	Merge branch 'no_sprintf' into 'master'
	Replace sprintf calls with snprintf

	See merge request libtiff/libtiff!408

2022-11-08  Mark Mentovai  <mark@chromium.org>

	Replace sprintf calls with snprintf.
	This makes it possible to build libtiff without warnings using the macOS
	13 SDK. Calls to sprintf are replaced with snprintf, passing appropriate
	buffer sizes.

	It doesn’t appear that any of the changed uses of sprintf were actually
	unsafe, so no behavior change is expected aside from SDK compatibility.

	The macOS 13 SDK deprecates sprintf as it’s difficult to use safely. The
	deprecation warning message is visible when building C++, but it is not
	normally visible when building plain C code due to a quirk in how
	sprintf is declared in the SDK. However, the deprecation message is
	visible when building plain C under Address Sanitizer
	(-fsanitize=address). This discrepancy was discovered at
	https://crbug.com/1381706 and reported to Apple with a copy at
	https://openradar.appspot.com/FB11761475.

	The macOS 13 SDK is packaged in Xcode 14.1, released on 2022-11-01. This
	also affects the iOS 16 SDK and other 2022-era Apple OS SDKs packaged in
	Xcode 14.0, released on 2022-09-12.

	libtiff is visible to the Chromium build via PDFium, and this change is
	needed to allow Chromium to move forward to the macOS 13 SDK.

	This change is limited to the libtiff directory. Other uses of sprintf
	were found in contrib, test, and tools.

	Merge branch 'reentrant' into 'master'

	TIFFReadRGBATileExt(): fix (unsigned) integer overflow on strips/tiles > 2 GB
	Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=53137

2022-11-08  Laramie Leavitt  <lar@google.com>

	Add reentrant error functions.
	Prior to this change, libtiff relied on global error handlers,
	which is problematic when libtiff used by multiple independent
	libraries from within the same process, as they may unwittingly
	clobber the error handling, introduce race conditions when setting
	handlers, or otherwise have unintended side effects.

	This change adds error handlers to the TIFF struct, which are
	used preferentially when available. The error handlers are invoked
	when the re-entrant error functions are called:

	void TIFFErrorExtR(TIFF*, const char* module, const char* fmt, ...)
	void TIFFWarningExtR(TIFF*, const char* module, const char* fmt, ...)

	The handlers have a similar signature to the existing extended
	handlers, additionally returning an int:

	int TIFFErrorHandlerExtR(thandle_t, const char*, const char*, va_list)

	 thandle_t is the userdata passed to TIFFOpen
	 When the handler returns 1, the global handlers are not called.

	Custom error/warning handlers may be installed on a per-file
	basis by calling the Set functions:

	  TIFF* tif = TIFFOpen(...);
	  TIFFSetErrorHandlerExtR(tif, MyErrorHandler);
	  TIFFSetWarningHandlerExtR(tif, MyWarningHandler);

	Additionally, the callsites to TIFFErrorExt and TIFFWarningExt
	have been updated to call the reentrant versions.

	Improved IFD-Loop Handling (fixes #455)
	IFD infinite looping was not fixed by MR 20 (see #455).
	An improved IFD loop handling is proposed.

	Basic approach:

	- The order in the entire chain must be checked, and not only whether an offset has already been read once.
	- To do this, pairs of directory number and offset are stored and checked.
	- The offset of a directory number can change.
	- TIFFAdvanceDirectory() must also perform an IFD loop check.
	- TIFFCheckDirOffset() is replaced by _TIFFCheckDirNumberAndOffset().

	Rules for the check:

	- If an offset is already in the list, it must have the same IFD number. Otherwise it is an IDF loop.
	- If the offset is not in the list and the IFD number is greater than there are list entries, a new list entry is added.
	- Otherwise, the offset of the IFD number is updated.

	Reference is also made to old bugzilla bug 2772 and MR 20, which did not solve the general issue.
	This MR closes #455

	Fix CMake build to be compatible with FetchContent.
	Recent versions of CMake have improved support for including
	dependencies, using the FetchContent module, which allows a dependency
	to be imported as a subproject and then later found automatically by
	calls to `find_package`.

	This change makes libtiff's CMake better behaved when used as a
	sub-project:

	- CMake has a single global namespace for all target names in all
	  sub-projects.  This commit renames the following CMake targets:

	  - port -> tiff_port
	  - mkg3states -> tiff_mkg3states
	  - faxtable -> tiff_faxtable
	  - release -> tiff_release

	- When building TIFF as a sub-project, it is not normally useful to
	  create install rules for its targets.  This commit adds a
	  `tiff-install` option that controls whether the install rules are
	  added and defaults to OFF when libtiff is included as a sub-project.

