The mode can be one of "1", "L", "P", or "RGB". If the display requires a palette, this constructor creates a suitable palette and associates it with the image. For an "L" image, 128 greylevels are allocated. For an "RGB" image, a 6x6x6 colour cube is used, together with 20 greylevels. To make sure that palettes work properly under Windows, you must call the ``palette`` method upon certain events from Windows. :param image: Either a PIL image, or a mode string. If a mode string is used, a size must also be given. The mode can be one of "1", "L", "P", or "RGB". :param size: If the first argument is a mode string, this defines the size of the image.
