Is there a difference between the 'Numeric' and 'numeric' module?
I have on my system only Numeric... And this has no function like 
'from_image'.

The usual way of doing such things is to use PIL (Python Image Library) 
to load the image from file, then export it from PIL to a Python string 
in order to import from this string to an array of the targeted 
numerical module.

Really curious if there is a direct way in any of the numerical 
packages, as it would save the time and effort of unnecessary 
conversions from PIL, ImageMagick or from other image libraries.
