To get this to work I had to flip the context vertically, otherwise the context you’re using is upside down.

I added this at line 81:
// Flip context
CGContextTranslateCTM(context, 0, height);
CGContextScaleCTM(context, 1.0, -1.0);

I think you may have never noticed it because your shapes are diamond shaped so it doesn’t matter if they’re flipped. I was using a PNG of a duck…and was having all sorts of problems!

Let me know if I’m mistaken.
