49 <li> New utility <a href="./man/tiff2pdf.1.html">tiff2pdf</a>
50 for converting TIFF images directly into PDF.
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.

61<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
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
75<li> Makefile.in: Add an absolute path to the test_pics.sh call.

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

151
152<li> <a href=./man/tiff2pdf.1.html>tiff2pdf</a>: New tool, written by
153Ross Finlayson, to directly convert TIFF files to PDF.
154
155<li> <a href=./man/tiffgt.1.html>tiffgt</a>: Unmaintained and platform
156dependent sgigt utility removed and replaced with the completely rewritten
157portable <a href=./man/tiffgt.1.html>tiffgt</a> tool (depend on OpenGL and
158GLUT). This tool will not build by default.
159
160<li> <a href=./man/ras2tiff.1.html>ras2tiff</a>: Properly determine
161SUN Rasterfiles with the reverse byte order (it is reported by the magic
162header field). Problem reported by Andreas Wiesmann.
163
164<li> <a href=./man/raw2tiff.1.html>raw2tiff</a>: Implemented image size
165guessing using correlation coefficient calculation between two neighbour
166lines.
