        """
        Create a new SArray with all the values cast to :py:class:`turicreate.image.Image`
        of uniform size.

        Parameters
        ----------
        width: int
            The width of the new images.

        height: int
            The height of the new images.

        channels: int.
            Number of channels of the new images.

        undefined_on_failure: bool , optional , default True
            If True, return None type instead of Image type in failure instances.
            If False, raises error upon failure.

        allow_rounding: bool, optional , default False
            If True, rounds non-integer values when converting to Image type.
            If False, raises error upon rounding.

        Returns
        -------
        out : SArray[turicreate.Image]
            The SArray converted to the type 'turicreate.Image'.

        Examples
        --------
        The MNIST data is scaled from 0 to 1, but our image type only loads integer  pixel values
        from 0 to 255. If we just convert without scaling, all values below one would be cast to
        0.
