在Pdf文件中绘制Html字符串内容 [英] Drawing Html String Content in Pdf File

问题描述

大家好，

我有一个字符串，这是一个html页面内容，我想将此内容绘制为pdf文件，或将html页面转换为pdf文件。我之前搜索了很多，我发现了很多代码，但他们都使用现成的库，如iTextSharp和DynamicPDF ....，我不想要这个，如果有任何机构知道任何其他解决方案，请告诉我是


谢谢

这是一种方法，开源pandoc： http://johnmacfarlane.net/pandoc/ [ ^ ]。



我希望你知道HTML。您可以使用iText或其.NET端口iTextSharp创建PDF：

http：//en.wikipedia .org / wiki / IText [ ^ ]，

http://itextpdf.com/ [ ^ ]，

http：// sourceforge .net / projects / itextsharp / [ ^ ]，

http://www.javatips.net / blog / 2011/09 / create-pdf-with-itext-java-tutorial [ ^ ]。



我也提供了Java参考，因为大多数那里有文件。如果您了解C＃，那么理解它就不会有问题。



请注意，HTML和PDF概念非常不同，因此一对一的通信不能成立。 HTML很流畅，但PDF在格式化纸质文档中更像是固定的。您可以为一些典型的HTML渲染案例创建一些合理的映射（可能带有选项）。

当我使用ITextSharp编写此代码时，一个例外告诉我路径不是合法形式。

  string  table1 = GetHtmlPage（我的HTML代码）; 
 StringReader reader =  new  StringReader（table1）; 
凭证凭证= 新凭证（PageSize.A4）; 
 HTMLWorker parser =  new  HTMLWorker（document）; 
  string  PDF_FileName = Server.MapPath（  〜）+   / Shopping_cart / billformat / PDF_File.pdf; 
 PdfWriter.GetInstance（document， new  FileStream（PDF_FileName，FileMode.OpenOrCreate））; 
 document.Open（）; 
 尝试 
 {
 parser.Parse（reader）; 
} 
  catch （例外情况）
 {
段落段落= 新段落（ 错误！ + ex.Message）; 
 Chunk text = paragraph.Chunks [ 0 ]  as  Chunk; 
  if （text！=  null ）
 {
 text。 Font.Color = BaseColor.RED; 
} 
 document.Add（paragraph）; 
} 
 最后 
 {
 document.Close（）; 
} 
 

任何帮助!!!!!!!!!!!!!!!! ！

This is one of the approaches, open-source pandoc: http://johnmacfarlane.net/pandoc/[^].

I hope you know HTML. You can create PDF using iText, or its .NET port, iTextSharp:
http://en.wikipedia.org/wiki/IText[^],
http://itextpdf.com/[^],
http://sourceforge.net/projects/itextsharp/[^],
http://www.javatips.net/blog/2011/09/create-pdf-with-itext-java-tutorial[^].

I provided Java reference, too, because most of the documentation is there. If you know C#, you won''t have problem to understand it.

Note that HTML and PDF concepts are very different, so one-to-one correspondence cannot be established. HTML is fluid, but PDF is more like a fixed in its formatting paper document. You can create some reasonable mapping (perhaps with options) for some typical cases of HTML rendering.

when i wrote this code using ITextSharp, an exception tells me "The path is not of a legal form."

string table1 = GetHtmlPage(MY HTML CODE);
       StringReader reader = new StringReader(table1);
       Document document = new Document(PageSize.A4);
       HTMLWorker parser = new HTMLWorker(document);
       string PDF_FileName = Server.MapPath("~") + "/Shopping_cart/billformat/PDF_File.pdf";
       PdfWriter.GetInstance(document, new FileStream(PDF_FileName, FileMode.OpenOrCreate));
       document.Open();
       try
       {
           parser.Parse(reader);
       }
       catch (Exception ex)
       {
           Paragraph paragraph = new Paragraph("Error!" + ex.Message);
           Chunk text = paragraph.Chunks[0] as Chunk;
           if (text != null)
           {
               text.Font.Color = BaseColor.RED;
           }
           document.Add(paragraph);
       }
       finally
       {
           document.Close();
       }
