Projects

WiaSane

WiaSane

The WiaSane project provides a Windows Image Acquisition (WIA) Driver which enables image acquisition from scanner devices through the Scanner Access Now Easy (SANE) network protocol. This WIA driver implements a SANE frontend on top of the SANE network protocol. It is referred to as Scanner Access Now Easy - WIA Driver.

In order to access those scanner devices either the scanner itself or a SANE daemon needs to provide a SANE network frontend to be used. Downloads can either be found on the corresponding wiki page or on the release overview.
