Passing negative values to clip for an N.uint8 array causes problems:
In [95]: z.clip(0,100).max()
Out[95]: 100
In [96]: z = (N.random.random(1000)*128).astype(N.uint8)
In [97]: z.clip(0,100).max()
Out[97]: 100
In [98]: z = (N.random.random(1000)*128).astype(N.uint8)
In [99]: z.clip(-10,100).max()
Out[99]: 246
Cheers
Stéfan
