-<A NAME="highlights"><B><FONT SIZE=+3>M</FONT>AJOR CHANGES:</B></A>
-
-<UL>
- <li> New <b>tiffcrop</b> utility contributed by Richard Nolde.
- <b>tiffcrop</b> does the same as <b>tiffcp</b>, but also can crop,
- extract, rotate and mirror images.
-
- <li> tif_jbig.c: Added support for JBIG compression scheme
- (34661 code), contributed by Lee Howard.
-
- <li> Totally new implementation of OJPEG module from
- Joris Van Damme. No need to patch libjpeg anymore. Many OJPEG files
- should be supported now that was not supported previously.
-
-</UL>
-

-<!--------------------------------------------------------------------------->
-
-<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
-
-<UL>
-
- <li> tif_config.wince.h, tiffconf.wince.h, tif_wince.c: WinCE-specific
- compatibility stuff from Mateusz Loskot.
-
- <li> Rename config.h.vc and tif_config.h.vc to config.vc.h and
- tif_config.vc.h for easier identification by folks using an IDE.
-
- <li> configure, configure.ac: OJPEG support enabled by default (i.e.,
- whe the conformant JPEG support enabled).
-
- <li> README.vms, Makefile.am, configure.com, libtiff/{Makefile.am,
- tif_config.h-vms, tif_stream.cxx, tif_vms.c, tiffconf.h-vms}:
- Added support for OpenVMS by Alexey Chupahin.
-
- <li> nmake.opt: use /EHsc for VS2005 compatibility. Also define
- _CRT_SECURE_NO_DEPRECATE to avoid noise on VS2005.
-
-</UL>

-<!--------------------------------------------------------------------------->
-
-<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
-
-<UL>
- <li> tif_dirinfo.c (_TIFFFindFieldInfo): Don't attempt to
- bsearch() on a NULL fieldinfo list.
- (_TIFFFindFieldInfoByName): Don't attempt to lfind() on a NULL
- fieldinfo list.
-
- <li> 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.
-
- <li> tif_dirwrite.c: Fixed swapping of byte arrays stored
- in-place in tag offsets as per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1363">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1363</a>
-
- <li> 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
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1390">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1390</a> and
- <a href="http://www.asmail.be/msg0054766825.html">
- http://www.asmail.be/msg0054766825.html</a>
-
- <li> tif_dirread.c: Added special function to handle
- SubjectDistance EXIF tag as per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1362">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1362</a>
-
- <li> 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
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=890">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=89</a>
- Idea submitted by Matt Hancher.
-
- <li> tif_dir.c: Workaround for incorrect TIFFs with
- ExtraSamples == 999 produced by Corel Draw. As per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1490">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1490</a>
-
- <li> tif_write.c: TIFFAppendToStrip() - clear sorted flag if
- we move a strip.
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1359">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1359</a>
-
- <li> tif_fax3.c: Save the state of printdir codec dependent method.
-
- <li> tif_jpeg.c: Save the state of printdir codec dependent method
- as per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1273">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1273</a>
-
- <li> tif_win32.c: Fixed problem with offset value manipulation
- as per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1322">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1322</a>
-
- <li> tif_fax3.c, tif_next.c, tif_pixarlog.c: Fixed multiple
- vulnerabilities, as per Gentoo bug ():
- <a href="http://bugs.gentoo.org/show_bug.cgi?id=142383">
- http://bugs.gentoo.org/show_bug.cgi?id=142383</a>
-
- <li> tif_lzw.c, tif_zip.c: Fixed problems with mixing
- encoding and decoding on the same read-write TIFF handle. The LZW
- code can now maintain encode and decode state at the same time. The
- ZIP code will switch back and forth as needed.
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=757">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=757</a>
-
- <li> tif_msdos.c: Avoid handle leak for failed opens.
- c/o Thierry Pierron
-
- <li> tif_dirwrite.c: take care not to flush out buffer of strip/tile
- data in _TIFFWriteDirectory if TIFF_BEENWRITING not set. Relates
- to bug report by Peng Gao with black strip at bottom of images.
-
- <li> tif_dirwrite.c: make sure to use uint32 for wordcount in
- TIFFWriteNormanTag if writecount is VARIABLE2 for ASCII fields.
- It already seems to have been done for other field types. Needed
- for "tiffset" on files with geotiff ascii text.
-
- <li> tif_dirinfo.c: Added missed EXIF tag ColorSpace (40961).
-
- <li> tif_dirread.c: Move IFD fetching code in the separate
- function TIFFFetchDirectory() avoiding code duplication in
- TIFFReadDirectory() and TIFFReadCustomDirectory().
-
- <li>tif_readdir.c: Added case in EstimateStripByteCounts() for tiled
- files. Modified TIFFReadDirectory() to not invoke
- EstimateStripByteCounts() for case where entry 0 and 1 are unequal but
- one of them is zero.
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1204">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1204</a>
-
- <li> tif_open.c, tif_dirread.c, tiffiop.h: Move IFD looping
- checking code in the separate function TIFFCheckDirOffset().
-
- <li> tif_aux.c: Added _TIFFCheckRealloc() function.
-
- <li> tif_fax3.c: Fixed problems in fax decoder as per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=1194">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1194</a>
-
- <li> tif_jbig.c: Added support for JBIG compression scheme
- (34661 code) contributed by Lee Howard. As per bug
- <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=896">
- http://bugzilla.remotesensing.org/show_bug.cgi?id=896</a>
-
- <li> tif_getimage.c: Added support for planarconfig separate
- non-subsampled YCbCr (i.e. separate YCbCr with subsampling [1,1]).
-
- <li> tif_getimage.c: Revision of all RGB(A) put routines:
- <ul>
- <li> Conversion of unassociated alpha to associated alpha
- now done with more performant LUT, and calculation more
- correct.
- <li> Conversion of 16bit data to 8bit data now done with
- more performant LUT, and calculation more correct
- <li> Bugfix of handling of 16bit RGB with unassociated alpha
- </ul>
-
- <li> tif_ojpeg.c: totally new implementation
-
- <li> tif_getimage.c: removed TIFFTAG_JPEGCOLORMODE handling
- of OJPEG images in favor of tif_getimage.c native handling of
- YCbCr and desubsampling.
-
- <li> tif_jpeg.c: JPEGVSetField() so that altering the photometric
- interpretation causes the "upsampled" flag to be recomputed. Fixes
- peculiar bug where photometric flag had to be set before jpegcolormode
- flag.
