    {
        //Instantiation of DocIORenderer for Word to image conversion
        using (DocIORenderer render = new DocIORenderer())
        {
            //Convert the first page of the Word document into an image.
            Stream imageStream = wordDocument.RenderAsImages(0, ExportImageFormat.Jpeg);
            //Reset the stream position.
            imageStream.Position = 0;
