|
---|
51 | <li> New <a href="./man/TIFFcolor.3t.html">color conversion module</a>.
|
---|
52 | <li> Full support for Orientation tag in
|
---|
53 | <a href="./man/TIFFReadRGBAImage.3t.html">TIFFRGBAImage</a> interface.
|

54 | <li> Many bugs fixed.

64 |
|
---|
65 | <li> libtiff/makefile.vc, tools/makefile.vc: Support for IJG JPEG library.
|
---|
66 |
|
---|
67 | <li> Makefile.in: Add an absolute path to the test_pics.sh call.
|
---|
68 |
|

69 | <li> Makefile.in: Add an absolute path to the test_pics.sh call.

|
---|
85 | <UL>
|
---|
86 |
|
---|
87 | <li> libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: Added support
|
---|
88 | for ReferenceBlackWhite tag handling when converted from YCbCr color space as
|
---|
89 | per bug 120.
|
---|
90 |
|
---|
91 | <li> libtiff/{tif_getimage.c, tif_aux.c}: Read WhitePoint tag from the
|
---|
92 | file and properly use it for CIE Lab 1976 to RGB transform.
|
---|
93 |
|
---|
94 | <li> libtiff/{tif_getimage.c, tiffio.h}: Finally resolved problems with
|
---|
95 | orientation handling. TIFFRGBAImage interface now properly supports all
|
---|
96 | possible orientations, i.e. images will be flipped both in horizontal and
|
---|
97 | vertical directions if required. 'Known bugs' section now removed from the
|
---|
98 | appropriate manual pages.
|
---|
99 |
|
---|
100 | <li> libtiff/tif_luv.c: Fixed bug in 48-bit to 24-bit conversion routine,
|
---|
101 | reported by Antonio Scuri.
|
---|
102 |
|
---|
103 | <li> libtiff/{tiffio.h, tif_codec.c}: Added new function
|
---|
104 | TIFFIsCODECConfigured(), suggested by Ross Finlayson.
|
---|
105 |
|
---|
106 | <li> libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extract
|
---|
107 | the fields from the OJPEG files. Patch supplied by Ross Finlayson.
|
---|
108 |
|
---|
109 | <li> libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replaced
|
---|
110 | with _TIFFFindOrRegisterFieldInfo as reported by Ross Finlayson.
|
---|
111 |
|
---|
112 | <li> libtiff/tif_dirinfo.c: Implemented binary search in _TIFFMergeFieldInfo().
|
---|
113 | Patch supplied by Ross Finlayson.
|
---|
114 |
|
---|
115 | <li> tif_dirread.c: do not mark all anonymously defined tags to be IGNOREd (as
|
---|
116 | it was done in 3.6.0).
|
---|
117 |
|
---|
118 | <li> libtiff/{tiff.h, tif_dirinfo.c}: Added support for IFD (13) datatype,
|
---|
119 | intruduced in "Adobe PageMaker TIFF Technical Notes".
|
---|
120 |
|
---|
121 | <li> libtiff/{tif_color.c, tif_getimage.c, tiffio.h}: New color space
|
---|
122 | conversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImage
|
---|
123 | interface. YCbCr to RGB conversion code also moved there and now has
|
---|
124 | <a href="./man/TIFFcolor.3t.html">publicly available interface</a>. These
|
---|
125 | routines currently used in TIFFRGBAImage interface only and not supported in
|
---|
126 | other libtiff tools yet. So if you want, for example, to convert CIE Lab image
|
---|
127 | into PostScript file you should do it in two steps: chnge colorspace to RGB
|
---|
128 | using <a href="./man/tiff2rgba.1.html">tiff2rgba</a> utility abd then process
|
---|
129 | it with the <a href="./man/tiff2ps.1.html">tiff2ps</a>.
|
---|
130 |
|
---|
131 | <li> libtiff/tif_tile.c: Remove spurious use of "s" (sample) in the
|
---|
132 | planarconfig_contig case in TIFFComputeTile() as per bug 387
|
---|
133 |
|
---|
134 | <li> libtiff/tiffiop.h: New macros: TIFFmax and TIFFmin.
|
---|
135 |
|
---|
136 | <li> libtiff/{tiffio.h, tif_strip.c}: Added TIFFRawStripSize() function
|
---|
137 | as suggested by Chris Hanson.
|
---|
138 |
|
---|
139 | <li> libtiff/{tif_lzw.c, tif_fax3.c}: Proper support for update mode
|
---|
140 | as per bug 424.

152 | <li> <a href=./man/tiff2pdf.1.html>tiff2pdf</a>: New tool, written by
|

153 | Ross Finlayson, to directly convert TIFF files to PDF.
|
---|
154 |
|
---|
155 | <li> <a href=./man/tiffgt.1.html>tiffgt</a>: Unmaintained and platform
|

156 | dependent sgigt utility removed and replaced with the completely rewritten
|
---|
157 | portable <a href=./man/tiffgt.1.html>tiffgt</a> tool (depend on OpenGL and
|
---|
158 | GLUT). This tool will not build by default.
|
---|
159 |
|
---|
160 | <li> <a href=./man/ras2tiff.1.html>ras2tiff</a>: Properly determine
|
---|
161 | SUN Rasterfiles with the reverse byte order (it is reported by the magic
|
---|
162 | header field). Problem reported by Andreas Wiesmann.
|
---|
163 |
|
---|
164 | <li> <a href=./man/raw2tiff.1.html>raw2tiff</a>: Implemented image size
|

165 | guessing using correlation coefficient calculation between two neighbour
|
---|
166 | lines.
