2013-04-26Extend the TurboJPEG C API to support generating YUV images with arbitrary ↵DRC
padding and to support image scaling when decompressing to YUV git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@962 632fc199-4ca6-4c93-a231-07263d6284db

2013-04-26Subtle point, but since libjpeg-turbo 1.3 now supports scaling factors > 1, ↵DRC
the width and height specified in tjDecompress2() are not necessarily smaller than the JPEG width/height. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.3.x@957 632fc199-4ca6-4c93-a231-07263d6284db
2012-06-29Add flags to the TurboJPEG API that allow the caller to force the use of ↵DRC
either the fast or the accurate DCT/IDCT algorithms in the underlying codec. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@851 632fc199-4ca6-4c93-a231-07263d6284db
2011-12-19Added new alpha channel colorspace constants/pixel formats, so applications ↵DRC

2011-05-24Add new API functions, tjAlloc() and tjFree(), which allow memory to be ↵DRC
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: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@634 632fc199-4ca6-4c93-a231-07263d6284db

2011-05-21Clean up constants so that flags, pixel formats, etc. are clearly ↵DRC
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: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@617 632fc199-4ca6-4c93-a231-07263d6284db
2011-05-21Completely refactored the TurboJPEG C API so that it uses pixel formats ↵DRC
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: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@616 632fc199-4ca6-4c93-a231-07263d6284db

2011-03-02Since lossless transforms have such a high fixed performance cost, implement ↵DRC
a mechanism for performing more than one at a time on the same source image. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@488 632fc199-4ca6-4c93-a231-07263d6284db
