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 associ-
ated 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 col-
ormap 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 col-
ormaps for visuals of all depths
-visual class
Create default colormaps only for those visuals
that are of class class. Where class is one of
the following: GrayScale, PsuedoColor, DirectColor
-verbose Print out diagnostic messages useful for debug-
ging.
-help Print out a short usage message and exit.
