Name : CharLS Product : Fedora 13 Version : 1.0 Release : 1.fc13 URL : http://charls.codeplex.com/ Summary : An optimized implementation of the JPEG-LS standard Description : An optimized implementation of the JPEG-LS standard for loss less and near loss less image compression. JPEG-LS is a low-complexity standard that matches JPEG 2000 compression ratios. In terms of speed, CharLS outperforms open source and commercial JPEG LS implementations. JPEG-LS (ISO-14495-1/ITU-T.87) is a standard derived from the Hewlett Packard LOCO algorithm. JPEG LS has low complexity (meaning fast compression) and high compression ratios, similar to JPEG 2000. JPEG-LS is more similar to the old loss less JPEG than to JPEG 2000, but interestingly the two different techniques result in vastly different performance characteristics. -------------------------------------------------------------------------------- Update Information: Finally, the 1.0 release of CharLS! Compared to the beta, the following is changed/added: * Improved C++ standard compliance for compatibility with: o Visual C++ (Compilable with Visual Studio 2008, x86, x64, and ARM cpu's) o GCC for Linux x64/x86 (warning free in pedantic mode) o GCC for MinGWin o XCode o Big-Endian platforms o CPU's with aligned memory access requirements o many more (but not recently tested) * Improved security (prevent potentially exploitable crashes). Won't crash on random data. * Reduced memory use through DISABLE_SPECIALIZATIONS define (not enabled by default) * Header file can now be included from C++ and C source files * Added unit test for Dicom WG04 sample images (files not included) * Fixes to ensure CharLS streams are readable by Java JAI JPEG-LS code. * Added tolerance for non-standard padding bits -------------------------------------------------------------------------------- ChangeLog: * Thu Feb 3 2011 Mario Ceresa [email protected] CharLS 1.0-1 - Update to new version - Applied patch to fix bug http://charls.codeplex.com/workitem/7823 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program. Use su -c 'yum update CharLS' at the command line. For more information, refer to "Managing Software with yum", available at http://docs.fedoraproject.org/yum/.
