Welcome.rtf Wordsmithing; Remove mention of TurboJPEG/IPP-- it is no longer a relevant comparison, since the version of IPP on which TurboJPEG/IPP was based is now quite old, and TurboJPEG/IPP is no longer distributed or supported by The VirtualGL Project; Include information about mathematical incompatibilities with jpeg-8 2013-01-10 11:47:39 +00:00

libjpeg-turbo.nsi.in Oops. We need to delete the new copy of turbojpeg.dll in the binary directory. Also add quotes to InstDir to allow installing under "c:\Program Files\", and remove unnecessary quotes in the Delete directives. 2013-09-20 01:11:40 +00:00
libjpeg-turbo.spec.in Make sure the RPM provides "libjpeg-turbo" as well, for backward compatibility (the TurboVNC RPM build, in particular, checks for this.) 2013-05-04 04:48:27 +00:00

\f0\fs24 \cf0 libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, x86-64, and ARM systems.  On such systems, libjpeg-turbo is generally 2-4x 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.\
