wia_scan 0.4.1

wia_scan

A simple utility for using document scanners that support Windows Image Acquisition (WIA) and is easy to install. If your scanner works using Windows Fax and Scan, there is a good chance it will work with this python script.

Use cases:

• You have a flatbed scanner and you need to scan a lot of documents, thus you don't want to use Windows Fax and Scan tool as it can introduce quite some overhead.
• Support scanners on Windows using a simple python dependency

Alternatives: Existing WIA libraries, but to my surprise the ones I found required quite old versions of python, which I didn't want since I wanted to combine the scanning process with some modern python packages.

Installation

pip install wia_scan

Alternative: From Source

Download this source and install flit uisng pip install flit and run the following command from the source folder

flit install

Example: Scan 10 single sided documents from the same scanner:

from wia_scan import *

print_function = print
device_manager = get_device_manager()
device_identifier = prompt_choose_device(device_manager=device_manager, print_function=print_function)
device = connect_device(device_manager=device_manager,
                        device_identifier=device_identifier, print_function=print_function)
for i in range(10):
    os.system("pause")
    wia_image = scan_side(device=device, settings=DEFAULT_SCAN_SETTINGS,
                        print_function=print_function)
    wia_image.SaveFile(f'{i}.jpeg')
