Is it possible to draw that kind of barcode?

For now I think that Code-128 auto charset is only option.

Best regards
Davor.

Hi!

I've read in the online-reference:

It's a combination of 128 B and C - not real 128 B.

Cheers, Ingo

The auto option will work perfectly fine. Code 128 actually includes A,B and C version. A is not used much, B is for alpahnumeric characters and C is for numeric only. The version used changes automatically depending on the characters in the string. The code can change automatically from B to C and back again.

If you have 4 or more numbers (digits 0 - 9) then the code will switch to C. It will switch back to B if an alpha character is used.

123456 - uses CCCCCC

AB1234 - uses BBCCCC

A1B2C3 - uses BBBBBB

HELLO3 - uses BBBBBB

A1234B - uses BCCCCB

Thanks Ingo, Andrew.
Both of you are right.

But the documentation by which I work says that Code-128 type B must be used. :(
Currently, neither the creator of that documentation doesn't use Code-128 type B, they use AUTO.

So for now, I'm OK, but who knows how long.
It would be nice to have option in case they change barcode type.

Once again thank you all.

Greetings from Croatia.
