NSBitmapImageRep is basically a wrapper around NSDrawBitmap, so it's
probably better to use the class. You would use this class if you wanted
to save/load (mostly custom) images to/from the disk. 

Most likely if you just want to read an image from the disk and display
it in a view, you use NSImage (which encapuslates NSBitmapImageRep and
other representations). See

-[NSImage compositeToPoint:operation:]

to do this.
