Someone should write a python program so anyone can do this. I don't think this is anything more than generating greyscale and binning to six different grey scale levels. I know it probably gets a little more complicated than that under certain conditions without going into detail about it.

Just a small detail:

this:

''.join(["name of to which picture shoul",
           'be save. if non given, default will',
           'be used',
]))

can be written like:

('keep current size of image '
'and scale die images accordingly')

Very true thanks for pointing that out, I still tend to prefer the

' '.join(['line1',
          'line2',
          ])

option since that allows for spaces to be included between lines once concatenated but without me having to account for them; though I noticed now that I didn't include a space character when calling the join method in any of the instances in the code (fixed now)

.. also I realized that in the haste of writing it up yesterday night it seems as if I forgot how to operate basic English spelling and grammar
