NAME

       al_draw_rotated_bitmap - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_draw_rotated_bitmap(ALLEGRO_BITMAP *bitmap,
                 float cx, float cy, float dx, float dy, float angle, int flags)

DESCRIPTION

       Draws  a  rotated version of the given bitmap to the target bitmap.  The bitmap is rotated
       by 'angle' radians clockwise.

       The point at cx/cy relative to the upper left corner of the bitmap will be drawn at  dx/dy
       and  the  bitmap  is  rotated  around  this point.  If cx,cy is 0,0 the bitmap will rotate
       around its upper left corner.

       • cx - center x (relative to the bitmap)

       • cy - center y (relative to the bitmap)

       • dx - destination x

       • dy - destination y

       • angle - angle by which to rotate (radians)

       • flags - same as for al_draw_bitmap(3alleg5)

       Example

              float w = al_get_bitmap_width(bitmap);
              float h = al_get_bitmap_height(bitmap);
              al_draw_rotated_bitmap(bitmap, w / 2, h / 2, x, y, ALLEGRO_PI / 2, 0);

       The above code draws the bitmap centered on x/y and rotates it 90° clockwise.

       See al_draw_bitmap(3alleg5) for a note on restrictions  on  which  bitmaps  can  be  drawn
       where.
