For example, I have a 200*200 image, and I would like to know the color code in position 50, 50. How can I do so ? Thank you. (I am using Objective C and iPhone SDK.)
A:
This looks like a duplicate of How to get pixel data from a UIImage (Cocoa Touch) or CGImage (Core Graphics)? If not, they seem closely related.
