本文实例讲述了C#中GraphicsPath的Widen方法用法。分享给大家供大家参考。具体如下：

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 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);
    }
  }
}

希望本文所述对大家的C#程序设计有所帮助。
