2016-11-11 Even Rouault <even.rouault at spatialys.com>

	* tools/tiffcrop.c: fix multiple uint32 overflows in
	writeBufferToSeparateStrips(), writeBufferToContigTiles() and
	writeBufferToSeparateTiles() that could cause heap buffer overflows.
	Reported by Henri Salo from Nixu Corporation.
	Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2592

2016-11-10 Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_strip.c: make TIFFNumberOfStrips() return the td->td_nstrips
	value when it is non-zero, instead of recomputing it. This is needed in
	TIFF_STRIPCHOP mode where td_nstrips is modified. Fixes a read outsize of
	array in tiffsplit (or other utilities using TIFFNumberOfStrips()).
	Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2587

2016-11-04 Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_predic.c: fix memory leaks in error code paths added in
	previous commit (fix for MSVR 35105)

2016-10-31 Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_predict.h, libtiff/tif_predict.c:
	Replace assertions by runtime checks to avoid assertions in debug mode,
	or buffer overflows in release mode. Can happen when dealing with
	unusual tile size like YCbCr with subsampling. Reported as MSVR 35105
	by Axel Souchet	& Vishal Chauhan from the MSRC Vulnerabilities & Mitigations
	team.

2016-10-26 Even Rouault <even.rouault at spatialys.com>

	* tools/fax2tiff.c: fix segfault when specifying -r without
	argument. Patch by Yuriy M. Kaminskiy.
	Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2572

2016-10-25 Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_dir.c: discard values of SMinSampleValue and
	SMaxSampleValue when they have been read and the value of
	SamplesPerPixel is changed afterwards (like when reading a
	OJPEG compressed image with a missing SamplesPerPixel tag,
	and whose photometric is RGB or YCbCr, forcing SamplesPerPixel
	being 3). Otherwise when rewriting the directory (for example
	with tiffset, we will expect 3 values whereas the array had been
	allocated with just one), thus causing a out of bound read access.
	Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2500
	(CVE-2014-8127, duplicate: CVE-2016-3658)

	* libtiff/tif_dirwrite.c: avoid null pointer dereference on td_stripoffset
	when writing directory, if FIELD_STRIPOFFSETS was artificially set
	for a hack case	in OJPEG case.
	Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2500
	(CVE-2014-8127, duplicate: CVE-2016-3658)

2016-10-25 Even Rouault <even.rouault at spatialys.com>

	* tools/tiffinfo.c: fix out-of-bound read on some tiled images.
	(http://bugzilla.maptools.org/show_bug.cgi?id=2517)

	* libtiff/tif_compress.c: make TIFFNoDecode() return 0 to indicate an
	error and make upper level read routines treat it accordingly.
	(linked to the test case of http://bugzilla.maptools.org/show_bug.cgi?id=2517)

2016-10-14 Even Rouault <even.rouault at spatialys.com>

	* tools/tiffcrop.c: fix out-of-bound read of up to 3 bytes in

	& Vishal Chauhan from the MSRC Vulnerabilities & Mitigations team.

2016-10-09 Even Rouault <even.rouault at spatialys.com>

	* tools/tiff2pdf.c: fix write buffer overflow of 2 bytes on JPEG
	compressed images. Reported by Tyler Bohan of Cisco Talos as
	TALOS-CAN-0187 / CVE-2016-5652.
	Also prevents writing 2 extra uninitialized bytes to the file stream.

2016-10-08 Even Rouault <even.rouault at spatialys.com>

	* tools/tiffcp.c: fix out-of-bounds write on tiled images with odd
	tile width vs image width. Reported as MSVR 35103
	by Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities &
	Mitigations team.

2016-10-08 Even Rouault <even.rouault at spatialys.com>

	* tools/tiff2pdf.c: fix read -largely- outsize of buffer in
	t2p_readwrite_pdf_image_tile(), causing crash, when reading a
	JPEG compressed image with TIFFTAG_JPEGTABLES length being one.
	Reported as MSVR 35101 by Axel Souchet and Vishal Chauhan from
	the MSRC Vulnerabilities & Mitigations team.

