If anyone has a more elegant way to do this, I'd love to hear
it. I had a similar need using JDK 1.1, and created an
image filter which, given an existing image, produces a
new image with all pixels of a certain color made transparent.
I've attached it here. It can be used with the code:
newImage = Toolkit.getDefaultToolkit().createImage(new FilteredImageSource (
oldImage.getSource(), new BluescreenImageFilter())
);
Hope this helps
