al_draw_rotated_bitmap(3)   Library Functions Manual   al_draw_rotated_bitmap(3)

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(3)

     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  90A<degree>
     clockwise.

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