As far as i understood, this class is abstract, and its subclasses implement more specific behavior - shadow - semitransparency mapping The idea of is kind of canvas is to modify/filter the final output in rendering pipe.. i.e., for each potential pixel operation like: source -> op -> output it introducing a color mapping stage: source -> op -> mapping -> output So, then for instance you could make a subclass which could turn all colors to be grayscale (disregarding that initial input was in colors). in fact i think this guy took wrong direction. It is much more effective to let the canvas to draw whatever it wants to some backup/temporary surface, and once it done, simply blit + color-map result to destination form using one, single strike. -- Best regards, Igor Stasenko AKA sig.
