"Break apart" path into multiple paths

[Dalton Spillman]

I'm working on a vector eraser tool for an app, and I have most of it working by performing a difference operation between the previously-drawn paths and the eraser's path.

I now need to take the path created by the difference operation and break it up into multiple paths based on areas that are separate from one another.

I have tried doing this by starting a new path at each Move verb, but that produces incorrect looking results when erasing the inside of a path: https://youtu.be/aNS8-WW1ZzM

Is there something built-in that will do this for me? Or do you have any ideas on how to do this?

Thank you 🙂

I figured out how to do this by drawing the broken-up paths and comparing the pixels... the algorithm is a little complicated, but it can be done that way.
