Currently, you cannot change digital signature details or text color (the default color is blue). However, we’ve logged an investigation ticket with ID SIGNATURENET-3134 in our internal issue tracking system. Hence, this scenario will be further investigated and you’ll be notified about the outcomes.
Currently I am using the trial version…my client is going to buy the license …so what are the changes I have to made in the code after the license is bought?
Once you have the subscription. You just have to load or apply the API license in order to avoid evaluation limitation. Other changes or the code stays as it is.
@abhratanu, next GroupDocs.Signature release will include customization of this PDF Digital Signature appearance that will allow to apply custom labels or hide them, same as changing Font and hopefully background (it’s an open ticket at this moment)
Thank you for your request on this!
@abhratanu, please be aware that we released GroupDocs.Signature 20.10
The Release Notes topic is available here
At this moment there’s no ability to customize Font color, but there are another options to adjust the appearance. Please find example in the release notes.
We made a request to PDF support team about changing digital font color option.
Thank you
