Q: How do I remove Acrobat’s Rights Enable info from PDF?

My PDF is not secured with a password it just has the extended rights in reader to allow saving of forms 7 annots.

I’m pretty sure it’s something at cos level that need to be ripped?

A:

You could use the following lines:

// Remove Adobe’s Rights enable dictionary

doc.GetRoot().Erase(“Perm”);

Obj view_prefs = doc.GetRoot().FindObj(“ViewerPreferences”);

if (view_prefs != null) view_prefs.Erase(“Rights”);

doc.Save(…)

Working now just a minor typo in your code needed to be

doc.GetRoot().Erase(“Perms”);
