In addition, JBIG-KIT\nprovides ready-to-use compression and decompression programs with a\nsimple command line interface (similar to the converters found in Jef\nPoskanzer's PBM graphics file conversion package).\n\nNew in version 2.0 is an additional 'lightweight' version of the jbig\nlibrary, named jbig85. This implements only the T.85 profile of the\nfull standard in the ITU-T recommendation, but is far smaller \nand uses much less memory while encoding. See the homepage for more\ndetails: http://www.cl.cam.ac.uk/~mgk25/jbigkit/\n\nJBIG-KIT implements the specification\n\n  International Standard ISO/IEC 11544:1993 and ITU-T Recommendation\n  T.82(1993), \"Information technology - Coded representation of picture\n  and audio information - progressive bi-level image compression\",\n  <http://www.itu.ch/itudoc/itu-t/rec/t/t82_23822.html>,\n\nwhich is commonly referred to as the \"JBIG standard\". JBIG (Joint\nBi-level Image experts Group) is the committee which developed this\ninternational standard for the lossless compression of images using\narithmetic coding. Like the well-known compression algorithms JPEG and\nMPEG, also JBIG has been developed and published by the International\nOrganization for Standardization (ISO) and the International\nTelecommunication Union (ITU) (see also <http://www.iso.ch/> and\n<http://www.itu.ch/>).\n","package_architecture":"amd64","stem":"jbigkit","readme":null,"dependencies":[],"reverse_dependencies":{"count":7,"url":"/packages/data/5c/5c63c1cb1af80ecbf63b7b77cbb0aacf6109e7fc4cba6d88af21279a68d180e1.json"},"categories":["graphics"],"flavors":[],"only_for_architectures":[],"not_for_architectures":[]}}
