| 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, x86-64, and |
| Arm 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. |
