My understanding is that you can create PDF documents with iText.
Certainly this is possible. PDF is for creating documents!
This means that the PDF format must encode the presentation in a
structured
way. Otherwise, the PDF viewer cannot reproduce the document.
Thus, it is structured and all the document information including
text is represented in the PDF format.
I thought iText is capable of loading the PDF elements and then
creating a PDF document from them. On that part, I may be wrong.
cheers.
