Barcodes can't be generated in required formats

[mrst]

I have a use case where I need to digitize an ITF (Interleaved 2 of 5) Barcode (which can be read by the glide barcode scanner) and show a digital representation of that barcode for the scanner in the real world where I can't expect another format to be accepted and can't change the reader terminal.

This is why I would like to generate the barcode in the same format as it was scanned so I don't need to take a picture of it and hope that the contrast is high enough on the photo to be scanned again later on.

Luckily the generator library already supports all the different formats supported by the reader and even more, so it's only a matter of accepting the format.
