Someone told me that one of the new paint packages - either Photon Paint or Express paint - uses copper lists to do some of the fancy split screen stuff. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Carolyn Scheppner -- CATS >>Commodore Amiga Technical Support<< UUCP ...{allegra,ihnp4,rutgers}!cbmvax!carolyn PHONE 215-431-9180 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Photon Paint provides a "Fast Menu" for selection and adjustment of a HAM color palette. The Fast Menu is a short window as wide as the screen which can be moved vertically. The program appears to change the hardware color table (via the copper) just before and just after the scanlines the Fast Menu is sitting on. I imagine this is to allow the program a fixed set of base HAM colors to work its color palette magic. -scott
