+   *     For simple cases, you may also send a string (the URL or filename of

+   * @param {object} request.image A dictionary-like object representing the

+   *     If the key is `source`, the value should be another object containing

+   *     If the key is `content`, the value should be a Buffer.

+   * @param {function(?Error, ?object)} [callback] The function which will be

+   *     The second parameter to the callback is an object representing
