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.
