IPhone Goal C: How to get the pixel color of the affected point on a UIImageView?

Question

iPhone Goal C: How do I get the pixel color of an affected point on a UIImageView , even if the parent UIView or itself rotates with the CGAffineTransformMakeRotation function?

Will the UITouch view property still correctly return the correct pixel of the affected point, even if I scale and rotate the UIView / UIImageView ?

Thanks so much for reading

edited: thanks for the answer and comments, but unfortunately I still don’t know how to get the X, Y point of the scaled / rotated image from the touch event, and then extract the color from it. Can anybody help?

A quick google search showed some promising results:

• Retrieving Pixel Data from a CGImage Object
• stack overflow
• What color is my pixel?
