ACS Community 6.2 pdf viewer does not show digital signature on pdf document

[Peter_Adam_SB]

Is it possible to set the 201911GA pdf viewer to show the digital signature? 4.2.f community showed it.

Now on the small thumbnail there is there the digital signature (bottom right corner):

If we download the original via ACS the signature is visible.

Alfresco pdf converter config:

alfresco-pdf-renderer.root=/opt/alfresco-6.2.0/alfresco-pdf-renderer
alfresco-pdf-renderer.exe=/opt/alfresco-6.2.0/alfresco-pdf-renderer/alfresco-pdf-renderer

Transform services (is it related?):

transform.service.enabled=false
local.transform.service.enabled=false
legacy.transform.service.enabled=true

Document Preview framework changed from 4.2.f (Flash) to 5.0 (pdf.js).

Since pdf.js doesn't support digital signature preview (https://github.com/mozilla/pdf.js/issues/1076), Alfresco is not displaying this field in Share.

It should be worthy to add this feature to the product.

You could open a ticket with this request in https://issues.alfresco.com

Registered and tried, but was unavailable. Problem with a field (not marked which), correct it or contact administrator for check the log.

Jira is more inhumane than our OTRS, quite the feat.

As far I know, it is possible with a minor modification. Check the following link for modifying pdfjs properly:

Kind regards.
