Hi,
I try your code to generate a barcode on a report.
I had to install "Pillow" (pip install Pillow) to avoid an NoneType error.
How display this new field 'barcode' inside LibreOffice writer ? I try to add a
frame but don't know how to link my binary field and relatorio documentation
seems outdated...
