UIImage crop and rotate based on other uiview

[amiton]

Hi,
i have a UIViewController that holds 2 subviews:
1. UIImageView (the picture i want to crop) which is displayed full screen (320*480), the internal UIImage is actually 1200*1600.
2. UIImageView that the user can drag and rotate on screen (area selection).

After the user finishes rotating and moving the second UIImageView (using touches) i want to crop the selected area (resized and rotated) from the first UIImageView.

Please help (link / code / guide...).


Thanks,
Amit On
