This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:

Major changes

  • Fixed important bug in custom tags handling code.

Software configuration changes

  • Applied patch from Patrick Welche (all scripts moved in the config and m4 directories).

  • SConstruct, libtiff/SConstruct: Added the first very preliminary support for SCons software building tool (http://www.scons.org/). This is experimental infrastructure and it will exist along with the autotools stuff.

  • port/lfind.c: Added lfind() replacement module.

Library changes

  • tif_dir.c: When prefreeing tv->value in TIFFSetFieldV() also set it to NULL to avoid double free when re-setting custom string fields as per: Remote Sensing bugzilla #922 [no longer available]

  • 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, libtiff/tif_dirinfo.c: Do not upcast BYTE to SHORT in the TIFFFetchByteArray(). Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag() instead as per bug Remote Sensing bugzilla #831 [no longer available]

    Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag() instead.

  • tif_print.c: Fixed printing of the BYTE and SBYTE arrays.

  • 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, libtiff/tif_dir.h, libtiff/tif_dirinfo.c, libtiff/tif_print.c: Make FieldOfViewCotangent, MatrixWorldToScreen, MatrixWorldToCamera, ImageFullWidth, ImageFullLength and PrimaryChromaticities tags custom.

Tools changes

  • tiffcp.c: Fixed WhitePoint tag copying.

Contributed software changes

  • tiffdump.c: Added support for TIFF_IFD datatype.

  • addtiffo/tif_overview.c, addtiffo/tif_ovrcache.c, addtiffo/tif_ovrcache.h: Make overviews working for contiguous images.
