EDIT: Running this code does open Acrobat

问题 I need to post several (read: a lot) PDF files to the web but many of them have hard coded file:// links and links to non-public locations. I need to read through these PDFs and update the links to the proper locations. I\'ve started writing an app using itextsharp to read through the directories and files, find the PDFs and iterate through each page. What I need to do next is find the links and then update the incorrect ones. string path = \"c:\\\\html\"; DirectoryInfo rootFolder = new

问题 I want to generate a PDF by passing HTML contents to a function. I have made use of iTextSharp for this but it does not perform well when it encounters tables and the layout just gets messy. Is there a better way? 回答1: Update: I would now recommend PupeteerSharp over wkhtmltopdf. Try wkhtmtopdf. It is the best tool I have found so far. For .NET, you may use this small library to easily invoke wkhtmtopdf command line utility. 回答2: EDIT: New Suggestion HTML Renderer for PDF using PdfSharp

问题 Well i\'m trying to merge multiple PDFs in to one. I gives no errors while compiling. I tried to merge the docs first but that went wrong because I\'m working with tables. This is the asp.net code-behind if (Button.Equals(\"PreviewWord\")) { String eventTemplate = Server.MapPath(\"/ERAS/Badges/Template/EventTemp\" + EventName + \".doc\"); String SinglePreview = Server.MapPath(\"/ERAS/Badges/Template/PreviewSingle\" + EventName + \".doc\"); String PDFPreview = Server.MapPath(\"/ERAS/Badges

问题 I have some code that takes 3 different PDF byte arrays and merges them. This code works great. The issue (some people) are having is that each PDF is considered to be a full page (if printed) even if there is only say 4 inches of content on it, thus leaving 7 inches of white space vertically. Then the middle document gets put in and may or may not have vertical white space at the end of it. Then the footer gets put on its own page as well. Here is the code: byte[] Bytes = rv.LocalReport

问题 How to merge multiple pdf files (generated on run time) through ItextSharp then printing them. I found the following link but that method requires the pdf names considering that the pdf files stored and this is not my case . I have multiple reports i\'ll convert them to pdf files through this method : private void AddReportToResponse(LocalReport followsReport) { string mimeType; string encoding; string extension; string[] streams = new string[100]; Warning[] warnings = new Warning[100]; byte[

问题 I\'d like to know if ITextSharp has the capability of converting HTML to PDF. Everything I will convert will just be plain text but unfortunately there is very little to no documentation on ITextSharp so I can\'t determine if that will be a viable solution for me. If it can\'t do it, can someone point me to some good, free .net libraries that can take a simple plain text HTML document and convert it to a pdf? tia. 回答1: I came across the same question a few weeks ago and this is the result
