Hi, I have trouble in pow operation for images. I have the 
following error. Thanks in advance.




print A.format, A.size, A.mode

TIFF (508, 807) RGB


import ImageMath


>>> Alin = A ** 2




Traceback (most recent call last):


File "<pyshell#37>", line 1, in <module>


Alin = A ** 2


TypeError: unsupported operand type(s) for ** or pow(): 'instance' and 'int'
