I am producing bitmapped images on a LaserWriter Plus using PostScript, noteably the "image" operator. The image data can get huge, and I would like to do run-length compression. Anybody know how if this is possible using the "image" operator, or any other method in PostScript? Please e-mail responses. Thanx, Marc Johnson Rockefeller Univ. marc%rna@rockefeller.edu (129.85.2.1) rna!marc@rockvax.bitnet ...cmcl2!rna!marc

Sun2PS, which takes Sun format windows and generates PostScript images from them, and the X11 version of xpr. Both use RLL encoding to generate much smaller (e.g. ~30% size) files. Check with a site near you that has Suns or X11, or they can be posted if needed. (BTW I have made an X10 version for anyone who is interested).
