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 correspond 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 corresponding to that square, and its
       red, green, and blue components (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 (PseudoColor,
       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.
