Subject RE: Adding a Redaction annotation (without applying it)
Date Thu, 22 Jun 2017 09:52:14 GMT
Hi Gilad,

Yes - by "stamping" I mean applying the redactions (i.e. texts, boxes, arrows - everything
that XFDF allows) onto the PDF and then exporting a new one.
We do this as part of a rendering component for electronic files. Therefore we take 2 file:
1) the original PDF (unmodified)
2) the annotation file as XFDF
Then we merge them together on the fly and give it to the viewing component as a readonly
new temporary PDF document.

XFDF is supported by Adobe and other viewers, i.e. Qoppa viewer and the Foxit Web Viewer also
directly deal with XFDF as separate files. You give them both files and they merge it for
display on the fly.
When using PDF.js as a viewer or another component which natively does not support XFDF annotations,
you might go the same way as we do - render on the fly.

If you need some sample code ("XFDF stamping") to start with, we might be happy to help.
Tilman and the PDFBox team were so kind to help us initially here, so we might help you now
and give some knowhow back.

Kind regards,
 Matthias

Hi Matthias,

Thanks for the info.
What do you mean exactly by "stamping" the XFDF file, though? Do you mean just import it?
Does that actually apply the redactions?
