al_draw_ribbon - Allegro 5 API

#include <allegro5/allegro_primitives.h>
void al_draw_ribbon(const float *points, int points_stride, ALLEGRO_COLOR color,
   float thickness, int num_segments)

Draws a ribbon given an array of points. The ribbon will go through all of the passed points. The points buffer should consist of regularly spaced doublets of floats, corresponding to x and y coordinates of the vertices.


points - An array of coordinate pairs (x and y) for each point
points_stride - Distance (in bytes) between starts of successive pairs of coordinates in the points buffer
color - Color of the spline
thickness - Thickness of the spline, pass <= 0 to draw hairline spline
num_segments - The number of segments
