Is it possible to take a CGLayer and turn it into a bitmap representation?
Create a CGBitmapContext and draw you layer into it.
Also, is it possible to grab a CGRect "subset" of a CGLayer and append that to a new CGLayer, so that it isn't necessary to recalculate the entirety of a new CGLayer?
CGContextRef ctxt = CGLayerGetContext(mySecondLayer); CGContextClipToRect(ctxt, …) CGContextDrawLayerInRect(ctxt, myFirstLayer, …);
Thanks, Alex
