[] I've been thinking recently about transferring ST screen-dumps (32K bit-maps, one bit deep in "hires" (monochrome) mode) over the modem (to a VAX running UNIX, to print the graphics on a laser-printer). Since my applications are concerned with B&W line drawings which are mostly white space, it would be very inefficient to send the whole 32K. Also I'd like some compression method to compress it before I ever save it on the ST disk. I guess I could use ARC or some other standard, general purpose compression program. But it seems that an algorithm designed especially for this purpose should beat general ones handily! I am thinking about an algorithm that would compare bytes (or words) VERTICALLY DOWN THE SCREEN, rather than along consecutive RAM. Such an algorithm would find more runs of identical bytes. It should also work for color. Is such a thing available (preferably PD)? Is anybody working on one? Or should I do it myself? - Moshe Braner
