Get pixel data from an image?
I'm trying to make a photomosaic generator for OSX. What I need is to be able to get direct bitmap/pixel data from images (so I can determine the average colour of a mosaic tile), but NSImage seems too high level for this. Any help please? The Apple documentation about drawing looks huge and has lots of variants (Cocoa, Quartz, OpenGL)… I'd prefer Cocoa here.

Get your image as a NSBitmapImageRep then use colorAtX:y: on it.
