My humble experience shows that 

-[NSImage compositeToPoint:operation:]

does not respect scaling and rotation of the affine transformation
(which is applied to the drawing context, if I get it right).
It respects only translation.

If you want to scale the image, you need NSImageRep:

    NSAffineTransform * transform = ...; // get the transform somehow

    [transform concat];

    // Get NSImageRep of image
    NSImageRep * rep = [image bestRepresentationForDevice: nil];

    [rep drawAtPoint: NSZeroPoint];