	- Previously, libtiff set `BUILD_SHARED_LIBS` to ON by default.  With
	  this commit, that default is only set if libtiff is the top-level
	  project.

	- When using `find_package(TIFF)`, the targets `TIFF::TIFF` and
	  `TIFF::CXX` are defined.  This commit makes libtiff itself define
	  those targets as aliases, to allow other cmake projects to use
	  either `find_package` or `FetchContent` interchangeably.

	- Adds ZSTD_HAVE_DECOMPRESS_STREAM variable which may be set to bypass
	  `check_symbol_exists` call.  Fixes
	  https://gitlab.com/libtiff/libtiff/-/issues/472.

	Revised handling of TIFFTAG_INKNAMES and related TIFFTAG_NUMBEROFINKS value
	In order to solve the buffer overflow issues related to TIFFTAG_INKNAMES and related TIFFTAG_NUMBEROFINKS value, a revised handling of those tags within LibTiff is proposed:

	Behaviour for writing:
	    `NumberOfInks`  MUST fit to the number of inks in the `InkNames` string.
	    `NumberOfInks` is automatically set when `InkNames` is set.
	    If `NumberOfInks` is different to the number of inks within `InkNames` string, that will be corrected and a warning is issued.
	    If `NumberOfInks` is not equal to samplesperpixel only a warning will be issued.

	Behaviour for reading:
	    When reading `InkNames` from a TIFF file, the `NumberOfInks` will be set automatically to the number of inks in `InkNames` string.
	    If `NumberOfInks` is different to the number of inks within `InkNames` string, that will be corrected and a warning is issued.
	    If  `NumberOfInks` is not equal to samplesperpixel only a warning will be issued.

	This allows the safe use of the NumberOfInks value to read out the InkNames without buffer overflow

	This MR will close the following issues:  #149, #150, #152, #168 (to be checked), #250, #269, #398 and #456.

	It also fixes the old bug at http://bugzilla.maptools.org/show_bug.cgi?id=2599, for which the limitation of `NumberOfInks = SPP` was introduced, which is in my opinion not necessary and does not solve the general issue.

	tiffcrop: disable incompatibility of -Z, -X, -Y, -z options with any PAGE_MODE_x option (fixes #411 and #413)
	tiffcrop does not support –Z, -z, -X and –Y options together with any other PAGE_MODE_x options like  -H, -V, -P, -J, -K or –S.

	Code analysis:

	With the options –Z, -z, the crop.selections are set to a value > 0. Within main(), this triggers the call of processCropSelections(), which copies the sections from the read_buff into seg_buffs[].
	In the following code in main(), the only supported step, where that seg_buffs are further handled are within an if-clause with  if (page.mode == PAGE_MODE_NONE) .

	Execution of the else-clause often leads to buffer-overflows.

	Therefore, the above option combination is not supported and will be disabled to prevent those buffer-overflows.

	The MR solves issues #411 and #413.

	CLIPPATH tags defined twice but differently and also wrongly.
	In tif_dirinfo.c the tags for clippath are wrongly defined and the tag TIFFTAG_XCLIPPATHUNITS is even different twice. Therefore, those tags cannot be written / read correctly and may even lead to buffer overflow.
	E.g.: In the case of TIFFSetField(YCLIPPATHUNITS), a 1 byte storage space is allocated because of TIFF_SETGET_UNDEFINED, in which an  int32_t value should be stored because of TIFF_SLONG type definition. Then, an int32_t value is read from that 1 byte storage location.

	The current definition is:

	{ TIFFTAG_CLIPPATH, -1, -3, TIFF_BYTE, 0, TIFF_SETGET_UNDEFINED, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 1, "ClipPath", NULL },
	{ TIFFTAG_XCLIPPATHUNITS, 1, 1, TIFF_SLONG, 0, TIFF_SETGET_UNDEFINED, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "XClipPathUnits", NULL },
	{ TIFFTAG_XCLIPPATHUNITS, 1, 1, TIFF_SBYTE, 0, TIFF_SETGET_UNDEFINED, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "XClipPathUnits", NULL },
	{ TIFFTAG_YCLIPPATHUNITS, 1, 1, TIFF_SLONG, 0, TIFF_SETGET_UNDEFINED, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "YClipPathUnits", NULL },

