  /**
   * @param id A canvas must have an id, and it must be an http(s) URI. The canvas’s JSON representation should be
   * published at that URI.
   * @param label A canvas must have a label, and it should be the page or view label such as “p. 1”, “front”, or “north
   * view”.
   * @param height The height of a canvas or image resource. For images, this is in pixels. No particular units are
   * required for canvases, as the dimensions provide an aspect ratio for the resources to be located within rather than
   * measuring any physical property of the object. A canvas must have a height, which does not have a unit type. It
   * merely conveys, along with width, an aspect ratio.
   * @param width The width of a canvas or image resource. For images, this is in pixels. No particular units are
   * required for canvases. A canvas must have a height, which does not have a unit type. It merely conveys, along with
   * width, an aspect ratio.
   * @param thumbnail A canvas may have a thumbnail and should have a thumbnail if there are multiple images or
   * resources that make up the representation.
