# Showcase

The full XWUIBarcodeITF14 range on one screen: 13-digit codes with a derived check digit next to explicit 14-digit codes, what the packaging indicator digit does, bar geometry sized for corrugated printing, and every knob on the human-readable digit line.

It closes with a shipping carton 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.