	Whereas the correct definition according to TIFF Specification Supplement 1 (https://www.awaresystems.be/imaging/tiff/specification/TIFFPM6.pdf) should be:

	{ TIFFTAG_CLIPPATH, -3, -3, TIFF_BYTE, 0, TIFF_SETGET_C32_UINT8, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 1, "ClipPath", NULL },
	{ TIFFTAG_XCLIPPATHUNITS, 1, 1, TIFF_LONG, 0, TIFF_SETGET_UINT32, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "XClipPathUnits", NULL },
	{ TIFFTAG_YCLIPPATHUNITS, 1, 1, TIFF_LONG, 0, TIFF_SETGET_UINT32, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "YClipPathUnits", NULL },

	Also the set_get_field of the following tag should be corrected from

	{ TIFFTAG_INTEROPERABILITYIFD, 1, 1, TIFF_IFD8, 0, TIFF_SETGET_UNDEFINED, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "InteroperabilityIFDOffset", NULL },
	to
	{ TIFFTAG_INTEROPERABILITYIFD, 1, 1, TIFF_IFD8, 0, TIFF_SETGET_IFD8, TIFF_SETGET_UNDEFINED, FIELD_CUSTOM, 0, 0, "InteroperabilityIFDOffset", NULL },

	However, if those tags schould not be handled by LibTiff because they are deamed as abandoned or unwanted tags, those tags need to be defined with FIELD_IGNORE instead of FIELD_CUSTOM and keeping set_field_type  = TIFF_SETGET_UNDEFINED

2022-07-01  Su_Laus  <sulau@freenet.de>

	In tif_dirinfo.c the definition for TIFFTAG_COMPRESSION has different settings of  field_readcount=TIFF_VARIABLE (-1) and field_writecount=1. The tag is defined with Count=1, thus field_readcount is wrong and should also be 1. Although TIFFTAG_BITSPERSAMPLE is defined with Count:N=SamplesPerPixel, only ONE uint16_t value is passed with TIFFSetField() and TIFFGetField(). However, an array with N=SamplesPerPixel equal values is written into the TIFF file. Shouldn't field_readcount = field_writecount = 1 then?  The behaviour of TiffLib does not change, because the handling is coded directly.

2022-06-04  Brian Ledger  <brian.peter.ledger@gmail.com>

	Include stdlib.h in tif_lzw.c.
	In `tif_lzw.c`, a call is made to `_byteswap_uint64`. This is declared in `stdlib.h`. `stdlib.h` is not included in `tib_lzw.c`, so a name error may occur.

	This change adds `#include stdlib.h` to `tif_lzw.c`, to prevent a name error from occuring when `stdlib.h` is not included.

2022-05-15  Alex Richardson  <alexrichardson@google.com>

	cmake: allow running the tests with a read-only source directory.
	Prior to this commit CTest would invoke all simple_tests tests with the
	current working directory set to the source directory. However, some of
	the tests (e.g. rewrite) will output files to the current working
	directory and will therefore fail when run with a read-only source
	directory. This can happen e.g. when testing a cross-compiled version of
	libtiff where the sources are mounted read-only in the virtual machine.

	Simply changing the working directory to CMAKE_CURRENT_BINARY_DIR allows
	all but raw_decode to pass. The raw_decode test looks for files in the
	source directory, and uses the `srcdir` environment variable to find, so
	we also have to add a set_tests_properties() call to specify that env var.

2022-02-19  Even Rouault  <even.rouault@spatialys.com>

	TIFFClientOpen(): remove useless initializations of tif_rawcc and tif_flags after TIFFReadDirectory()
	Those initializations date back to the initial commit of libtiff, but I
	strongly suspect there are no longer needed those days.
	Setting tif_rawcc to (tmsize_t)-1 is weird. AFAICS, nowhere else in the library
	-1 is used as a special markeri for that field. Immediately after TIFFReadDirectory()
	returns it is set to 0, and this is the value used in tif_read.c/tif_write.c to
	reset it.
	And setting the TIFF_BUFFERSETUP bit of tif_flags is even more
	suspicious as the only place where it is set otherwise is in
	TIFFWriteBufferSetup(). I suspect this bogus setting of the flag was the
	reason for commit dbf2339a1 where BUFFERCHECK() in addition to checking
	the bit also checked the tif_rawdata against nullptr.

	If setting those 2 fields was needed, it would mean that TIFFClientOpen() with the
	'h' hint to disable automatic TIFFReadDirectory() would be broken,
	because someone issuing a manual TIFFReadDirectory() couldn't set them,
	as being private members.

