Changes in TIFF v4.3.0 ====================== .. table:: References :widths: auto ====================== ========================================== Current Version v4.3.0 (:tag:`v4.3.0`) Previous Version :doc:`v4.2.0 ` Master Download Site ``_ Master HTTP Site #1 ``_ Master HTTP Site #2 ``_ Master HTTP Site #3 ``_ ====================== ========================================== This document provides a summary of significant changes made to the software between the *previous* and *current* versions (see above). A fully-detailed change summary is provided by the :file:`ChangeLog` file included in the release package and by the Git commit history: Major changes ------------- * Build and usage of the library and its utilities requires a C99 capable compiler. * New optional codec for the LERC (Limited Error Raster Compression) compression scheme. To have it available, configure libtiff against the SDK available at ``_ * CMake build: revamp of build scripts Software configuration changes ------------------------------ * cmake: revamp of the cmake build scripts. There are impacts on the case of some options. * cmake: update minimum version and policy version to 3.9. * Remove NMake build support. The functionality provided by the NMake build is now completely superseded by the CMake build. * Remove antiquated Scons and makefile.lcc build support. * Remove non-functional VMS and WinCE support. * :file:`autogen.sh` now updates :file:`config.guess` and :file:`config.sub` from master gnulib version. Library changes --------------- * Use of :c:type:`int8`, :c:type:`uint8`, :c:type:`int16`, :c:type:`uint16`, :c:type:`int32`, :c:type:`uint32`, :c:type:`int64`, :c:type:`uint64` typedefs is now deprecated. libtiff code and headers no longer use them, and use their C99 standard equivalents (with ``_t`` suffix). Those typedefs are still available, with deprecation warnings, but external code is strongly encouraged to use the corresponding C99 :file:`stdint.h` types. The deprecated types might be removed in a future release. * Removal of unused, or now useless due to C99 availability, functions in :file:`port/` * A few issues spotted by static code analysis tools fixed. Compiler warnings addressed. Tools changes ------------- * In usage text, insert a line of text summarizing each tool's purpose * tiff tools: made display of compression methods and their parameters conditional on their actual availability * :program:`tiff2ps`: exit the loop in case of error (#232) * :program:`tiff2pdf`: check that tiff_datasize fits in a signed :c:type:`tsize_t` (#202) * :program:`tiffsplit`: exit with :c:macro:`EXIT_FAILURE` if there are extra args on the command line * :program:`tiffcmp`: fix comparaison with pixels that are fractional number of bytes (#53) Contributed software changes ---------------------------- * :file:`iptcutil.c` - set ``#ifdef _WIN32`` (was ``#ifdef WIN32``, which failed at build time)
