uiscrollview

Hi,

I have an image in an UIScrollView, that can be scrolled and zoomed.

When the user presses a button, I want the code to create an image from whatever part of the UIScrollView is inside an area I specify with a CGRect.

I've seen code to crop UIImages, but I can't adapt it to do the same for a view, because it uses CGContextDrawImage.

Any thoughts?

Cheers, Andre
