NAME¶
gpolymarker - Otput primitive to draw selected symmetric symbols
SYNOPSIS¶
#include <ncarg/gks.h>
void gpolymarker(const Gpoint_list *point_list);
DESCRIPTION¶
The polymarker output primitive draws selected symmetric symbols to mark
user-specified coordinate positions.
- point_list.num_points
- (Gint, Input) - The number of markers to be drawn. Must be greater than
zero.
- point_list.points
- (Gpoint *, Input) - The X and Y coordinates of the point_list.num_points
markers to be drawn, in world coordinates.
USAGE¶
By default, the polymarker type is an asterisk. To select other polymarker types
and attributes, see the man page for gset_marker_type(3NCARG).
Note that the coordinate pairs must be in world coordinates and not user
coordinates. Among other things, this means that the log scaling and
mirror-imaging features available via the c_set call and the SPPS functions
for drawing dots and markers are not applicable here.
ACCESS¶
To use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries.
