Compositing to custom view in Cocoa

Hi everyone. I'm still struggling to find out how to replace colors in an image, before I draw it to the screen.

Basically I have a black and white image, as an image resource in my bundle, and subsequently as an NSImage in my app.

When I draw it in my custom view, I'd like to replace all the 'white' pixels with my current background color, and all the black pixels with a specific fore-ground color.

I've been all through the NSImage and NSView docs, but can't seem to come close to this.

For an example of what I'm doing look at http://www.kmillar.co.uk/mac/ macstuff.html

Thanks in advance everyone.

-Kenny
