zone.py is a small program which takes as input an image, distinguishes its colour zones and can do some operations, such as:
  * paint them with new colours
  * count them (based on colour)
  * output a textual representation of them

===== Requirements =====
zone.py requires python, PIL (package python-imaging in Debian/Ubuntu) and scipy (package python-scipy in Debian/Ubuntu).

===== Usage =====
Just [[http://poisson.phc.unipi.it/~battiston/sitomio/progri/zone.py|download]] the app (license: [[http://www.gnu.org/licenses/gpl-3.0.txt|GPL 3.0]]), and run it (with "python zone.py image.ext", or "./zone.py image.ext" after making it executable).

Run it with the "--help" argument to see available options.

===== Warning =====
There is no option to modify the "threshold" value which appears in the file for the simple reason that it isn't correctly supported (it //may// do what you want, but is incoherent, e.g. can change its behaviour if you just rotate the image).

===== Examples =====
This image (a picture of me kissing a scanner):

{{:zone.py_io.jpg?400|Me on a scanner}}

became the following:

{{:zone.py_io_fuori.png?400|Me on a scanner}}{{:zone.py_io_fuori_rand.png?400|Me on a scanner}}
