/* * Copyright Yves Dorfsman 1999-2011. * * cals2tiff: is used to convert .cal files (US NAVY CALS raster file Type 1, * a.k.a. MIL-PRF-28002) into .tiff files (baseline TIFF bilevel images). * * calsinfo: is used to show the content of the header of CALS files. * * CALS type 1 only supports compressed data, and only using the CCITT * group 4 algorithm (T6). Tiff revision 6.0 can support this same * compression scheme (among others) for bilevel raster files, so * there is no need to change the data to convert from one format to the * other ; only the header is re-written. * * * Major bugs have been recently (2009/01) reported, but have now been fixed. * Do not use any version prior to v2.00, although the TIFF files they created * were usable most of the time, they were not compliant with the standard, * as reported by tiffinfo. * * The orientation of the converted CALS images should be correct now. However, * note that most free software do not take tiff orientation into account. * "gthumb" is one * of the few which does display tiff images correctly. * * * * * The current version is v2.0, you can download bz2, gz, and zip archives * (or bz2, gz, and zip for the latest version). * * You can access individual files and other versions directly from * the Mercurial repository. * * * */
