Crop Image in specific shape Cocos2d

Question

I have an UIImageView* shape which is in fixed position. Behind that view I have another view which I can move, scale and rotate with gestures. I would like when I finish with customising the view behind the "shape" to press a button crop and crop the image. You can see video here of what exactly I am trying to do.

Answer 1

You can mask one image with another image to get custom shape image. See tutorial to get some idea about masking
