Summary

Feature and maintenance release.

Added

  • Added a pkg-config charls.pc file to help in detecting the CharLS library (see #76)
  • Added standard CMake variable BUILD_SHARED_LIBS as an option to make this option visible in the CMake GUI (see #66)
  • The PowerPC Little Endian (ppc64le) platform has been added as supported architecture

Fixed

  • Fixed #21, Building with UBSAN, will report runtime error: left shift
    of 4031 by 63 places cannot be represented in type 'long int'
  • Fixed #25, CharLS fails to read LSE marker segment after first SOS segment
  • Fixed #26, CharLS should only use the valid bits from the passed input buffer
  • Fixed #36, CharLS should remain stable from bad input (several issues found by fuzzy testing)
  • Fixed #60, Visual Studio 2015 C++ compiler cannot compile certain constexpr constructions
  • Fixed #62, Missing includes in jpegls_error.cpp when using libc++ (and not libstdc++)
  • Fixed #70, The C and C++ sample don't swap the pixels from a .bmp file horizontal
  • Fixed #79, Wrong JPEG-LS encoding when stride is non-default (stride != 0),
    component count > 1 and interleave_mode is none

Changed

  • The API has been extended with additional annotations to assist the static analyzers of the MSVC and the GCC/clang compilers
  • The size check for a Start Of Scan (SOS) segment is now exact for improved compatibility with fuzzy testing
  • The minimum support version of CMake is now 3.13 (was 3.9). 3.13 is needed for usage of the add_link_options statement
  • The Windows static library and DLL are now compiled with the Control Flow Guard (/guard:cf) option enabled for enhanced security
  • The .NET adapter has been upgraded to .NET 5 and moved to its own repository
    This has been done to make it possible to have different release cycles.

Removed

  • The legacy methods JpegLsEncodeStream, JpegLsDecodeStream and JpegLsReadHeaderStream have been removed as exported methods. These methods were not part of the public API and only used by by the charlstest application
