In addition, JBIG-KIT +provides ready-to-use compression and decompression programs with a +simple command line interface (similar to the converters found in Jef +Poskanzer's PBM graphics file conversion package). + +JBIG-KIT implements the specification + + International Standard ISO/IEC 11544:1993 and ITU-T Recommendation + T.82(1993), "Information technology - Coded representation of picture + and audio information - progressive bi-level image compression", + <http://www.itu.ch/itudoc/itu-t/rec/t/t82_23822.html>, + +which is commonly referred to as the "JBIG standard". JBIG (Joint +Bi-level Image experts Group) is the committee which developed this +international standard for the lossless compression of images using +arithmetic coding. Like the well-known compression algorithms JPEG and +MPEG, also JBIG has been developed and published by the International +Organization for Standardization (ISO) and the International +Telecommunication Union (ITU) (see also <http://www.iso.ch/> and +<http://www.itu.ch/>). |
