- 976fd96 The x86/x86-64 SIMD extensions were originally designed to accommodate changing the value of RGB_*, but this apparently broke when RGB-to-gray colorspace conversion was accelerated. Further, the ARM NEON extensions have always assumed that JCS_RGB behaves identically to JCS_EXT_RGB. Rather than fix these issues, it makes more sense to just stop claiming that we support changing the values of RGB_*, since doing so is no longer necessary. by DRC · 10 years ago

- b775351 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.) by DRC · 10 years ago

CMake 2.8.8 and later seem to work fine with this patch.

- 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. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.) by DRC · 11 years ago

- 2885cf5 Further examination of the code reveals that this change is unnecessary. The histogram stores a count of each color in the image, so it will always contain at least one non-zero element, and thus the total can never be zero. Since the histogram is generated from the image data and not read from the header, there is no chance that header corruption would affect it. by DRC · 11 years ago

- c45653e Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1. by DRC · 11 years ago

In order to prevent this from happening again, specifying --with-simd now has the effect of forcing a SIMD build, and if this argument is specified, any issues encountered while enabling SIMD are treated as fatal. by DRC · 11 years ago