	The libtiff test suite is happy with that change, and the GDAL one too.

	tif_dirwrite.c: Fix TIFFRewriteDirectory discarding directories.
	This fixes a bug caused by the `tif_lastdiroff` optimization when
	rewriting directories.

	Rewriting the Nth directory temporarily zeroes the pointer to it
	(located in the N-1th directory) and relies on `TIFFLinkDirectory`
	traversing the whole directory list to find the zeroed pointer and
	linking the rewritten directory to it. Since `TIFFLinkDirectory` skips
	the traversal when `tif_lastdiroff` is set, this change unsets it
	to force the full traversal when rewriting a directory.

	A test to catch this particular issue is also added.

2021-08-28  Facundo Tuesca  <facu@tuesca.com>

	Add field to keep track of last written directory.
	This adds a new `tif_lastdiroff` field to the TIFF data structure
	and uses it to store the offset of the last written directory.

	Appending a new directory required traversing the whole file
	to find the last directory. By keeping track of its offset in this
	new field, the search is no longer necessary.

	Since this offset is only stored in-memory, the first directory
	append after opening a file will have to transverse the whole
	directory list. Subsequent calls will have access to the last
	offset, avoiding the transversal.

2021-06-10  Even Rouault  <even.rouault@spatialys.com>

	tif_jpeg.c: workaround bug of libjpeg 9d that defers Huffman table creation
	Fixes #266

	libjpeg-9d no longer creates default Huffman tables in
	jpeg_set_defaults(), which make their emission in the JpegTables tag no
	longer possible. Workaround that by borrowing code from libjpeg to
	manually create them when they are not initialized.

	tif_jpeg.c: do not emit progressive scans with mozjpeg.
	Relates to #266

	- On writing, explicitly disable progressive scans, which is normally
	  not enabled, except with mozjpeg.
	- On reading, emit a warning when encountering progressive scans.

2020-10-16  Even Rouault  <even.rouault@spatialys.com>

	Add support for optional building against libdeflate for faster Zip/Deflate compression/decompression.
	So we can have 2 kind of builds with the Zip/Deflate codec:
	- zlib only
	- zlib + libdeflate

	Speed improvements in the 35%-50% range can be expected when libdeflate is used.
	Compression level up to 12 is now supported (capped to 9 when zlib is used).
	Still requires zlib for situations where libdeflate cannot be used (that
	is for scanline access, since libdeflate has no streaming mode)

	Pseudo-tag TIFFTAG_DEFLATE_SUBCODEC=DEFLATE_SUBCODEC_ZLIB/DEFLATE_SUBCODEC_LIBDEFLATE
	is added to control which subcodec (zlib or libdeflate) should be used (it defaults
	of course to libdeflate, when it is available).
	This is mostly aimed at being used on the writing side, to be able to reproduce
	output of previous libtiff versions at a binary level, in situations where this would
	be really needed. Or as a safety belt in case there would be unforeseen issues
	with using libdeflate.
	It can be used to know when libdeflate is available at runtime (DEFLATE_SUBCODEC_LIBDEFLATE
	will be the default value in that situation).

	Of course, deflate codestreams produced by libdeflate can be read by zlib, and vice-versa.

	3440ac216463fcad170bbb391491e69730a59ffa.

	As SETVALUE() now returns an error, this allow the decoder to exit.

	Otherwise, the assert(x == lastx) in _TIFFFax3fillruns() can trigger.

	Make the default whitepoint and ycbcrcoeffs arrays const.

2020-03-07  Adam Goode  <adam@spicenitz.org>

	Make pointers returned via TIFFGetField const.
	According to http://bugzilla.maptools.org/show_bug.cgi?id=2125#c6
	callers are not allowed to modify pointer or array values returned from
	TIFFGetField or the like. So, make this explicit in the documentation
	by specifying these things as const. Note that this is not an ABI
	change, since C does not encode const in libraries. Also, this is

	Rational with Double Precision Upgrade

	See merge request libtiff/libtiff!100

2020-02-27  Su_Laus  <sulau@freenet.de>

	Rational with Double Precision Upgrade.
	Unfortunately, custom rational tags (TIFF_RATIONAL with field_bit=FIELD_CUSTOM) are defined as TIFF_SETGET_DOUBLE
	but for the reading interface and LibTiff internally they are stored ALWAYS as floating point SINGLE precision.
	Double precision custom rational tags are not supported by LibTiff.

