In this example we will print an identicon and a barcode for each label.

This example shows:

• How to use label_tools.barcode
• How to transform a picture generated on-the-fly into base64 data so it can be integrated into a <img/> tag.
• How to define extra variables or functions and use them from inside the template (here, generate_identicon).

This example requires pydenticon installed:

pip install pydenticon
