  47
  48 <ul>
  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.

  82
  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.

 150 <UL>
 151
 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.
