            InitializeComponent();

            GraphicsPath GP = new GraphicsPath();
            GP.AddRectangle(new Rectangle(0, 50 - 1, 100, 2));
            GP.AddRectangle(new Rectangle(50 - 1, 0, 2, 100));

            Bitmap Bmp = new Bitmap(100, 100);
            using (Graphics G = Graphics.FromImage(Bmp))
                G.FillRectangle(Brushes.Red, new Rectangle(0, 0, 100, 100));

            PictureBox PB = new PictureBox();
            PB.Size = new Size(100, 100);
            PB.Parent = this;
            PB.Image = Bmp;
            PB.Region = new Region(GP);
            PB.Location = new Point((this.Width - PB.Width) / 2, (this.Height - PB.Height) / 2);
