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。
