NAME

       ginq_colr_rep - Inquire GKS color representation

DESCRIPTION

       ginq_colr_rep (Inquire color representation) - retrieves the color value associated with a color index on
       a particular workstation.

SYNOPSIS

       #include <ncarg/gks.h>

       void ginq_colr_rep(Gint ws_id, Gint colr_ind, Ginq_type type, Gint *err_ind, Gcolr_rep  *colr_rep);

DESCRIPTION

       ws_id       (Input) - Gives a workstation identifier as was set in a previous call to gopen_ws.

       colr_ind    (Input) - A color index.

       type        (Input)  -  Specifies whether the returned color values are the ones that were specified by a
                   call to gset_colr_rep or whether they are the color values that are actually  being  used  on
                   the specified workstation (frequently a workstation will not be able to represent a requested
                   color value precisely).

                   GINQ_SET
                          Returns  the  color  value  set  for  index colr_ind either by default or by a call to
                          gset_colr_rep.

                   GINQ_REALIZED
                          Returns the color value actually used by the workstation to  represent  the  requested
                          color.

       err_ind     (Output) - If the inquired values cannot be returned correctly, a non-zero error indicator is
                   returned  in  err_ind,  otherwise  a zero is returned.  Consult "User's Guide for NCAR GKS-0A
                   Graphics" for a description of the meaning of the error indicators.

       colr_rep.rgb.red
                   (Gfloat, Output) - Returns an intensity value for red in the range 0. to 1. inclusive.

       colr_rep.rgb.green
                   (Gfloat, Output) - Returns an intensity value for green in the range 0. to 1. inclusive.

       colr_rep.rgb.blue
                   (Gfloat, Output) - Returns an intensity value for blue in the range 0. to 1. inclusive.

USAGE

       For details on setting and using color indices see the man page for gset_colr_rep.
