C#画笔Pen绘制光滑模式曲线的方法

本文实例讲述了C#画笔Pen绘制光滑模式曲线的方法。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 Form11 : Form
 {
   public Form11()
   {
     InitializeComponent();
   }
   private void button1_Click(object sender, EventArgs e)
   {
     LinearGradientBrush brush = new LinearGradientBrush(this.ClientRectangle, Color.Empty, Color.Empty, 100);
     ColorBlend blend = new ColorBlend();
     blend.Colors = new Color[] { Color.Red, Color.Green, Color.Blue };
     blend.Positions = new float[] { 0, .5f, 1 };
     brush.InterpolationColors = blend;
     Pen pen5 = new Pen(brush);
     Graphics g5 = this.CreateGraphics();
     Point[] p = new Point[] { new Point(0, 0), new Point(100, 100), new Point(50, 100), new Point(200, 100) };
     g5.SmoothingMode = SmoothingMode.AntiAlias;
     g5.DrawCurve(pen5,p);
   }
 }
}

希望本文所述对大家的C#程序设计有所帮助。
