|
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. |

|
62 |
|
63 <UL> |
|
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. |
|
70 |
|
71 <li> libtiff/tiffcomp.h: #define _BSDTYPES_DEFINED when defining BSD typedefs. |
|
72 |
|
73 <li> configure, libtiff/{Makefile.in, mkversion.c}: Relative buildings fixed. |
|
74 |

83 <A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> |
|
84 |
|
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. |

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. |