2016-10-08 Even Rouault <even.rouault at spatialys.com>

	* tools/tiffcp.c: fix read of undefined variable in case of missing
	required tags. Found on test case of MSVR 35100.
	* tools/tiffcrop.c: fix read of undefined buffer in
	readContigStripsIntoBuffer() due to uint16 overflow. Probably not a
	security issue but I can be wrong. Reported as MSVR 35100 by Axel
	Souchet from the MSRC Vulnerabilities & Mitigations team.

2016-09-25  Bob Friesenhahn  <[email protected]>

	* html: Change as many remotesensing.org broken links to a working
	URL as possible.

2016-09-24  Bob Friesenhahn  <[email protected]>

	* libtiff/tif_predict.c (PredictorSetup): Enforce bits-per-sample
	requirements of floating point predictor (3).  Fixes CVE-2016-3622
	"Divide By Zero in the tiff2rgba tool."

2016-09-23 Even Rouault <even.rouault at spatialys.com>

	* tools/tiffcrop.c: fix various out-of-bounds write vulnerabilities
	in heap or stack allocated buffers. Reported as MSVR 35093,
	MSVR 35096 and MSVR 35097. Discovered by Axel Souchet and Vishal
	Chauhan from the MSRC Vulnerabilities & Mitigations team.
	* tools/tiff2pdf.c: fix out-of-bounds write vulnerabilities in
	heap allocate buffer in t2p_process_jpeg_strip(). Reported as MSVR
	35098. Discovered by Axel Souchet and Vishal Chauhan from the MSRC
	Vulnerabilities & Mitigations team.
	* libtiff/tif_pixarlog.c: fix out-of-bounds write vulnerabilities
	in heap allocated buffers. Reported as MSVR 35094. Discovered by
	Axel Souchet and Vishal Chauhan from the MSRC Vulnerabilities &
	Mitigations team.
	* libtiff/tif_write.c: fix issue in error code path of TIFFFlushData1()
	that didn't reset the tif_rawcc and tif_rawcp members. I'm not
	completely sure if that could happen in practice outside of the odd
	behaviour of t2p_seekproc() of tiff2pdf). The report points that a
	better fix could be to check the return value of TIFFFlushData1() in
	places where it isn't done currently, but it seems this patch is enough.
	Reported as MSVR 35095. Discovered by Axel Souchet & Vishal Chauhan &
	Suha Can from the MSRC Vulnerabilities & Mitigations team.

	offsets on a even offset (affects BigTIFF). This was a regression of the
	changeset of 2015-10-19.

2015-12-12  Even Rouault <even.rouault at spatialys.com>

	compiler warning.
	(TIFF_INT64_MAX): Avoid use of platform-specific large constants.
	(TIFF_UINT32_MAX): Avoid use of platform-specific large constants.

2015-09-01  Bob Friesenhahn  <[email protected]>

	* Makefile.am (distcheck-hook), configure.ac: Applied patches by
	Roger Leigh (via tiff mailing list on 2015-09-01) to fix issue
	with BSD make and to make use of cmake in 'distcheck' target
	conditional on if cmake is available.

	* CMakeLists.txt, Makefile.am, configure.ac: Applied patches by
	Roger Leigh (via tiff mailing list on 2015-09-01).

	CMake build is now included in 'distcheck' target.

	Builds with CMake 2.8.9 and newer.

	Tar is now resquested to use POSIX PAX format.

2015-08-31  Bob Friesenhahn  <[email protected]>

	* 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>

	* libtiff/tif_predict.c: pedantic change to add explicit masking
	with 0xff before casting to uchar in floating-point horizontal
	differencing and accumulation routines.

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

	* libtiff/tif_predict.c: fix generation of output with 16 bit
	or 32 bit integer, when byte swapping is needed, in
	horizontal predictor (#2521). Also fixes decoding when there is
	a single pixel to code (unlikely case...) and byte swapping is
	involved.

2015-08-30  Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_lzw.c: make nextdata a unsigned type to avoid
	undefined behaviour with shifts (gcc -fsanitize=shift)

2015-08-30  Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_fax3.c, libtiff/tif_lzw.c, libtiff/tif_predict.c:
	add explicit masking with 0xff before casting
	to unsigned char (make icc -check=conversions happy)

	* libtiff/tif_predict.c: operate on unsigned datatypes when
	computing/applying differences to avoid undefined behaviour of
	signed types (C standard compliance)

2015-08-30  Bob Friesenhahn  <[email protected]>

	* configure.ac: libtiff 4.0.5 released.