	For the GPS tags in WGS84 a higher accuracy / precision is needed.
	Therefore, this upgrade is made, keeping the old interface for the already defined tags and allowing a double precision definition,
	as well as calculating rationals with higher accuracy / precision.
	This higher accuracy can be used for newly defined tags like that in EXIF/GPS.

	Refer also to the very old Bugzilla issue 2542 (#69)

	A test file rational_precision2double.c is added, which shows prevention of the old interface to the already defined custom rational tags
	with the standard library as well as with the upgraded library.

	Also TIFFTAG_XRESOLUTION, TIFFTAG_YRESOLUTION, TIFFTAG_XPOSITION, TIFFTAG_YPOSITION amended from TIFF_SETGET_DOUBLE to TIFF_SETGET_FLOAT and testcase inserted in rational_precision2double.c

	Simplify nmake configuration for building port directory.  Now there is only one boolean setting to enable building strtoll() and strtoull() port functions.  The boolean setting enables the necessary port files to be built, but the remainder of the logic is via pre-processor code in the common tif_config.h, which was prepared before entering the port directory to do a build.

2020-01-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	Make sure that tif_config.h is produced prior to entering the port directory and add an include path so that the port files can include tif_config.h.  Do not actually include tif_config.h at this time since CMake and Autotools builds are not prepared for that.  This issue could be handled by updating the CMake and Autotools builds or by adding a define which directs libport.h to include tif_config.h.

2020-01-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	nmake.opt:

	  Provide defaults suitable for MSVC prior to 14.0.

	libport.h:

	  The sense of the pre-processor logic was inverted from what it
	  should be.  The intention is to only provide the prototype if the
	  function is missing.

2020-01-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2019-08-13  Even Rouault  <even.rouault@spatialys.com>

	Fix integer overflow in _TIFFCheckMalloc() and other implementation-defined behaviour (CVE-2019-14973)
	_TIFFCheckMalloc()/_TIFFCheckRealloc() used a unsafe way to detect overflow
	in the multiplication of nmemb and elem_size (which are of type tmsize_t, thus
	signed), which was especially easily triggered on 32-bit builds (with recent
	enough compilers that assume that signed multiplication cannot overflow, since
	this is undefined behaviour by the C standard). The original issue which lead to
	this fix was triggered from tif_fax3.c

	There were also unsafe (implementation defied), and broken in practice on 64bit
	builds, ways of checking that a uint64 fits of a (signed) tmsize_t by doing
	(uint64)(tmsize_t)uint64_var != uint64_var comparisons. Those have no known
	at that time exploits, but are better to fix in a more bullet-proof way.
	Or similarly use of (int64)uint64_var <= 0.

2019-08-04  Su Laus  <sulau@freenet.de>

	Reading of Tiff tags with ID = 0 (like GPSVERSIONID) corrected.
	  IGNORE placeholder in tif_dirread.c is now replaced by a field dir_ignore in the TIFFDirEntry structure

	  Currently, in tif_dirread.c a special IGNORE value for the tif tags is defined
	  in order to flag status preventing already processed tags from further processing.
	  This irrational behaviour prevents reading of custom tags with id code 0 - like tag GPSVERSIONID from EXIF 2.31 definition.

	  An additional field 'tdir_ignore' is now added to the TIFFDirEntry structure and code is changed
	  to allow tags with id code 0 to be read correctly.

	  This change was already proposed as pending improvement in tif_dirread.c around line 32.

	Those advanced writing functions must be used in a particular sequence
	to make their intended effect. Their aim is to control when/where

	The purpose of this is to generate 'cloud-optimized geotiff' files where
	the first KB of the file only contain the IFD entries without the potentially
	large strile arrays. Those are written afterwards.

	The typical sequence of calls is:
	TIFFOpen()
	[ TIFFCreateDirectory(tif) ]
	Set fields with calls to TIFFSetField(tif, ...)
	TIFFDeferStrileArrayWriting(tif)
	TIFFWriteCheck(tif, ...)
	 TIFFWriteDirectory(tif)
	 ... potentially create other directories and come back to the above directory
	TIFFForceStrileArrayWriting(tif): emit the arrays at the end of file

	See test/defer_strile_writing.c for a practical example.

2019-05-10  Even Rouault  <even.rouault@spatialys.com>

	Make defer strile offset/bytecount loading available at runtime.
	... and add per-strile offset/bytecount loading capabilities.

	Part of this commit makes the behaviour that was previously met when
	libtiff was compiled with -DDEFER_STRILE_LOAD available for default builds
	when specifying the new 'D' (Deferred) TIFFOpen() flag. In that mode, the [Tile/Strip][ByteCounts/Offsets]
	arrays are only loaded when first accessed. This can speed-up the opening
	of files stored on the network when just metadata retrieval is needed.
	This mode has been used for years by the GDAL library when compiled with
	its embedded libtiff copy.

