I am looking for the coding scheme for FAX machine. How a picture or text is represented in FAX coding format. Any input will be appreciated. ============================================================================= KAM KEUNG LAI SAN JOSE STATE UNIVERSITY, CALIFORNIA ************** BITNET: TGTL003@CCS.CSUSCC.CALSTATE.EDU *************** =============================================================================

The FAX formats are documented in CCITT Recommendation T.4 and T.6 (Group 3 and Group 4, respectively) of Fascicle VII.3. Basically, FAX formats use run- length encoding with variable-length bit fields. Horrible to understand, and even worse to parse... Currently, I am trying to write a converter module which reads/writes G3/G4 FAX files, and produces my standard bitmap format. -- Juergen "Gandalf" Wagner, gandalf@csli.stanford.edu Center for the Study of Language and Information (CSLI), Stanford CA
