# Showcase

The full XWUIBarcodeDataMatrix range on one screen: ECC200 payloads (part numbers, URLs, packed digit runs, Latin-1 text), pixel sizing, the module-measured quiet zone, and how the symbol grid grows as capacity is consumed.

It closes with a direct part marking label and a re-encode plus `getDataURL()` export, since this component has no `setData()`: rotating a payload means `destroy()` then a fresh instance. Modules stay black on white because scanner contrast is a hard requirement, so the canvas ink is deliberately not themed.