2015-08-29  Bob Friesenhahn  <[email protected]>

	* CMakeLists.txt: Applied patch by Roger Leigh (via tiff mailing
	list on 2015-08-29) to add ld-version-script option to cmake build
	to match autoconf.  Note: defaults to 'on' to be ABI-compatible by
	default with common Linux distribution builds.  Note that the
	autoconf configure script defaults to 'off'.

	* html/build.html: Applied patch by Roger Leigh (via tiff mailing
	list on 2015-08-29) to describe how to use CMake to build libtiff.

2015-08-28  Bob Friesenhahn  <[email protected]>

	* html/v4.0.5.html: Added HTML file describing the changes which
	will appear in the 4.0.5 release.

2015-08-23  Bob Friesenhahn  <[email protected]>

	* 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.

	* tools/fax2tiff.c (main): Eliminate a compiler warning in 64-bit
	builds about cast to thandle_t.

	* test/rewrite_tag.c (main): Does not require any arguments.

2015-08-20  Bob Friesenhahn  <[email protected]>

	* tools/CMakeLists.txt, port/snprintf.c: Patch by Roger Leigh to
	fix build issues when using Cmake due to Windows large file
	changes.

2015-08-18  Bob Friesenhahn  <[email protected]>

	* libtiff/tiffiop.h: First cut at supporting large files under
	Microsoft Windows using tif_unix.c and the libtiff tools.  This
	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.

2015-08-15  Bob Friesenhahn  <[email protected]>

	* libtiff/tif_jpeg.c: Applied patch by Räisä Olli to assure that
	client_data is initialized to a known value, and to report an

	* configure.ac: Add a HAVE_FOO Automake conditional for each
	add-on library.

	* test/Makefile.am (JPEG_DEPENDENT_CHECK_PROG): raw_decode
	requires JPEG support to compile.  Use Automake conditional to

	* 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,

	* 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.

2014-11-20  Even Rouault  <[email protected]>
	* libtiff/tif_jpeg.c: fix segfault in JPEGFixupTagsSubsampling() on
	corrupted image where tif->tif_dir.td_stripoffset == NULL (bug #2471)

2014-11-20  Even Rouault  <[email protected]>
	* automake: updated to 1.14.1
	* libtool: updated to 2.4.3
	* HOWTO-RELEASE: small update about autotools building order

2014-10-20  Olivier Paquet  <[email protected]>
	* tools/tiff2pdf.c: Preserve input file directory order when pages
	are tagged with the same page number.

2014-08-31  Bob Friesenhahn  <[email protected]>

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

2014-06-07  Bob Friesenhahn  <[email protected]>

	* tools/tiff2rgba.c (]): Fixed tiff2rgba usage message in that zip
	was wrongly described.  Fix suggested by Miguel Medalha.

2014-05-06  Bob Friesenhahn  <[email protected]>

	* libtiff/tif_dirinfo.c (TIFFField) : Fix data type for
	TIFFTAG_GLOBALPARAMETERSIFD tag.  Patch by Steve Underwood.
	Reviewed and forwarded by Lee Howard.

2013-11-30  Frank Warmerdam  <[email protected]>

	* libtiff/tif_dir.c: fix last fix for TIFFNumberOfDirectories()

2013-10-21  Frank Warmerdam  <[email protected]>

	* libtiff/tif_dir.c: generate error in case of directory count
	overflow.

2013-10-01  Frank Warmerdam  <[email protected]>

	* libtiff/tiff.h, libtiff/tif_dirinfo.c: add definitions for
	TIFF/EP CFARepeatPatternDim and CFAPattern tags (bug #2457)

2013-09-12  Bob Friesenhahn  <[email protected]>

	* libtiff/tif_dir.c (TIFFAdvanceDirectory): If nextdir is found to
	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.

