By making the NSBitMapRepresentation yourself, creating a context for it, drawing to that. If you make it yourself using the long-winded but complete initializer, you have total control. Any of the other ‘convenience’ methods do various things that you can’t see, are poorly documented, and give unexpected results. Even when they work today their implementations change and one day might do something else, suddenly breaking your code. I’ve certainly had that happen when Retina screen came out for example, and had to go back and do it using the long initializer so I got what I asked for. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
