how to make it in order to be determined, such as, 1 pixel, 2 pixel, etc. So, it's not too large or too small, example, you're splitting up a huge path, and you want the distance to each other are 3 pixels.

I made a mistake, i should union it first then divide it.

I'm making a world map for game, i try to union some small region with a 20x20 pixel circle. and then this happens...
