some simple shell
        functions.  Make distcheck works again.

        Export certain variables (MAKE, MAKEFLAGS, MEMCHECK) to tests and
        added 'memcheck' and 'ptrcheck' targets to make it easy to run the
        tests under valgrind.

        * test/tiffcp-logluv.sh: Fix test so that it works with a VPATH
        build.

        * test/Makefile.am (AUTOMAKE_OPTIONS): Colorized tests was not
        actually activated since it needed to be enabled in this
        Makefile.am.  Also activated parallel-tests mode since it offers
        useful features such as per-test .log files and a summary test
        report .log file.

2009-08-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Updated autotools.  Autoconf 2.64, Automake 1.11,
        libtool 2.2.6.  Enabled support for silent build rules
        (--enable-silent-rules or 'make V=0') and colorized tests.

        * html/{index.html, v3.9.0.html}: Update for 3.9.0 release.

2008-09-05  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiffsplit.c: Use byte counts of proper size (uint64).
        Required for libtiff 4.0.

        * tools/tiffsplit.c: Use dynamically allocated array instead of static
        when constructing output file names.

2008-09-03  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiffsplit.c: Get rid of unsafe strcpy()/strcat() calls when
        doing the filename/path construction.

        * tools/tiff2pdf.c: More appropriate format string in
        t2p_write_pdf_string(); avoid signed/unsigned mismatch.

        * libtiff/tif_lzw.c: Properly zero out the codetable. As per bug

        http://bugzilla.maptools.org/show_bug.cgi?id=1929

        * libtiff/tif_lzw.c: Properly zero out the string table. Fixes
        CVE-2008-2327 security issue.

2008-09-01  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirread.c: Avoid unused TIFFReadDirEntryFloat() function.

        * libtiff/tif_dirwrite.c: modified to write IFDs as either IFD8 or IFD
        depending on whether the file is bigtiff or classic tiff.
        http://bugzilla.maptools.org/show_bug.cgi?id=1917

2008-08-12  Edward Lam  <edward@sidefx.com>

        * tools/tiffdump.c: When compiling for Microsoft Windows, apply
        consistent (__int64) casting when testing if _lseeki64 has
        successfully sought as requested.  This is necessary for large
        file support to work since off_t is only 32-bit.

2008-07-29  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_strip.c: Replace assertions related to samplesperpixel != 3 or
        the subsampling values not being 1, 2 or 4 (for jpeg compressed images)
        with control logic to return runtime errors (c/o Even Rouault) (#1927).

2008-06-17  Frank Warmerdam  <warmerdam@pobox.com>

        * tools/tiffcrop.c: Fix some portability problems.

        * libtiff/tif_ojpeg.c: Use same jpeg/win32 boolean/FAR hacks as are
        used in tif_jpeg.c.

        * libtiff/tif_win32.c: Ensure TIFFOpenW() uses same FILE_SHARE flags
        as TIFFOpen().

2008-06-01  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirwrite.c: Fix alignment problems affecting architectures

2008-05-26  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_config.*.h, tiffconf.*.h: Remove SIZEOF_LONG definition, unused.

        * li2008-04-15  Andrey Kiselev  <dron@ak4719.spb.edu>

btiff/tif_win32.c: Replace custom Win32 memory api with generic
        POSIX one.  No apparent value to use of GlobalAlloc() in the modern
        age.  http://bugzilla.maptools.org/show_bug.cgi?id=1885

        * libtiff/tiffconf.vc.h: Added JBIG_SUPPORT and MDI_SUPPORT items
        in windows version (care of Edward Lam).

2008-05-24  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_codec.c: Avoid NULL pointer dereferencing for exotic
        compression codec codes.

        * tif_dirwrite.c: fix potential memory leak.

        * tif_dirread.c: Fix unchecked malloc result.

2008-05-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        tiffcp-split-join.sh tiffcp-split.sh tiffcp-thumbnail.sh
        tiffdump.sh tiffinfo.sh}: Added more test scripts based on
        suggestions from Lee Howard posted to the tiff list on 13 Sep
        2007.

2008-05-23  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_fax3.c: Add an assert in an effort to detect a
        possible runtime problem reported by coverity.

        * contrib/iptcutil/iptcutil.c: Fixed memory leak of str.

        * tools/tiffcrop.c, man/tiffcrop.1: Major update from Richard Nolde.
        http://bugzilla.maptools.org/show_bug.cgi?id=1888

        * tools/tiffdither.c: remove dead onestrip code.  avoid memory leak.

        * tools/rgb2ycbcr.c: fix memory leak of raster buffer.

        Cleanup scanline allocation to avoid coverity warning.

        * tools/thumbnail.c: Check for TIFFOpen() failure.

2008-05-18  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirinfo.c: Use TIFF_SETGET_ASCII for PIXAR_TEXTUREFORMAT
        and PIXAR_WRAPMODES instead of TIFF_SETGET_UNDEFINED.  Not exactly clear
        why this is needed.

2008-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * Makefile.am (ACLOCAL_AMFLAGS): Libtool 2.2.4 does not like
        "ACLOCAL_AMFLAGS=-I ./m4".  It wants "ACLOCAL_AMFLAGS=-I m4".

2008-04-15  Andrey Kiselev  <dron@ak4719.spb.edu>

        * test/: Test suite updated. Everything is passed now.

        * libtiff/tif_dirinfo.c: Fixed description of the
        TIFFTAG_NUMBEROFINKS tag.

2008-04-14  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/{tif_dirread.c, tif_dirwrite.c, tiffiop.h}:
        Get rid of some of "dereferencing type-punned" warnings by converting
        tdir_offset field of TIFFDirEntry structure into union.

2008-04-10  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/{tif_flush.c, tif_dirwrite.c, tiffio.h, tiffiop.h}:
        TIFFRewriteField() renamed into _TIFFRewriteField() and moved out
        from the public interface. Type of its 'count' parameter changed
        from uint32 to tmsize_t.

