That solution should work.
I should be able to resize my second document and display it right after the first one (a small fixed size description table).
Thanks for the idea,
Aymeric.

Bruno's answer is absolutely correct in the general case. iText can't figure out how tall the content of a given page is, but knows the precise dimensions of each page. So adding pages whole is easy, but adding content is all-but-impossible.HOWEVER, if your input is relatively fixed (each PDF will always be less than half a page for example), then you can write some code that will draw those two pages on a single page. I believe there's even a semi-related example on the examples page...Ah yes, "TwoOnOne", the first "Manipulating existing PDF documents" example:It scales two input pages down so they'll both fit on a single output page. In your case, if you know they'll both fit when placed in some particular arrangement at their original size, then by all means, do so. You can leave unfilled portions of the source pages "hanging" outside the output pages visible area. Perfectly legal.The down side of this approach is that if your input format ever changes, your output will get Ugly. A page's content might be drawn on top of the other's, or that content may continue off the bottom of the page.If you're generating these files yourself, you're in a better position. You can embed the vertical height of the page's content in your initial pages to be sucked up later and used for page positioning. Have a look at the "page events" examples. You could write an EndPage handler that called PdfWriter's getVeritcalPosition() and put that number in the documents 'info' dictionary:writer.getInfo().put( new PdfName("PageY"), new PdfNumber( verticalPos ) );You could then extract the information later with PdfReader's getInfo():PdfObject yObj = reader.getInfo().get( new PdfName("PageY" ) );float yPos = ((PdfNumber)yObj).floatValue();In production code you'd want some error checking of course (yObj != null && yObj.isNumber()).--Mark Storer

My wife is from Belgium too but she never told me about that. I need to dig that out...> Concerning your question: PDF is not a Word Processing Format.

That's the way I understood it, but I needed a confirmation. Thanks for the anwer,
Aymeric.
