Ink: requestPresenter() method

Limited availability

The requestPresenter() method of the Ink interface returns a Promise that fulfills with a DelegatedInkTrailPresenter object to handle rendering strokes.

Syntax

requestPresenter(param)

Parameters

• param Optional
  • : An object that contains the following property:
    • presentationArea Optional
      • : An Element inside which rendering of ink strokes is confined (the element’s border box, to be precise). If param is not included, or presentationArea is set to null, ink rendering is confined to the containing viewport by default.

Return value

A Promise that resolves to a DelegatedInkTrailPresenter object instance.

Exceptions

• Error DOMException
  • : An error is thrown and the operation is aborted if presentationArea is not a valid Element, or is not in the same document as the associated Ink object.

Example

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

  // …
}
