Straight from the docs:
NSAffineTransform* t = [NSAffineTransform transform];
[t translateXBy: 0.0 yBy: [im size].height];
[t scaleXBy: 1.0 yBy: -1.0];
[NSGraphicsContext saveGraphicsState];
[t concat];
// draw here
[NSGraphicsContext restoreGraphicsState];
More that, without seeing your code, is hard to say. m.
