      InitializeComponent();
    }
    private void Form11_Paint(object sender, PaintEventArgs e)
    {
      Matrix matrix=new Matrix();
      matrix.Translate(10, 10);
      GraphicsPath path = new GraphicsPath();
      path.Transform(matrix);
      Rectangle rect = new Rectangle(0, 0, 100, 100);
      Graphics g = e.Graphics;
      path.AddRectangle(rect);
      g.DrawPath(Pens.Black, path);
      path.Flatten(matrix, 10);
      g.DrawPath(Pens.Red, path);
    }
  }
