|
|---|
| 102 | DocumentName, Artist, HostComputer, ImageDescription, Make, Model,
|
|---|
| 103 | Copyright, DateTime, PageName, TextureFormat, TextureWrapModes and

|---|
| 110 | TIFFCvtNativeToIEEEDouble() in the TIFFWriteDoubleArray() function as
|
|---|
| 111 | per bug <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=845">

|---|
| 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.

|
|---|
| 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().

|
|---|
| 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 |
|
|---|

|
|---|
| 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 |
|
|---|
