Signature annotation not showing

[CervarlCG]

Hi, i like know if there is support to digital signature?
Actually i try to render a PDF but the signature is not rendering.

I am facing the same problem. The solution I found is commenting out this piece of code in of pdf.worker.js, part of pdfjs-dist package:

if (data.fieldType === "Sig") {
      data.fieldValue = null;
      this.setFlags(_util.AnnotationFlag.HIDDEN);
}

It works but I am not sure if that's the best way to show the signatures :)

It looks like Mozilla PDF.js team has decided not to implement this annotation feature just yet. A comment around this block explains more:

https://github.com/mozilla/pdf.js/blob/4ba28de2608866dcb10d627d77dc19ff3d017c17/src/core/annotation.js#L995-L1002

Given that, we won't be able to do anything about it until Mozilla implements Sig annotation support. Sorry about that.

@wojtekmaj

The new version of pdf.js now supports signature display: https://github.com/mozilla/pdf.js/releases/tag/v2.9.359
Does react-pdf have plans of upgrading in the near future? Thanks

[wojtekmaj]

That's not a new version. That's an unstable pre-release. Once they actually release a new version I'm usually not far behind.

Supporting digital signature visualization will be very great!!!

Support for Sig type has been added in v5.4.0-beta.2.
