C#设置页面单位和缩放的方法

本文实例讲述了c#设置页面单位和缩放的方法。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;
namespace advanced_drawing
{
  public partial class form2 : form
  {
    public form2()
    {
      initializecomponent();
    }
    private void button1_click(object sender, eventargs e)
    {
      graphics g = this.creategraphics();
      g.pageunit = graphicsunit.inch;
      g.pagescale = 1;
      font rulerfont = new font("ms sams serif", 8.25f);
      pen blackpen = new pen(color.black, 0.05f);
      float rulerfontheight = rulerfont.getheight(g);
      rectanglef rulerrect = new rectanglef(0, 0, 6.5f, rulerfontheight * 1.5f);
      g.drawrectangle(blackpen, rulerrect.x, rulerrect.y, rulerrect.width, rulerrect.height);
    }
  }
}

希望本文所述对大家的c#程序设计有所帮助。
