Re: Compositing to custom view in Cocoa

But why would you do this when you could just change the format of 
your graphic to tiff and replace the white background with 
transparency? This is relatively simple to do with Photoshop or Gimp, 
etc. With Cocoa it's just one line to composite the section of the 
image containing your character, retaining the transparency. If your 
view is filled with a green background and you composite 
(NSCompositeSourceOver) the character image over top this background, 
only the text part will show up with the green background showing 
through.
