Hi all,

I'm looking for a short bit of Java that will check to see if an image
is binary (result of Adjust->Threshold->Apply) or not. Just checking bit
depth and making sure that pixel values are 0 or 255 is not quite enough
because

ImageStack.getPixels(int n);

returns an array of 0 (background) and -1 (foreground) elements, and I
use raw 0 and -1 values in my logic.

Cheers

Mike
