2014-08-22Ensure that tjFree() is used for any JPEG buffers that might have been ↵dcommander
dynamically allocated by the compress/transform functions. To keep things simple, we use tjAlloc() for the statically-allocated buffer as well, so that tjFree() can always be used to free the buffer, regardless of whether it was allocated by tjbench or by the TurboJPEG library. This fixes crashes that occurred on Windows when running tjunittest or tjbench with the -alloc flag. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1383 632fc199-4ca6-4c93-a231-07263d6284db
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

2014-03-10When tjDecodeYUV() is used with a "fresh" decompressor instance (one that ↵dcommander
hasn't been previously used to decompress a JPEG image), then it needs comps_in_scan, data_precision, and the quantization tables to be defined. This patch also extends TJUnitTest to check for this error. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1143 632fc199-4ca6-4c93-a231-07263d6284db
2014-03-08Silence valgrind false positives about uninitialized values. Even with this ↵dcommander
patch, valgrind still complains about uninitialized values when decompressing or decoding to a buffer with an alpha-enabled colorspace. Not sure why this happens, but it occurs in libjpeg-turbo 1.3 as well, and only when the x86/x86-64 SIMD code is being used. It is my belief that these remaining warnings are also false positives, because if the output buffer is memset to all 0's prior to invoking tjDecodeYUV()/tjDecompress(), no errors are reported. If any of the alpha channel bits were in fact not being initialized, then they would still be 0 after invoking tjDecodeYUV()/tjDecompress(), and TJUnitTest would report an error. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1142 632fc199-4ca6-4c93-a231-07263d6284db

2014-02-28Implement a YUV decode function in the TurboJPEG API, to be symmetric with ↵dcommander

2014-02-28Remove benchmarks. They were originally intended as a way of measuring ↵dcommander
overhead for small compress/decompress operations, but using TJBench with a small image is a better way to accomplish that. git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1131 632fc199-4ca6-4c93-a231-07263d6284db
2014-02-11Fix an issue that prevented tjEncodeYUV3() and TJCompressor.encodeYUV() from ↵dcommander
working properly if the source image was very tiny. Basically, jpeg_start_compress() was attempting to write the JPEG headers, which was overrunning the YUV buffer. This patch removes the call to jpeg_start_compress() in tjEncodeYUV3() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.) git-svn-id: svn://svn.code.sf.net/p/libjpeg-turbo/code/trunk@1118 632fc199-4ca6-4c93-a231-07263d6284db
