在PathGeometry内部进行命中测试 [英] Hit Testing inside of PathGeometry

问题描述

如果我将图像剪切到PathGeometry上，如何将该PathGeometry内的特定点命中另一个具有相似属性的对象.基本上，我想检查Image1或Image2的一部分是否彼此靠近，以及是否将它们组合成一个边框对象.如果我能弄清楚如何通过命中测试来启动某个功能或其他东西，那么我可以自己将它们组合起来.

Image1

If I clip an image to a PathGeometry how can I hittest a specific spot inside that PathGeometry to another object with similiar properties. Basically I want to check if a part of Image1 or Image2 go near each other and if they do combine them into one border object. If I could figure out how to get the hit test to launch a function or something I could then combine them myself.
