Hello !!

My name is Aldo Ramos and my question is simple:

How can I count the pixels in an image with a color or
B&W scale criteria?

Thank you all very much !!!

You can use the 3D color inspector.

Use Analyze>Histogram or a simple macro like this:

       getRawStatistics(pixelCount);
       print("Pixel count: ", pixelCount);
