Hi...
Sorry for the long delay.
These convertions in python among data and image representation indeed require
some experimentation.
(In my todo list, wiht low priority, I have a python module that would
seamlessly translate image data across various image handling
bindings/ibraries and numerical types).
Fortunatey, in this case it is rather simple:
For numpy.array -> python image, you do something like:
a = numpy.array ("\x0" (WIDTH * HEIGHT * 3), "B")
#code to create imag data inside array
# (...)
i = Image.new("RGB", (WIDTH, HEIGHT))
i.fromstring(a.tostring())
i.save(filename)
