Punching holes into IKImageView

I have an IKImageView and would like to create holes, i.e. set alpha to zero in some rectangle. And then save the result in some format. What would be the easiest way to do this? 1. Create a CIFilter and do: myIkImageView.imageCorrection = myHoleFIlter save myIkImageView 2.

I don't mind using private API for this. After all my goal is to make some simple in-house app and it doesn't matter too much if it breaks after some OS X update. I am aware the private API discussion is forbidden here. Thus, if anyone can point me in the right direction, I would appreciate it
