- Update to 4.7.0:
* This version restores in the default build the availability of
the tools that had been dropped in v4.6.0
See https://libtiff.gitlab.io/libtiff/rfcs/rfc2_restoring_needed_tools.html#rfc2-restoring-needed-tools
* Software configuration changes:
+ autoconf build: configure.ac: avoid -Werror passed to CFLAGS to interfere with feature detection
+ autoconf build: fix error when running make clean (fixes issue #630)
+ autoconf build: back off the minimum required automake version to 1.11
+ autoconf.ac: fix detection of windows.h for mingw (fixes issue #605)
+ libtiff-4.pc: Fix Requires.private missing Lerc. It provides a .pc file
starting from version 4 (in autoconf builds, we assume that liblerc is at least version 4)
+ CMake: Fix TIFF_INCLUDE_DIRS
+ CMake: MinGW compilers don't need a .def file for shared library
+ CMake: move libdeflate and Lerc to Requires.private
+ CMake: enable resource compilation on all Windows.
* Library changes:
+ Add TIFFOpenOptionsSetMaxCumulatedMemAlloc(). This function complements
TIFFOpenOptionsSetMaxSingleMemAlloc() to define the maximum cumulated memory
allocations in byte, for a given TIFF handle, that libtiff internal memory
allocation functions are allowed.
+ TIFFWriteDirectory(): Avoid overwriting following data if an IFD is enlarged.
+ TIFFXYZToRGB: avoid integer overflow (fixes issue #644)
+ uv_decode() and uv_encode(): avoid potential out-of-bounds array index (fixes issue #645)
+ Fix cases where tif_curdir is set incorrectly. Fix cases where the current directory number (tif_curdir)
is set inconsistently or incorrectly, depending on the previous history.
+ TIFFRead[Scanline/EncodedStrip/EncodeTile]: 0-initialize output buffer if setupdecode fails ;
most codecs: zero-initialize (not-yet-written parts of) output buffer if failure (fixes issue #375)
+ OJPEG: reset subsampling_convert_state=0 in OJPEGPreDecode (fixes issue #183)
+ ThunderRLE: fix failure when decoding last run. Bug seen with GhostPDL
+ LERC codec: deal with issues with multi-band PlanarConfig=Contig and NaN values
