NAME
       cmap_alloc - allocate default colormaps for non-default visuals

SYNOPSIS
       cmap_alloc  [  -display display:n.screen ] [ -force ] [ -allscreens ] [
       -depth n ] [ -visual class ] [ -verbose ] [ -help ]

DESCRIPTION
       cmap_alloc creates empty colormaps for non-default dynamic visuals that
       are  suitable for use as default colormaps.  An X11 server has only one
       default colormap,  and  it  is  associated  with	 the  default  visual.
       Clients	that  need  to access non-default visuals have to create their
       own colormaps.  This can lead to gratuitous colormap flashing if a  lot
       of  applications	 are  running in non-default visuals.  cmap_alloc will
       create colormaps that can be used by such applications as  the  default
       colormap	 for the given visual.	Once the colormap has been created for
       a  given	 visual,  it  will  place  the	 colormap's   XID   into   the
       RGB_DEFAULT_MAP	property  on  the root window of the display.  Clients
       that need to access non-default	dynamic	 visuals  should  search  this
       property using XGetRBGColormaps() for a suitable colormap to use.

OPTIONS
       -display display:n.screen
		 Indicates which X11 server to use.  The default is to use the
		 value set in the DISPLAY environment variable.

       -force	 Create a colormap even if  a  suitable	 colormap  is  already
		 listed in the RGB_DEFAULT_MAP property.

       -allscreens

		 Without this option, colormaps will only be created  for  the
		 default screen.

       -depth n	 Create	 default  colormaps  only  for those visuals that have
		 depth n.  The default is to create colormaps for  visuals  of
		 all depths
