A need I have when I bring in a reference pic is to be able to set a particular colour to tranparent, the way you would with a transparent gif.
Kinda like a 'bluescreen mode'.
Here's an example... Say I've designed something in CorelDraw, and want to bring it in so that what's white in the scamp is transparent in ArtRage.
Currently, I have to actually use the eraser tool to remove the white bits. (This is an artefact from the fact that I'm using a hack to create a layer.... I'm converting trace image to paint, and so it sees the white as paint.)
Any chance of a function like this? Something like an eyedropper with a dialogue that says, 'make this colour transparent on this layer'.