	To avoid potential out-of-tree code (typically codecs) that would use
	the td_stripbytecount and td_stripoffset array inconditionnaly assuming they
	have been loaded, those have been suffixed with _p (for protected). The
	use of the new functions mentioned below is then recommended.

	Another addition of this commit is the capability of loading only the
	values of the offset/bytecount of the strile of interest instead of the
	whole array. This is enabled with the new 'O' (Ondemand) flag of TIFFOpen()
	(which implies 'D'). That behaviour has also been used by GDAL, which hacked
	into the td_stripoffset/td_stripbytecount arrays directly. The new code
	added in the _TIFFFetchStrileValue() and _TIFFPartialReadStripArray() internal
	functions is mostly a port of what was in GDAL GTiff driver previously.

	Related to that, the public TIFFGetStrileOffset[WithErr]() and TIFFGetStrileByteCount[WithErr]()
	functions have been added to API. They are of particular interest when
	using sparse files (with offset == bytecount == 0) and you want to detect
	if a strile is present or not without decompressing the data, or updating
	an existing sparse file.
	They will also be used to enable a future enhancement where client code can entirely
	skip bytecount loading in some situations

	A new test/defer_strile_loading.c test has been added to test the above
	capabilities.

2019-05-10  Even Rouault  <even.rouault@spatialys.com>

	Creation: use SHORT type when possible for StripByteCounts/TileByteCounts
	This follows the same logic as previous commit.

2019-05-09  Even Rouault  <even.rouault@spatialys.com>

	BigTIFF creation: write TileByteCounts/StripByteCounts tag with LONG when possible
	In most situations of BigTIFF file, the tile/strip sizes are of reasonable size,
	that is they fit on a 4-byte LONG. So in that case, use LONG instead of LONG8
	to save some space. For uncompressed file, it is easy to detect such situations
	by checking at the TIFFTileSize64()/TIFFStripSize64() return. For compressed file,
	we must take into account the fact that compression may sometimes result in
	larger compressed data. So we allow this optimization only for a few select
	compression times, and take a huge security margin (10x factor). We also only
	apply this optimization on multi-strip files, so as to allow easy on-the-fly
	growing of single-strip files whose strip size could grow above the 4GB threshold.

	This change is compatible with the BigTIFF specification. According to
	https://www.awaresystems.be/imaging/tiff/bigtiff.html:
	"The StripOffsets, StripByteCounts, TileOffsets, and TileByteCounts tags are
	allowed to have the datatype TIFF_LONG8 in BigTIFF. Old datatypes TIFF_LONG,
	and TIFF_SHORT where allowed in the TIFF 6.0 specification, are still valid in BigTIFF, too. "
	On a practical point of view, this is also compatible on reading/writing of
	older libtiff 4.X versions.

	The only glitch I found, which is rather minor, is when using such a BigTIFF
	file with TileByteCounts/StripByteCounts written with TIFF_LONG, and updating
	it with an older libtiff 4.X version with a change in the
	[Tile/Strip][ByteCounts/Offsets] array. In that case the _TIFFRewriteField()
	function will rewrite the directory and array with TIFF_LONG8, instead of updating
	the existing array (this is an issue fixed by this commit). The file will
	still be valid however, hence the minor severity of this.

	tif_dir: unset transferfunction field if necessary.
	The number of entries in the transfer table is determined as following:

	(td->td_samplesperpixel - td->td_extrasamples) > 1 ? 3 : 1

	This means that whenever td->td_samplesperpixel or td->td_extrasamples are
	modified we also need to make sure that the number of required entries in
	the transfer table didn't change.

	If it changed and the number of entries is higher than before we should
	invalidate the transfer table field and free previously allocated values.
	In the other case there's nothing to do, additional tf entries won't harm
	and properly written code will just ignore them since spp - es < 1.

	For instance this situation might happen when reading an OJPEG compressed
	image with missing SamplesPerPixel tag. In this case the SamplesPerPixel
	field might be updated after setting the transfer table.

	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.

	When libtiff is included in a super project via a simple
	`add_subdirectory(libtiff)`, this way the `tiff` library target has all

	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.

	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 uninitialized 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.