2013-08-14  Frank Warmerdam  <[email protected]>

	* tools/gif2tiff.c: fix possible OOB write (#2452, CVE-2013-4244)

2013-08-13  Frank Warmerdam  <[email protected]>

	* tools/gif2tiff.c: Be more careful about corrupt or
	hostile input files (#2450, CVE-2013-4231)

	* tools/tiff2pdf.c: terminate after failure of allocating
	ycbcr buffer (bug #2449, CVE-2013-4232)

2013-07-09  Frank Warmerdam  <[email protected]>

	* tools/tiffinfo.c: Default various values fetched with
	TIFFGetField() to avoid being uninitialized.

2013-05-02  Tom Lane  <[email protected]>

	* 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  <[email protected]>

	* contrib/dbs/xtiff/xtiff.c, libtiff/tif_codec.c,
 	libtiff/tif_dirinfo.c, tools/rgb2ycbcr.c, tools/tiff2bw.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  <[email protected]>

	* configure.ac: Applied patch by Brad Smith to improve pkg-config
	static linking by adding -lm to Libs.private when needed.

2013-03-05  Tom Lane  <[email protected]>

	* html/man/tiff2ps.1.html, html/man/tiffcp.1.html,
 	html/man/tiffdither.1.html, man/tiff2ps.1, man/tiffcp.1,
 	man/tiffdither.1, tools/tiff2ps.c, tools/tiffcp.c,
 	tools/tiffdither.c: Sync tool usage printouts and man pages with
 	reality (quite a few options had escaped being documented in one
 	or both places).  Per an old report from Miroslav Vadkerti.

2013-01-25  Bob Friesenhahn  <[email protected]>

	* tools/tiff2ps.c:Fix bug in auto rotate option code. Once a
	rotation angle was set by the auto rotate check, it was retained
	for all pages that followed instead ofa being retested for each
	page.  Patch by Richard Nolde.

2013-01-18  Frank Warmerdam  <[email protected]>

	* libtiff/tif_write.c: tmsize_t related casting warning fixed for
	64bit linux.

	* libtiff/tif_read.c: uint64/tmsize_t change for MSVC warnings.
	http://bugzilla.maptools.org/show_bug.cgi?id=2427

2012-12-20  Tom Lane  <[email protected]>

	* 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.)

2012-12-12  Tom Lane  <[email protected]>

	* libtiff/tif_print.c: Fix TIFFPrintDirectory's handling of
	field_passcount fields: it had the TIFF_VARIABLE and
	TIFF_VARIABLE2 cases backwards.

2012-12-10  Tom Lane  <[email protected]>

	* tools/ppm2tiff.c: Improve previous patch for CVE-2012-4564:
 	check the linebytes calculation too, get the max() calculation
 	straight, avoid redundant error messages, check for malloc
 	failure.

2012-12-10  Tom Lane  <[email protected]>

	* libtiff/tif_pixarlog.c: Improve previous patch for CVE-2012-4447
 	(to enlarge tbuf for possible partial stride at end) so that
 	overflow in the integer addition is detected.  Per gripe from
 	Huzaifa Sidhpurwala.

2012-12-03  Bob Friesenhahn  <[email protected]>

	* tools/tiffset.c: tiffset now supports a -u option to unset a
	tag.  Patch by Zach Baker. See
	http://bugzilla.maptools.org/show_bug.cgi?id=2419

2012-11-18  Bob Friesenhahn  <[email protected]>

	* automake: Update Automake to 1.12.5 release.

	* libtiff/tif_{unix,vms,win32}.c (_TIFFmalloc): ANSI C does not
	require malloc() to return NULL pointer if requested allocation
	size is zero.  Assure that _TIFFmalloc does.

2012-11-01  Frank Warmerdam  <[email protected]>

	* tools/ppm2tiff.c: avoid zero size buffer vulnerability.
	CVE-2012-4564 - Thanks to Huzaifa Sidhpurwala of the
	Red Hat Security Response team for the fix.

2012-10-18  Frank Warmerdam  <[email protected]>

	* tif_zip.c: Avoid crash on NULL error messages.

