        and the palette can be represented without a palette.

        This supports all possible conversions between "L", "RGB" and "CMYK". The
        ``matrix`` argument only supports "L" and "RGB".

        When translating a color image to grayscale (mode "L"),

            L = R * 299/1000 + G * 587/1000 + B * 114/1000

        The default method of converting a grayscale ("L") or "RGB"
        image into a bilevel (mode "1") image uses Floyd-Steinberg
        dither to approximate the original image luminosity levels. If
        dither is ``None``, all values larger than 127 are set to 255 (white),
        all other values to 0 (black). To use other thresholds, use the
        :py:meth:`~PIL.Image.Image.point` method.

        When converting from "RGBA" to "P" without a ``matrix`` argument,
        this passes the operation to :py:meth:`~PIL.Image.Image.quantize`,
        and ``dither`` and ``palette`` are ignored.

        When converting from "PA", if an "RGBA" palette is present, the alpha
        channel from the image will be used instead of the values from the palette.

        :param mode: The requested mode. See: :ref:`concept-modes`.
        :param matrix: An optional conversion matrix.  If given, this

        :param dither: Dithering method, used when converting from

           Available methods are :data:`Dither.NONE` or :data:`Dither.FLOYDSTEINBERG`
           (default). Note that this is not used when ``matrix`` is supplied.
