- Update to version 2.3.4:
* Changed
- Replaced legacy test images
From version 2.3.3:
* Fixed
- [#167](https://github.com/team-charls/charls/issues/167),
Decoding\Encoding fails on IBM s390x CPU
(Big Endian architecture)
* Changed

of the Linux and macOS builds.
* Wed Feb 02 2022 Asterios Dramis <[email protected]>
- Update to version 2.3.2:
* Fixed
- [#160](https://github.com/team-charls/charls/issues/160),
warning: cast from ‘unsigned char*’ to ‘uint16_t*’ increases
required alignment of target type
- [#161](https://github.com/team-charls/charls/issues/161),
warning: useless cast to type ‘size_t’ {aka ‘unsigned int’}
[-Wuseless-cast]
* Changed
- Updates to the CMakeLists.txt for Unix builds (except macOS)
to hide more symbols from the shared library.
- C++14 is now the minimum version instead of explicitly
required. This allows consuming applications more
flexibility. Typically CMake will select the latest C++
standard version that used C++ compiler supports.
From version 2.3.1:
* Fixed
- [#155](https://github.com/team-charls/charls/issues/155),
charls::jpegls_decoder::decode: 2 overloads have similar
conversions in v2.3.0
From version 2.3.0:
* Added
- The encoder API has been extended with a rewind method that
can be used to re-use a configured encoder to encode multiple
images in a loop.
- Added support to decode JPEG-LS images that use restart
markers
[#92](https://github.com/team-charls/charls/issues/92).
- Added support to write and read comment (COM) segments
[#113](https://github.com/team-charls/charls/issues/113).
- Added support to encode/decode oversized images (width or
height larger then 65535).
- Extended the validation of the encoded JPEG-LS byte stream
during decoding.
- Added support to encode JPEG-LS images with:
* The option to ensure the output stream has an even size.
* The option to write the CharLS version number as a comment
(COM segment) to the output stream.
* The option to write the coding parameters to the output
stream if the bits per pixel are larger then 12 (enabled by
default).
- Usage of compiler specific attributes on the public API as
replacement for ``[[nodiscard]]`` (which is a C++17 feature).
* Fixed
- [#84](https://github.com/team-charls/charls/issues/84),
Default preset coding parameters not computed for unset
values.
- [#102](https://github.com/team-charls/charls/issues/102),
CMake find_package(charls 2.2.0 REQUIRED) not working.
* Changed
- CMakeSettings.json has been replaced with CMakePresets.json.
- Non default coding parameters are explicitly stored in the
output stream during encoding.
- GCC shared library release builds are now using LTO (Link
Time Optimization).
- Some functions use compiler intrinsics for slightly better
performance.
- Removed support for openSUSE <= 13.2/Leap 42.
* Mon Mar 01 2021 Asterios Dramis <[email protected]>
- Update to version 2.2.0:
* Added
- Added pkg-config charls.pc file to help in detect the CharLS
library (see #76)
- Added standard CMake variable BUILD_SHARED_LIBS as an option
to make it 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 analyzer in the MSVC and 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 add_link_options
- 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
- Added pkgconfig build requires.
* Sun Aug 09 2020 andy great <[email protected]>
- Update to version 2.1.0.
* Added
* Two new C++ classes (jpegls_encoder \ jpegls_decoder) have
been added to make it much easier to use CharLS from C++
* A new C API (charls_xxx functions) was added to provide a
more stable ABI for future updates. The old API calls are
internally forwarded to the new API.
* CharLS can now read and write JPEG-LS standard SPIFF headers
* Support has been added to detect the unsupported JPEG-LS
extension (ISO/IEC 14495-2) SOF_57 marker and IDs in LSE
marker
* Support has been added to encode\decode 4 component images
in all interleave modes
* Deprecated
* The legacy 1.x\2.0 C API has been marked as deprecated. This
legacy API will be maintained until the next major upgrade.
* Future 2.x updates will start to mark the legacy types and
functions with the C++ [[deprecated]] attribute.
* Changed
* charls_error has been replaced by a C++11 compatible
jpegls_errc error code enum design
* The included C and C++ sample have been updated to use the
new C\C++ API
* Improved the validation of the JPEG-LS stream during
decoding
* The referenced NuGet packages of the .NET wrapper assembly
are updated to their latest versions
* Removed
* Support to write JFIF headers during encoding has been
removed. JFIF headers were already skipped when present
during decoding.
* SPIFF headers should be used when creating standalone .jls
files
* Support for .NET Code Contracts has been removed as this
technology is being phased out by Microsoft
* Fixed
* Fixed #7, How to compile CharLS with Xcode has been
documented in the Wiki
* Fixed #44, Only the API functions should be exported from a
Linux shared library
* Fixes #35, Encoding will fail if the bit per sample is
greater than 8, and a custom RESET value is used
* Fixes #51, The default threshold values are not corrected
computed for 6 bit images or less
* Fixed the ASSERT in the ModuloRange function, which would
trigger false assertions in debug builds
* Thu Jul 13 2017 [email protected]
- Build with gcc6, fix build failure for Leap
* Mon Jul 10 2017 [email protected]
- Fix RPM group.
* Thu Jul 06 2017 [email protected]
- Update to version 2.0.0:
Bug fixes
* #10 - Fixed the problem that "output buffer to small" was not
detected when writting encoded bytes to a fixed output buffer.
This could cause memory corruption problems.
* #11 - Update charlstest to return EXIT_SUCCESS/FAILURE
* Fixed the issue that DecodeToPnm would set
params.colorTransform = ColorTransformation::BigEndian but the
library didn’t support this option during decoding.
Misc
* Updated the source code to C++ v14.
* Refactored several API's to make usage of the library easier.
- Removed unzip build requirement (not needed anymore).
- Require gcc >= 5.0 (for C++ v14).
- Removed the following patches (not needed anymore):
charls_add_cmake_install_target.patch
charls_add_sharedlib_soname.patch
charls_fix_tests.patch
* Tue Nov 20 2012 [email protected]
- Fix the SLES build (%make_install is not expanded)
