示例
下面的代码示例演示了更改 PageUnit 属性的效果。
此示例旨在与 Windows 窗体 一起使用。 将代码粘贴到窗体中, ChangePageUnit 并在处理窗体 Paint 的事件时调用 方法,作为 ePaintEventArgs传递。
private:
   void ChangePageUnit( PaintEventArgs^ e )
   {
      // Create a rectangle.
      Rectangle rectangle1 = Rectangle(20,20,50,100);
      // Draw its outline.
      e->Graphics->DrawRectangle( Pens::SlateBlue, rectangle1 );
      // Change the page scale.  
      e->Graphics->PageUnit = GraphicsUnit::Point;
      // Draw the rectangle again.
      e->Graphics->DrawRectangle( Pens::Tomato, rectangle1 );
   }
private void ChangePageUnit(PaintEventArgs e)
{
    // Create a rectangle.
    Rectangle rectangle1 = new Rectangle(20, 20, 50, 100);
    // Draw its outline.
    e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1);
    // Change the page scale.  
    e.Graphics.PageUnit = GraphicsUnit.Point;
    // Draw the rectangle again.
    e.Graphics.DrawRectangle(Pens.Tomato, rectangle1);
}
Private Sub ChangePageUnit(ByVal e As PaintEventArgs)
    ' Create a rectangle.
    Dim rectangle1 As New Rectangle(20, 20, 50, 100)
    ' Draw its outline.
    e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1)
    ' Change the page scale.  
    e.Graphics.PageUnit = GraphicsUnit.Point
    ' Draw the rectangle again.
    e.Graphics.DrawRectangle(Pens.Tomato, rectangle1)
End Sub
