while i know that here are already other people have photoshop style copymodes for rgb picture/video channels available, i´d like to extend my own and write things from scratch.
i could not find any useful sources on the net from where i could start implemting math operations for RGB numbers/lists. though many of the copymodes are pretty easy and i could just find them by trial and error, i would (this time) prefer to do thing "right", reproducing the right effect for the right terminology.
the adobe and quicktime development docs are also everything else but useful. does anyone know where to find such descriptions for calculating RGB stuff?
