And by the way, if I take away the 913-shift-to-octet patch, which is essentially the version in the BarcodeTest.zip posted on Nov. 16, the barcode generated can be readily accepted by http://online-barcode-reader.inliteresearch.com/. In its UTF version, exact same string is displayed. We can do without the 913-shift thing to be safe. All type of data will be properly encoded, only the encoding might not be optimum.

Here is a more authoritative reference:
http://www.expresscorp.com/content/express/pdf/IndustrySpeci fications/USS-PDF-417.pdf

Turns out 913 can only be used within Text Mode to shift to byte compaction for the next codeword, and then the original Text submode is restored. I don't see a reason why 913-shift is not allowed in Numeric context, but according the the standard, barcode for this text ( ABCDEFâABCDEFGHIJKL) is correct even though most online decoders don't recognize it. And barcode associated with this text (0123456789012A0123456789012) is indeed invalid.

I have added Truncated pdf417 and some other functionalities. In order not to waste too much resources, I'll just keep it. Maybe until I at least make some progress on QR code.

HI there
Thanks for your barcode sharing.I am exactly looking a free online barcode generator.I hope it is possible for my barcode generator to generate code 128 and upc-a at the same time.Is that ok?

Hi there,
if someone download this library and has issues compiling it, namely the following error:

Barcode\Code128.cpp(701): error C2280: 'Upp::Vector<Upp::byte> &Upp::Vector<Upp::byte>::operator =(const Upp::Vector<Upp::byte> &)': trying to reference a deleted function


you have to read here to fix it.
Regards,
Gio
