al_draw_scaled_rotated_bitmap
void al_draw_scaled_rotated_bitmap(ALLEGRO_BITMAP *bitmap,
float cx, float cy, float dx, float dy, float xscale, float yscale,
float angle, int flags)
Like al_draw_rotated_bitmap, but can also scale the bitmap.
The point at cx/cy in the bitmap will be drawn at dx/dy and the bitmap is rotated and scaled around this point.
- cx - center x
- cy - center y
- dx - destination x
- dy - destination y
- xscale - how much to scale on the x-axis (e.g. 2 for twice the size)
- yscale - how much to scale on the y-axis
- angle - angle by which to rotate
- flags - same as for al_draw_bitmap
