Introduction

The python-imagescanner (old pyscanning) implements an abstraction layer which allows users to scan images/documents from Linux or Windows without the need of write any specific Python code for each one of them.

Supported Devices

All devices supported by SANE (Linux) and Twain (Windows). If you are able to use your device with another application in your platform but you still to access it with imagescanner, please, fill a bug report.
