NAME
       GSCR (Set color representation) - associates a color value with a color index.


SYNOPSIS
       CALL GSCR (WKID, CI, CR, CG, CB)


C-BINDING SYNOPSIS
       #include <ncarg/gks.h>

       void gset_colr_rep(Gint ws_id, Gint colr_ind, const Gcolr_rep *colr_rep);


DESCRIPTION
       WKID        (Integer,  Input)  -  A  workstation  identifier.  WKID must be the same as that used in some
                   previous GOPWK call.

       CI          (Integer, Input) - A color index.

       CR          (Real, Input) - An intensity value for red between 0. and 1. inclusive.

       CG          (Real, Input) - An intensity value for green between 0. and 1. inclusive.

       CB          (Real, Input) - An intensity value for blue between 0. and 1. inclusive.


USAGE
       Color in GKS is "indexed", i.e. color attributes are assigned to primitives by using a color index.   The
       GKS function GSCR is used to associate a color value with color indices.

       It  is   recommended  that  all  color indices used in a given job be defined prior to calling any output
       primitive.  Since the result of a dynamic color change can be ambiguous, it is also recommended that GSCR
       not be called to change a color value after the original definitions.

       GSCR may be called after opening the workstation for which the color indices are to be defined,  and  not
       before  that workstation is opened.  Different color tables can be maintained for different workstations.
       For example, color index 2 for a CGM file may be associated with "red" while at the same time it  may  be
       associated with "green" for some X workstation.

       It  is  important  to  stress  that  color index 0 defines the background color. If any color indices are
       defined, then you should define the background color index 0. Otherwise you run  the  risk  of  having  a
       user-defined color match the default background color.

       For  all  GKS  output primitives, color is assigned by an indexing scheme. The indices run from 0 to 255,
       where 0 is the background color index and 1 is the foreground color index.


ACCESS
       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
