ITextSharp不会从本地页面生成图像到pdf

Question

我正在使用ItextSharp从我的aspx页面生成Pdf。我的页面包含大量图像但Itext sharp不会将图像渲染为PDF。

我认为问题在于从我的页面下载Html的方式。它只渲染Html而不是图像，因为图像需要时间来渲染。

 protected void btnGenerateReport_Click(object sender, EventArgs e)
    {
        WebClient myClient = new WebClient();
        string myPageHTML = null;
        byte[] requestHTML;
        // Gets the url of the page

        string currentPageUrl = Common.GetAppSettings("SiteURL") + "client/ClientPDFHtml.aspx";

        //UTF8Encoding utf8 = new UTF8Encoding();

        // currentPageUrl = "http://www.yahoo.com"; 

        //requestHTML = myClient.DownloadData(currentPageUrl);

        //myPageHTML = utf8.GetString(requestHTML);

        System.Net.WebRequest objRequest = System.Net.HttpWebRequest.Create(currentPageUrl);
        StreamReader sr = new StreamReader(objRequest.GetResponse().GetResponseStream());
        myPageHTML = sr.ReadToEnd();
        sr.Close();



        Document document = new Document();

        PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\\outfile1.pdf", FileMode.Create));
        document.Open();
        iTextSharp.text.html.simpleparser.StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
        iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
        hw.Parse(new StringReader(myPageHTML));
        document.Close();

        Response.ClearContent();
        Response.ClearHeaders();
        Response.AddHeader("Content-Disposition", "inline;filename=outfile.pdf");
        Response.ContentType = "application/pdf";
        Response.WriteFile(Request.PhysicalApplicationPath + "\\outfile1.pdf");
        Response.Flush();
        Response.Clear();


    }

以上代码在包含图像的项目中请求我的aspx页面。

<div>
    <h1 style="font-family: arial; color: #00007B; text-align: center; font-size: 34pt">
        Test Data
        <br />
        Text Paragraph</h1>
</div>
<div style="text-align: center;">
    <img src="http://localhost:2244/assets/images/ReportImages/image00.png"
        alt="image" height="150px" width="275px" />
</div>

这是html的一部分
