UPN QR Code = standard QR Code but must be version 15 (size 77x77), must use ECC level M, must use ECI 4 (ISO-8859-2), and must use byte mode encodation.
Looks promising! Give me a few days to review and provide more detailed comments.
First pass, this seems to be a decoding bug in J4L Barcode Vision. I've checked the output of `Pdf417Test.testSetContentBytes()` against ZXing, a phone app, and a hardware barcode scanner, and...
Have you reported the (possible) J4L Barcode Vision decoding bug to the J4L team? I think fixing that defect would be the ideal scenario, rather than trying to add workarounds...
I'm not sure, trying to remember where we left this... do you have the sample content and settings used to generate the test barcode above?
Thanks, I'll take a look in the next few days. Do you have a realistic sample Swiss e-tax return barcode(s) without any PII? It might be good to add something...
The difference between the two is in the compaction mode. There are a few options for how PDF417 can encode data internally, and the most optimal encoding mode is chosen...
Thanks for the confirmation! I'm hesitant to add full-fledged compaction mode selection support. First, none of this should be necessary, so keeping the support as minimal as possible is attractive....
> Tests look good so far, thanks a lot! Great, thanks for checking. > I have not found any other PDF417 reader which shows me this macro value ZXing provides...
@uwolfer That does indeed look like a bug, can you create a new issue with sample data to reproduce? Thanks!
