在Java 2D中裁剪一般路径

Question

I have java general path with random points. I want to crop one side of it and get straight line.

How to make it?

Answer 1

1. Create an Area based on the 1st GeneralPath based on this constructor . I'll call it mainArea .
2. Create a Rectangle2D based on the line, covering the area to the left of it as well. I'll call it lineArea .
3. Call Area.subtract(Area) using mainArea.subtract(lineArea);
