grayscale strokes can become transparent becuz they can have color added or they can be used to erase (take color away). I'm assuming the PNG means an image 'completed' in PNG format and used in another image--therefore how it works is different (of course)...I'm thinking this out loud to help me clarify it in my head

to be able to use vector and bitmap in the same layer is great...psp 7 can't do that

really helpful explanation--and I really like your leaf strokes
