RETURN VALUE

The palette xvobject on success, NULL otherwise

DESCRIPTION

The palette visual object provides a visual display of the colors defined by a colormap. The colors may be displayed as a grid of color cells, a color palette, or a color wheel.

Note that when an RGB image is displayed on an 8-bit screen, a 3-3-2 transformation is used in order to convert the RGB image into an 8-bit representation. Because of this, the colors in the palette object that are displayed in this situation will reflect the 3-3-2 map, and may not seem to correspond to the displayed image.
