SYNOPSISCALL 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);
- (Integer, Input) - Gives a workstation identifier as was set in a previous call to GOPWK.
- (Integer, Input) - A color index.
(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).
- Returns the color value set for index CI either by default or by a call to GSCR.
- Returns the color value actually used by the workstation to represent the requested color.
- (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.
- (Real, Output) - Returns an intensity value for red in the range 0. to 1. inclusive.
- (Real, Output) - Returns an intensity value for green in the range 0. to 1. inclusive.
- (Real, Output) - Returns an intensity value for blue in the range 0. to 1. inclusive.
