al_draw_ribbon(3)          Library Functions Manual          al_draw_ribbon(3)

NAME
       al_draw_ribbon - Allegro 5 API

SYNOPSIS
              #include <allegro5/allegro_primitives.h>

              void al_draw_ribbon(const float *points, int points_stride, ALLEGRO_COLOR color,
                 float thickness, int num_segments)

DESCRIPTION
       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.

       Parameters:

       o points - An array of coordinate pairs (x and y) for each point

       o points_stride - Distance (in bytes) between starts of successive
         pairs of coordinates in the points buffer

       o color - Color of the spline

       o thickness - Thickness of the spline, pass <= 0 to draw hairline
         spline

       o num_segments - The number of segments
