| Significant changes since 1.0.1 |
| =============================== |
| |
| [1] Added emulation of the libjpeg v7 and v8b APIs and ABIs. See |
| README-turbo.txt for more details. This feature was sponsored by CamTrace SAS. |
| |
| [2] Created a new CMake-based build system for the Visual C++ and MinGW builds. |
| |
| [3] TurboJPEG/OSS can now compress from/decompress to grayscale bitmaps. |
| |
| [4] jpgtest can now be used to test decompression performance only. |
| |
| [5] If the default install prefix (/opt/libjpeg-turbo) is used, then |
| 'make install' now creates /opt/libjpeg-turbo/lib32 and |
| /opt/libjpeg-turbo/lib64 sym links to duplicate the behavior of the binary |
| packages. |
| |
| [6] All symbols in the libjpeg-turbo dynamic library are now versioned, even |
| when the library is built with libjpeg v6b emulation. |
| |
| [7] Added arithmetic encoding and decoding support (can be disabled via |
| configure or CMake options) |
| |
| [8] Added a TJ_YUV flag to TurboJPEG/OSS which causes both the compressor and |
| decompressor to output planar YUV images. |
| |
| [9] Added an extended version of tjDecompressHeader() to TurboJPEG/OSS which |
| allows the caller to determine the type of subsampling used in a JPEG image. |
| |
| [10] Added further protections against invalid Huffman codes. |
| |
| |
| Significant changes since 1.0.0 |
| =============================== |
| |
| [1] The Huffman decoder will now handle erroneous Huffman codes (for instance, |
| from a corrupt JPEG image.) Previously, these would cause libjpeg-turbo to |
| crash under certain circumstances. |
| |
| [2] Fixed typo in SIMD dispatch routines which was causing 4:2:2 upsampling to |
| be used instead of 4:2:0 when decompressing JPEG images using SSE2 code. |
| |
| [3] configure script will now automatically determine whether the |
| INCOMPLETE_TYPES_BROKEN macro should be defined. |
| |
| |
| Significant changes since 0.0.93 |
| ================================ |
| |
| [1] 2983700: Further FreeBSD build tweaks (no longer necessary to specify |
| --host when configuring on a 64-bit system) |
| |
| [2] Created sym. links in the Unix/Linux packages so that the TurboJPEG |
| include file can always be found in /opt/libjpeg-turbo/include, the 32-bit |
| static libraries can always be found in /opt/libjpeg-turbo/lib32, and the |
| 64-bit static libraries can always be found in /opt/libjpeg-turbo/lib64. |
| |
| [3] The Unix/Linux distribution packages now include the libjpeg run-time |
| programs (cjpeg, etc.) and man pages. |
| |
| [4] Created a 32-bit supplementary package for amd64 Debian systems which |
| contains just the 32-bit libjpeg-turbo libraries. |
| |
| [5] Moved the libraries from */lib32 to */lib in the i386 Debian package. |
| |
| [6] Include distribution package for Cygwin |
| |
| [7] No longer necessary to specify --without-simd on non-x86 architectures, and |
| unit tests now work on those architectures. |
| |
| |
| Significant changes since 0.0.91 |
| ================================ |
| |
| [1] 2982659, Fixed x86-64 build on FreeBSD systems |
| |
| [2] 2988188: Added support for Windows 64-bit systems |
| |
| |
| Significant changes since 0.0.90 |
| ================================ |
| |
| [1] Added documentation to .deb packages |
| |
| [2] 2968313: Fixed data corruption issues when decompressing large JPEG images |
| and/or using buffered I/O with the libjpeg-turbo decompressor |
