    :param boolean useCache: whether the image should be saved/loaded using the cache. Defaults to ``true``. Reading images from a file is slow. Setting ``useCache`` to ``true`` will save the image to memory so that the next time the filepath is encountered the image can be loaded from memory rather than the file.

    Creates an image item on the specified overlay layer. This differs from ``map.addImage`` by allowing the new image to be a transformation of the image file.
 
    :param number x: the x pixel coordinate of the image's top-left corner (relative to the layer's position)

-   :param number width: the image width. If ``-1``, use the full width of the original image. Defaults to ``-1``

-   :param boolean yflip: whether the image should be a vertical flip of the original image. Defaults to ``false``

    :param number paletteId: the id of which currently loaded tileset palette to use for the image. If ``-1``, use the original image's palette. Defaults to ``-1``
