Hi again,
I thought I’d include a “GiroCode”
(https://en.wikipedia.org/wiki/EPC_QR_code) in our publishing house’s
invoices.
While \qrcode[text=something] works, I’d like to use a Lua call, but I
didn’t understand the code (meta-imp-qrcodes.mkxl) far enough.
I don’t need colors, but the code must include CR characters (\n), since
EPC is defined as a multi-line dataset; the TeX macro converts them to
spaces (\par is deleted).
With the zint module, it looks better (vectors instead of bytemap), but
I still can’t get proper linebreaks.
(If this works, I suggest to include this also in CG invoices.)
