如何使用Graphics2D平滑手绘线条(how to smooth a hand-drawn line with Graphics2D)

我已经使用这段代码在Java和Graphics2D中实现了一个徒手绘图工具。 所以我有一个由很多点组成的Path2D。 有没有算法来平滑这条线？ 我不是指抗锯齿，我的意思是将路径转换为贝塞尔曲线的路径。 像这样的东西，但有一个Path2D作为输入。 我认为这是一个反复出现的问题，但我真的找不到有用的东西。

I've used this code to implement a freehand drawing tool in Java and Graphics2D. So I have a Path2D made up of a lot points. Is there an algorithm to smooth this line? I don't mean anti-aliasing, I mean something like converting the path to a path of bezier curves. Something like this, but with a Path2D as input. I would think this a recurring problem but I couldn't really find something useful.

编辑：因为我现在知道这个问题的确切术语（曲线拟合）我可以更好地谷歌它也发现这篇文章： Java曲线拟合库

I've found what I needed at: http://javagraphics.blogspot.com/2010/06/shapes-implementing-freehand-pencil.html

Edit: and since I now know the exact term for this problem (curve fitting) I can google it better and also found this post: Java curve fitting library
