Have you looked at the BWIPP reference for codabar? bwip-js is essentially a wrapper around BWIPP.

I need to review the source for the built-in drawing modules. There is common core code used by both the html canvas interface and node that would be impacted by...

I think it best to punt on this issue for right now. Changing the built-in drawing code is problematic as it has no a priori knowledge of color depth. Conversely,...

I think you are misunderstanding the issue. The actual code to produce a gray scale png is not difficult. The issue is knowing when it is safe to do so....

I assume you mean the `gs1datamatrix` encoder. According to: https://www.gs1.org/standards/barcodes/application-identifiers/21?lang=en Parentheses (0x28, 0x29) are legal in serial numbers. It may not be what you expect, but it is correct.

It was not clear in your original post that an error was occurring. I tried your malformed string in the online BWIPP demo, and it is giving a similar type...

@akucherov: Since this isn't resolved yet, you may want to consider using the general datamatrix encoder and manually create the GS1 format. From the BWIPP reference at: https://github.com/bwipp/postscriptbarcode/wiki/Data-Matrix Use encoder...

@terryburton: The error is occurring in the postscript code. The code does a `get` on the `fncvals` dict using the 4 characters after the `^` (i.e. `076^`). This generates an...

That seems reasonable. And gives the caller an idea of what they did wrong. @semireg: The reason your input is incorrect is when the `parsefnc` flag is set, you must...

Please show the options/values used in bwip-js to generate the barcode.
