- c69a1cd If libjpeg-turbo is configured with a non-default prefix, such as /usr, then use the docdir variable defined by autoconf 2.60 and later, if available. This will, for instance, install the documentation under /usr/share/doc/libjpeg-turbo by default if prefix=/usr, unless docdir is overridden. When using earlier versions of autoconf, docdir is set to ${datadir}/doc, as it always has been. by DRC · 9 years ago
- c60d662 Some clarifications (actually MIPS doesn't implement the float DCT/IDCT using SIMD instructions) by DRC · 9 years ago
- 3af282d Make the floating point regression tests optional. It has been known for quite some time that these tests do not always generate the same results unless there is full SIMD coverage of the floating point algorithms in libjpeg-turbo. Further research reveals that there are basically three expected results: the results from our SSE SIMD extensions (which are slightly more accurate than the C code), results from the C code when running on a 32-bit FPU (or when using SSE instructions on an x86-64 CPU, which is the default with GCC), and results from the C code when running on a 64-bit FPU (which presumably uses double-precision arithmetic by default.) There is basically no way to determine which type of math will be used prior to run time, so it's best to just let the developers specify which result they expect on their particular system. by DRC · 9 years ago
- dd7f03b In the process of developing the AltiVec extensions, it was discovered that the normal regression tests aren't sufficient to test the behavior of the library with very small image sizes and when compressing from/decompressing to a subregion of a larger image buffer. Thus, an additional regression test was added that takes advantage of the tiled compression/decompression feature in tjbench. This is being back-ported to the 1.4.x branch primarily to verify that there are no lingering issues in the existing SIMD extensions. by DRC · 9 years ago
- cbc4b53 Add separate pseudo-targets for the TurboJPEG and libjpeg regression tests, for those times when you just don't want to sit through 11 iterations of TJUnitTest to find out that your algorithm is broken. by DRC · 9 years ago

- 684ace1 Extend tjbenchtest so that it tests the dynamic JPEG buffer allocation feature in TurboJPEG. Disable the tiling feature in TJBench whenever dynamic buffer allocation is enabled (because the tiling feature requires a separate buffer for each tile, using it successfully with dynamic buffer allocation would require a separate TurboJPEG compressor instance for each tile, and it's not worth going to that trouble right now.) by DRC · 10 years ago
- aee4f72 12-bit JPEG support by DRC · 10 years ago
- 78df2e6 Add support for decompressing to RGB565 (16-bit) pixels by DRC · 10 years ago
- 715bb41 Port the more accurate (and slightly faster) floating point IDCT implementation from jpeg-8a and later. New research revealed that the SSE/SSE2 floating point IDCT implementation was actually more accurate than the jpeg-6b implementation, not less, which is why its mathematical results have always differed from those of the jpeg-6b implementation. This patch brings the accuracy of the C code in line with that of the SSE/SSE2 code. by DRC · 10 years ago

- 7a6ed07 Extend YUVImage class to allow reuse of the same buffer with different metadata; port TJBench changes that treat YUV encoding/decoding as an intermediate step of the JPEG compression/decompression pipeline rather than a separate test case; add YUV encode/decode tests to the Java version of tjbenchtest by DRC · 10 years ago

- 4b50928 Back-port code from jpeg-8 that removes unpopulated (and unneeded) tables for AC and DC coefficients when generating progressive JPEG files with arithmetic coding. This should make such files bitwise compatible with jpeg-8, barring any other mathematical differences listed in README-turbo.txt.

- 7175e51 Further enhancements/fixes to the packaging system: by DRC · 11 years ago
- 764e1e2 Overhaul Linux/Unix packaging system, primarily to avoid conflicts with vendor-supplied libjpeg-turbo packages (such as in Fedora and RHEL 6.) This also streamlines the packaging system somewhat, since it is no longer necessary to move the TurboJPEG libraries into the system library directory. Relocating those libraries was originally done to provide backward compatibility with TurboJPEG/IPP, but that package is long obsolete, and the software that formerly used it has been linking statically with libjpeg-turbo for quite some time. by DRC · 11 years ago
- 0bf58f2 Include a C version of md5cmp rather than depending on an external md5sum binary, since md5sum is not available on all platforms (specifically, it doesn't exist on FreeBSD, and it has to be installed via MacPorts on OS X.) by DRC · 11 years ago
- a2a2cd6 Include ARM v7s (iPhone 5, iPad 4) support in the universal libjpeg/libturbojpeg libraries distributed with our official binary package for OS X. by DRC · 11 years ago
- 6da61db Fix several issues with SRPM generation: (1) ensure that all relevant configure arguments get passed down to the configure command line in the generated spec file, (2) adjust the file manifest in the spec to accommodate the differing "age" version whenever the in-memory source/dest managers are used, and (3) fix an issue with the value of SO_MAJOR_VERSION passed down to the configure command line in the generated spec file (SO_MAJOR_VERSION has to remain pure, so we use a different variable to pass down the combined "current+age" value to libtool in Makefile.am.) by DRC · 11 years ago
- ab70623 Implement in-memory source/destination managers even when not emulating the libjpeg v8 API/ABI by DRC · 11 years ago
- 0f43551 Fix 'make dist' by DRC · 11 years ago
- 211d1e7 Consolidate the MD5 sums into one location and add a --without-turbojpeg switch to the Un*x build to allow building libjpeg-turbo without the TurboJPEG/OSS wrapper library. These modifications were supposed to lay the ground work for adding compile-time-selectable 12-bit JPEG support, but unfortunately there are deeper issues that prevent the implementation of that feature right now (namely, some of the modifications made to the C code to support the SIMD code are apparently not 12-bit-friendly.) by DRC · 11 years ago
- f29ffd3 Modify 'make test' so that it uses MD5 sums instead of reference images. This eliminates the need to check most of the test images into the repository, which keeps the source tarball to a reasonable size. by DRC · 11 years ago
- 2f12d7a Also remove mention of install.txt and filelist.txt in the build system and README. by DRC · 11 years ago
- fac3bea Add a Java version of TJBench and extend the TurboJPEG Java API to support it (this involved adding a polymorphic method in TJCompressor that accepts x and y offsets into a larger buffer, similar to the previous modification that had been done to TJDecompressor.) by DRC · 12 years ago

- 9b28def Completely refactored the TurboJPEG C API so that it uses pixel formats 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. by DRC · 13 years ago
