    Default Convert color image to black and white

    Is there a way using Graphics Library to convert a color image to black and white.
    The GDI+ seems can do some color tranformation, but it is not in the Graphics Library.

    Thanks.
    Kind regards,

    John,

    Indeed the ImageAttributes class needed for a transformation via a 5x5 matrix is missing from the library.
