Greetings @sabardotnet!

This library uses Mozilla's PDF.js v2.7.570 underneath to render the files. Until v2.9.359, PDF.js didn't show digital signature widgets. I've sent a PR updating it to the latest version, but for now, you have to implement a small 'fix'.

Please, see my comment on the issue #810, where I explain a 'fix' used to render the signature while PDF.js's version isn't updated.

Cheers!

Any update on this? I saw that the PR has conflicts

Hey @sebalr !

Actually, my PR updating PDF.js to 2.11.338 was merged! It'll be available in ng2-pdf-viewer's next release!

Can we close this? 7.0.2 was released, did it fix this issue?

Hello, I am using 7.0.2 version of ng2-pdf-viewer. This issue with displaying signature seems to be not resolved. I am using pdf with Adobe signature, but the signature is not displayed when the pdf is loaded (other elements are loaded properly like inputs or checkboxes, etc.). When I get annotations from the component API I see that there is an element with fieldType of 'Sig'. I tested it as well on the playground page and the 'Sig' element is not displayed. Any update on this issue?
