Drawing NSImage in grayscale

Subject: Drawing NSImage in grayscale

Are there any easy techniques (e.g. compositing operations, perhaps in several passes) for drawing a color NSImage instantiated from a tiff file in grayscale?

The only way I can think of would be to create an NSBitmapImageRep with one data plane and draw into that.

Thanks for any ideas!