	* .appveyor.yml, .travis.yml, build/travis-ci: apply patches
	0001-ci-Travis-script-improvements.patch and
	0002-ci-Invoke-helper-script-via-shell.patch by Roger Leigh
	(sent to mailing list)

2017-06-08  Even Rouault <even.rouault at spatialys.com>

	* .travis.yml, build/travis-ci: new files from
	0001-ci-Add-Travis-support-for-Linux-builds-with-Autoconf.patch by
	Roger Leigh (sent to mailing list on 2017-06-08)
	This patch adds support for the Travis-CI service.

	* .appveyor.yml: new file from
	0002-ci-Add-AppVeyor-support.patch by Roger Leigh (sent to mailing
	list on 2017-06-08)
	This patch adds a .appveyor.yml file to the top-level.  This allows
	one to opt in to having a branch built on Windows with Cygwin,
	MinGW and MSVC automatically when a branch is pushed to GitHub,
	GitLab, BitBucket or any other supported git hosting service.

	* CMakeLists.txt, test/CMakeLists.txt, test/TiffTestCommon.cmake: apply
	patch 0001-cmake-Improve-Cygwin-and-MingGW-test-support.patch from Roger
	Leigh (sent to mailing list on 2017-06-08)
	This patch makes the CMake build system support running the tests
	with MinGW or Cygwin.

	* libtiff/tif_swab.c: if DISABLE_CHECK_TIFFSWABMACROS is defined, do not do
	the #ifdef TIFFSwabXXX checks. Make it easier for GDAL to rename the symbols
	of its internal libtiff copy.

2017-06-01  Even Rouault <even.rouault at spatialys.com>

	* libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
	and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
	codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
	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.
	Patch derived from 0063-Handle-properly-CODEC-specific-tags.patch
	(http://bugzilla.maptools.org/show_bug.cgi?id=2580) by Raphaël Hertzog.

	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  <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).

	* 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  <bfriesen@simple.dallas.tx.us>

	* configure.ac: libtiff 4.0.5 released.

2015-08-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* 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  <bfriesen@simple.dallas.tx.us>

	* 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  <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.

	* 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  <bfriesen@simple.dallas.tx.us>

	* 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  <bfriesen@simple.dallas.tx.us>

	* 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  <bfriesen@simple.dallas.tx.us>

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

2015-08-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* CMakeLists.txt: Applied patch by Roger Leigh to fix libtiffxx
	symbol versioning.  Patch was mailed to libtiff list on Thu, 13
	Aug 2015.

2015-06-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* CMakeLists.txt: Add CMake patchset by Roger Leigh as posted to
	libtiff mailing list on Mon, 22 Jun 2015 21:21:01 +0100. Several
	corrections to ensure that the autotools build still works were
	added by me.  I have not yet tested the build using 'cmake' or
	MSVC with 'nmake'.

2015-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* test/Makefile.am: tiff2rgba-quad-tile.jpg.sh depends on the JPEG
	library so only execute if JPEG is available.

	* libtiff 4.0.4 released.

	* 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
	only include it when JPEG support is available.

	* html/build.html: Try to improve the nmake-based VC++ build
	description.

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

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

	* libtiff/libtiff.def: TIFFRasterScanline does not exist so remove
	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 interpreted 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.

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

2011-03-10  Frank Warmerdam  <warmerdam@pobox.com>

	* 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.

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

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.

	http://bugzilla.maptools.org/show_bug.cgi?id=2293

2011-01-24  Olivier Paquet  <olivier.paquet@gmail.com>

	* 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.
	http://www.asmail.be/msg0055458208.html

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.

	http://trac.osgeo.org/gdal/ticket/3894

2011-01-03  Lee Howard <faxguy@howardsilvan.com>

	* libtiff/tif_jpeg.c: Fix regressions with 2 and 3 band images

	* tools/tiffcp.c, man/tiffcp.1: Added support for specifying the
	compression level parameter (preset) for Deflate and LZMA encoders,
	e.g "-c lzma:p1" or "-c zip:p9".

	* libtiff/tif_lzma.c: Properly set the LZMA2 compression level
	(preset) in LZMAVSetField().

2010-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/Makefile.am (libtiff_la_SOURCES): Added tif_lzma.c to
	Makefile.

	Document Creator, and Page Orientation

2010-07-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* 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  <dron@ak4719.spb.edu>

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

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>

	* 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  <dron@ak4719.spb.edu>

	* libtiff/tif_getimage.c: Avoid wrong math du to the signed/unsigned

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

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

2010-05-06  Andrey Kiselev  <dron@ak4719.spb.edu>

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

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

	* 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=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>

	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,

	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

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.

