C#图片添加水印

工作中写的一个图片加水印的小方法，记录在这里

    /// <summary>
    /// 创建水印图片
    /// </summary>
    /// <param name="newFileName"></param>
    public void createImage(string newFileName)
    {
        this.FileUpload1.SaveAs(Server.MapPath("../uploadFile/temp/") + newFileName);
        string FilePath1 = Server.MapPath("../uploadFile/temp/") + newFileName;
        string FilePath2 = Server.MapPath("../uploadFile/member/01.png");
        System.Drawing.Image image1 = System.Drawing.Image.FromFile(FilePath1);
        System.Drawing.Image image2 = System.Drawing.Image.FromFile(FilePath2);
        Graphics g = Graphics.FromImage(image1);
        g.DrawImage(image2, image1.Width / 8, image1.Height / 8, 
                 (image1.Width-image1.Width/4), (image1.Height-image1.Height/4));
        image1.Save(Server.MapPath("../uploadFile/member/" + newFileName),
                 System.Drawing.Imaging.ImageFormat.Jpeg);
        g.Dispose();
        image1.Dispose();
    }
