I'm wanting to create a CGImageRef from a quartz based CGContextRef, so that I can feed a CALayer with it. Is there a preferred way of doing this? I did think of creating a CGLayer, drawing into it's context, and then creating a CGImageRef via a CIContext createCGImage:inRect: call - is that recommended? Or is there a simpler way?

If you have a bitmap context, you can just call CGBitmapContextCopyImage() to get an image you can use from it. Can you explain your situation a bit more? -- David Duncan Apple DTS Animation and Printing email@hidden
