Scanner access with WIA via WPF
Pete Brown has created an example of accessing a scanner with WIA via WPF. In the past we've chatted about going paperless with WIA and accessing a camera with it too, but Pete talks about how WIA the guts of it works and how to get an application to leverage it.
To find out more about WIA on top of Pete's example, head over to MSDN's section on it. https://msdn.microsoft.com/en-us/library/ms630368(VS.85).aspx
