Graphics g = this.CreateGraphics();
Pen p = new Pen(Color.Red);
Point p1 = new Point(5,285);
Point p2 = new Point(269,183);
Point p3 = new Point(398,292);
Point p4 = new Point(815,362);
Point p5 = new Point(814,578);
Point p6 = new Point(261,578);
Point p7 = new Point(2,404);
Point[] pa ={ p1, p2, p3, p4, p5, p6, p7 };
g.DrawPolygon(p,pa);
