问题 I am using iTextSharp to create on PDF document, later i want to add "Adding Enable for commenting Adobe Reader" using Acrobat, but i getting error as You do not have permission to write to this file Here my code used to create PDF file: using (FileStream FS = new FileStream(dPDFFile_temp, FileMode.Create, FileAccess.Write, FileShare.None)) { using (Document Doc = new Document()) { using (PdfCopy writer = new PdfCopy(Doc, FS)) { Doc.Open(); for (int i = 1; i <= R.NumberOfPages; i++) { writer

问题 This is how I managed my font so far: BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1250, BaseFont.EMBEDDED, false); Font titleFont = new Font(bf, 20); Now, I want to set monospaced (fixed width) font for purpose of string formatting. Do I have to download some ttf file (as I was reading about it) or there is monospaced font already included in iTextSharp 回答1: If you don't want to embed a font, you can use this: BaseFont bf = BaseFont.createFont( BaseFont.COURIER, BaseFont

问题 I recently discovered iTextSharp. I was investigating a performance issue with the rendering of PDF documents and Bruno Lowagie (author of iText) kindly explained to me the reason why I was experiencing such an issue : it was due to the amount of "Inline Images" in my PDF documents. He also explained the basics to remove those "Inline Images"... (My purpose is to "possibly" show a preview of the document with a clear notice that it's not the actual document and that this one could be very

问题 In my c# code I am extracting text from a pdf, and I have two methods of doing it. However 1 method works for 1 type of pdf document and the other method works for the other type of pdf document. When method 1 fails, I get the text but without any whitespaces, and when method 2 fails, I get only \r\n. Method 1 (class from http://www.codeproject.com/Articles/14170/Extract-Text-from-PDF-in-C-100-NET) PDFParser pdf_parser = new PDFParser(); currentText = pdf_parser.ExtractTextFromPDFBytes

问题 I have an application that displays password protected PDFs using iTextSharp. pdfCopy.SetEncryption(true, "Secretinfo", "Secretinfo", 0); If the user saves the PDF, the saved copy of the PDF is password protected. Which is great. The problem is it also prompts for password before displaying the PDF on the browser. Which isn't good. So I'm thinking maybe it's possible to supply the password using javascript just to display it on the browser. It's bad practice but I don't see that I have any

问题 I have written some code that merges together multiple PDF's into a single PDF that I then display from the MemoryStream. This works great. What I need to do is add a table of contents to the end of the file with links to the start of each of the individual PDF's. I planned on doing this using the GotoLocalPage action which has an option for page numbers but it doesn't seem to work. If I change the action to the code below to one of the presset ones like PDFAction.FIRSTPAGE it works fine.
