```csharp
            // begin
            Bitmap b = new Bitmap(128, 128);
            var corners = new Point[] {
                new Point(1,1),
                new Point(200,20),
                new Point(2,15)};
            using (Graphics g = Graphics.FromImage(b))
            {
                g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.None;
                g.Clear(System.Drawing.Color.Black);
                g.FillPolygon(System.Drawing.Brushes.White, corners);
            }
            // end
            byte[,] mask = new byte[b.Width, b.Height];

            for (int y = 0; y < b.Height; y++)
                for (int x = 0; x < b.Width; x++)
                {
                    mask[x, y] = b.GetPixel(x, y).R > 0 ? (byte)1 : (byte)0;