        * /libtiff/tiffiop.h: Make tif_nfields and tif_nfieldscompat fields
        of the tiff structure have the size_t type instead of uint32.

2008-04-09  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiffdump.c: Added support for MSVS 6.0.

        * libtiff/tif_dirread.c: Use custom functions _TIFFUInt64ToFloat()
        and _TIFFUInt64ToDouble() to convert 64-bit integers into floating
        point values on MSVS 6.0 platform.

2008-03-14  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dirread.c: Removed sanity checks on tags larger than 4MB in
        TIFFReadDirEntryArray() since they are interfering with seemingly
        legitimate files.  http://trac.osgeo.org/gdal/ticket/2005

2008-02-09  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_dirread.c: Added handling for the case of number of values for
        PageNumber tag different from 2 (previously resulted in an assert
        indicating lack of handling and was forgotten about)

2008-02-01  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: Do not try to fixup subsampling tags based on
        the actual jpeg data stream if the first strip/tile has zero size.
        This is the case when GDAL creates a new file with zero sizes, closes
        and reopens it.

2008-01-07  Frank Warmerdam  <warmerdam@pobox.com>

        * tools/tiff2ps.c: fix up 64bit issues (from Edward Lam).

2008-01-01  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_dirwrite.c: #ifdef out lots of unused functions.

        * Makefile.vc, libtiff/Makefile.vc, tools/Makefile.vc: Improve clean
        targets.

        * tools/tiffinfo.c, tools/tiffcmp.c, tools/gif2tiff.c, tools/bmp2tiff.c
        tools/tiff2pdf.c: Fix 64-bit warnings when compiling under MSVC 2005
        (x64).

        * tools/tiffset.c: Changes to reflect the fact that TIFFFieldWithTag()
        and TIFFFieldWithName() now return TIFFField pointers instead of
        TIFFFieldInfo pointers.

        * tools/tiffdump.c: Added ssize_t typedef on Windows since it doesn't
        exist. This makes it compile again on Windows

        * tif_aux.c, tif_getimage.c, tif_next.c, tif_predict.c, tif_win32.c,
        tiffconf.vc.h: Various 64bit fixes from Edward Lam identified on win64.

        * test/rewrite_tag.c: New test for TIFFRewriteField().

2007-12-31  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dirwrite.c: Added TIFFRewriteField().  This new function
        rewrites one field "on disk" updating an existing directory
        entry.  Lots of limitations still...

        * tiffiop.h, tif_write.c, tif_dirread.c, tif_flush.c: Keep track of
        TIFF_DIRTYSTRIP separately from TIFF_DIRTYDIRECT to indicate that
        the strip offset/size values are dirty but nothing else about the
        directory is dirty.  In flush handle "just stripmaps dirty" as a
        special case that just rewrites these values without otherwise
        modifying the directory on disk using TIFFRewriteField().

        We also modify logic so that in update mode the directory is not
        marked dirty on read, but only when something is changed.  This
        means we need to keep track of updates to the stripmap stuff in
        TIFFAppendToStrip().

2007-12-10  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_jpeg.c: Improve ability to switch between encoding and decoding
        in the jpeg code (gdal bug #2033).

2007-11-23  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dir.c, tif_dirread.c, tif_dirwrite.c, tif_read.c, tif_write.c,
        tiffiop.h: Added TIFF_BUF4WRITE flag to indicate if contents of the
        rawcp/rawcc buffer are for writing and thus may require flushing.
        Necessary to distinguish whether they need to be written to disk when
        in mixed read/write mode and doing a mixture of writing followed by
        reading.  http://trac.osgeo.org/gdal/ticket/1758

2007-11-23  Andrey Kiselev  <dron@ak4719.spb.edu>

        * configure.com, libtiff/tif_vms.c: Better OpenVMS support. Patches
        from Alexey Chupahin.

2007-11-02  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for
        establishing if an existing tile can be rewritten to the same location
        by comparing the current size to all the other blocks in the same
        directory.  This is dangerous in many situations and can easily
        corrupt a file.  (observed in esoteric GDAL situation that's hard to
        document).  This change involves leaving the stripbytecount[] values
        unaltered till TIFFAppendToStrip().  Now we only write a block back
        to the same location it used to be at if the new data is the same
        size or smaller - otherwise we move it to the end of file.

        * tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
        data when writing the directory just because we have BEENWRITING at
        some point in the past.  This was causing odd junk to be written out
        in a tile of data when a single tile had an interleaving of reading
        and writing with reading last.  (highlighted by gdal
        autotest/gcore/tif_write.py test 7.

        * tif_predict.c: use working buffer in PredictorEncodeTile to avoid
        modifying callers buffer.
        http://trac.osgeo.org/gdal/ticket/1965

        * tif_predict.c/h: more fixes related to last item, keeping a
        distinct pfunc for encode and decode cases as these were getting
        mixed up sometimes.
        http://trac.osgeo.org/gdal/ticket/1948

2007-11-01  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_predict.c/h, tif_lzw.c, tif_zip.c: Improvements so that
        predictor based encoding and decoding works in read-write update
        mode properly.
        http://trac.osgeo.org/gdal/ticket/1948

2007-10-24  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_dirread.c: Fixed problem with bogus file triggering
        assert(td->td_planarconfig == PLANARCONFIG_CONTIG) in
        ChopUpSingleUncompressedStrip

2007-10-22  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_jpeg.c: Resolved buffer incrementation bug that lead to faulty images
        at best, access violation at worst, when subsampled JPEG compressed imagery
        is decoded without the JPEG_COLORMODE feature

2007-10-11  Frank Warmerdam  <warmerdam@pobox.com>

        * html/index.html: Update "people responsible" section.

2007-10-05  Frank Warmerdam  <warmerdam@pobox.com>

        * tools/tiff2pdf.c: Fix problem with alpha setting in some cases
        as reported on the mailing list.

2007-10-01  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * changed some more incorrect %lud printf flags to %lu

2007-09-29  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_dirread.c: Strip chopping interfered badly with uncompressed
        subsampled images because it tried to divide subsampled rowblocks,
        leading to all sorts of errors throughout the library for these
        images. Fixed by making strip chopping divide in row counts that
        are a multiple of vertical subsampling value.

