我可以为笔画添加边框吗？ [英] Can I add a border to a stroke?

问题描述

我知道有些奇怪，但是我使用了非常粗的线条笔划（抚摸一条路径）来绘制弧形段形状。现在客户想要一个围绕'形状'的边框。我的直接想法是通过在它后面画一个稍宽的黑色笔划来伪造它。



然而，我很好奇。是否有正确的方法为行/笔划添加边框？

Somewhat bizarre I know, but I used a very thick line stroke (stroking a path) to draw an arc segment 'shape'. Now the client wants a border around the 'shape'. My immediate thought was to fake it by drawing a slightly wider black stroke behind it.

However, I'm curious. Is there a 'proper' way to add a border to a line/stroke?

推荐答案

您可以尝试这样做。此代码将为您提供行程的矩形边框。

You can try like this. This code will give you rectangular border to stroke.
