Hi,
I would use the 'getHistogram' macro function...
getHistogram(values, counts, nBins[, histMin, histMax])
Then the number of zero pixels is given by 'counts[0]'.
Greg.

Greetings:
I've written a macro to help determine the area of injury to turfgrass (putting greens)....the macro works great except for the very end....what I need to do is to get the number of pixels in an image corresponding to count 0 of 256 (black)....I can get the total number of pixels in the image but need the value for count 0 to create a percentage of black to all other pixels.....how do I get that value? Any help is greatly appreciated....thank you.