2007-09-28  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_dirread.c: Logical cast working around compiler warning

        * tif_read.c: Correction of some error flags and parameter lists

2007-09-27  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_dirread.c: Made calculation of td_maxsamplevalue more robust
        when dealing with large bitspersample values, shutting up purification
        tools that warn about truncation, though it remains incorrect and
        indicates a conceptual problem there.

        * tif_open.c: Moved early exit in case of 'h' flag (to disable reading
        of first IFD) to proper place because it badly interfered with memory
        mapping, resulting in mapping flag even with dummy mapping functions
        that returned 0 whilst at the same time the mapping tif_size wasn't
        set, thus resulting in continuous incorrect beyond-eof errors.

2007-09-24  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * tif_dirinfo.c: Fixed (MSVC) compiler reports about
        inconsistent use of const in tiffFields and exifFields definition

2007-09-20  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dirwrite.c: Always write tile/strip offsets and sizes
        using LONG8 type when output format is BigTIFF.  The
        TIFFWriteDirectoryTagLongLong8Array() function was restructured
        accordingly.

        * tif_dirread.c: Improvements to error reporting text in
        TIFFFetchDirectory().

2007-09-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * test/images: Added a small collection of test images for use by
        test programs and scripts.
        * test/tiffinfo.sh: A trivial example test script.
        * test/common.sh: Added small script for setting the environment
        used by script-based tests.

2007-08-24  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dirwrite.c: Write the tif_nextdiroff value instead of a fixed
        zero when writing directory contents to preserve the ability to
        rewrite directories in place, even in the middle of a directory
        chain.

        * tif_dirinfo.c:  _TIFFMergeFields() now only merges in field
        definitions that are missing.  Existing definitions are silently
        ignored.

        * tif_dirread.c: Add runtime error for fields for which no definition
        is found (in addition to an assert for developers) in
        TIFFFetchNormalTag().  Not sure if this is needed, but it seems
        prudent.

2007-08-10  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * libtiff/tif_getimage.c: removed SubsamplingHor and SubsamplingVer
        from _TIFFRGBAImage structure to revert unwanted ABI change.

2007-08-10  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * libtiff/tif_win32.c: use SetFilePointer instead of
        SetFilePointerEx, as per bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=1580

2007-07-19  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_stream.cxx: Put all callback functions declarations
        inside extern "C" block.

        * libtiff/{tif_lzw.c, tif_luv.c, tif_dumpmode.c, tif_print.c,
        tif_read.c, tif_strip.c, tif_thunder.c}: Use "%I64d" printf()
        formatter instead of "%lld" with MSVC compiler.

        * libtiff/{tiffiop.h, tif_aux.c}:  Added _TIFFUInt64ToFloat() and
        _TIFFUInt64ToDouble() functions.

2007-07-18  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_dirread.c: Handle the case of MSVC 6 when using 64-bit
        integer constants.

        * libtiff/{Makefile.am, Makefile.v}: Do not distribute tiffconf.h,
        remove tif_config.h/tiffconf.h during cleaning. As per bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=1573

        * libtiff/tif_unix.c: Do not use O_LARGEFILE. As per bug

        * libtiff 4.0.0alpha released.

2007-07-12  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiff2pdf.c: Added missed extern optind as per bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=1567

        * libtiff/{tif_close.c, tif_dirinfo.c, tiffiop.c, tif_dirread.c,
        tif_dir.h, tif_dir.c, tiffio.h}: Transition to the new-style tag
        extending scheme completed.

2007-07-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * libtiff/tif_stream.cxx: Adapt to use toff_t again.  Update to
        use standard C++ library size types and attempt to detect overflow
        cases.

2007-07-08  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/{tif_jpeg.c, tif_dir.h, tif_dir.c, tif_dirinfo.c, tiffio.h,
        tif_ojpeg.c, tif_print.c, tif_fax3.c, tif_dirread.c}: More work on new
        tag extending scheme. Use the new scheme everywhere.

        * libtiff/{tif_zip.c, tif_predict.c, tif_pixarlog.c, tif_luv.c,
        tif_fax3.c, tif_dirread.c, tif_dirwrite.c, tif_close.c, tif_ojpeg.c,
        tif_jpeg.c, tif_dirinfo.c, tif_dir.h, tiffio.h, tiffiop.h}:
        TIFFFIeldInfo structure replaced with TIFFField structure.
        TIFFFieldInfo retained for the backward compatibility.

2007-07-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tools/tiff2pdf.c: Fix a compile problem when JPEG_SUPPORT is not
        defined.

2007-07-04  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/{tif_dir.c, tiff.h, tiffio.h, libtiff.def}: Unused
        TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration
        removed.

        * libtiff/{tif_dirinfo.c, tif_fax3.c, tif_jbig.c, tif_jpeg.c}: Move
        tags TIFFTAG_FAXRECVPARAMS, TIFFTAG_FAXSUBADDRESS,
        TIFFTAG_FAXRECVTIME and TIFFTAG_FAXDCS to the common tag directory.
        These tags are not codec-specific and relate to image content, so
        process them as other normal tags.

        * libtiff/{tiffio.h, tif_dir.h}: TIFFTagValue structure moved from the
        public tiffio.h to private tif_dir.h.

        * contrib/{acorn, mac-cw, mac-mpw}: Removed as unmaintained and
        outdated.

2007-07-03  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff{tif_acorn.c, tif_apple.c, tif_atari.c, tif_msdos.c,
        tif_win3.c}: Obsoleted portability stuff removed.

        * tools/tiff2ps.c:  Added support 16-bit images as per bug

        Patch from William Bader.

        * tools/tiff2pdf.c: Fix for TIFFTAG_JPEGTABLES tag fetching and
        significant upgrade of the whole utility as per bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=1560

        Now we don't need tiffiop.h in tiff2pdf anymore and will open output
        PDF file using TIFFClientOpen() machinery as it is implemented
        by Leon Bottou.

