Thanks for you quick reply.
I dug somewhat more:
There is a tool QtQR which e.g. produces
BCD
001
1
SCT
SOLADES1TUB
Landkreis T羹bingen - Kreiskasse
DE43641500200000000048
EUR693.00
5.1099.220039.0
Geb羹hrenbescheid-Nr. 20220039 vom 12.01.2022
(the "Asian" letters should be the German umlaut ü, not sure what is going
wrong there)
So calling an external tool would probably be sufficient and using the response.
QtQR is using python3-qrtools under the hood, which are less then 300 lines of
code.
python-qrtools has a
def decode_webcam(self, callback=lambda s:None, device='/dev/video0'):
function.
Since I scan the invoices with the qrcode anyways using a pdf file as data
source would also be a good approach, though it seems with python3-qrtools the
webcam approach is more straight forward.
I can do more experimenting with python3-qrtools if you think the approach is
viable and somebody is willing to do the gnucash integration:
- Add a button in the SEPA transfer dialog
- Call an external tool
- Process the data as defined by the EPC QR code
- Fill them in the fields of the SEPA transfer form
Many thanks
Rainer
