Hi,

I frequently handle files that are digitally signed (by myself, as part of court filings) and that I later need to include, eg. as attachments to a letter or other filing, as a copy (without signature).

Eg.: I sign letter n° 1, sent to recipient n° 1; then I write a letter n° 2 with a copy of letter n° 1, which I want to sign in order to send to recipient n° 2.

In Acrobat, when you combine signed files into a PDF, the signature is automatically deleted.

I am trying to replicate this with pdfcpu, but no luck so far:

• "annot remove" deletes the visible signature on top of the signature field, but not the signature field itself;
• "form list" does not list the form field, thus allowing to remove it through "form remove", but only returns a "(signed)" line, like this:

(signed)
Pg L Field     │ Id  │ Name
━━━━━━━━━━━━━━━┿━━━━━┿━━━━━━

I need to be able to delete the signature field because otherwise I cannot digitally sign the newly created file.

1. Is there a way to do this?
2. If not, more simply, is it possible to use any of the "generate" features in pdfcpu to have a 1:1 copy of the PDF file as if it were printed through a PDF printer (which is what I do manually to go around the issue)?

Thank you very much in advance for your help.