2007-06-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Fix typo when substituting value for unsigned 8 bit type.
        Added support for a TIFF_PTRDIFF_T type to use when doing pointer arithmetic.
        Added support for a TIFF_SSIZE_T in order to return memory sizes but still
        allow returning -1 for errors.
        * libtiff/tiffconf.vc.h: Add porting type defintions for WIN32.

2007-06-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * port/strtoull.c: New porting function in case strtoull() is not
        available on the target system.
        * configure.ac: Add configure support for determining sized types
        in a portable way and performing necessary substitutions in
        tif_config.h and tiffconf.h.  Updated tiff.h to use the new
        definitions.

2007-04-27  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiff2pdf.c: Check the tmpfile() return status as per bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=154

2007-04-07  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/{tif_dir.h, tif_dirread.c, tif_dirinfo.c, tif_jpeg.c,
        tif_fax3.c, tif_jbig.c, tif_luv.c, tif_ojpeg.c, tif_pixarlog.c,
        tif_predict.c, tif_zip.c}: Finally fix bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=1274

        by introducing _TIFFMergeFieldInfo() returning integer error status
        instead of void in case of problems with field merging (e.g., if the
        field with such a tag already registered). TIFFMergeFieldInfo() in
        public API remains void. Use _TIFFMergeFieldInfo() everywhere and
        check returned value.

2007-04-07  Frank Warmerdam  <warmerdam@pobox.com>

        * contrib/addtiffo/tif_overview.c: Fix problems with odd sized output
        blocks in TIFF_DownSample_Subsampled() (bug 1542).

2007-04-06  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
        will convert from decompressor to compressor or compress to decompress
        if required by the force arguments.  This works around a problem in
        where the JPEGFixupTestSubsampling() may cause a decompressor to
        be setup on a directory when later a compressor is required with the
        force flag set.  Occurs with the addtiffo program for instance.

2007-04-06  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiffcrop.c, man/tiffcrop.1: Significant update in

2007-03-07  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * libtiff/tif_getimage.c: workaround for 'Fractional scanline' error reading
        OJPEG images with rowsperstrip that is not a multiple of vertical subsampling
        factor. This bug is mentioned in:
        http://bugzilla.remotesensing.org/show_bug.cgi?id=1390
        http://www.asmail.be/msg0054766825.html

2007-02-27  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_dirread.c: Use uint32 type instead of tsize_t in byte
        counters in TIFFFetchData(). Should finally fix the issue

        http://bugzilla.remotesensing.org/show_bug.cgi?id=890

2007-02-24  Andrey Kiselev  <dron@ak4719.spb.edu>

        * tools/tiff2pdf.c: Do not assume inches when the resolution units
        do not specified. As per bug

        http://bugzilla.remotesensing.org/show_bug.cgi?id=1366

        * tools/{tiffcp.c, tiffcrop.c}: Do not change RowsPerStrip value if

        Though it is still far from the state of being working and useful.

2006-10-12  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_fax3.c: Save the state of printdir codec dependent
        method.

        * libtiff/tif_lzw.c, libtiff/tif_zip.c: Fixed problems with mixing
        encoding and decoding on the same read-write TIFF handle.  The LZW
        code can now maintain encode and decode state at the same time. The
        ZIP code will switch back and forth as needed.
        http://bugzilla.remotesensing.org/show_bug.cgi?id=757

2006-09-20  Frank Warmerdam  <warmerdam@pobox.com>

        data in _TIFFWriteDirectory if TIFF_BEENWRITING not set.  Relates
        to bug report by Peng Gao with black strip at bottom of images.

2006-07-12  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dirwrite.c: make sure to use uint32 for wordcount in
        TIFFWriteNormanTag if writecount is VARIABLE2 for ASCII fields.
        It already seems to have been done for other field types.  Needed
        for "tiffset" on files with geotiff ascii text.

2006-07-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * {configure.ac, libtiff/tif_config.h.vc, libtiff/tif_jbig.c}
        (JBIGDecode): jbg_newlen is not available in older JBIG-KIT and
        its use does not appear to be required, so use it only when it is
        available.

2006-06-17  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_readdir.c: Added case in EstimateStripByteCounts() for tiled
        files.  Modified TIFFReadDirectory() to not invoke
        EstimateStripByteCounts() for case where entry 0 and 1 are unequal
        but one of them is zero.
          http://bugzilla.remotesensing.org/show_bug.cgi?id=1204

2006-06-08  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/tif_getimage.c: Revision of all RGB(A) put routines
        - Conversion of unassociated alpha to associated alpha now done with
          more performant LUT, and calculation more correct
        - Conversion of 16bit data to 8bit data now done with
          more performant LUT, and calculation more correct
        - Bugfix of handling of 16bit RGB with unassociated alpha

2006-04-11  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * libtiff/tif_getimage.c:
        - When there is no alpha, gtTileSeparate and gtStripSeparate allocated
          buffer for alpha strile and filled it, only to never read it back.
          Removed allocation and fill.
        - Minor rename of vars in gtTileSeparate and gtStripSeparate
          anticipating planned functionality extension

        and pickTileSeparateCase to PickSeparateCase as both work on strips as
        well

        * libtiff/tif_getimage.c: moved img->get selection from
        TIFFRGBAImageBegin into PickContigCase and PickSeparateCase to create
        logical hook for planned functionality extension

2006-04-08  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        of inappropriate use of jpeg_abort instead of jpeg_destroy

2006-04-07  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * libtiff/tif_getimage.c: replaced usage of TIFFScanlineSize in
        gtStripContig with TIFFNewScanlineSize so as to fix buggy behaviour
        on subsampled images - this ought to get sorted when we feel brave
        enough to replace TIFFScanlineSize altogether

        * libtiff/tif_ojpeg.c: fixed bug in OJPEGReadSkip

2006-04-04  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        of OJPEG images in favor of tif_getimage.c native handling of
        YCbCr and desubsampling

2006-03-29  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: JPEGVSetField() so that altering the photometric
        interpretation causes the "upsampled" flag to be recomputed.  Fixes
        peculiar bug where photometric flag had to be set before jpegcolormode
        flag.

