NAME
cmap_alloc - allocate default colormaps for non-default visuals
SYNOPSIS
/usr/bin/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 XGetRGBColormaps(3x11) 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
Create default colormaps for all screens of the display.
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
