+TIFF CHANGE INFORMATION
+
+
+
+
+
+This document describes the changes made to the software between the
+previous and current versions (see above).
+If you don't find something listed here, then it was not done in this
+timeframe, or it was not considered important enough to be mentioned.
+The following information is located here:
+
+
+
+
+CHANGES IN THE SOFTWARE CONFIGURATION:
+
+
+
+ - Added GNULDdso target and switched linux and freebsd to use it.
+
- tools/Makefile.in: Modified to install properly on SGI.
+
- configure: Fixed DSO test for Linux as per patch from
+ Jan Van Buggenhout .
+
+
+
+
+
+CHANGES IN LIBTIFF:
+
+
+
+
+ - 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
+
+
- 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
+
+
- Applied patch for 0x0000 sequences in tif_fax3.h's definition
+ of EXPAND1D() as per bug 11 (from Roman).
+
+
- Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
+ cygwin compatibility.
+
+
- Applied patch from Roman Shpount to tif_fax3.c. This seems to
+ be a proper fix to the buffer sizing problem. See
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=11
+
+
- Fixed tif_getimage.c to fix overrun bug with YCbCr images without
+ downsampling. http://bugzilla.remotesensing.org/show_bug.cgi?id=10
+ Thanks to Nick Lamb for reporting the
+ bug and proving the patch.
+
+
- Fixed tif_jpeg.c so avoid destroying the decompressor before
+ we are done access data thanks to bug report from:
+ Michael Eckstein .
+
+
- tif_open.c: Don't set MMAP for O_RDWR files.
+
+
- tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
+ so that files opened for update can be strip chopped too.
+
+
- tif_read.c: fixed up bug with files missing rowsperstrip and
+ the strips per separation fix done a few weeks ago.
+
+
- Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
+ SAMPLEFORMAT_COMPLEXINT.
+
+
- index.html, bugs.html: added bugzilla info.
+
+
- tif_read.c: fix subtle bug with determining the number of
+ rows for strips that are the last strip in a separation but
+ not the last strip of all in TIFFReadEncodedStrip().
+
+
- Applied 16/32 bit fix to tif_fax3.c. Fix supplied by
+ Peter Skarpetis
+
+
- Modified tiffio.h logic with regard to including windows.h. It
+ won't include it when building with __CYGWIN__.
+
+
- README: update to mention www.libtiff.org, don't list Sam's old
+ email address.
+
+
- libtiff/tif_dirread.c: Don't use estimate strip byte count for
+ one tile/strip images with an offset, and byte count of zero. These
+ could be "unpopulated" images.
+
+
- tif_win32.c: Applied patch to fix overreads and ovverwrites
+ caught by BoundsChecker. From Arvan Pritchard
+ (untested).
+
+
- tif_getimage.c: Applied patch to silence VC6 warnings. From
+ Arvan Pritchard
+
+
- tif_lzw.c: Applied patch to silence VC6 warnings. From
+ Arvan Pritchard
+
+
- libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
+ Leonard Rosenthol . May interfere
+ with correct building on older systems. If so, please let me know.
+
+
+
+
+
+
+CHANGES IN THE TOOLS:
+
+
+
+ - tools/rgb2ycbcr.c: fixed output strip size to account for vertical
+ roundup if rows_per_strip not a multiple of vertical sample size.
+
+
- tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT.
+
+
- Modified tiff2bw to ensure portions add to 100%, and that
+ white is properly recovered. See bug
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=15 Patch
+ c/o Stanislav Brabec
+
+
+
+
+
+CHANGES IN CONTRIB:
+