2006-03-25  Joris Van Damme  <joris.at.lebbeke@skynet.be>

        * libtiff/tif_jpeg.c: strip size related bugfix in encode raw

        * libtiff/tif_strip.c: temporarilly added two new versions of
        TIFFScanlineSize
          - TIFFNewScanlineSize: proposed new version, after all related
            issues and side-effects are sorted out
          - TIFFOldScanlineSize: old version, from prior to 2006-03-21 change
        This needs further sorting out.

        this causes failure to build on systems which properly respect
        this request.

        * libtiff/tiffconf.h.in: New file to act as the template for the
        configured tiffconf.h

        * libtiff/tif_lzw.c: Move LZW codec state block allocation back to
        TIFFInitLZW(), because its initialization in LZWSetupDecode() cause
        problems with predictor initialization. Remove O_RDONLY check during
        state block allocation to be able open LZW compressed files in update
        mode.

        Problem exist for libtiff version of the tif_lzw.c module. One from
        lzw-compression-kit hasn't such troubles.

2003-08-04  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_write.c: modified tif_write.c so that the various
        encoded write functions use tif_postdecode() to apply byte order
        swapping (swab) to the application passed data buffer if the same
        would be done when reading.  This allows us to write pixel data with
        more than 8 bits per sample to existing files of a non-native byte
        order.  One side effect of this change is the applications buffer
        itself is altered in this case by the act of writing.

        the scanline buffer long enough when writing rgb triplets.
        The scanline needs to be 3 X the number of dots or else it will

        the eps by redefining the colorimage operator will get messed up.
        Patch supplied by William Bader.

        additional members tif->tif_decodestatus and tif->tif_encodestatus
        for correct handling of unconfigured codecs (we should not try to read
        data or to define data size without correct codecs).

        * libtiff/tif_getimage.c: The way of codecs checking in TIFFRGBAImageOK
        changed. Now it has used tif->tif_decodestatus and
        tif->tif_encodestatus.

        files by skipping bad strips.
        Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=100

2002-04-03  Frank Warmerdam  <warmerdam@pobox.com>

        http://bugzilla.remotesensing.org/show_bug.cgi?id=111

        * tif_print.c: Fixed so that ASCII FIELD_CUSTOM values with
        passcount set FALSE can be printed (such as TIFFTAG_SOFTWARE).

        * libtiff/tif_dir.c,tif_dirinfo.c,tif_dir.h,tif_ojpeg.c: modified so
        that TIFFTAG_SOFTWARE uses FIELD_CUSTOM as an example.

2002-03-26  Dwight Kelly  <dbmalloc@remotesensing.org>

        * libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
        tif_dirwrite.c: Added get/put code for new tag XMLPACKET as defined
        in Adobe XMP Technote. Added missing INKSET tag value from TIFF 6.0 spec
        INKSET_MULTIINK (=2). Added missing tags from Adobe TIFF technotes:
        CLIPPATH, XCLIPPATHUNITS, YCLIPPATHUNITS, OPIIMAGEID, OPIPROXY and
        INDEXED. Added PHOTOMETRIC tag value from TIFF technote 4 ICCLAB (=9).

2002-03-26  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/: tif_getimage.c: TIFFReadRGBAStrip and TIFFReadRGBATile

        Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=110

2002-03-15  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c,
        tif_dirwrite.c: Added routine TIFFDataWidth for detrmining
        TIFFDataType sizes instead of working with tiffDataWidth array
        directly. Should prevent out-of-borders bugs in case of unknown or
        broken data types.  EstimateStripByteCounts routine modified, so it
        won't work when tags with uknown sizes founded.
        Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=109

2002-03-13  Andrey Kiselev  <dron@ak4719.spb.edu>

        http://bugzilla.remotesensing.org/show_bug.cgi?id=99

2002-03-08  Andrey Kiselev  <dron@ak4719.spb.edu>

        * libtiff/Makefile.in, tools/Makefile.in: Shared library will not

        http://bugzilla.remotesensing.org/show_bug.cgi?id=97

        * configure: Modify CheckForBigEndian so it can work in a cross
        compiled situation.

        * tools/tiffset.c: fix bug in error reporting.

        * tools/tiffcp.c: fix several warnings that show up with -Wall.

2002-01-04  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_jpeg.c: fixed computation of segment_width for
        tiles files to avoid error about it not matching the
        cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile
        size.") for ITIFF files.  Apparently the problem was incorporated since
        3.5.5, presumably during the OJPEG/JPEG work recently.

2001-12-15  Frank Warmerdam  <warmerdam@pobox.com>

        * configure, libtiff/Makefile.in: Changes for building on MacOS 10.1.

        http://bugzilla.remotesensing.org/show_bug.cgi?id=94

        * libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
        (defined in tiffconf.h - 1 by default) then the RGBA interface
        will assume that a fourth extra sample is ASSOCALPHA if the
        EXTRASAMPLE value isn't set for it.  This changes the behaviour of
        the library, but makes it work better with RGBA files produced by
        lots of applications that don't mark the alpha values properly.

        http://bugzilla.remotesensing.org/show_bug.cgi?id=93
        http://bugzilla.remotesensing.org/show_bug.cgi?id=65

        * Makefile.in: Ensure that tiffvers.h is regenerated in the
        make release target.

        * Makefile.in: added libtiff/tiffvers.h to the release file list.

        error about LZW not being available.

        * libtiff/tif_dir.c: propagate failure to initialize compression
        back from TIFFSetField() as an error status, so applications can
        detect failure.

        * libtiff/tif_dir.c: removed the auto replacement of
        COMPRESSION_LZW with COMPRESSION_NONE in _TIFFVSetField().

