Question
Adding custom data/form to pdf document
I'm trying to create a pdf document that contains hidden embedded data.
The content of the data would be a text string.
There will be one or more of these fields in each pdf.
Editors would augment the pdf with these fields.
Viewers would never be able to see/access these fields.
The fields would be extracted programatically using a pdf library.
Is this possible?
What are the options?
Thanks!
