That version only works for a ±90° rotation since you're just
swapping the width and height for the rotated image size. A more

Thank you, Steve. Yes, yours works for a 45° rotation whereas mine
clipped.
Jerry,
I'll offer a couple of other alternatives:
1) Use Quartz Composer to do the transformation for you. You should
be able to build a composition with just a few (2?) patches. You can
even bind the parameters for the composition to controls on your UI
using Interface builder.
2) Us

You can't do it without drawing, but the draw

You can't do it without drawing, but the drawing doesn't need to be
onscreen.
Thanks, Graham.

I understand that NSAffineTransform can rotate an image while you're
drawing it. But is there any way to rotate an image and get a new
image? Something like:
NSImage* imageUp = [NSImage imageNamed:@"BaseImage"] ;
NSImage* imageLeft = [image
