iText RUPS

The PDF Diagnostic Tool for Reading and Updating PDF Syntax & Debugging PDF code.

Our PDF diagnostic tool for reading and updating PDF Syntax is built on iText Core and offers a crystal-clear look on how your PDF is constructed and makes it possible to inspect the PDF Syntax for possible errors. Since pdfDebug is included in the diagnostic tool, you can easily see any code errors and debug PDF code while you are still programming, fixing them immediately. No more need of having to spend a lot of time, searching through a finished, yet faulty complex PDF document to find a coding error.
