How would one go about figuring out the mathematical area (xxx units squared) of a closed vector path?


Does it have to be mathematical?  How much precision do you need?

Note: These paths will not be simple little boxes or circles. Think complex paths--composed of mulitple line segments and arc segments (both convex and concave).


Here's a really awful brute force method:

1. let Quartz (or other graphics API) render your path at (pretty) high resolution 2. count bits

In fact, with Quartz doing partial-coverage, you might even be able to get away with a bit less resolution..
