al_calculate_ribbon(3)					al_calculate_ribbon(3)

NAME
       al_calculate_ribbon - Allegro 5 API

SYNOPSIS
	      #include <allegro5/allegro_primitives.h>

	      void al_calculate_ribbon(float* dest, int	dest_stride, const float *points,
		 int points_stride, float thickness, int num_segments)

DESCRIPTION
       Calculates  a  ribbon  given  an	 array	of points.  The	ribbon will go
       through all of the passed points.  If thickness <= 0, then num_segments
       of  points  are	required in the	destination buffer, otherwise twice as
       many are	needed.	 The destination and the points	buffer should  consist
       of  regularly spaced doublets of	floats,	corresponding to x and y coor-
       dinates of the vertices.

       Parameters:

       o dest -	Pointer	to the destination buffer

       o dest_stride - Distance	(in bytes) between starts of successive	 pairs
	 of coordinates	in the destination buffer

       o points	- An array of pairs of coordinates for each point

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

       o thickness - Thickness of the spline ribbon

       o num_segments -	The number of points to	calculate
