draw_sprite_v_flip(3alleg4)					  Allegro manual				       draw_sprite_v_flip(3alleg4)

NAME
       draw_sprite_v_flip, draw_sprite_h_flip, draw_sprite_vh_flip - Draws the sprite transformed to the destination bitmap. Allegro game program-
       ming library.

SYNOPSIS
       #include <allegro.h>

       void draw_sprite_v_flip(BITMAP *bmp, BITMAP *sprite, int x, int y);

       void draw_sprite_h_flip(BITMAP *bmp, BITMAP *sprite, int x, int y);

       void draw_sprite_vh_flip(BITMAP *bmp, BITMAP *sprite, int x, int y);

DESCRIPTION
       These are like draw_sprite(), but they additionally flip the image vertically, horizontally, or	both,  respectively.  Flipping	vertically
       means  that  the y-axis is reversed, while flipping horizontally means that the x-axis is reversed, between the source and the destination.
       This produces exact mirror images, which is not the same as rotating the sprite (and it is a lot faster than  the  rotation  routine).  The
       sprite must be a memory bitmap. Example:

	  if (key[KEY_RIGHT])
	     draw_sprite(screen, hero_right, pos_x, pos_y);
	  else if (key[KEY_LEFT])
	     draw_sprite_h_flip(screen, hero_right, pos_x, pos_y);
	  else
	     draw_sprite(screen, hero_idle, pos_x, pos_y);
