在ASP.NET中的两点之间绘制箭头

Question

我在ASP.NET中动态生成图像。如何在下面的代码段中绘制箭头而不是线条。我找不到任何API。

Bitmap image = new Bitmap(640, 480);
Graphics graphics = Graphics.FromImage(image);
.
.
graphics.DrawLine(new Pen(Color.Red), lPoint, rPoint);

Answer 1

Bitmap image = new Bitmap(640, 480);
Graphics graphics = Graphics.FromImage(image);
Pen p = new Pen(Color.Red, 10);
p.EndCap = LineCap.ArrowAnchor;
graphics.DrawLine(p, lPoint, rPoint);

请参阅LineCap Enumeration MSDN
