On such systems, libmozjpeg is generally 2-4x as fast as libjpeg, all else being equal. On other types of systems, libmozjpeg can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libmozjpeg rivals that of proprietary high-speed JPEG codecs.\ \ libmozjpeg implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libmozjpeg 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.\ \ libmozjpeg was forked from libjpeg-turbo. 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.\ }