	* tools/tiffcp.c: Simplify inknames code to avoid pointless test.
	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

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1577

2007-07-13  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff 4.0.0alpha released.

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

	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

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1566

	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 definitions 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
	functionality from Richard Nolde. As per bug

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1525

2007-03-28  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_fax3.c: "inline static" -> "static inline" for IRIC CC.

2007-03-17  Joris Van Damme  <joris.at.lebbeke@skynet.be>

	* start of BigTIFF upgrade - CVS HEAD unstable until further notice

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

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

	* libtiff/tif_win32.c: made inclusion of windows.h unconditional

	* libtiff/tif_win32.c: replaced preprocessor indication for consiously
	unused arguments by standard C indication for the same

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

	* libtiff/tif_dirread.c: Use uint32 type instead of tsize_t in byte

	it was set as infinite. As per bug

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1368

	* tools/tiffcrop.c, man/tiffcrop.1: New tiffcrop utility contributed
	by Richard Nolde. As per bug

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1383

2007-02-22  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/tif_dir.c: Workaround for incorrect TIFFs with
	ExtraSamples == 999 produced by Corel Draw. As per bug

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1490

	* libtiff/{tif_dirread.c, tif_read.c}: Type of the byte counters
	changed from tsize_t to uint32 to be able to work with data arrays
	larger than 2GB. Fixes bug

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

	Idea submitted by Matt Hancher.

2007-01-31  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tif2rgba.c: This utility does not work properly on big-endian
	architectures. It was fixed including the bug

	http://bugzilla.remotesensing.org/show_bug.cgi?id=1149

2007-01-15  Mateusz Loskot <mateusz@loskot.net>

	* Submitted libtiff port for Windows CE platform
	* libtiff/tif_config.wince.h: Added configuration header for WinCE.

	* libtiff/tif_wince.c: Added WinCE-specific implementation of some
	functions from tif_win32.c.
	* libtiff/tif_win32.c: Disabled some functions already reimplemented in tif_wince.c.
	* libtiff/tiffiop.h, port/lfind.c: Added conditional include of some
	standard header files for Windows CE build.
	* tools/tiffinfoce.c: Ported tiffinfo utility for Windows CE.

2006-11-19  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_write.c: TIFFAppendToStrip() - clear sorted flag if
	we move a strip.
	http://bugzilla.remotesensing.org/show_bug.cgi?id=1359

2006-10-13  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/contrib/dbs/xtiff/xtiff.c: Make xtiff utility compilable.
	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

	* 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.

	now also uses TIFFRGBAImageOK before reading. This is additional fix
	for http://bugzilla.remotesensing.org/show_bug.cgi?id=110

2002-03-25  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/: tif_getimage.c: Additional check for supported
	codecs added in TIFFRGBAImageOK and TIFFReadRGBAImage now uses
	TIFFRGBAImageOK before reading.
	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 unknown sizes founded.
	Closes http://bugzilla.remotesensing.org/show_bug.cgi?id=109

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

	* libtiff/tif_getimage.c: Added support for correct handling
	`Orientation' tag in gtTileContig. Should be added in other gt*

	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
	be stripped when installing, utility binaries will do.	Closes

	* configure: OpenBSD changes for Sparc64 and DSO version.

	http://bugzilla.remotesensing.org/show_bug.cgi?id=96

2002-02-05  Frank Warmerdam  <warmerdam@pobox.com>

	* config.site/configure: added support for OJPEG=yes option to enable
	OJPEG support from config.site.

2002-01-27  Frank Warmerdam  <warmerdam@pobox.com>

	* html/document.html: fixed links for TIFf 6 docs.

	* libtiff/tif_read.c: Fixed TIFFReadEncodedStrip() to fail if the
	decodestrip function returns anything not greater than zero as per
	http://bugzilla.remotesensing.org/show_bug.cgi?id=97

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

2002-01-16  Frank Warmerdam  <warmerdam@pobox.com>

	* tools/tiffdump.c: include TIFFTAG_JPEGTABLES in tag list.

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.

	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

2001-05-11  Frank Warmerdam  <warmerdam@pobox.com>

	* tiff.h: removed, it duplicates libtiff/tiff.h.

2001-05-08  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirinfo.c: moved pixar and copyright flags to
	ensure everything is in order.

	* libtiff/libtiff.def: added TIFFCreateDirectory and
	TIFFDefaultStripSize as per:

	  http://bugzilla.remotesensing.org/show_bug.cgi?id=46

2001-05-02  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
	several 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

	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 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>
