gset_line_colr_ind Polyline color index(3) sets the polyline color index.


#include <ncarg/gks.h>

void gset_line_colr_ind(Gint line_colr_ind);


(Input) - A color index.


All lines drawn with calls to the gpolyline output primitive will be drawn with the color associated with index line_colr_ind until gset_line_colr_ind is called again and a new index is assigned.

For all GKS output primitives, color is assigned using a color index. The color indices run from 0 to 255, where 0 is the background color index and 1 is the foreground color index. Color values are associated with indices by calls to the GKS routine gset_colr_rep. If a color index is used that has no user-assigned color value set in a gset_colr_rep call, then a device-dependent color value will be assigned to that index.


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