Standard for image acquisition devices (TWAIN).Image and Scanner Interface Specification (ISIS).However, video content support is removed from WIA for Windows Vista. Multi-image scanning allows one to scan several images at once and save them directly as separate files. Push scanning allows initiating scans and adjusting scanning parameters directly from the scanner control panel. WIA2 supports push scanning and multi-image scanning. Windows Vista also has the WIA Automation library built-in. Windows Vista introduced Windows Image Acquisition 2.0.

For WIA video, a snapshot filter driver is introduced that allows still frames to be captured from the video stream. In Windows XP, support was added for automatic document feeder scanners, scroll-feed scanners without preview capabilities and multi-page TIFF generation.
This can result in compatibility issues when using a driver designed for Windows XP. Because of the security ramifications of running a service as LocalSystem whereby a buggy driver or malicious person would have unrestricted access to the system, the WIA service in Windows Server 2003 and Windows Vista operates in the LocalService context.
In Windows XP, WIA runs in the LocalSystem context. In 2002, Microsoft released the Windows Image Acquisition Automation Library Tool, which provides access to WIA functionality through programming languages and scripting environments that support OLE Automation.
#260CI WIA USB DRIVER DRIVERS#
Whereas STI only provided a low-level interface for doing basic transfers of data to and from the device (as well as the invocation of an image scan process on the Windows machine through the external device), WIA provides a framework through which a device can present its unique capabilities to the operating system, and applications can invoke those features.Īccording to Microsoft, WIA drivers are made up of a user interface (UI) component and a driver core component, loaded into two different process spaces: UI in the application space and the driver core in the WIA service space.Ĭertain scanners support WIA. WIA is a very significant superset of the support for digital still imaging drivers that was provided by the Still Image Architecture (STI) in Windows 98.
