Re: [iText-questions] How to change a PDF but preserve the rights
It can't.
If you make ANY changes to the PDF you will break the rights. It's
specifically designed this way to detect tampering.
The only choice you have, if you wish to distribute a file with
Reader Enablement is to purchase Adobe LiveCycle ES and have it
process your document AFTER you do whatever dynamic functionality you
wish.

It _IS_ possible to fill in a PDF that has been Reader Enabled w/
o violating the rights - but it MUST be done in a very specific
fashion using append mode on the source PDF AND only modifying a
limited number of objects in the PDF.
So yes, if you are going to create a whole new PDF - you'll break
the Reader Enabling. If you're careful about what you do, and
how you do it, you CAN accomplish your goal.

Re: [iText-questions] How to change a PDF but preserve the rights
Trying to modify a Reader Enabled XFA-based PDF, without breaking the
enablement is near impossible I don't recommend it.

Hello,
I´m also trying to achieve the same: change somes aspects of an
extended PDF file without breaking extended functionality.
The aspects I´m trying to change using iText is the data section
and the scripts section of the xfa DOM. Using the code below, I´m
able to change both but:
# if I call stp.AcroFields.Xfa.Changed = true; the rights will be lost
# if I not call stp.AcroFields.Xfa.Changed = true; the data will
not be merged
Even If I just create a stamper and call
stp.AcroFields.Xfa.Changed = true; without changing anything in
the PDF, the rights will be lost, so I suppose this line of code is
the problem.
So, my question is, what this line of code does? If I don´t call
this property, my data will not be merged, but it will be inside
the PDf, because the resulting PDf is bigger.
That is way I was wondering if we can call something like this
using code inside the PDF (after the user opened it) instead of
using iText. iText would place the data and the code into the PDF,
but the changed flag would be activated inside the PDF using
LiveCycle designer code.
Thank you

It _IS_ possible to fill in a PDF that has been Reader Enabled

So yes, if you are going to create a whole new PDF - you'll

Re: [iText-questions] How to change a PDF but preserve the rights
It _IS_ possible to fill in a PDF that has been Reader Enabled w/o violating the rights - but it MUST be done in a very specific fashion using append mode on the source PDF AND only modifying a limited number of objects in the PDF. So yes, if you are going to create a whole new PDF - you'll break the Reader Enabling. If you're careful about what you do, and how you do it, you CAN accomplish your goal.

Re: [iText-questions] How to change a PDF but preserve the rights
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. I feel like I'm missing something. You've got a PDF that appears to have at least PdfWriter.ALLOW_FILL_IN. If the form has that permission (retrieved from PdfReader.getPermissions()) then your code should allow you to fill in the form. If it has other permissions too then just set the output PDF with the result of PdfReader.getPermissions() using the PdfEncryptor. Something on the order of: PdfReader reader = new PdfReader( input.pdf ); int pdfPermissions = reader.getPermissions(); if( !(pdfPermissions PdfWriter.ALLOW_FILL_IN)) // throw exception? exit? either way, don't allow the form to be filled // // modify the pdf contents as needed // PdfEncryptor.encrypt( reader, new FileOutputStream( output.pdf), null, null,// no user name and password pdfPermissions, true); I apologize if I've missed something but it seems that, based on your original question, this is what you wanted.

It's one of the many sources of revenue for the company. You won't find any other product that allows you to do what you want. br, Bruno smime.p7s Description: S/MIME Cryptographic Signature - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
