+
+
- tif_dir.c: Fixed up support for swapping "double complex"
+ values (128 bits as 2 64 bits doubles). GDAL gcore tests now
+ pass on bigendian (macosx) system.
+
+
- libtiff/{tif_dirread.c, tif_dirinfo.c}: Do not upcast BYTEs to
+ SHORTs in the TIFFFetchByteArray(). Remove TIFFFetchExtraSamples()
+ function, use TIFFFetchNormalTag() instead as per bug
+
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=831
+
+ Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag()
+ instead.
+
+

+
+
- tif_write.c: Do not check the PlanarConfiguration field in
+ the TIFFWriteCheck() function in case of single band images (as per
+ TIFF spec).
+
+
- libtiff/{tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_print.c}:
+ Make FieldOfViewCotangent, MatrixWorldToScreen, MatrixWorldToCamera,
+ ImageFullWidth, ImageFullLength and PrimaryChromaticities tags custom.
