I'm working with multiple programs including ArtRage.
If I have scanned artwork on a white background, I know I can import it as a Tracing Image, and then Convert Tracing Image To Paint On This Layer to make it into a layer.
Then I can switch it to Multiply Mode, and that seems to work -- but what I really want to do is eradicate the white background on the newly imported image. I've tried adding a new transparent layer to merge with the scanned artwork layer, but the white background stubbornly comes back.
Is there some way I can get around this? I like to avoid using any funky layer blending modes due to the extra CPU load required to perform display updates, and I also want to be able to merge my linework layers(to save memory and CPU) with other layers and not have the white background contaminate/interfere with them.
