xstdcmap - X standard colormap utility
xstdcmap [-all] [-best] [-blue] [-default] [-delete map] [-display display] [-gray] [-green] [-help] [-red] [-verbose]
The xstdcmap utility can be used to selectively define standard colormap 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 possible, 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 colormap 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. -default This option indicates that the RGB_DEFAULT_MAP should be defined. -delete map This option specifies that a specific standard colormap property, or all such properties, should be removed. map may be one of: default, best, red, green, blue, gray, or all. -display display 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 xstdcmap. -red This option indicates that the RGB_RED_MAP should be defined. -verbose This option indicates that xstdcmap should print logging information as it parses its input and defines the standard colormap properties.
DISPLAY to get default host and display number.
