  86
  87 <UL>
  88         <li> tiffiop.h, tif_open.c: Added open option 'h' to avoid reading
  89         the first IFD when needed. As per bug
  90         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=875">
  91                 http://bugzilla.remotesensing.org/show_bug.cgi?id=875</a>
  92
  93         <li> tiff.h: Use correct int size on Sparc 64bit/Sun compiler
  94         platform. As per bug
  95         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=855">
  96                 http://bugzilla.remotesensing.org/show_bug.cgi?id=855</a>
  97
  98         <li> tif_dirinfo.c: Added support for ClipPath, XClipPathUnits
  99         and YClipPathUnits tags.
 100
 101         <li> tif_dirinfo.c, tif_dir.h, tif_dir.c, tif_print.c: Make
 102         DocumentName, Artist, HostComputer, ImageDescription, Make, Model,
 103         Copyright, DateTime, PageName, TextureFormat, TextureWrapModes and
 104         TargetPrinter tags custom.
 105
 106         <li> tif_jpeg.c: Cleanup the codec state depending on TIFF_CODERSETUP
 107         flag (to fix memory leaks).
 108
 109         <li> tif_dirwrite.c: Use tdir_count when calling
 110         TIFFCvtNativeToIEEEDouble() in the TIFFWriteDoubleArray() function as
 111         per bug <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=845">
 112         http://bugzilla.remotesensing.org/show_bug.cgi?id=845</a>
 113
 114         <li> tif_dirinfo.c, tif_print.c: TIFFFetchByteArray() returns
 115         uint16 array when fetching the BYTE and SBYTE fields, so we should
 116         consider result as pointer to uint16 array and not as array of chars.
 117         As per bug
 118         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=831">
 119                 http://bugzilla.remotesensing.org/show_bug.cgi?id=831</a>
 120
 121         <li> tif_dir.c: More efficient custom tags retrieval as per bug
 122         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=830">
 123                 http://bugzilla.remotesensing.org/show_bug.cgi?id=830</a>
 124
 125         <li> tif_win32.c: Use FILE_SHARE_READ | FILE_SHARE_WRITE share
 126         mode in CreateFile() call as per bug
 127         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=829">
 128         http://bugzilla.remotesensing.org/show_bug.cgi?id=829</a>
 129
 130         <li> tif_jpeg.c: Substantial fix for addtiffo problems with
 131         JPEG encoded TIFF files.  Pre-allocate lots of space for jpegtables
 132         in directory.
 133
 134         <li> tif_dirread.c: Changed the code that computes
 135         stripbytecount[0] if it appears bogus to ignore if stripoffset[0] is
 136         zero. This is a common case with GDAL indicating a "null" tile/strip.
 137
 138         <li> tif_jpeg.c: added LIB_JPEG_MK1 support in JPEGDecodeRaw().
 139
 140         <li> tif_dirread.c: Ensure that broken files with too many
 141         values in PerSampleShorts, TIFFFetchPerSampleLongs and
 142         TIFFFetchPerSampleAnys work ok instead of crashing.
 143         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=843">
 144         http://bugzilla.remotesensing.org/show_bug.cgi?id=843</a>
 145
 146         <li> tif_predict.h, tif_predict.c: Added ability to decode and encode
 147         floating point predictor, as per TIFF Technical Note 3.
 148         See http://chriscox.org/TIFF_TN3_Draft2.pdf for details.
 149
 150         <li> tiffio.h, tiffiop.h, tif_dir.c, tif_read.c, tif_swab.c:
 151         Added _TIFFSwab24BitData() and TIFFSwabArrayOfLong() functions used to
 152         swap 24-bit floating point values.
 153
 154         <li> tiff.h: Added predictor constants.
 155
 156         <li> tiffiop.h, tif_dir.c: Use uint32 type for appropriate values
 157         in _TIFFVSetField() function. Inspired by the bug
 158         <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=816">
 159                 http://bugzilla.remotesensing.org/show_bug.cgi?id=816</a>
 160
 161         <li> tif_open.c: Do not read header in case the output file should
 162         be truncated (Ron).
 163
 164         <li> tif_dirinfo.c, tif_config.h.vc: Use lfind() instead of bsearch()
 165         in _TIFFFindFieldInfoByName() function (Ron).
 166
 167         <li> tif_dir.c, tif_print.c: Properly handle all data types in custom
 168         tags.
 169
 170         <li> dirinfo.c: Added DNG tags.
 171
 172         <li> tiff.h: Added missed DNG tag (LensInfo); added DNG 1.1.0.0 tags.
 173
 174         <li> tif_dir.c, tif_print.c: Added Support for custom tags, passed
 175         by value.
