- Isn't this just as simple as c = pi * d
-
- If your short axis display minimum resolution is 600 pixels then the
- maximum diameter of a circle to be contained in it is also 600 pixels.
- Then the number of pixels in the circumference should be (pi * 600) pixels and
- the minumum radius would be of course 400 pixels.
