+
+MAJOR CHANGES:
+
+
+
+
+
+
+
+CHANGES IN THE SOFTWARE CONFIGURATION:
+
+
+
+- libtiff/makefile.vc, tools/makefile.vc: Support for IJG JPEG library.
+
+
- Makefile.in: Add an absolute path to the test_pics.sh call.
+
+
- Makefile.in: Add an absolute path to the test_pics.sh call.
+
+
- libtiff/tiffcomp.h: #define _BSDTYPES_DEFINED when defining BSD typedefs.
+
+
- configure, libtiff/{Makefile.in, mkversion.c}: Relative buildings fixed.
+
+
- Makefile.in: Add an absolute path to the test_pics.sh call.
+
+
+
+
+
+
+
+CHANGES IN LIBTIFF:
+
+
+
+- libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: Added support
+for ReferenceBlackWhite tag handling when converted from YCbCr color space as
+per bug 120.
+
+
- libtiff/{tif_getimage.c, tif_aux.c}: Read WhitePoint tag from the
+file and properly use it for CIE Lab 1976 to RGB transform.
+
+
- libtiff/{tif_getimage.c, tiffio.h}: Finally resolved problems with
+orientation handling. TIFFRGBAImage interface now properly supports all
+possible orientations, i.e. images will be flipped both in horizontal and
+vertical directions if required. 'Known bugs' section now removed from the
+appropriate manual pages.
+
+
- libtiff/tif_luv.c: Fixed bug in 48-bit to 24-bit conversion routine,
+reported by Antonio Scuri.
+
+
- libtiff/{tiffio.h, tif_codec.c}: Added new function
+TIFFIsCODECConfigured(), suggested by Ross Finlayson.
+
+
- libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extract
+the fields from the OJPEG files. Patch supplied by Ross Finlayson.
+
+
- libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replaced
+with _TIFFFindOrRegisterFieldInfo as reported by Ross Finlayson.
+
+
- libtiff/tif_dirinfo.c: Implemented binary search in _TIFFMergeFieldInfo().
+Patch supplied by Ross Finlayson.
+
+
- tif_dirread.c: do not mark all anonymously defined tags to be IGNOREd (as
+it was done in 3.6.0).
+
+
- libtiff/{tiff.h, tif_dirinfo.c}: Added support for IFD (13) datatype,
+intruduced in "Adobe PageMaker TIFF Technical Notes".
+
+
- libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: New color space
+conversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImage
+interface. YCbCr to RGB conversion code also moved there and now has
+publicly available interface. These
+routines currently used in TIFFRGBAImage interface only and not supported in
+other libtiff tools yet. So if you want, for example, to convert CIE Lab image
+into PostScript file you should do it in two steps: chnge colorspace to RGB
+using tiff2rgba utility abd then process
+it with the tiff2ps.
+
+
- libtiff/tif_tile.c: Remove spurious use of "s" (sample) in the
+planarconfig_contig case in TIFFComputeTile() as per bug 387
+
+
- libtiff/tiffiop.h: New macros: TIFFmax, TIFFmin and TIFFrint.
+
+
- libtiff/{tiffio.h, tif_strip.c}: Added TIFFRawStripSize() function
+as suggested by Chris Hanson.
+
+
- libtiff/{tif_lzw.c, tif_fax3.c}: Proper support for update mode
+as per bug 424.
+
+
+
+
+
+
+
+CHANGES IN THE TOOLS:
+
+
+
+- tiff2pdf: New tool, written by
+Ross Finlayson, to directly convert TIFF files to PDF.
+
+
- tiffgt: Unmaintained and platform
+dependent sgigt utility removed and replaced with the completely rewritten
+portable tiffgt tool (depend on OpenGL and
+GLUT). This tool will not build by default.
+
+
- ras2tiff: Properly determine
+SUN Rasterfiles with the reverse byte order (it is reported by the magic
+header field). Problem reported by Andreas Wiesmann.
+
+
- raw2tiff: Implemented image size
+guessing using correlation coefficient calculation between two neighbour
+lines.
+
+
+
+
+
+
+
+CHANGES IN THE CONTRIB AREA:
+
+
+- contrib/pds/{tif_pdsdirread.c, tif_pdsdirwrite.c}: Use TIFFDataWidth()
+function insted of tiffDataWidth array.
+
+
+
+
+
+CHANGES IN THE LZW COMPRESSION
+KIT:
+
+
+- Proper support for update mode as per bug 424.
