[SciPy-dev] should Int8 be UnsignedInt8 in misc/pilutil.py?

[Albert Huang]

Hello,

pilutil.imread currently converts RGB images to arrays of signed integers.
I think it should be unsigned integers instead.  If you do an imshow(imread(
... ) ) on any brightly colored image, then all the RGB values > 127 get
whacked.

Also, it's probably not very intuitive to say that -1 is brighter than 127.

The attached patch fixes it for me.  I just changed all occurences of 'b' to
'B', but am not too sure what the effect is in toimage().

Regards,
Albert
