本文介绍了在绘图中如何使用LineCap来改变线条端点的样式。LineCap支持三种类型：CAP_BUTT、CAP_ROUND和CAP_SQUARE。通过示例代码展示了如何在不同类型的LineCap之间进行切换并应用于实际线条绘制。

LineCap 指定了开放路径端点的形状。有三种不同的类型：CAP_BUTT, CAP_ROUND和CAP_SQUARE。

下面代码显示了三种不同的LineCap类型。

private void LineCap()
{
 Color blackColor = new Color(0x000000);
 Color whiteColor = new Color(0xffffff);
 graphics2D.Reset();
 graphics2D.Clear(Color.White);
 
 Pen pen = new Pen(blackColor, 20, Pen.CapButt, Pen.JoinMiter);
 graphics2D.DrawLine(pen, 40, 60, 140, 60);
 pen = new Pen(whiteColor, 1);
 graphics2D.DrawLine(pen, 40, 60, 140, 60);
 pen = new Pen(blackColor, 20, Pen.CapRound, Pen.JoinMiter);
 graphics2D.DrawLine(pen, 40, 100, 140, 100);
 pen = new Pen(whiteColor, 1);
 graphics2D.DrawLine(pen, 40, 100, 140, 100);
 
 pen = new Pen(blackColor, 20, Pen.CapSquare, Pen.JoinMiter);
 graphics2D.DrawLine(pen, 40, 140, 140, 140);
 pen = new Pen(whiteColor, 1);
 graphics2D.DrawLine(pen, 40, 140, 140, 140);
}
