Hello! I am looking for some help defining requirements for a perforated panel pattern from an image. I have a script that creates circles of different sizes from the dark and white values of my base image but am trying to define a minimum and maximum radius for the circles as well as set increments by which these circles can increase.

Example: the smallest circles must have a radius of 1mm and the largest circles must have a radius of 5mm. All circles in the pattern must have a radius that increases by 1mm. Therefore the final output would have circles with radiuses that are only 1mm, 2mm, 3mm, 4mm and 5mm.

Thank you in advance for your help!!

Sincerely a very desperate and confused grasshopper user.
