如何旋转GraphicsPath？ [英] How to rotate a GraphicsPath?

问题描述

如何将图形路径旋转到给定角度？

How can I rotate a graphicspath to a given angle?

PointF[] points = new PointF[]
{
new PointF(0,10),new PointF(220,10),
new PointF(220,0),new PointF(270,12.5f),
new PointF(220,25),new PointF(220,15),
new PointF(0,15)
};
GraphicsPath path = new GraphicsPath();
for (int i = 0; i < 6; i++)
{
    path.AddLine(points[i], points[i + 1]);
}
path.AddLine(points[6], points[0]);

路径返回箭头路径。

The path returns an arrow path.

推荐答案

不要旋转路径，旋转坐标系。

Don't rotate path, rotate coordinate system.
