xcmap(1X)

NAME
       xcmap - displays the default colormap on X11 displays

SYNTAX
       xcmap [ [-d] display] [ [-g] geometry]

DESCRIPTION
       xcmap  is an X11 program that displays the contents of the
       colormap on 4, 6, and  8-bit  PseudoColor  (or  GreyScale)
       displays.   It  displays  a grid of squares, (4x4, 8x8, or
       16x16 grid, depending on the number of planes) that corre-
       spond  to  entries  in  the colormap.  The squares are (of
       course) drawn in their corresponding color.

       You may click (with the  left  button)  on  any  of  these
       squares.   Doing  so  will display the pixel number corre-
       sponding to that square, and its red, green, and blue com-
       ponents  (as 4-digit hex numbers).  It will continue to do
       this as long as you hold the button down.

BUGS
       This program only works on colormapped  displays  (Pseudo-
       Color,  GreyScale,  StaticColor,  and StaticGrey visuals).
       Running it on a display that has a default visual type  of
       'TrueColor' or 'DirectColor' will do nothing of value, and
       may or may not work at all.

       Also, this program only works on 4, 6, and 8-bit displays.
       Period.
