##Project Description 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.
###Features
- High performance C++ implementation with a C interface to ensure maximum interopability.
- Supports Windows, Linux and Solaris in 32 bit and 64 bit.
- Includes a wrapper class for .NET
##About JPEG-LS JPEG-LS (ISO-14495-1/ITU-T.87) is a standard derived from the Hewlett Packard LOCO algorithm. JPEG LS has low complexity (meaning fast compression) and high compression ratios, similar to JPEG 2000. JPEG-LS is more similar to the old Lossless JPEG than to JPEG 2000, but interestingly the two different techniques result in vastly different performance characteristics.

##Building CHARLS
###Primary development
Primary development is done on Windows with Visual Studio 2015. Optimized projects and solution files are available for this environment.
All other platforms are supported by cmake. CMake is a cross platform open source build system that generate project\make files for a large set of environments.
