Hi Pawel,

PdfSignatureAppearance properties are based on Adobe Acrobat’s “Customize Signature Appearance” window:

AdobeAcrobatCustomizeSignatureAppearance
AdobeAcrobatCustomizeSignatureAppearance1040×845 157 KB

Since it did not provide an option for “Contact info” text to be included in the signature appearance, neither did we.

We can implement this for you.
Just tell us where you want “Contact info” to be included.
The current order is: Name, DistinguishedName, Reason, Location, Date, ComponentVersion.
We think that the most appropriate place would be between DistinguishedName and Reason.
Would that work for you?

Regards,
Stipo

yes, but is like nice to have. If You can add it please add it as optional / backward compatible.

Note that this is a hidden (unlisted) version. To install it, you’ll need to run the above command on the NuGet Package Manager Console (Tools → NuGet Package Manager → Package Manager Console).

Does this solve your issue?
