iTextSharp: Center align image in PDF when exporting HTML to PDF C# .Net

hi, I am using this code to export to pdf. But while using image

<div align="right">
<asp:Image ID="imgphoto" runat="server" Height="130px" Width="130px" align="absmiddle"  />

</div>

Image in the pdf file is not taking this size , its coming in the bigger size and not geting aligned to right. Text got aligned properly.

  Response.ContentType = "application/pdf";
  Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
  Response.Cache.SetCacheability(HttpCacheability.NoCache);
  StringWriter sw = new StringWriter();
  HtmlTextWriter hw = new HtmlTextWriter(sw);
  this.Page.RenderControl(hw);
  StringReader sr = new StringReader(sw.ToString());
  Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 40f, 30f);
  HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
    
  FileStream(pdfFilePath + "/TestPage.pdf", FileMode.Create));
  PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
  pdfDoc.Open();
     
  htmlparser.Parse(sr);
  pdfDoc.Close();
  Response.Write(pdfDoc);
  Response.End();
