<A NAME="highlights"><B><FONT SIZE=+3>M</FONT>AJOR CHANGES:</B></A> | |
<ul> | |
<li> New utility <a href="./man/tiff2pdf.1.html">tiff2pdf</a> | |
for converting TIFF images directly into PDF. | |
<li> New <a href="./man/TIFFcolor.3t.html">color conversion module</a>. | |
<li> Full support for Orientation tag in | |
<a href="./man/TIFFReadRGBAImage.3t.html">TIFFRGBAImage</a> interface. | |
<li> Many bugs fixed. | |
</ul> | |

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> | |
<UL> | |
<li> libtiff/makefile.vc, tools/makefile.vc: Support for IJG JPEG library. | |
<li> Makefile.in: Add an absolute path to the test_pics.sh call. | |
<li> Makefile.in: Add an absolute path to the test_pics.sh call. | |
<li> libtiff/tiffcomp.h: #define _BSDTYPES_DEFINED when defining BSD typedefs. | |
<li> configure, libtiff/{Makefile.in, mkversion.c}: Relative buildings fixed. | |
<li> Makefile.in: Add an absolute path to the test_pics.sh call. | |

<!---------------------------------------------------------------------------> | |
<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> | |
<UL> | |
<li> 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. | |
<li> libtiff/{tif_getimage.c, tif_aux.c}: Read WhitePoint tag from the | |
file and properly use it for CIE Lab 1976 to RGB transform. | |
<li> 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. | |
<li> libtiff/tif_luv.c: Fixed bug in 48-bit to 24-bit conversion routine, | |
reported by Antonio Scuri. | |
<li> libtiff/{tiffio.h, tif_codec.c}: Added new function | |
TIFFIsCODECConfigured(), suggested by Ross Finlayson. | |
<li> libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extract | |
the fields from the OJPEG files. Patch supplied by Ross Finlayson. | |
<li> libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replaced | |
with _TIFFFindOrRegisterFieldInfo as reported by Ross Finlayson. | |
<li> libtiff/tif_dirinfo.c: Implemented binary search in _TIFFMergeFieldInfo(). | |
Patch supplied by Ross Finlayson. | |
<li> tif_dirread.c: do not mark all anonymously defined tags to be IGNOREd (as | |
it was done in 3.6.0). | |
<li> libtiff/{tiff.h, tif_dirinfo.c}: Added support for IFD (13) datatype, | |
intruduced in "Adobe PageMaker TIFF Technical Notes". | |
<li> 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 | |
<a href="./man/TIFFcolor.3t.html">publicly available interface</a>. 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 <a href="./man/tiff2rgba.1.html">tiff2rgba</a> utility abd then process | |
it with the <a href="./man/tiff2ps.1.html">tiff2ps</a>. | |
<li> libtiff/tif_tile.c: Remove spurious use of "s" (sample) in the | |
planarconfig_contig case in TIFFComputeTile() as per bug 387 | |
<li> libtiff/tiffiop.h: New macros: TIFFmax and TIFFmin. | |
<li> libtiff/{tiffio.h, tif_strip.c}: Added TIFFRawStripSize() function | |
as suggested by Chris Hanson. | |
<li> libtiff/{tif_lzw.c, tif_fax3.c}: Proper support for update mode | |
as per bug 424. | |

<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A> | |
<UL> | |
<li> <a href=./man/tiff2pdf.1.html>tiff2pdf</a>: New tool, written by | |
Ross Finlayson, to directly convert TIFF files to PDF. | |
<li> <a href=./man/tiffgt.1.html>tiffgt</a>: Unmaintained and platform | |
dependent sgigt utility removed and replaced with the completely rewritten | |
portable <a href=./man/tiffgt.1.html>tiffgt</a> tool (depend on OpenGL and | |
GLUT). This tool will not build by default. | |
<li> <a href=./man/ras2tiff.1.html>ras2tiff</a>: Properly determine | |
SUN Rasterfiles with the reverse byte order (it is reported by the magic | |
header field). Problem reported by Andreas Wiesmann. | |
<li> <a href=./man/raw2tiff.1.html>raw2tiff</a>: Implemented image size | |
guessing using correlation coefficient calculation between two neighbour | |
lines. | |