	* Makefile.am: Update to Automake 1.12.4

2012-08-19  Bob Friesenhahn  <[email protected]>

	* Makefile.in: Update to Automake 1.12.3

	* 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  <[email protected]>

	* libtiff/tif_write.c: Fix bug rewriting image tiles in a
	compressed file: http://trac.osgeo.org/gdal/ticket/4771

2012-08-02  Frank Warmerdam  <[email protected]>

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

2012-07-26  Tom Lane  <[email protected]>

	* 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  <[email protected]>

	* 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 [email protected]

2012-07-18  Tom Lane  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2012-07-02  Frank Warmerdam  <[email protected]>

	* libtiff/tif_jpeg.c: Fix handling when writing RGBA jpeg compressed
	imagery (http://trac.osgeo.org/gdal/ticket/4732)

2012-06-20  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

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

2012-06-15  Frank Warmerdam  <[email protected]>

	*  libtiff 4.0.2 released.

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

2012-06-15  Tom Lane  <[email protected]>

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

2012-06-12  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2012-03-30  Frank Warmerdam  <[email protected]>

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

2012-02-18  Bob Friesenhahn  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff 4.0.0 released.

2011-12-08  Frank Warmerdam  <[email protected]>

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

2011-12-07  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff/libtiff.def: Restore TIFFMergeFieldInfo.

2011-05-31  Jim Meyering  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff 4.0.0beta7 released.

2011-04-09  Bob Friesenhahn  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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).
	http://bugzilla.maptools.org/show_bug.cgi?id=2300

2011-03-10  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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.

	http://bugzilla.maptools.org/show_bug.cgi?id=2295

2011-02-22  Frank Warmerdam  <[email protected]>

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

2011-02-18  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* libtiff/tif_print.c: remove unused variable.

2011-02-09  Frank Warmerdam  <[email protected]>

2011-01-24  Olivier Paquet  <[email protected]>

	* libtiff/{tif_dir.{h,c}, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c,
	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.

	* 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.

2010-07-13  Bob Friesenhahn  <[email protected]>

	* tools/tiffcrop.c: Patch from Richard Nolde to avoid a
	potentially unterminated buffer due to using an exceptionally long
	file name.

2010-07-08  Andrey Kiselev  <[email protected]>

	* tools/tiff2pdf.c: Fixed ID buffer filling in
	t2p_write_pdf_trailer(), thanks to Dmitry V. Levin.

2010-07-07  Andrey Kiselev  <[email protected]>

	* 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  <[email protected]>

	* tools/tiffset.c: Properly handle TIFFTAG_PAGENUMBER,
	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  <[email protected]>

	* 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
	WhitePoint tag as per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2042

	* libtiff/tif_getimage.c: Check the number of samples per pixel when
	working with YCbCr image in PickContigCase(). As per bug
	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  <[email protected]>

	* tools/tiffgt.c: Properly check the raster buffer allocations for

	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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2010-06-09  Bob Friesenhahn  <[email protected]>

	* 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  <[email protected]>

	* 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 <[email protected]>

	* 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  <[email protected]>

	* 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).
	http://bugzilla.maptools.org/show_bug.cgi?id=2192

2010-05-07  Frank Warmerdam  <[email protected]>

	* 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.
	http://trac.osgeo.org/gdal/ticket/3539

2010-05-06  Andrey Kiselev  <[email protected]>

	* html/man/TIFFGetField.3tiff.html, html/man/TIFFSetField.3tiff.html:
	Regenerated from the source.

2010-05-05  Olivier Paquet  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff/tif_jpeg.c: avoid preparing jpeg tables everytime
	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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff 4.0.0alpha5 released.

2009-11-03  Bob Friesenhahn  <[email protected]>

	* tools/tiffcrop.c: Updated tiffcrop from Richard Nolde.  This
	version has undergone substantial testing with arbitrary sample

	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 -

	* html/tools.html: Add manual page links, and a summary
	description of tiffcrop.

2009-10-07  Bob Friesenhahn  <[email protected]>

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

2009-09-24  Bob Friesenhahn  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff 4.0.0alpha4 released.

	* HOWTO-RELEASE: Improved release instructions.

