QR Code in PDF formular

[ste1011]

Hello, I would like to add a QR Code to a PDF template.
Is it possible to define line breaks in the template

{{barcodeImage 'Test\nTest1\nTest2' type='QRcode' width=60 height=60 padding=0}}

or is there a way to call a custum helper like this:

{{barcodeImage {{qrCode "qrUrlString" "200x200"}} type='QRcode' width=60 height=60 padding=0}}

Thanks in advance
Stephan
