2021-10-26 | graphics: Replace RMD160 checksums with BLAKE2s checksums | nia | 1 | -2/+2 | |
All checksums have been double-checked against existing RMD160 and SHA512 hashes | |||||
2021-10-07 | graphics: Remove SHA1 hashes for distfiles | nia | 1 | -2/+1 | |
2015-11-03 | Add SHA512 digests for distfiles for graphics category | agc | 1 | -1/+2 | |
Problems found with existing digests: Package fotoxx distfile fotoxx-14.03.1.tar.gz ac2033f87de2c23941261f7c50160cddf872c110 [recorded] 118e98a8cc0414676b3c4d37b8df407c28a1407c [calculated] Package ploticus-examples distfile ploticus-2.00/plnode200.tar.gz 34274a03d0c41fae5690633663e3d4114b9d7a6d [recorded] da39a3ee5e6b4b0d3255bfef95601890afd80709 [calculated] Problems found locating distfiles: Package AfterShotPro: missing distfile AfterShotPro-1.1.0.30/AfterShotPro_i386.deb Package pgraf: missing distfile pgraf-20010131.tar.gz Package qvplay: missing distfile qvplay-0.95.tar.gz Otherwise, existing SHA1 digests verified and found to be the same on the machine holding the existing distfiles (morden). All existing SHA1 digests retained for now as an audit trail. | |||||
2012-12-20 | Consistently use void. | joerg | 1 | -2/+3 | |
2005-12-30 | stdout can not be used to initialise a global variable.. Move it from | joerg | 1 | -3/+8 | |
global scope to static scope in encoder.c / decoder.c and initialise it from main. Fix a nice side-effect from a macro, which is not a macro in DragonFly: if feof(tablefile) does not parse correctly. | |||||

This software package contains an implementation of JPEG-LS, the emerging lossless/near-lossless compression standard for continuous-tone images being developed by ISO/IEC JTC1/SC29/WG1 (draft document FCD14495 as of November 1997). The names of the executables in the software package derive from the acronym LOCO, as the core of the new standard is based on the LOCO-I algorithm (LOw COmplexity LOssless COmpression for Images) developed at Hewlett-Packard Laboratories (reference: M. Weinberger, G. Seroussi, G. Sapiro, "LOCO-I: A Low Complexity, Context-Based, Lossless Image Compression Algorithm," Proc. IEEE Data Compression Conference, Snowbird, Utah, March-April 1996). The term "near-lossless compression" refers to a lossy algorithm for which each decompressed image sample differs from the corresponding original image sample by not more than a pre-specified value, the (usually small) "loss." Lossless compression corresponds to loss=0. Even though the term "continuous-tone image" refers in principle to any image whose components have more than one bit per sample, palletized images may require a reordering of the color palette for best compression results using LOCO-I on the array of color indices. This functionality is not implemented in the present software, although it is supported by the new standard, and is easy enough to implement with the tools given. Notice, however, that LOCO-I and JPEG-LS were not designed, and might not give optimal performance, for images that have been palletized through dithering. |
