问题 I want to insert a paragraph (which will word-wrap over several lines) into a PDF document using iTextSharp, but I want to restrict the width of the paragraph to the left half of the page. I see no "width" property for the Paragraph class, but surely there is a way to do this, stimmt? UPDATE The supposed answer doesn't work for me because it uses iText (Java) stuff apparently unavailable in iTextSharp (C#). Specifically (to begin with, there might be more): ct.setSimpleColumn(myText, 60, 750,

问题 I'm having an issue reading an existing pdf for regular expression matches, then extracting those pages to a new pdf. I've run into some issues with this as a whole. I've decided to clear my head and start again from scratch. I'm able to take a 3 page pdf and extract the pages individually into a new file using this code: static void Main(string[] args) { string srcFile = @"C:\Users\steve\Desktop\original.pdf"; string dstFile = @"C:\Users\steve\Desktop\result.pdf"; PdfReader reader = new

How can I pass an Excel created with XML to PDF MVC

问题 I need to create a PDF from an Excel created with XML. My application is based on MVC 4.0. Searching I found ITextSharp but I can't find examples of code or something like that. How can I export to PDF from Excel using ITextSharp? 回答1: First, separate the program from the file format and the API. Excel is a desktop spreadsheet program. XLS and XLSX are binary file formats for storing spreadsheet information. Open XML is a broad subject but usually refers to either the zipped XML file format

I tried setting the family in html as well. <body face = 'Arial

问题 While extracting text from PDF file using iTextSharp, I am getting this error: "Could not find image data or EI" This error occurs on particular pages that contains image only. Could the reason be because I am trying to extract the text without checking whether there is any text content in the page? 回答1: Inline images are not specified very well in the PDF specification. The image data should be contained between ID and EI operators. But there's a possibility the image data itself contains

问题 Using iTextSharp version 5.5.8 (same bug existed in 5.5.7), there's an unpleasant bug when you add images to Chapters and Sections - the images and the section headings start out OK but quickly become offset relative to each other. The PDF generated from the following code starts out correctly, it says "Section 1" and below it is the image. The next section ("Section 2") has a little of the image overlapping the section text, the next section is even worse, etc. I think it's the text that's

File: \\networkshare\savedPDF.pdf Looking at the source code I see that it was not able to get the file stream: inp = BaseFont.GetResourceStream(filePath); if

问题 I've tried a number of different variations to output a very basic PDF from memory but all seem to return the same result, which is to say it doesn't actually return anything.

Here is my code in its current state: MemoryStream ms = new MemoryStream(); Document doc = new Document(); PdfWriter writer = PdfWriter

问题 I'm trying to store and update a string in the PDF file catalog using the iTextSharp library. I'm able to do this without issue in a standard desktop application but I'm unable to get it to save on a SharePoint server (As part of a SharePoint feature which is written in C#).
