- Description: A SIMD-accelerated JPEG codec that provides both the libjpeg and TurboJPEG APIs
- libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate
- baseline JPEG compression and decompression on x86, x86-64, ARM, PowerPC, and
- MIPS systems, as well as progressive JPEG compression on x86 and x86-64
- systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg,
- all else being equal. On other types of systems, libjpeg-turbo can still
- outperform libjpeg by a significant amount, by virtue of its highly-optimized
- Huffman coding routines. In many cases, the performance of libjpeg-turbo
- rivals that of proprietary high-speed JPEG codecs.
- .
- libjpeg-turbo implements both the traditional libjpeg API as well as the less
- powerful but more straightforward TurboJPEG API. libjpeg-turbo also features
- colorspace extensions that allow it to compress from/decompress to 32-bit and
- big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java
- interface.
- .
- libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated
- derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and
- VirtualGL projects made numerous enhancements to the codec in 2009, and in
- early 2010, libjpeg-turbo spun off into an independent project, with the goal
- of making high-speed JPEG compression/decompression technology available to a
- broader range of users and developers.
