Hi @manu-gupta

the Reader Extension will not help when the PDF is basically a static PDF running via DocuSign (which might mess with it further). The QRCode XFA object needs to be rendered in the Forms environment (either at client inside Adobe Acrobat or Reader with Reader Extensions or at server in AEM Forms).

At the time of instantiating the PDF in the browser I am sure the QRCode object did not render and will not in this usecase.

You seem to have AEM Forms server (looking at PDFFormRenderOptions which sound like the render API being used).

Assuming that you have a 2 stage process
a) data capture in interactive PDF browser only
b) routing of finished form to DocuSign as static, printable PDF

In the browser you will not be able to have QRCode interactively. You could fill out fields though. The form data is submitted back to a server (either as complete PDF or as data only).

In AEM Forms you could extract the data and re-render with an XDP that contains the QRCode (flattening directly will not help)

This printed version should contain also the QRCode as it was rendered in an XFA friendly environment.

@manu-gupta there are some conflicting facts in your description.

Interactive XFA PDF cannot be opened in browsers without the Reader/Acrobat plugin. The Reader Extensions also only work inside Reader/Acrobat.

Additionally, QR Code and other 2D barcodes need a special Reader Extension to be written decrypted, otherwise you require AEM Forms Barcoded Forms (Right "BarcodePlaintext" which is a separate right and will not come by default). It is possible that the QR Code shows but did you scan it and got your text out as you expect?
