# Showcase

The flagship XWUIChatCanvas demo: the default 480 by 320 drawing surface, size and brush presets, and the toolbar options (custom palette, swatch row hidden, read-only viewer). It then covers the two image inputs, a permanent backgroundImage backdrop that survives Clear versus a one-time initialImage draft, and finishes with a live pad wired to the whole programmatic API (setTool, setColor, setBrushSize, undo, clear, isEmpty, toDataURL, toBlob) and the onStroke, onSend and onCancel events.
