TIFFRGBAImage interface now properly supports allpossible orientations, i.e. images will be flipped both in horizontal andvertical directions if required. 'Known bugs' section now removed from theappropriate 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 functionTIFFIsCODECConfigured(), suggested by Ross Finlayson.<li> libtiff/tif_ojpeg.c: TIFFVGetField() function now can properly extractthe fields from the OJPEG files. Patch supplied by Ross Finlayson.<li> libtiff/tif_dir.h: _TIFFFindOrRegisterdInfo declaration replacedwith _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 (asit 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 spaceconversion code: CIE L*a*b* 1976 images now supported by the TIFFRGBAImageinterface. YCbCr to RGB conversion code also moved there and now has<a href="./man/TIFFcolor.3t.html">publicly available interface</a>. Theseroutines currently used in TIFFRGBAImage interface only and not supported inother libtiff tools yet. So if you want, for example, to convert CIE Lab imageinto PostScript file you should do it in two steps: chnge colorspace to RGBusing <a href="./man/tiff2rgba.1.html">tiff2rgba</a> utility abd then processit with the <a href="./man/tiff2ps.1.html">tiff2ps</a>.<li> libtiff/tif_tile.c: Remove spurious use of "s" (sample) in theplanarconfig_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() functionas suggested by Chris Hanson.<li> libtiff/{tif_lzw.c, tif_fax3.c}: Proper support for update modeas per bug 424.</UL><P><HR WIDTH=65% ALIGN=left><!--------------------------------------------------------------------------><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 byRoss Finlayson, to directly convert TIFF files to PDF.<li> <a href=./man/tiffgt.1.html>tiffgt</a>: Unmaintained and platformdependent sgigt utility removed and replaced with the completely rewrittenportable <a href=./man/tiffgt.1.html>tiffgt</a> tool (depend on OpenGL andGLUT).
