Could this also be implemented by choosing a qr-code provider / API ?
For example: a link to this page could be generated with following URL:
https://api.qrserver.com/v1/create-qr-code/?size=230x230&margin=10&data=https://meta.discourse.org/t/possible-to-share-a-post-by-save-a-picture-with-a-qr-code/190012
Or even better using the shorter form
https://api.qrserver.com/v1/create-qr-code/?size=230x230&margin=10&data=https://meta.discourse.org/t/190012
I would appreciate pointers how to add this to a theme.
In my case I am looking for an easy solution to get a printout of a topic including a link provided by QR code.
