C#实现图形区域组合操作的方法

本文实例讲述了C#实现图形区域组合操作的方法。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;
namespace advanced_drawing
{
 public partial class Form17 : Form
 {
   public Form17()
   {
     InitializeComponent();
   }
   private void Form17_Paint(object sender, PaintEventArgs e)
   {
     Rectangle regionRect = new Rectangle(20, 20, 100, 100);
     e.Graphics.DrawRectangle(Pens.Black, regionRect);
     RectangleF unionRect = new RectangleF(90, 30, 100, 100);
     e.Graphics.DrawRectangle(Pens.Red, Rectangle.Round(unionRect));
     Region myRegion = new Region(regionRect);
     //myRegion.Union(unionRect);
     //myRegion.Intersect(unionRect);
     //myRegion.Exclude(unionRect);
     //myRegion.Complement(unionRect);
     myRegion.Xor(unionRect);
     SolidBrush myBrush = new SolidBrush(Color.Blue);
     e.Graphics.FillRegion(myBrush, myRegion);
   }
 }
}

希望本文所述对大家的C#程序设计有所帮助。
