See qpdf. Rittich: Thx for the comment In what way do you think does this open a new perspective on the problem? Did you think we don't know that we can add or remove text this way? KursPfeifle: I do not make any assumptions on what you know. The answer states that editing a PDF this way needs to preserve the byte offsets of the objects in the file. It is, however, possible to change the byte offsets when later correcting them by using fix-qdf.
