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:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Drawing.Drawing2D; namespace WindowsApplication2 { public partial class Form10 : Form { public Form10() { InitializeComponent(); } GraphicsPath get(Rectangle rect, int radius) { int diameter = 2 * radius; Rectangle arcrect = new Rectangle(rect.Location, new Size(diameter, diameter)); GraphicsPath path = new GraphicsPath(); 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(); return path; } private void button1_Click(object sender, EventArgs e) { Graphics g = this.CreateGraphics(); int width = this.ClientRectangle.Width; int height = this.ClientRectangle.Height; Rectangle rect = new Rectangle(10, 10, width - 20, height - 20); GraphicsPath path = 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。
