C#中GraphicsPath的Widen方法用法实例

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 advanced_drawing{  public partial class Form12 : Form  {    public Form12()    {      InitializeComponent();    }    private void Form12_Paint(object sender, PaintEventArgs e)    {      // Create a path and add two ellipses.      GraphicsPath myPath = new GraphicsPath();      myPath.AddEllipse(0, 0, 100, 100);      myPath.AddEllipse(100, 0, 100, 100);      // Draw the original ellipses to the screen in black.      e.Graphics.DrawPath(Pens.Blue, myPath);      // Widen the path.      Pen widenPen = new Pen(Color.Black, 10);      Matrix widenMatrix = new Matrix();      widenMatrix.Translate(50, 50);      myPath.Widen(widenPen, widenMatrix, 1.0f);      // Draw the widened path to the screen in red.      e.Graphics.FillPath(new SolidBrush(Color.Red), myPath);    }  }}
