Consult "User's Guide for NCAR GKS-0A Graphics" for a description of the meaning of the error indicators. .IP colr_rep.rgb.red 12 (Gfloat, Output) - Returns an intensity value for red in the range 0. to 1. inclusive. .IP colr_rep.rgb.green 12 (Gfloat, Output) - Returns an intensity value for green in the range 0. to 1. inclusive. .IP colr_rep.rgb.blue 12 (Gfloat, Output) - Returns an intensity value for blue in the range 0. to 1. inclusive. .SH USAGE For details on setting and using color indices see the man page for gset_colr_rep. .SH ACCESS To use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries. .SH SEE ALSO Online: .BR gset_colr_rep(3NCARG), .BR gset_line_colr_ind(3NCARG), .BR gset_marker_size(3NCARG), .BR gset_text_colr_ind(3NCARG), .BR gset_fill_colr_ind(3NCARG), .BR gks(3NCARG), .BR ncarg_gks_cbind(3NCARG) .sp Hardcopy: User's Guide for NCAR GKS-0A Graphics; NCAR Graphics Fundamentals, UNIX Version .SH COPYRIGHT Copyright (C) 1987-2009 .br University Corporation for Atmospheric Research .br The use of this Software is governed by a License Agreement.
