Yeah, If you look further down in the documentation, you'll see that there IS
no setImage: NSImage. I've been through this with Apple. Officially, this is a
bug IN THE DOCUMENTATION. Any setImage: NSImage method that exists is
undocumented and may be taken away.
I use this:
CGImageRef nsImageToCGImage(NSImage* image)
{
NSData * imgData = [image TIFFRepresentation];
CGImageRef imgRef = 0;
if(imgData)
{
CGImageSourceRef imageSource =
CGImageSourceCreateWithData((CFDataRef)imgData, NULL);
imgRef = CGImageSourceCreateImageAtIndex(imageSource, 0, NULL);
}
return imgRef;
}
