Message-ID: <1990Dec4.174144@defoe.enet.dec.com> Date: 4 Dec 90 17:45:17 GMT Sender: newsdaemon@shlump.nac.dec.com Reply-To: jamie@defoe.enet.dec.com () Organization: Digital Equipment Corporation, Landover MD Lines: 14 Something that's probably been covered before, but here goes... sorry if this is just so much repetition... I want to step through the entire colour range, from darkest ($000) to lightest ($777). Does anyone have a routine (preferably assembler, but I'd be happy with anything!) that does this ? Alternatively, does anyone have any suggestions as to how this can be calculated short of building up a table by hand ? Cheers, Jamie.
