    {
      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);
    }
  }
}
