To obtain the graph of the function $$y= \sqrt {2}\cos x$$, it is only necessary to stretch the x-coordinates of all points on the graph of the function $$y= \sqrt {2}\sin(2x+ \frac {\pi}{4})$$ by a factor of \_\_\_\_\_\_, (keeping the y-coordinates unchanged), and then move it parallelly by \_\_\_\_\_\_ units to the \_\_\_\_\_\_ to get it.
