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 situation, but maybe someone else can use it. ~ Steven Degutis http://www.degutis.org/ On Thu, Sep 18, 2008 at 4:54 PM, Brad Gibbs <[EMAIL PROTECTED]> wrote: > Hi, > > I'm trying to draw an NSImage (a PNG) in a CALayer.
