Visible signature

Hi,

Great tool! Just a quick question . . . when I insert a visible signature into a pdf, is it intended to be editable, rather than embedded in the page? A user could edit/remove this object, I'm just wondering if that is by design :) Here's my insert code:

java -jar open-pdf-sign.jar \
  --input /home/AgoutiMatriarch/pdfsup/viuLibraryTweets2009.pdf --output /home/AgoutiMatriarch/pdfsup/viuLibraryTweets2009sign.pdf \
  --certificate /var/lib/caddy/.local/share/caddy/certificates/acme-v02.api.letsencrypt.org-directory/oldtweets.viulibrary.ca/oldtweets.viulibrary.ca.crt --key /var/lib/caddy/.local/share/caddy/certificates/acme-v02.api.letsencrypt.org-directory/oldtweets.viulibrary.ca/oldtweets.viulibrary.ca.key \
 --width 2  --left 1 --top 6 --page -1 --image /home/AgoutiMatriarch/pdfsup/smallVIU.png \
  --hint "https://crt.sh/?id=8038

Thanks for considering :)

Hi Dan!

Thanks for the feedback!
The visible signature is embedded in an annotation, as defined in the standard, but should seem editable. In which PDF reader do you see these editable signature? I can't reproduce in Adobe Reader, PDF-XChange reader and PDF.js

Hi @cproof

My apologies. You are correct. I can remove the box, but I cannot edit the the content (in any reader). This makes much more sense :)

Thanks again.
