  * @property {null|string} [crossOrigin] The `crossOrigin` attribute for loaded images.  Note that
  * you must provide a `crossOrigin` value if you want to access pixel data with the Canvas renderer.
  * See https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image for more detail.
+ * @property {boolean} [imageSmoothing=true] Enable image smoothing.
  * @property {boolean} [opaque=true] Whether the layer is opaque.
  * @property {import("../proj.js").ProjectionLike} [projection] Projection. Default is the view projection.
  * @property {number} [reprojectionErrorThreshold=0.5] Maximum allowed reprojection error (in pixels).
  * Higher values can increase reprojection performance, but decrease precision.
- * @property {object} [reprojectionContextOptions] Optional properties to set on the canvas context used
- * for reprojection. For example specify `{imageSmoothingEnabled: false}` to disable image smoothing.
  * @property {import("./State.js").default} [state] Source state.
  * @property {typeof import("../ImageTile.js").default} [tileClass] Class used to instantiate image tiles.
  * Default is {@link module:ol/ImageTile~ImageTile}.
