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

11
12 void ginq_colr_rep(Gint ws_id, Gint colr_ind, Ginq_type type, Gint
13 *err_ind, Gcolr_rep *colr_rep);
14
16 ws_id (Input) - Gives a workstation identifier as was set in a
17 previous call to gopen_ws.
18
19 colr_ind (Input) - A color index.
20
21 type (Input) - Specifies whether the returned color values are
22 the ones that were specified by a call to gset_colr_rep or
23 whether they are the color values that are actually being
24 used on the specified workstation (frequently a workstation
25 will not be able to represent a requested color value pre‐
26 cisely).
27
28 GINQ_SET
29 Returns the color value set for index colr_ind
30 either by default or by a call to gset_colr_rep.
31
32 GINQ_REALIZED
33 Returns the color value actually used by the work‐
34 station to represent the requested color.
35
36 err_ind (Output) - If the inquired values cannot be returned cor‐
37 rectly, a non-zero error indicator is returned in err_ind,
38 otherwise a zero is returned. Consult "User's Guide for
39 NCAR GKS-0A Graphics" for a description of the meaning of
40 the error indicators.
41
42 colr_rep.rgb.red
43 (Gfloat, Output) - Returns an intensity value for red in
44 the range 0. to 1. inclusive.
45
46 colr_rep.rgb.green
47 (Gfloat, Output) - Returns an intensity value for green in
48 the range 0. to 1. inclusive.
49
50 colr_rep.rgb.blue
51 (Gfloat, Output) - Returns an intensity value for blue in
52 the range 0. to 1. inclusive.
53
55 For details on setting and using color indices see the man page for
56 gset_colr_rep.

59 To use the GKS C-binding routines, load the ncarg_gks and ncarg_c
60 libraries.
