Welcome to pytwain’s documentation!¶
Overview¶
The Python TWAIN module provides an interface to scanners, digital cameras and other devices which implement TWAIN, for Windows and Mac platforms.
It provides the functionality to allow a Python application to connect to the scanner/camera and to retrieve images from that device.
If you use 64-bit Python on Windows you need to install 64 bit TWAIN DSM: http://sourceforge.net/projects/twain-dsm/. Although there is a good chance that your scanner’s driver is not compatible with 64-bit TWAIN DSM, in this case you will get an empty list when you enumerate scanners. If you have this issue try using 32-bit Python with TWAIN DSM supplied with Windows.
