What is WIA, and can TwainControlX be used with WIA?

WIA stands for Windows Image Acquisition and is an alternative standard for acquiring images from scanners and cameras. It has been introduced by Microsoft and is available in Windows XP. WIA device drivers are able to communicate with applications that are TWAIN-complaint, such as TwainControlX, however these drivers usually exhibit limitations in their functionality. In particular, hiding the user interface of a scanner may appear to work, but often gives unreliable results.

We do not recommend the use of WIA drivers with TwainControlX. The standard, TWAIN-compliant drivers which are readily available for the vast majority of scanners should be used instead.
