xstdcmap(1)


NAME

   xstdcmap - X standard colormap utility

SYNOPSIS

   xstdcmap  [-all]  [-best]  [-blue]  [-default]  [-delete map] [-display
   display] [-gray] [-green] [-help] [-red] [-verbose] [-version]

DESCRIPTION

   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.

OPTIONS

   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.

   -version
           This option indicates that xstdcmap should  print  its  version
           and exit.

ENVIRONMENT

   DISPLAY to get default host and display number.
