+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:
+
+
+
+
+
+
+MAJOR CHANGES:
+
+
+ - Replace runtime endianess check with the compile time one.
+
+
- Added support for the new predictor type (floating point
+ predictor), defined at the TIFF Technical Note 3.
+
+
- Added Support for custom tags, passed by value.
+ Added support for all DNG tags.
+
+
+
+
+
+
+CHANGES IN THE SOFTWARE CONFIGURATION:
+
+
+
+
+
+
+
+CHANGES IN LIBTIFF:
+
+
+ - tiff.h: Use correct int size on Sparc 64bit/Sun compiler
+ platform. As per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=845
+
+
- tif_dirinfo.c, tif_print.c: TIFFFetchByteArray() returns
+ uint16 array when fetching the BYTE and SBYTE fields, so we should
+ consider result as pointer to uint16 array and not as array of chars.
+ As per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=831
+
+
- tif_dir.c: More efficient custom tags retrieval as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=830
+
+
- tif_win32.c: Use FILE_SHARE_READ | FILE_SHARE_WRITE share
+ mode in CreateFile() call as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=829
+
+
- tif_jpeg.c: Substantial fix for addtiffo problems with
+ JPEG encoded TIFF files. Pre-allocate lots of space for jpegtables
+ in directory.
+
+
- tif_dirread.c: Changed the code that computes
+ stripbytecount[0] if it appears bogus to ignore if stripoffset[0] is
+ zero. This is a common case with GDAL indicating a "null" tile/strip.
+
+
- tif_jpeg.c: added LIB_JPEG_MK1 support in JPEGDecodeRaw().
+
+
- tif_dirread.c: Ensure that broken files with too many
+ values in PerSampleShorts, TIFFFetchPerSampleLongs and
+ TIFFFetchPerSampleAnys work ok instead of crashing.
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=843
+
+
- tif_predict.h, tif_predict.c: Added ability to decode and encode
+ floating point predictor, as per TIFF Technical Note 3.
+ See http://chriscox.org/TIFF_TN3_Draft2.pdf for details.
+
+
- tiffio.h, tiffiop.h, tif_dir.c, tif_read.c, tif_swab.c:
+ Added _TIFFSwab24BitData() and TIFFSwabArrayOfLong() functions used to
+ swap 24-bit floating point values.
+
+
- tiff.h: Added predictor constants.
+
+
- tiffiop.h, tif_dir.c: Use uint32 type for appropriate values
+ in _TIFFVSetField() function. Inspired by the bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=816
+
+
- tif_open.c: Do not read header in case the output file should
+ be truncated (Ron).
+
+
- tif_dirinfo.c, tif_config.h.vc: Use lfind() instead of bsearch()
+ in _TIFFFindFieldInfoByName() function (Ron).
+
+
- tif_dir.c, tif_print.c: Properly handle all data types in custom
+ tags.
+
+
- dirinfo.c: Added DNG tags.
+
+
- tiff.h: Added missed DNG tag (LensInfo); added DNG 1.1.0.0 tags.
+
+
- tif_dir.c, tif_print.c: Added Support for custom tags, passed
+ by value.
+
+
- tiff.h, tif_dirinfo.c, tiffiop.h: Added EXIF related tags.
+
+
+
+
+
+
+CHANGES IN THE TOOLS:
+
+
+
+
+
+
+
+CHANGES IN THE CONTRIB AREA:
+
+
+
+ - addtiffo/{tif_overview.c, tif_ovrcache.c, tif_ovrcache.h}:
+ Make overviews working for contiguous images.