        * Removed Makefile, tools/Makefile, port/install.sh, man/Makefile
        from CVS as they are all supposed to be auto-generated by configure.

        cost in performance.

        http://bugzilla.remotesensing.org/show_bug.cgi?id=54

        * libtiff/Makefile.in: Fixed @DSOSUB_VERSION to be @DSOSUF_VERSION@
        in two places.

        * libtiff/tif_getimage.c: Fixed problem with reading strips or
        tiles that don't start on a tile boundary.  Fix contributed by

        buffers.  See Bug 69 in Bugzilla.

        http://bugzilla.remotesensing.org/show_bug.cgi?id=69

        * tools/tiff2rgba.c: fixed getopt() call so that -b works again.

         - Try to handle /usr/bin/sh instead of /bin/sh where necessary.
         - Upgrade to HP/UX 10.x+ compiler, linker and dso options.
         - Fixed mmap() test to avoid MMAP_FIXED ... it isn't available on HP
         - Use -${MAKEFLAGS} in sub makes from makefiles.

2001-04-02  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tiff.h: Applied hac to try and resolve the problem
        with the inttypes.h include file on AIX.

        See http://bugzilla.remotesensing.org/show_bug.cgi?id=39

        * VERSION: update to 3.5.7 beta in preparation for release.

        * configure/config.site: modified to check if -lm is needed for
        MACHDEPLIBS if not supplied by config.site.  Needed for Darwin.

        * config.guess: updated wholesale to an FSF version apparently
        from 1998 (as opposed to 1994).  This is mainly inspired by
        providing for MacOS X support.

2001-03-29  Frank Warmerdam  <warmerdam@pobox.com>

        * configure, Makefile.in, etc: added support for OPTIMIZER being
        set from config.site.

2001-03-28  Frank Warmerdam  <warmerdam@pobox.com>

        * fax2ps.c: Helge (libtiff at oldach.net) submitted fix:

        Here's a fix for fax2ps that corrects behaviour for non-Letter paper
        sizes. It fixes two problems:

        Without scaling (-S) the fax is now centered on the page size specified
        with -H and/or -W. Before, fax2ps was using an obscure and practically
        useless algorithm to allocate the image relative to Letter sized paper
        which sometime sled to useless whitespace on the paper, while at the
        same time cutting of the faxes printable area at the opposite border.

        Second, scaling now preserves aspect ratio, which makes unusual faxes
        (in particular short ones) print properly.

        See http://bugzilla.remotesensing.org/show_bug.cgi?id=35

        * tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
        Bruce A. Mallett.  See check message for detailed information
        on all the changes, including a faster encoder, fixes for level
        2 PostScript, and support for the imagemask operator.

2001-03-27  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tiffio.h: Changed "#if LOGLUV_PUBLIC" to
        "#ifdef LOGLUV_PUBLIC" so it will work with VisualAge on AIX.

        http://bugzilla.remotesensing.org/show_bug.cgi?id=39

2001-03-16  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_dirinfo.c: moved definition of copyright tag in field list.
        Apparently they have to be in sorted order by tag id.

2001-03-13  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_getimage.c: Added support for 16bit minisblack/miniswhite
        images in RGBA interface.

2001-03-02  Frank Warmerdam  <warmerdam@pobox.com>

        * Added TIFFTAG_COPYRIGHT support.

2001-02-19  Frank Warmerdam  <warmerdam@pobox.com>

        * Brent Roman contributed updated tiffcp utility (and tiffcp.1)
        with support for extracting subimages with the ,n syntax, and also
        adding the -b bias removal flag.

2001-02-16  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/libtiff.def: Brent Roman submitted new version adding
        serveral missing entry points.

        * libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
        Some sort of weird VMS thing.

        http://bugzilla.remotesensing.org/show_bug.cgi?id=31

        * tif_luv.c/tiff.h/tiffio.h:
        New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
        (greg@shutterfly.com).  He writes:

        1) I improved the gamut-mapping function in tif_luv.c for imaginary
        colors, because some images were being super-saturated on the input
        side and this resulted in some strange color shifts in the output.

        2) I added a psuedotag in tiff.h to control random dithering during
        LogLuv encoding.  This is turned off by default for 32-bit LogLuv and
        on for 24-bit LogLuv output.  Dithering improves the average color
        accuracy over the image.

        3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
        tiffio.h, to expose internal routines for converting between LogLuv and
        XYZ coordinates.  This is helpful for writing more efficient,
        specialized conversion routines, especially for reading LogLuv files.

        Changes applied with minor edits.

2001-01-23  Frank Warmerdam  <warmerdam@pobox.com>

        * tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
        whether we are encoding or decoding.  This is to ensure graceful
        recovery if TIFFClientOpen() discovers an attempt to open a compressed
        file for "r+" access, and subsequently close it, as it resets the
        tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
        compressor's concept of whether it is in encode or decode mode.

2001-01-08  Mike Welles <mike@bangstate.com>

        * Makefile.in:  Now cleaning up after itself after creating the .tar.gz and .zip

2001-01-07  Frank Warmerdam  <warmerdam@pobox.com>

        * html/libtiff.html: Fixed arguments in example for TIFFRGBAImageGet()
        as per bug report by Patrick Connor.

2000-12-28  Frank Warmerdam  <warmerdam@pobox.com>

        * Added RELEASE-DATE file to release file list.

        * Fixed libtiff/makefile.vc to make tiffvers.h not version.h.

2000-12-22  Mike Welles <mike@bangstate.com>
        * added link to CVS mirror from index.html

        * updated html/internals.html to note that LZW compression is
          not supported by default.

2000-12-22  Frank Warmerdam  <warmerdam@pobox.com>

        * updated html/libtiff.html to not point at Niles' old JPL web site
        for the man pages, point at www.libtiff.org.

2000-12-21  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
        Leonard Rosenthol <leonardr@lazerware.com>.  May interfere
        with correct building on older systems.  If so, please let me know.

