Subpackage Descriptions
single JBIG-KIT implements a highly effective data compression algorithm for bi-level high-resolution images such as fax pages or scanned documents. This is a portable library of compression and decompression functions with a documented interface that can be included into your image or document processing software. Also provided are ready-to-use compression and decompression programs with a simple command line interface (similar to the converters found in Jef Poskanzer's PBM 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", , 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 and ).
