How to preset Signature field appearance properties with JavaScript?

[AzuresSkye]

Our organization uses a lot of PDFs with digital sigantures. I'd like to simplify and improve the PDF Forms that I create by using JavaScript to preset the appearance of digital signatures on my forms. The vast majority of our users never use anything other than the default appearance.

The goal is that when the user clicks on the Signature field, the default appearance is the one I've specified. Everything needs to be included in the PDF and happen almost trasnparently. I can't distribute extra files to folks.

Specifically, I want only the signer's Common Name, Title, and Section/Office displayed (Maybe Date, too). I figure I'll need to repurpose "Reason" and "Location" properties for those. But I haven't been able to find a way to either embed a signature appearance file in my PDFs or use JavaScript on the signature field to cause it to display the right info. I've been digging through the SDK and Dev Guide, but use of security handlers and signatureInfo is incredibly vague to me 😞

Can anyone point me in the right direction here?

You can't do it without installing a script file on the local computer of the user.

That is incredibly disappointing to hear. 

To be clear, there's no way to programmatically set the Reason or Location part of a signature either? Those are both manual, unless you use a trusted script, right?

As far as I can see, that's correct.
