Ink: requestPresenter() method

{{APIRef("Ink API")}}{{SeeCompatTable}}

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

Syntax

requestPresenter(param)

Parameters

• param {{optional_inline}}
  • : An object that contains the following property:
    • presentationArea {{optional_inline}}
      • : An {{domxref("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 {{jsxref("Promise")}} that resolves to a {{domxref("DelegatedInkTrailPresenter")}} object instance.

Exceptions

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

Example

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

  // …
}
