JBIG2 in het kort
JBIG2
JBIG and JBIG2 belong to the branch of imaging standards aimed at scanned monochrome or mostly bitonal content rather than rich photographic colour imaging.
J2K in het kort
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
