printing out pixel values to a results table

[Paxton Provitera]

Hi.

I am having the hardest time doing something that should be easy.

I want to print non-zero pixel values out to the results table.

I have 640 by 480 images that will have about 20K non-zero pixel values.
is there an easy way to do this?

thanks a ton!

Hi Paxton

You might find the Log window more accommodating, i.e. the output from:

print(pixel_value, "\n");

Here is a macro that writes non-zero pixel values to the Log window.

   h=getHeight();
   w=getWidth();
   for (y=0; y<h; y++) {
       for (x=0; x<w; x++) {
           value = getPixel(x, y);
           if (value!=0) print(x, y, value);
      }
   }
