C#画笔Pen使用路径绘制图形的方法
本文实例讲述了C#画笔Pen使用路径绘制图形的方法。分享给大家供大家参考。具体实现方法如下：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
usingSystem.Drawing.Drawing2D;
namespaceWindowsApplication2
{
publicpartialclassForm10:Form
{
publicForm10()
{
InitializeComponent();
}
GraphicsPathget(Rectanglerect,intradius)
{
intdiameter=2*radius;
Rectanglearcrect=newRectangle(rect.Location,newSize(diameter,diameter));
GraphicsPathpath=newGraphicsPath();
path.AddArc(arcrect,180,90);
arcrect.X=rect.Right-diameter;
path.AddArc(arcrect,270,90);
arcrect.Y=rect.Bottom-diameter;
path.AddArc(arcrect,0,90);
arcrect.X=rect.Left;
path.AddArc(arcrect,90,90);
path.CloseFigure();
returnpath;
}
privatevoidbutton1_Click(objectsender,EventArgse)
{
Graphicsg=this.CreateGraphics();
intwidth=this.ClientRectangle.Width;
intheight=this.ClientRectangle.Height;
Rectanglerect=newRectangle(10,10,width-20,height-20);
GraphicsPathpath=get(rect,width/10);
g.FillPath(Brushes.Red,path);
g.DrawPath(Pens.Yellow,path);
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
