- 95e4cb2 Since we now have a complete set of YUV functions, TJBench can be greatly simplified. It now tests YUV encoding/decoding as an intermediate step of JPEG compression/decompression, which eliminates the need for a separate YUV mode. Several other things have been streamlined in the process. by DRC · 11 years ago

Something in the recesses of my brain is telling me that I tried this before and it failed under some circumstances, but it must have been a bug in an older CMake implementation. CMake 2.8.8 and later seem to work fine with this patch. This patch also updates the minimum required version to 2.8.8, because 2.8.8 fixed another issue that was preventing the SIMD code from building under MSVC 2010 and later. by DRC · 11 years ago

- 7d9f758 For now, punt on trying to support fancy upsampling in tjDecodeYUV(). Fancy upsampling requires context rows and other refinements, which are difficult to implement correctly with the algorithm we're using. Longer-term, supporting fancy upsampling would probably require using the main buffer that libjpeg allocates. by DRC · 11 years ago
- 15c0876 Fix additional uninitialized values reported by valgrind by DRC · 11 years ago
- c901449 When tjDecodeYUV() is used with a "fresh" decompressor instance (one that 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. by DRC · 11 years ago
- 20e158d Silence valgrind false positives about uninitialized values. Even with this 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. by DRC · 11 years ago

- 693f4a5 Fix an issue that prevented tjEncodeYUV2() and TJCompressor.encodeYUV() from 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 tjEncodeYUV2() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler.
