I am using CGImageSourceCreateImageAtIndex and related functions. But I am still unclear which function actually takes the time. Maybe it is only when I create the CALayer like this? CALayer * imgLayer = [CALayer layer]; imgLayer.contents = nsimage; > > Why not? Dispatch queues are always available. (The main thread is simply a > special queue.)
