Dear labmembers:
I have a feature of hexagonal array of holes in polystyrene film such as the attached image.
I would like to get the diameter of each hole and hole to hole spacing out of the image to examine the spatial uniformity.
Does anyone know any software that may help?

Thank you in advance.
