How can I 'binarize' an NSImage (or an NSBitmapImageRep if that's a better approach)?
I understand the concept of thresholding an image to turn it into a 1-bit image. I don't know, though, whether this are already methods/functions to do this to an NSImage, or whether I must manually iterate over the pixels, and deal with each pixel.
There are Core Image filters designed for this; check out the answer to this question .
