2014-08-21If the output buffer in the TurboJPEG destination manager was allocated by ↵dcommander
the destination manager and is being reused from a previous compression operation, then we need to get the buffer size from the previous operation, since the calling program doesn't know the actual buffer size. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1368 632fc199-4ca6-4c93-a231-07263d6284db
2014-08-17Refactored YUVImage Java class so that it supports both unified YUV image ↵dcommander
buffers as well as separate YUV image planes; modified the JNI functions accordingly and added new helper functions to the TurboJPEG C API (tjPlaneWidth(), tjPlaneHeight(), tjPlaneSizeYUV()) to facilitate those modifications; changed potentially confusing "component width" and "component height" terms to "plane width" and "plane height" and modified variable names in turbojpeg.c to reflect this; numerous other documentation tweaks git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1360 632fc199-4ca6-4c93-a231-07263d6284db

2014-08-12Reformat TurboJPEG C API documentation to improve ease of maintenance and to ↵dcommander
make it more consistent with the javadoc formatting; fix minor error in tjCompressFromYUV() prototype. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1344 632fc199-4ca6-4c93-a231-07263d6284db
2014-08-11Extend the TurboJPEG C API to support handling YUV images stored in separate ↵dcommander
image planes instead of a unified buffer git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1343 632fc199-4ca6-4c93-a231-07263d6284db
2014-08-10Clean up and consolidate notes regarding the YUV image format. This also ↵dcommander
corrects a factual error regarding the padding of the luminance plane-- because we now support 4:1:1, the component width is not necessarily padded to the nearest multiple of 2 if horizontal subsampling is used. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1342 632fc199-4ca6-4c93-a231-07263d6284db

2014-08-10Make the documentation more readable by displaying fixed-width text (which ↵dcommander
is used to refer to variables and functions) in a different color. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1339 632fc199-4ca6-4c93-a231-07263d6284db
2014-03-15As with tjDecompressToYUV*(), tjCompressFromYUV() also conditionally uses an ↵dcommander
intermediate buffer if the source image dimensions do not fall on MCU boundaries. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1170 632fc199-4ca6-4c93-a231-07263d6284db
2014-02-28Implement a YUV decode function in the TurboJPEG API, to be symmetric with ↵dcommander

2013-11-25Per the conventions of the image compression and digital video communities, ↵dcommander
use "YCbCr" to describe the JPEG colorspace and "YUV" to describe an image format consisting of Y, Cb, and Cr planes (this partially reverts r960.) git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1093 632fc199-4ca6-4c93-a231-07263d6284db
2013-10-31Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were ↵dcommander
originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1072 632fc199-4ca6-4c93-a231-07263d6284db

2013-04-26Subtle point, but since libjpeg-turbo 1.3 now supports scaling factors > 1, ↵dcommander
the width and height specified in tjDecompress2() are not necessarily smaller than the JPEG width/height. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@958 632fc199-4ca6-4c93-a231-07263d6284db

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: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@634 632fc199-4ca6-4c93-a231-07263d6284db

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: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@616 632fc199-4ca6-4c93-a231-07263d6284db
