NAME

       rotate_sprite - Rotates a sprite. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void rotate_sprite(BITMAP *bmp, BITMAP *sprite, int x, int y, fixed angle);

DESCRIPTION

       Draws  the  sprite  image  onto	the bitmap. It is placed with its top left corner at the specified position, then rotated by the specified
       angle around its centre. The angle is a fixed point 16.16 number in the same format used by the fixed point trig routines, with	256  equal
       to a full circle, 64 a right angle, etc. All rotation functions can draw between any two bitmaps, even screen bitmaps or bitmaps of differ-
       ent color depth.

       Positive increments of the angle will make the sprite rotate clockwise on the screen, as demonstrated by the Allegro example.
