NetLogo: How to make sure background image dimensions fit a world size?

Question

This might be really basic but is there a clear rule on how to choose world size or on the other hand image dimensions without having so many unclear patches with colors mixed with neighbor patches?

For example this is with world size : 32 * 32

This is for world size 60 * 60 Patch

And finally world size 70 * 60 which works best

Answer 1

Looks like your math was off by one. Suppose min-pxcor and min-pycor are 0 and max-pxcor and max-pycor are 59. Then that's a 60x60 world, not a 59x59 world, because the patch coordinates range from 0 to 59, not 1 to 59.
