I have got the pixel value of an image patch as the following shows, but how should I show them as an image patch by using python? Is there a method in the PIL library?

array([[162, 162, 161, 162, 156, 163, 160],
       [162, 162, 161, 162, 156, 163, 160],
       [162, 162, 161, 162, 156, 163, 160],
       [162, 162, 161, 162, 156, 163, 160],
       [162, 162, 161, 162, 156, 163, 160],
       [164, 157, 155, 161, 159, 158, 159],
       [160, 163, 158, 160, 161, 159, 155]])

transform an image to an array can use np.array(img.getdata()), then how to transform an array to an image? – Ryuka Mar 10 '13 at 13:32
Maybe imread() and imshow() in matplotlib is more convenient. – Ryuka Mar 10 '13 at 14:29
