Description:

Python implementation of the Sane API (using ctypes) and abstration layer.
The code is divided in 3 layers:

rawapi : Ctypes binding to the raw Sane API
abstract : An Object-Oriented layer that simplifies the use of the Sane API
and try to avoid possible misuse of the Sane API. When scanning,
it also takes care of returning a PIL image.
abstract_th : The Sane API is not thread-safe and cannot be used in a
multi-threaded environment easily.
This layer solves this problem but using a fully dedicated thread.
