Please a) provide your code in a way one can copy&paste, not as image. If people want to reproduce your issue to help you, they hardly will have to type it in by hand... b) provide a sample PDF output on which one can observe and analyze the error. c) move your question to stackoverflow where meanwhile the public iText support takes place.
