+# CharLS 1.x, a JPEG-LS library
+
+## 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.
+
+IMPORTANT: this is the 1.x branch, which is C++03 compatible and in maintenaince mode to support platforms on which a C++14 compiler is not available. The general recommendation is to use the releases from the master branch.
+
+### Features
+
+* High performance C++03 implementation with a C interface to ensure maximum interopability.
+* Supports Windows, Linux and Solaris in 32 bit and 64 bit.
+
+## About JPEG-LS
+
+JPEG-LS (ISO-14495-1:1999/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. 
+[Wikipedia on lossless JPEG and JPEG-LS](en.wikipedia.org/wiki/Lossless_JPEG)
+[Benchmarks JPEG-LS-Performance](charls.codeplex.com/wikipage?title=JPEG-LS-Performance&referringTitle=Home)
+
+## Building CHARLS
+
+### Primary development
+
+Primary development is done on Windows with Visual Studio 2017.
+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.
