I would be very interested in hearing from people who use the run-length code technique for compressing images. In particular, what external (disk) format do you use? At the moment, we are using images of 256 by 256 with 256 colours, so each run nicely fits into 2 bytes: ----------------------- | colour | length - 1 | ----------------------- But what do you do with bigger images? I guess you could just use two of the above runs, or you could use two bytes for length, one for colour e.t.c. How do you do it? (Is there an agreed standard on this?) Any info appreciated, Mike. ------------------------------------------------------------------------------ Mike Parsons UUCP: ..{cfg,edcaad,mcvax,kcl-cs}!ukc!msp msp@ukc.UUCP Mail: Computing Laboratory, University of Kent, Canterbury, Kent, England CT2 7NF
