I'm trying to create and save a Bitmap with Pixel Format set to Dont care ,but i keep getting Parameter not valid exception.

(我正在尝试创建和保存像素格式设置为“不Dont care的位图，但是我一直在获取“ Parameter not valid异常。)

            Bitmap orig = new Bitmap(500,500);
            Bitmap clone = new Bitmap(orig.Width, orig.Height,
                System.Drawing.Imaging.PixelFormat.DontCare);

            using (Graphics gr = Graphics.FromImage(clone))
            {
                gr.DrawImage(orig, new Rectangle(0, 0, clone.Width, clone.Height));
            }
            clone.Save("test.png");
