# Showcase

The full XWUIBarcodeITF range on one screen: the digit-pair rule behind Interleaved 2 of 5 (including the automatic leading zero for an odd digit count), payload length, bar geometry (module width, height, quiet zone), and every knob on the human-readable digit line.

It closes with a warehouse carton case label and a live re-encode driven by `setData()`. Bars stay black on white because scanner contrast is a hard requirement, so the canvas ink is deliberately not themed.
