+ − <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.+ −

Ross Finlayson, to directly convert TIFF files to PDF.+ −

dependent sgigt utility removed and replaced with the completely rewritten+ −

GLUT). This tool will not build by default.+ −

SUN Rasterfiles with the reverse byte order (it is reported by the magic+ −
header field). Problem reported by Andreas Wiesmann.+ −