2000-12-19 Mike Welles <mike@bangsate.com>

        * Took out LZW Encoding from tif_lzw.c

        * Created HOWTO-RELEASE

        * Created html/v3.5.6.html

        * updated index.html

2000-12-01  Frank Warmerdam  <warmerdam@pobox.com>

        * Added patches for EOFB support in tif_fax3.c and tif_fax3.h.
        Patches supplied by Frank Cringle <fdc@cliwe.ping.de>
        Example file at: ftp://ftp.remotesensing.org/pub/libtiff/eofb_396.tif

2000-11-24  Frank Warmerdam  <warmerdam@pobox.com>

        * libtiff/Makefile.in: Added an installPrivateHdrs and install-private
        target so that the private headers required by libgeotiff can be
        installed with the others.  They are not installed by default.

        * libtiff/Makefile.in: Added @MACHLIBDEPS@ to LINUXdso and GNULDdso
        targets so libtiff.so will be built with an explicit dependency
        on libm.so.

        * libtiff/Makefile.in: Use softlinks to link libtiff.so.3 to
        libtiff.so.3.5.5.

        * libtiff/Makefile.in & configure: Remove all references to the ALPHA
        file, or ALPHA version logic.  Added stuff about DIST_POINT in
        place of DIST_TYPE and the alpha release number stuff.

2000-11-22  Frank Warmerdam  <warmerdam@pobox.com>

        * I have applied a patch from Steffen Moeller <moeller@ebi.ac.uk> to
        the configure script so that it now accepts the --prefix, and
        --exec-prefix directives.

2000-11-13  Frank Warmerdam  <warmerda@cs46980-c>

        * I have made a variety of modifications in an effort to ensure the
        TIFFLIB_VERSION macro is automatically generated from the RELEASE-DATE
        file which seems to be updated regularly.

         o mkversion.c now reads RELEASE-DATE and emits TIFFLIB_VERSION in
           version include file.
         o renamed version.h to tiffvers.h because we now have to install it
           with the public libtiff include files.
         o include tiffvers.h in tiffio.h.
         o updated tif_version.c to use tiffvers.h.
         o Updated Makefile.in accordingly.

        * As per http://bugzilla.remotesensing.org/show_bug.cgi?id=25
        I have updated the win32 detection rules in tiffcomp.h.

2000-10-20  Frank Warmerdam  <warmerda@cs46980-c>

        * tif_getimage.c: Fixed RGBA translation for YCbCr images for which
        the strip/tile width and height aren't multiples of the sampling size.
        See http://bugzilla.remotesensing.org/show_bug.cgi?id=20
        Some patches from Rick LaMont of Dot C Software.

        * Modified tif_packbits.c encoder to avoid compressing more
        data than provided if rowsize doesn't factor into provided data
        (such as occurs for YCbCr).

2000-10-19  Frank Warmerdam  <warmerda@cs46980-c>

        * tools/rgb2ycbcr.c: fixed output strip size to account for vertical
        roundup if rows_per_strip not a multiple of vertical sample size.

2000-10-16  Frank Warmerdam  <warmerda@cs46980-c>

        * tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
        as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
        from vandrove@vc.cvut.cz.

        * Modified tif_packbits.c decoding to avoid overrunning the
        output buffer, and to issue a warning if data needs to be
        discarded.  See http://bugzilla.remotesensing.org/show_bug.cgi?id=18

2000-10-12  Frank Warmerdam  <warmerda@cs46980-c>

        * Modified tiff2bw to ensure portions add to 100%, and that
        white is properly recovered.

        See bug http://bugzilla.remotesensing.org/show_bug.cgi?id=15
        Patch c/o Stanislav Brabec <utx@penguin.cz>

2000-09-30  Frank Warmerdam  <warmerda@cs46980-c>

        * Modified TIFFClientOpen() to emit an error on an attempt to
        open a comperessed file for update (O_RDWR/r+) access.  This is
        because the compressor/decompressor code gets very confused when
        the mode is O_RDWR, assuming this means writing only.  See
        bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13

2000-09-27  Frank Warmerdam  <warmerda@cs46980-c>

        * Added GNULDdso target an`d switched linux and freebsd to use it.

        * Applied patch for 0x0000 sequences in tif_fax3.h's definition
        of EXPAND1D() as per bug 11 (from Roman).

2000-09-25  Frank Warmerdam  <warmerda@cs46980-c>
        * Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
        cygwin compatibility.

        * Applied patch from Roman Shpount to tif_fax3.c.  This seems to
        be a proper fix to the buffer sizing problem.  See
        http://bugzilla.remotesensing.org/show_bug.cgi?id=11

        * Fixed tif_getimage.c to fix overrun bug with YCbCr images without
        downsampling.  http://bugzilla.remotesensing.org/show_bug.cgi?id=10
        Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
        bug and proving the patch.

2000-09-18  Frank Warmerdam  <warmerda@cs46980-c>

        * Fixed tif_jpeg.c so avoid destroying the decompressor before
        we are done access data thanks to bug report from:
        Michael Eckstein <eckstein@gepro.cz>.

        * Reverted tif_flush change.

2000-09-14  Frank Warmerdam  <warmerda@cs46980-c>

        * tif_flush.c: Changed so that TIFFFlushData() doesn't return an
        error when TIFF_BEENWRITING is not set.  This ensures that the
        directory contents can still be flushed by TIFFFlush().

2000-08-14  Frank Warmerdam  <warmerda@rommel.atlsci.com>

        * tif_open.c: Don't set MMAP for O_RDWR files.

        * tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
        so that files opened for update can be strip chopped too.

        * tif_read.c: fixed up bug with files missing rowsperstrip and
        the strips per separation fix done a few weeks ago.

2000-07-17  Frank Warmerdam  <warmerda@cs46980-c>

        * Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
        SAMPLEFORMAT_COMPLEXINT.

2000-07-13  Mike Welles <mike@onshore.com>

        * index.html, bugs.html: added bugzilla info.

2000-07-12  Frank Warmerdam  <warmerda@rommel.atlsci.com>

        * tif_read.c: fix subtle bug with determining the number of
        rows for strips that are the last strip in a separation but
        not the last strip of all in TIFFReadEncodedStrip().

