Hi, I'm a little shaky in this area, so I beg your pardon.
CALayer has a "contents" property which is a CGImageRef, i.e. a Core Graphic image. CGImages are stored in RAM. CALayer is built on top of OpenGL and uses VRAM to store its bitmap image internally (a texture). Now suppose that I have a CIImage constructed with +imageWithContentsOfURL. The image is loaded (lazily) directly to VRAM. So, If I go the suggested route, and first create a CGImage from CIImage, then assign it to CALayer's contents, I will effectively copy the image from VRAM to RAM and then again back to VRAM, which is slow, memory consuming, and generally unnecessary. Am I correct? If so, is there a way to pass a CIImage directly to CALayer without going beyond VRAM? Thanks!
