iText - add content to the bottom of an existing page

Question

I want to add a piece of text to every page of a PDF file. This answer in SO works fine. But, the text is added to the top of the page. I would like to add my text to the bottom

Answer 1

Have a look at chapter 6 of iText in Action, 2nd edition, especially at subsection 6.4.1: Concatenating and splitting PDF documents.

Listing 6.22, ConcatenateStamp.java, shows you how you should create a PDF from copies of pages (in your case: all pages) of multiple other PDFs; the sample additionally adds a new "Page X of Y" footer; this demonstrates how you can add content at given positions on the pages while merging the source files.