2009-08-23  Bob Friesenhahn  <[email protected]>

	* 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.

	http://bugzilla.maptools.org/show_bug.cgi?id=1917

2008-08-12  Edward Lam  <[email protected]>

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

2008-07-29  Frank Warmerdam  <[email protected]>

	* tif_strip.c: Replace assertions related to samplesperpixel != 3 or
	the subsampling values not being 1, 2 or 4 (for jpeg compressed images)

	* li2008-04-15  Andrey Kiselev  <[email protected]>

btiff/tif_win32.c: Replace custom Win32 memory api with generic

2008-05-18  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2008-04-10  Andrey Kiselev  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2008-01-01  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2007-11-23  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

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

2007-11-02  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2007-10-22  Joris Van Damme  <[email protected]>

	* 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  <[email protected]>

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

2007-10-05  Frank Warmerdam  <[email protected]>

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

2007-09-29  Joris Van Damme  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2007-09-20  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2007-08-10  Joris Van Damme  <[email protected]>

	* libtiff/tif_win32.c: use SetFilePointer instead of

	formatter instead of "%lld" with MSVC compiler.

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

2007-07-18  Andrey Kiselev  <[email protected]>

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

	* 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,

	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  <[email protected]>

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

	by Leon Bottou.

2007-06-26  Bob Friesenhahn  <[email protected]>

	* configure.ac: Fix typo when substituting value for unsigned 8 bit type.

	* libtiff/tiffconf.vc.h: Add porting type defintions for WIN32.

2007-06-25  Bob Friesenhahn  <[email protected]>

	* 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

	* 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  <[email protected]>

	* 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  <[email protected]>

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

2007-04-06  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

	* {configure.ac, libtiff/tif_config.h.vc, libtiff/tif_jbig.c}
	(JBIGDecode): jbg_newlen is not available in older JBIG-KIT and

	- Bugfix of handling of 16bit RGB with unassociated alpha

2006-04-11  Joris Van Damme  <[email protected]>

	* libtiff/tif_getimage.c:
	- When there is no alpha, gtTileSeparate and gtStripSeparate allocated

	  Removed allocation and fill.
	- Minor rename of vars in gtTileSeparate and gtStripSeparate
	  anticipating planned functionality extension

2006-04-08  Joris Van Damme  <[email protected]>

	of inappropriate use of jpeg_abort instead of jpeg_destroy

2006-04-07  Joris Van Damme  <[email protected]>

	* libtiff/tif_getimage.c: replaced usage of TIFFScanlineSize in
	gtStripContig with TIFFNewScanlineSize so as to fix buggy behaviour

	YCbCr and desubsampling

2006-03-29  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

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

	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.

	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  <[email protected]>

	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  <[email protected]>

	* 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.

	COMPRESSION_LZW with COMPRESSION_NONE in _TIFFVSetField().

	* Removed Makefile, tools/Makefile, port/install.sh, man/Makefile

	http://bugzilla.remotesensing.org/show_bug.cgi?id=75

2001-08-28  Frank Warmerdam  <[email protected]>

	* libtiff/tif_getimage.c: Don't complain for CMYK (separated)

	force use of uint32 counts instead of short counts.

	* libtiff/tif_dirwrite.c: Added support for TIFF_VARIABLE2 in the
	case of writing TIFF_BYTE/TIFF_SBYTE fields.

	providing for MacOS X support.

2001-03-29  Frank Warmerdam  <[email protected]>

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

2001-03-28  Frank Warmerdam  <[email protected]>

	* 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 practially
	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  <[email protected]>

	* libtiff/tiffio.h: Changed "#if LOGLUV_PUBLIC" to

	* 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
	([email protected]).  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  <[email protected]>

	* 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 <[email protected]>

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

2001-01-07  Frank Warmerdam  <[email protected]>

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

2000-12-28  Frank Warmerdam  <[email protected]>

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

2000-12-22  Mike Welles <[email protected]>
        * 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  <[email protected]>

	* 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  <[email protected]>

	* libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
	Leonard Rosenthol <[email protected]>.  May interfere

	Example file at: ftp://ftp.remotesensing.org/pub/libtiff/eofb_396.tif

2000-11-24  Frank Warmerdam  <[email protected]>

	* 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  <[email protected]>

	* I have applied a patch from Steffen Moeller <[email protected]> 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.

	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>

	Patch c/o Stanislav Brabec <[email protected]>

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>

	* Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
	cygwin compatibility.

	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

	* 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  <[email protected]>

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

	Peter Skarpetis <[email protected]>

2000-06-15  Frank Warmerdam  <[email protected]>

	* Modified tiffio.h logic with regard to including windows.h.  It
