A JPEG-LS library
http://charls.codeplex.com/
An optimized implementation of the JPEG-LS standard for lossless and
near-lossless image compression. JPEG-LS is a low-complexity standard that
matches JPEG 2000 compression ratios. In terms of speed, CharLS outperforms
open source and commercial JPEG LS implementations.

- 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* charls_error has been replaced by a C++11 compatible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
