DRAWING

I have a problem that maybe someone could help me with. I have two GWorlds with graphics in them... what I need to do is copy a portion of one GWorld into the other one and have them blend together, like how Photoshop has layers.

I tried using the _blend copy mode with copybits but that produces weird effects. Does anyone know of a simple way to do it or will it be a long and complicated procedure?

Try _addMin (I thinks that's the right constant), it might give you the effect you want.
