CanvasSurface

CanvasSurface is a facade returned by registerSurface(). Apps should not construct it.

const surface = runtime.registerSurface(element, {
  bounds: { x: 24, y: 32, width: 360, height: 220 }
});

Surface API

• element
• isDisposed
• getBounds()
• setBounds(bounds)
• dispose()

Surface bounds are CSS pixels. Use setBounds() when layout changes; do not reach into backend or native implementation details.

surface.setBounds({ x: 48, y: 64, width: 420, height: 240 });
surface.dispose();

Disposing a surface unregisters it from the runtime and restores Prism-owned DOM state.
