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
