Hi I am trying to count the number of black pixels in an image and wondering how this would be done? I am actually trying to count the number of pixels selected by a magic wand selection!
I don’t mean an area of pixels, but an exact amount, for example if my picture was a white background with a black stick man on it, I would want to know the exact number of black pixels, not the number of pixels in the rectangular/square selection box around him…
It would be so great if somebody would help with this, I need to know how to do it for a project I am doing on Data Images, and it is necessary to do this to get an accurate Data-Ink ratio! Thanks alot Beforehand to anybody who answers this!
