WPF2D绘制图形方法

我们先看看效果如何：

xaml文件：

<Window x:Class="WPF2D绘制图形方法.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="" Width="" Background="DarkSalmon">
    <Grid Name="Grid1" Height="" Width="">
        <Button Content="一般方式绘制" Height="" HorizontalAlignment="Right" Margin="0,12,329,0" Name="button1" VerticalAlignment="Top" Width="" />
        <Button Content="高性能绘制" Height="" HorizontalAlignment="Left" Margin="141,11,0,0" Name="button2" VerticalAlignment="Top" Width="" />
        <Button Content="图形运算" Height="" HorizontalAlignment="Left" Margin="279,9,0,0" Name="button3" VerticalAlignment="Top" Width="" />
        <Label Content="WPF2D绘制图形展示" Height="" HorizontalAlignment="Left" Margin="99,41,0,0" Name="label1" VerticalAlignment="Top" FontSize="" Width="" />
    </Grid>
</Window>

我们具体看看代码：

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
 
namespace WPF2D绘制图形方法
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.button1.Click += new RoutedEventHandler(button1_Click);
            this.button2.Click += new RoutedEventHandler(button2_Click);
            this.button3.Click += new RoutedEventHandler(button3_Click);
        }
 
        void button1_Click(object sender, RoutedEventArgs e)
        {
            //绘制一个简单的矩形，System.Windows.Shapes 基类
            //http://msdn.microsoft.com/zh-cn/library/vstudio/system.windows.shapes(v=vs.100).aspx
            Rectangle MyRectangle = new Rectangle();
            MyRectangle.Margin = new Thickness(, , , );
            MyRectangle.Width = ;
            MyRectangle.Height = ;
            MyRectangle.Fill = Brushes.BlanchedAlmond;
            MyRectangle.Stroke = Brushes.Blue;
            Grid1.Children.Add(MyRectangle);
        }
        void button2_Click(object sender, RoutedEventArgs e)
        {
            //绘制一个简单的矩形，Geometry 类
            //http://msdn.microsoft.com/zh-cn/library/vstudio/system.windows.media.geometry.aspx
            RectangleGeometry myRectangleGeometry1 = new RectangleGeometry(new Rect(new Size(, )));
            Path myPath1 = new Path();
            myPath1.Margin = new Thickness(, , , );
            myPath1.Stroke = Brushes.Red;
            myPath1.Fill = Brushes.Gold;
            myPath1.StrokeThickness = ;
            myPath1.Data = myRectangleGeometry1;
            Grid1.Children.Add(myPath1);
 
            RectangleGeometry myRectangleGeometry2 = new RectangleGeometry(new Rect(new Size(, )));
            Path myPath2 = new Path();
            myPath2.Margin = new Thickness(, , , );
            myPath2.Stroke = Brushes.Red;
            myPath2.Fill = Brushes.SpringGreen;
            myPath2.StrokeThickness = ;
            myPath2.Data = myRectangleGeometry2;
 
            Grid1.Children.Add(myPath2);
 
        }
        void button3_Click(object sender, RoutedEventArgs e)
        {
            //绘制圆
            EllipseGeometry eg1 = new EllipseGeometry(new Point(, ), , );
            EllipseGeometry eg2 = new EllipseGeometry(new Point(, ), , );
            EllipseGeometry eg3 = new EllipseGeometry(new Point(, ), , );
            EllipseGeometry eg4 = new EllipseGeometry(new Point(, ), , );
 
            //区域进行合并，可以求交集，并集....其它等；
 
            CombinedGeometry cg1 = new CombinedGeometry(GeometryCombineMode.Xor, eg1, eg2);
            CombinedGeometry cg2 = new CombinedGeometry(GeometryCombineMode.Xor, eg3, eg4);
 
            //绘制
            Path myPath = new Path();
            myPath.Margin = new Thickness(, , , );
            myPath.Stroke = Brushes.SeaGreen;
            myPath.Fill = Brushes.Violet;
            myPath.StrokeThickness = ;
            myPath.Data = cg1;
            Grid1.Children.Add(myPath);
 
            Path myPath1 = new Path();
            myPath1.Margin = new Thickness(, , , );
            myPath1.Stroke = Brushes.SeaGreen;
            myPath1.Fill = Brushes.Violet;
            myPath1.StrokeThickness = ;
            myPath1.Data = cg2;
            Grid1.Children.Add(myPath1);
 
        }
 
    }
}

上面的实例也简单的展示了效果，更多的运用我们可以从msdn上，上面有详细的说明，以及运用方法
