al_draw_rotated_bitmap(3) al_draw_rotated_bitmap(3) NAME al_draw_rotated_bitmap - Allegro 5 API SYNOPSIS #include 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. o cx - center x (relative to the bitmap) o cy - center y (relative to the bitmap) o dx - destination x o dy - destination y o angle - angle by which to rotate (radians) o 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 90 clockwise. See al_draw_bitmap(3) for a note on restrictions on which bitmaps can be drawn where.
