DelegatedInkTrailPresenter: presentationArea property

Limited availability

The presentationArea read-only property of the DelegatedInkTrailPresenter interface returns the Element inside which rendering of ink strokes is confined.

If the preceding Ink.requestPresenter() method call included a specific presentationArea element definition, then that will be the element returned. Otherwise, the default is returned, which is the containing viewport.

This area is always the client coordinates for the element’s border box, so moving the element or scrolling the element requires no recalculation on the developer’s part.

Value

An Element.

Example

async function inkInit() {
  const ink = navigator.ink;
  const presenter = await ink.requestPresenter({ presentationArea: canvas });
  console.log(presenter.presentationArea);

  // …
}
