xstdcmap - X standard colormap utility
xstdcmap [-all] [-best] [-blue] [-default] [-delete map] [-display dis-
play] [-gray] [-green] [-help] [-red] [-verbose] [-version]
The xstdcmap utility can be used to selectively define standard col-
ormap properties. It is intended to be run from a user's X startup
script to create standard colormap definitions in order to facilitate
sharing of scarce colormap resources among clients. Where at all pos-
sible, colormaps are created with read-only allocations.
The following options may be used with xstdcmap:
-all This option indicates that all six standard colormap properties
should be defined on each screen of the display. Not all
screens will support visuals under which all six standard col-
ormap properties are meaningful. xstdcmap will determine the
best allocations and visuals for the colormap properties of a
screen. Any previously existing standard colormap properties
will be replaced.
-best This option indicates that the RGB_BEST_MAP should be defined.
-blue This option indicates that the RGB_BLUE_MAP should be defined.
This option indicates that the RGB_DEFAULT_MAP should be
This option specifies that a specific standard colormap prop-
erty, or all such properties, should be removed. map may be
one of: default, best, red, green, blue, gray, or all.
This option specifies the host and display to use; see X(7).
-gray This option indicates that the RGB_GRAY_MAP should be defined.
-green This option indicates that the RGB_GREEN_MAP should be defined.
-help This option indicates that a brief description of the command
line arguments should be printed on the standard error. This
will be done whenever an unhandled argument is given to xstd-
-red This option indicates that the RGB_RED_MAP should be defined.
This option indicates that xstdcmap should print logging infor-
mation as it parses its input and defines the standard colormap
This option indicates that xstdcmap should print its version
