NAME

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

SYNOPSIS

       CALL GQCR (WKID, CI, TYPE, ERRIND, CR, CG, CB)

C-BINDING 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

       WKID        (Integer, Input) - Gives a workstation identifier as was set in a previous call to GOPWK.

       CI          (Integer, Input) - A color index.

       TYPE        (Integer, Input) - Specifies whether the  returned  color  values  are  the  ones  that  were
                   specified by a call to GSCR 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).

                   0      Returns the color value set for index CI either by default or by a call to GSCR.

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

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

       CR          (Real, Output) - Returns an intensity value for red in the range 0. to 1. inclusive.

       CG          (Real, Output) - Returns an intensity value for green in the range 0. to 1. inclusive.

       CB          (Real, 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 GSCR.
