Generating Code128A

[judylin1]

I have an existing barcode encoded in Code128A with text "12ABC456". I don't think parse or parsefnc is necessary, but even testing with / without those, the barcode does not match my existing one. Is there a way to force a CODE128A barcode to be generated?

For reference, the barcode I have looks like the attached barcode.

The one generated by bwip looks like this:

BWIPP only supports two encoding methods for code128 - raw and auto - and there is no way to force the encoder to use only subset A.

Is there a reason why only subset A can be used?

If you can guarantee that the text to encode will always be subset A characters, it is not hard to generate the raw encoding. As a reference, see the code128 wikipedia page.

The following issue represents the current status of fixed-mode support in the underlying BWIPP library:

This linked workaround should be sufficient to generate your required Code 128A:

Encoder: code128
Data: ^103^017^018^033^034^035^020^021^022
Options: raw

Representing:

[Start A] [1] [2] [A] [B] [C] [4] [5] [6]
