Let's say I have an NSImage that contains some representation other than an
NSBitmapImageRep, and I want to play with the pixel values.
Create your NSBitmapImageRep
Create a NSGraphicsContext from that rep and make it current
Draw your NSImageRep using -draw (or -drawAtPoint: or -drawInRect:) to draw
into the current graphics context.
You now have an NSBitmapImageRep with your image contents.
Thanks!