        * Applied 16/32 bit fix to tif_fax3.c.  Fix supplied by
        Peter Skarpetis <peters@serendipity-software.com.au>

2000-06-15  Frank Warmerdam  <warmerda@rommel.atlsci.com>

        * Modified tiffio.h logic with regard to including windows.h.  It
        won't include it when building with __CYGWIN__.

2000-05-11  Frank Warmerdam  <warmerda@cs46980-c>

        * README: update to mention www.libtiff.org, don't list Sam's old
        email address.

        * configure: Fixed DSO test for Linux as per patch from
          Jan Van Buggenhout <chipzz@Ace.ULYSSIS.Student.KULeuven.Ac.Be>.

2000-04-21  Frank Warmerdam  <warmerda@rommel.atlsci.com>

        * libtiff/tif_dirread.c: Don't use estimate strip byte count for
        one tile/strip images with an offset, and byte count of zero. These
        could be "unpopulated" images.

2000-04-18  Frank Warmerdam  <warmerda@rommel.atlsci.com>

        * contrib/addtiffo: Added "averaging" resampling option.

        * tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT.

Tue Apr 18 16:18:08 2000  Frank Warmerdam  <warmerda@esabot.atlsci.com>

        * tools/Makefile.in: Modified to install properly on SGI.

2000-04-12  Mike Welles      <mike@onshore.com>

2000-04-04  Mike Welles      <mike@onshore.com>
        * tif_win32.c:  Applied patch to fix overreads and ovverwrites
          caught by BoundsChecker.  From Arvan Pritchard

        * Added contrib/stream (stream io) code submitted by Avi Bleiweiss.

2000-03-28  Frank Warmerdam  <warmerda@cs46980-c>    *** 3.5.5 release ***

        * fax2ps: Fixed mixup of width and height in bounding box statement
        as per submission by Nalin Dahyabhai <nalin@redhat.com>.

2000-03-27  Mike Welles      <mike@onshore.com>

        * fax2ps:  Modified printruns to take uint32 instead of uint16.

        (applied sed script s:/@:s;@:;s:/s;;:;: to configure).
        fix submitted to Stanislav Brabec <utx@k332.feld.cvut.cz>

        * tools/iptcutil was not in files list, and wasn't being
        added to tar archive.  Updated Makefile.in.

2000-03-17  Frank Warmerdam  <warmerda@cs46980-c>

        * tif_fax3.c: Fixed serious bug introduced during the uint16->uint32
        conversion for the run arrays.

2000-03-03  Frank Warmerdam  <warmerda@cs46980-c.mtnk1.on.wave.home.com>

        * Set td_sampleformat default to SAMPLEFORMAT_UINT instead of
        SAMPLEFORMAT_VOID in TIFFDefaultDirectory() in tif_dir.c.

        * Added "GetDefaulted" support for TIFFTAG_SAMPLEFORMAT in tif_aux.c.

        * Patched tif_fax3.c so that dsp->runs is allocated a bit bigger
        to avoid overruns encountered with frle_bug.tif.

Tue Feb 15 22:01:05 2000  Frank Warmerdam  <warmerda@gdal.velocet.ca>

        * Fixed tools/tiffcmp so that stopondiff testing works.

        * Modified tif_unix.c to support 2-4GB seeks if USE_64BIT_API is
          set to 1, and added default (off) setting in tiffconf.h.  This
          should eventually be set by the configure script somehow.

          The original work on all these 2-4GB changes was done by
          Peter Smith (psmith@creo.com).

        * Modified tif_win32.c to support 2-4GB seeks.

        * tentatively changed toff_t to be unsigned instead of signed to
          facilitate support for 2-4GB files.

        * Updated a variety of files to use toff_t.  Fixed some mixups
          between toff_t and tsize_t.

Fri Jan 28 10:13:49 2000  Frank Warmerdam  <warmerda@gdal.velocet.ca>

        * Largely reimplemented contrib/addtiffo to avoid temp files,
        updating the TIFF file in place.  Fixed a few other bugs to.

        * Set tif_rawdatasize to zero when freeing raw data buffer in
        TIFFWriteDirectory().

        * Enabled "REWRITE_HACK" in tif_write.c by default.

        * Fix bug in tif_write.c when switching between reading one directory
        and writing to another.

        * Made TIFFWriteCheck() public, and added TIFFCreateDirectory()

Wed Jan  5 12:37:48 2000  Frank Warmerdam  <warmerda@gdal.velocet.ca>

        * Added TIFFmemory(3t) functions to libtiff.def.

Tue Jan  4 13:39:00 2000  Frank Warmerdam  <warmerda@gdal.velocet.ca>

        * Added libtiff/libtiff.def to TIFFILES distribution list.

Mon Dec 27 12:13:39 EST 1999  Mike Welles <mike@onshore.com>

        * Created lzw compression kit, as a new module (libtiff-lzw-compression-kit).

        * Altered descriptions in tools to reflect "by default" lzw not supported

        * Updated index.html to note lzw compression kit.

Tue Dec 21 14:01:51 1999  Frank Warmerdam  <warmerda@gdal.velocet.ca>

        * Added fax3sm_winnt.c to distribution list in Makefile.in.

        * Aadded Pixar tag support.  Contributed by Phil Beffery <phil@pixar.com>

        * Made one more change to tif_dir.c for removal of LZW compression. Also added notice
          when LZW compression invoked.

        * Changed default compression in tools to TIFF_PACKBITS, and changed usage descriptions
          in tools to reflect removal of LZW compression

Mon Dec 20 18:39:02 EST 1999  Mike Welles  <mike@onshore.com>

        * Fixed bug that caused LZW (non) compression to segfault. Added
          warning about LZW compression removed being removed, and why.

        * Added nostrip to install in tools/Makefile.in so that debugging
          symbols are kept.

Tue Dec  7 12:04:47 EST 1999  Mike Welles  <mike@onshore.com>

        * Added patch from Ivo Penzar <ivo.penzar@infolink-software.com>,
