Circle Diameters and Image Sampler

Hello I would like to be able to use the image sampler in GH to create an image of circles. However I would like to only use three circle sizes, 1/8, 3/16" and 1/4" diameter circles.

How can I tell the image sample to apply these three diameter circles in the image, so that the dark areas get the largest circles (1/4") and the whiter areas get 1/8" diameter circle?

Basically I would like to make the same image below - put only using three set diameters. How can I do that?

Thanks!

If you want to put three values, you must put an image having at least 3 tones, ie, not valid having only black and white.

Nice! That looks like something I am looking for. I did try this one as well. It has a gray tone, white and black in the image. The image was photoshopped from an Auto CAD drawing to have tones.

If I was to use this image - does your definition allow me to set the three diameters independently So I could have the black be the largest diameter and the white be the smallest?

Also setting a minimum hole spacing (due to CNC milled material) is that possible (or is that only in the x,y input on your planer srf) or my x,y of my grid spacing?
