|
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> |

|
99 and YClipPathUnits tags. |
|
100 |

|
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 |

|
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"> |
|

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. |
|
176 |
|
177 <li> tiff.h, tif_dirinfo.c, tiffiop.h: Added EXIF related tags. |
