Hi, I just came across this thread, and I solved a similar problem earlier.
This is the code I ended up using:
NSImage *oldImage;
CALayer *layer;
CGImageRef newImage = [[[oldImage representations] objectAtIndex:0]
CGImage];
[layer setContents:(id)newImage];
It may be too late for this specific s
Hi Matt
I'm not involved in the discussion. I just wanted to thank you for the

You can do this to get a CGImageRef directly. (written in Mail, no

Hi,
I'm trying to draw an NSImage (a PNG) in a CALayer. The goal is to
create a method that allows me to pass an NSImage as an argument to
create a layer-hosting view. I have:

imageLayer=[CALayer
