问题是什么是最好的办法它使用python / PIL ...

Question is what is the best way to do it using python/PIL...

推荐答案

我想你需要一些泛洪算法（比如广度优先）遍历）你停止探索不同于黑色的像素。

I suppose you would need some flood-fill algorithm (such as breadth-first-traversal) in which you stop exploring pixels with different color than black.

维基百科对动画和伪代码有很好的解释

Wikipedia has an excellent explanation with animations and pseudo-code
