Thanks, that is what I was hoping. I have a ChromaKey filter that works very
well and was hoping to keep it. I created one using CIColorCube, but it was
not as good, and I had issues scaling any applied background image to fit
properly, and being able to tweak parameters in real-time.
Along this line, I still don’t know how to scale a CIFilter effect when
applied to a layer, specifically an AVCapturePreviewLayer. It always
applies the filter effect at the scale of the containing view, not the size
of the layer. Any insights here would be appreciated.
