Err, and the color-averaging I always tend to forget about. The DCON selects either just a single color component for a pixel (color mode) or combines red, green, and blue into a per-pixel value (monochrome mode). In early hw versions this could be toggled separately from the anti-aliasing, while in MP hardware those two were combined IIUC. - Bert - _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
