Fonts to write barcodes:
- Libre Barcode 39
- Libre Barcode 39 Text
- Libre Barcode Extended 39
- Libre Barcode Extended 39 Text
To use these wrap the text to encode into * asterisks e.g.: *HELLO WORLD*
See the Wikipedia Code 39 page for more info.
- Libre Barcode 128
- Libre Barcode 128 Text
To use these you have to use an encoder like this (see also #14).
See the Wikipedia Code 128 page for more info.
You'll need git, bash, python3.6, node(=nodejs e.g. v10.16.3 is confirmed to work, use nvm to manage node versions) with npm, bower and ttfautohint (if not in your distribution I suggest: ttfautohint-build). Maybe you'll have to install the python3-venv module.
Are dependencies missing? Please, let me know.
