使用itextsharp直接在PDF中插入HTML [英] Insert HTML directly in PDF using itextsharp

问题描述

我有WPF应用程序，用户在富文本框（rtb）中输入一些文本，我将该rtb字符串转换为HTML，然后将该HTML转换为图像，然后将其插入PDF文档

I have WPF application in which user enters some text in rich text box(rtb), I convert that rtb string to HTML and then convert that HTML to image and then insert it in the PDF document

using (Stream inputPdfStream = new FileStream("sample.pdf", FileMode.Open, FileAccess.Read, FileShare.Read))
using (Stream outputPdfStream = new FileStream("result2.pdf", FileMode.Create, FileAccess.Write, FileShare.None))
{
  var reader = new PdfReader(inputPdfStream);
  var stamper = new PdfStamper(reader, outputPdfStream);

  PdfContentByte pdfContentByte = null;

  int c = reader.NumberOfPages;
  iTextSharp.text.Image image =   TextSharp.text.Image.GetInstance(ConvertXamltohtmltoImage(xamlstring));

  foreach (var item in lst)
  {
      image.ScaleToFit(item._Size.Width, item._Size.Height);
      image.SetAbsolutePosition(item.Location.X, item.Location.Y);
      pdfContentByte = stamper.GetOverContent(item.pageNo);
      pdfContentByte.AddImage(image);
  }
  stamper.Close();
}

我的问题是我可以直接将HTML插入PDF吗？

你需要一个额外的DLL才能做到这一点： http://sourceforge.net/projects/itextsharp/files/xmlworker/

不幸的是，该文档最近没有更新。我们正在努力。
