Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

Syntax

js
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

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