使用 itextsharp 转换为 PDF 时 HTML 中的图像未正确对齐

Question

I'm using itextsharp to convert my html portion to pdf. Everything is ok but the image always getting aligned left after converting html to pdf

<div align="center"><img src="http://www.uaa.alaska.edu/institutionaleffectiveness/Graduation/images/report_1.jpg" width="120"></div>

C# code:

StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
pnlCertificate.RenderControl(hw);
src = sw.ToString();
AbsolutePath = HttpContext.Current.Request.Url.Scheme + "://" + HttpContext.Current.Request.Url.Authority + HttpContext.Current.Request.ApplicationPath;
src = src.Replace("src=\"/", string.Format("src=\"{0}", AbsolutePath));
StringReader sr = new StringReader(src);
Document pdfDoc = new Document();
pdfDoc.SetPageSize(iTextSharp.text.PageSize.A4.Rotate());
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, new FileStream(path + "/" + _CertificatesEntityCollection.First().Name + ".pdf", FileMode.Create));
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();

Answer 1

ITextSharp does not support Div tag so make use of table

<table width="100%">
    <tr>
        <td align="center">
            <img src="http://www.uaa.alaska.edu/institutionaleffectiveness/Graduation/images/report_1.jpg" width="120">
        </td>
    </tr>
</table>

<div align="center">
