+
+
+
+MAJOR CHANGES:
+
+
+ - Significant changes in software configuration: we are switched
+ to GNU autotools now.
+
+
- tiffset: tiffset now can set any libtiff supported tags. Tags
+ can be supplied by the mnemonic name or number.
+
+
+
+
+
+
+CHANGES IN THE SOFTWARE CONFIGURATION:
+
+
+ - Get rid of the old configuration system and switch to
+ GNU autotools.
+
+
+
+
+
+
+CHANGES IN LIBTIFF:
+
+
+ - libtiff/tif_ojpeg.c: Fixed problem with duplicated SOI and SOF
+ markers as per bug
+ .
+
+
- libtiff/{tif_open.c, tiffio.h}: New function added:
+ TIFFIsBigEndian(). Function returns nonzero if given was file written
+ in big-endian order.
+
+
- libtiff/tif_print.c: added (untested) support for printing
+ SSHORT, SLONG and SRATIONAL fields.
+
+
- libtiff/tif_fax3.c: Avoid reading CCITT compression options
+ if compression type mismatches. See
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=565.
+
+
- libtiff/tif_strip.c: Never return 0 from the TIFFNumberOfStrips().
+
+
- libtiff/tif_dirread.c: Workaround for broken TIFF writers which
+ store single SampleFormat value for multisampled images. See
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=562.
+
+
- libtiff/tif_write.c: Allow in-place updating of the compressed
+ images (don't work properly with all codecs). For details see GDAL bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=534.
+
+
- libtiff/tif_jpeg.c: Workaround for wrong sampling factors used
+ in the Intergarph JPEG compressed TIFF images as per bug:
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=532.
+
+
- libtiff/tif_open.c: Use dummy mmap/munmap functions in
+ TIFFClientOpen() when the appropriate client functions was not
+ supplied by user.
+
+
- libtiff/tif_dirread.c: Fixed problem with handling TIFF_UNDEFINED
+ tag type in TIFFFetchNormalTag() as per bug
+ .
+
+
- libtiff/tif_codec.c: Fixed typo in TIFFInitPackBits name as per:
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=494.
+
+
- libtiff/tif_fax3.c: Fixed problem, introdiced in 3.6.1 release,
+ with the CCITT encoding modes as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=483.
+ We need more work on fax codec to support update mode.
+
+
- libtiff/tiff.h: Fixed tag definitions for TIFFTAG_YCLIPPATHUNITS
+ and TIFFTAG_INDEXED as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=475.
+
+
- libtiff/{tif_win32.c, tif_unix.c}: Check whether the pointer is
+ NULL before proceeding further as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=474.
+ Check results, returned by the TIFFFdOpen() before returning and close
+ file if TIFFFdOpen() failed as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=468.
+
+
- libtiff/{libtiff.def, tif_close.c, tiffio.h, tif_open.c}:
+ Separate TIFFCleanup() from the TIFFClose() in order to fix the bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=468.
+
+
- libtiff/tif_dirwrite.c: Fixed handling of writable ASCII tags
+ that are field_passcount=TRUE properly. Arguably anonymous custom
+ tags should be declared as passcount=FALSE, but I don't want to change
+ that without a careful review.
+
+
- libtiff/tif_write.c: Fixed reporting size of the buffer in case
+ of stripped image in TIFFWriteBufferSetup(). As per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=460.
+
+
- libtiff/tif_dir.c: Incomplete cleanup in TIFFFreeDirectory(),
+ patch from Gerben Koopmans.
+
+
- libtiff/tif_dirread.c: Check field_passcount value before setting
+ the value of undefined type, patch from Gerben Koopmans.
+
+
- libtiff/{tiff.h, tif_fax3.c}:Fixes for AMD 64 platform as
+ suggested by Jeremy C. Reed.
+
+
- libtiff/tif_win32.c: Fixed problem with _TIFFrealloc() when
+ the NULL pointer passed. Patch supplied by Larry Grill.
