2012-06-29Add flags to the TurboJPEG API that allow the caller to force the use of ↵dcommander
either the fast or the accurate DCT/IDCT algorithms in the underlying codec. git-svn-id: https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo@851 3789f03b-4d11-0410-bbf8-ca57d06f2519
2011-12-19Added new alpha channel colorspace constants/pixel formats, so applications ↵dcommander
can specify that they need the unused byte in a 4-component RGB output buffer set to 0xFF when decompressing. git-svn-id: https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo@732 3789f03b-4d11-0410-bbf8-ca57d06f2519

2011-05-24Add new API functions, tjAlloc() and tjFree(), which allow memory to be ↵dcommander
allocated and freed using a method of the library's choosing. At the moment, the primary purpose for this is to avoid allocating/freeing memory across the DLL boundary on Windows. git-svn-id: https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo@634 3789f03b-4d11-0410-bbf8-ca57d06f2519

2011-05-21Clean up constants so that flags, pixel formats, etc. are clearly ↵dcommander
differentiated; Update documentation accordingly; Name the enums to make it easier to reference them in the docs and clean up the references accordingly; Set Doxygen option to force a detailed description for the constants to always be generated git-svn-id: https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo@617 3789f03b-4d11-0410-bbf8-ca57d06f2519
2011-05-21Completely refactored the TurboJPEG C API so that it uses pixel formats ↵dcommander
instead of the clunky pixel size + flags combination to define the pixel size and component order. tjCompress2() and tjTransform() can also now grow the JPEG buffer as needed, which can allow programs to save memory by not pre-allocating the "worst-case" buffer size calculated by TJBUFSIZE(). Converted API documentation to Doxygen. There is no legacy code remaining, so the refactored version of the library has been re-licensed under a BSD-style license. git-svn-id: https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo@616 3789f03b-4d11-0410-bbf8-ca57d06f2519

2011-03-02Since lossless transforms have such a high fixed performance cost, implement ↵dcommander
a mechanism for performing more than one at a time on the same source image. git-svn-id: https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo@488 3789f03b-4d11-0410-bbf8-ca57d06f2519
