| | | | | | | | --SNIP-- (...) Good thinking. Since the old colours were derived from the EGA colour palette I reckon the dithers would have to be derived from it too. Otherwise you could end up with some very different blends. I like your signature ;) Tim (15 years ago, 12-Feb-10, to lugnet.cad.mlcad)

| | | | | | | | (...) Also I am thinking that we have to use the original color values for the color 0 - 15 to build the blended colors. Otherwise we get other colors.

| | | | | | (...) I think Travis' wording may be confusing. Don't use "the old dither algorithm". MLCad 3.30 draws colors 256-511 as *solid* colors. That's better than using the stippling algorithm from previous MLCad versions. (No new/current software stipples (...) (15 years ago, 10-Feb-10, to lugnet.cad.mlcad)

I've been surprised by some of this discussion of dithered colors, because when Foundry was created (not by me), it was done as a "clean room" project, based entirely off of specs, so it's the closest thing out there to a reference parser, and (...)
