iText is a PDF library that allows you to CREATE, ADAPT, INSPECT and MAINTAIN documents in the Portable Document Format (PDF):
- Generate documents and reports based on data from an XML file or a database
- Create maps and books, exploiting numerous interactive features available in PDF
- Add bookmarks, page numbers, watermarks, and other features to existing PDF documents
- Split or concatenate pages from existing PDF files
- Fill out interactive forms
- Serve dynamically generated or manipulated PDF documents to a web browser

iText is used by Java, .NET, Android and GAE developers to enhance their applications with PDF functionality.
iTextSharp is the .NET port.

Several iText engineers are actively supporting the project on the iText mailing-list itext-questions@lists.sourceforge.net and on StackOverflow: http://stackoverflow.com/questions/tagged/itext

Yes, but migration from 4.1.x to 5.0, may be long and hard, if you used removed API for Table, Cell ... Second complication is changed most of properties to methods. (e.g. Widths). So if you used Object Initializers the better way is stay with. 4.1.x version

Licence was changes and is now much, much more restrictive. Stick with v4; if you want a commercial product consider Prince (which is much easier to use) instead.

Thanks for quick release of 5.5.5 - 5.5.4 had the "index out of array bounds" issue again. You saved my bacon, as I was just about to look for something else, but didn't want to. Barry

This library is so poorly documented and badly designed it's not even funny.

downloaded the dll and put together a component that merges multiple PDF files into 1. Works as advertised and really fast.

Not sure about the software, although it's pretty obvious that the reviews are mostly fake. Makes you think anyway... I downloaded and there some mumbo jumbo about copyright from Sun. I'm staying away from this potential lawsuit. If you are reading this, you have been forewarned.
