DRC aee4f721 2014-08-09T23:06:07 12-bit JPEG support git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1337 632fc199-4ca6-4c93-a231-07263d6284db
DRC 5033f3e1 2014-05-18T18:33:44 Remove MS-DOS code and information, and adjust copyright headers to reflect the removal of features in r1307 and r1308. libjpeg-turbo has never supported MS-DOS, nor is it even possible for us to do so. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1312 632fc199-4ca6-4c93-a231-07263d6284db
DRC bc56b754 2014-05-16T10:43:44 Get rid of the HAVE_PROTOTYPES configuration option, as well as the related JMETHOD and JPP macros. libjpeg-turbo has never supported compilers that don't handle prototypes. Doing so requires ansi2knr, which isn't even supported in the IJG code anymore. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1308 632fc199-4ca6-4c93-a231-07263d6284db
DRC 52ded876 2014-05-15T20:30:16 Remove all of the NEED_SHORT_EXTERNAL_NAMES stuff. There is scant information available as to which linkers ever had a 15-character global symbol name limit. AFAICT, it might have been a VMS and/or a.out BSD thing, but none of those platforms have ever been supported by libjpeg-turbo (nor are such systems supported by other open source libraries of this nature.) git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1307 632fc199-4ca6-4c93-a231-07263d6284db
DRC b7753510 2014-05-11T09:36:25 Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons. They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.) git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/branches/1.3.x@1285 632fc199-4ca6-4c93-a231-07263d6284db

DRC 27fb3fc5 2012-01-28T01:48:07 Support additional scaling factors when decompressing git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@753 632fc199-4ca6-4c93-a231-07263d6284db
Pierre Ossman 5eb84ff9 2009-03-09T13:25:30 Add MMX SIMD implementation of computationally intensive routines. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@17 632fc199-4ca6-4c93-a231-07263d6284db
Pierre Ossman dedc42e2 2009-03-09T13:23:04 "Optimise" quantization step by replacing the division by a multiplication. This has no measurable difference right now but makes it possible to do SIMD implementations of this stage. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@16 632fc199-4ca6-4c93-a231-07263d6284db
Pierre Ossman 49dcbfbf 2009-03-09T10:37:20 Split up the forward DCT routine into three stages Divide it into sample conversion, DCT and quantization in order to easily provide alternative implementations of each stage. git-svn-id: svn+ssh://svn.code.sf.net/p/libjpeg-turbo/code/trunk@13 632fc199-4ca6-4c93-a231-07263d6284db
