I'd say that's exactly what you want - NSBitmapImageRep. You can use its setPixelAtX:y: method to set each pixel individually, provided that ultra-high performance isn't a key requirement. The rep can be drawn directly into a view or wrapped with an NSImage and drawn using that.

Look up that class in the docs and it also links to other relevant docs and samples.
