Be careful! The line above creates an A4 document.
What are the dimensions of the original document?
Maybe you should use:
Document document = new Document(original.getPageSizeWithRotation(1));
This way the first page of the new document has the
same dimensions of the first page of the original document.

If you only use getDirectContent; add the letterhead first,
then the text. You could also use getDirectContentUnder;
add the letterhead to the 'under' content, and the text
to the 'upper' content. It's your choice.

OK, this answers my initial question; we're working with A4
documents; in this case, you can use x = 0; y = 0.

Of course it is. Did you expect something else?
If you have a typewriter, and you insert paper with
a letter head, you normally don't type text that covers
your letterhead. When creating your original PDF, you
should have thought of that...

That's normal, isn't it?

I don't know what you were expecting.
Do you want to make the letterhead transparent so that
you can see the letterhead and the text? They will still
overlap, but you will be able to see through the letterhead
(of course, if there's a header, it will be transparent too).
Or do you want to shrink the text so that it fits in a
rectangle that is smaller than the letterhead?
That's possible too, but you'll have to define the rectangle;
iText doesn't know where you want to insert the text.
