Hi,
if you’re on Leopard only, you can use the new screen capturing APIs
to capture the screen area you need (look for the SonOfGrab sample
code). I’d say magnifying the captured pixels is left to you. Some
carefully chosen scale factor during drawing together with disabled
anti-aliasing might work.

Hi guys.
I'm currently working on my own custom color picker, and it's all
going well. However, I need to replicate the magnifying function
found in a NSColorPanel. I think I've figured out how to capture
mouse-events anywhere on the screen, but I don't know how I would go
about to "magnify" what's beneath the cursor. Any help is greatly
appreciated.
Kind regards,
Tim
