Question

我想使用img控件在顶部添加公司徽标。但在以pdf格式下载图像时，它不会显示。同时为图像显示远程网址链接，但同时为文件夹的服务器路径提供不显示图像

 <table style="border-collapse: collapse;border: 1px solid;width:666px" align="center">


      <tr style="border: 1px solid;">
            <td style="border: 1px solid;width:50%" colspan="2">

              <img src="img/kst.png" />
             </td>
            <td style="border: 1px solid;width:50%" colspan="2">Hyderabad, India</td>
            <br />
            <br />
        </tr>

背后的代码

string Projname = "Payslip";
                Response.Clear();
                Response.AddHeader("content-disposition", string.Format("attachment;filename=\"{0}.pdf\"", Projname));
                // Response.AddHeader("content-disposition", "attachment;filename=WeeklyReport.pdf");
                Response.Cache.SetCacheability(HttpCacheability.NoCache);
                System.IO.StringWriter stringWrite = new System.IO.StringWriter();
                System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
                design.RenderControl(htmlWrite);

                string myText = stringWrite.ToString();
                StringReader sr = new StringReader(myText.ToString());
                Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
                Response.ContentType = "application/pdf";
                PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
                pdfDoc.Open();
                XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
                pdfDoc.Close();
                Response.End();
                pdfDoc.Dispose();
                design.Visible = false;

Answer 1

使用绝对网址作为src="img/kst.png"的图片来源，尝试使用src="http://yourdomain.com/img/kst.png"

Answer 2

我用这个：

<img src="@System.Web.HttpContext.Current.Server.MapPath("~/Images/????.???")" />

它对我有用。

如果您发布项目，则无法更改PATH

虽然导出html到pdf图像没有显示在asp.net的itextsharp pdf文档中
