NAME

       draw_sprite_v_flip,  draw_sprite_h_flip,  draw_sprite_vh_flip  -  Draws  the  sprite  transformed  to the
       destination bitmap. Allegro game programming 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);
