CharLS, a C++ JPEG-LS library implementation

Pure-managed, SIMD-accelerated image codecs for .NET: JPEG, PNG, WebP, TIFF, GIF, JPEG 2000 and JBIG2, plus EXIF and ICC. No native dependencies, NativeAOT-compatible; the JPEG decoder beats libjpeg-turbo on our benchmark corpus.

Zstandard (RFC 8878) rewritten in 100% safe Rust, byte-identical where applicable, but with a Rust-native API, SIMD, compression + decompression, no_std and modern parallelism.

Fast, memory-safe camera RAW decoder in Rust: ~40 formats, SIMD, GPU, WebAssembly, ICC colour management. CLI, C, C++, Python and JavaScript bindings.
