Summary: A reference to .img spec Message-ID: <9679@chinet.chi.il.us> Date: 27 Sep 89 02:57:36 GMT References: <672@ncs.dnd.ca> Organization: Chinet - Chicago, Ill. Lines: 7 STWorld has a description of the GEM .img format in the July 1989 issue. It contains some slight ambiguities, so I'd start out reading files for a while before writing them (lest my .img files were unreadable). But basically the organization is that each bitplane is written out explicitly in turn (with some fairly simple compression). Steve J.
