Bitmap source = new Bitmap("source.jpg");
            Bitmap bmp = new Bitmap(source.Width, source.Height, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
            Graphics.FromImage(bmp).DrawImage(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
            bmp.Save("result.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
