do_ellipse(3)			 Allegro manual 		   do_ellipse(3)

NAME
     do_ellipse - Calculates all the points in an ellipse. Allegro game program-
     ming library.

SYNOPSIS
     #include <allegro.h>

     void  do_ellipse(BITMAP  *bmp,  int  x,  int  y,  int  rx,  ry, int d, void
     (*proc)(BITMAP *bmp, int x, int y, int d));

DESCRIPTION
     Calculates all the points in an ellipse around point (x, y) with radius  rx
     and  ry,  calling the supplied function for each one. This will be passed a
     copy of the bmp parameter, the x and y position, and a copy of the d  para-
     meter, so it is suitable for use with putpixel(). Example:

	void draw_explosion_ring(BITMAP *bmp, int x, int y, int d)
	{
	   ...
	}

	   do_ellipse(screen, SCREEN_W/2, SCREEN_H/2,
		     SCREEN_H/16, SCREEN_H/32, flame_color,
		     draw_explosion_ring);
