NSImage -> 1-bit NSBitmapImageRep

Subject: NSImage -> 1-bit NSBitmapImageRep

I've got an NSImage with black and white data in it. I'd like to copy the black and white contents to a 1-bit-per-pixel NSBitmapImageRep.

What's the best way to do this?

I need 1-bit-per-pixel data, rowbytes and a rect so I can pass them into a library.

I've searched the archives and only found solutions for NSBitmapImageRep -> NSImage, but I need the other direction.

I've done this with GWorlds and QuickDraw, but I need a Cocoa solution.

Thank you,
  Sanford
