Each Windows Image Acquisition (WIA) hardware device is represented to an application as a hierarchical tree of WiaItem objects. The WiaItem interface provides applications with the ability to query devices to discover their capabilities. It also provides access to data transfer interfaces and item properties. In addition, the WiaItem interface provides methods to enable applications to control the device.
This class encapsulates transparently the system classes for WIA 1.x and 2.x.
