我没有用pdf获取图像我只得到文字,请帮助我, 我正在使用来自http://sourceforge.net/projects/itextsharp/
的iteshsharp 5.2.1默认代码.aspx.cs
Response.ContentType = "application/pdf";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
savetopdf.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
default.aspx的代码
<form id="form1" runat="server">
<div id="savetopdf" runat="server">
<asp:Label ID="lbl" runat="server" Text=" Lorem Ipsum, Dolor"></asp:Label>
<img src="http://localhost:5583/WebSite1/images/Penguins.jpg" alt="penguins" />
<img src="http://localhost:5583/WebSite1/images/Tulips.jpg" alt="tulips" />
</div>
</form>

HTMLWorker是错误的,并已停止使用XMLWorker。

演示:

即使文档引用了Java API,对C#的适应也应该是直截了当的:

尝试这样:
string ImagePath = Server.MapPath("/Images/Printbanner1.jpg");
Document document = new Document();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=xxx.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
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);
htmlTable = htmlTable.ToString().Replace("'", "\"");
htmlTable = htmlTable.Replace("px", "");
StringReader sr = new StringReader(htmlTable.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(ImagePath);
pdfDoc.Add(image);
htmlparser.Parse(sr);
pdfDoc.Close();
