:-) That's a pretty broad question. It works just like drawing *on-screen*, but you create your "canvas" in code, draw to it, then do something with the drawn result.

Start here: http://developer.apple.com/documentation/Cocoa/Conceptual/ CocoaDrawingGuide/index.html

If you need to draw something to an NSImage off-screen, just create your image at the correct size, then -lockFocus on it, do the drawing, -unlockFocus, and you've got a nicely-formed image to do with whatever you want (composite it to an on-screen view, or set it as a button's image, etc.).

  Hope this helps.

Okay.

So, I've never done any "off screen drawing" before and I need some
help with this. To put it bluntly, how do I do it? Or, where do I
start?

Thanks, Alan
