How to change a PDF but preserve the rights 2007-12-03 - By Samuel B. Quiring
Back
I have a PDF containing an XFA form; isXfaPresent() == true. The PDF was
authored so that it can be opened in Adobe Reader, fields in the form can be
filled, and the form can be saved by Reader to the file system.
Using iText I have read in the PDF, obtained the XfaForm, changed values in the
XML Document, and written a new PDF to the file system.
The PDF I write out contains the values I put into the XML, but the rights to
save the PDF from Reader have been lost. Is this expected? Other features of
the original PDF are also lost in the newly-written PDF.
I wrote the changed PDF to a new file. If this is the reason the save rights
were lost, is there a way I can modify the existing PDF in place so that the
rights to save the file from Adobe Reader are maintained?
