This section contains reference information for the following technologies:

WIA and STI Driver Reference Table

The following table contains reference information for Windows Image Acquisition (WIA) drivers and for Still Imaging (STI) drivers. These drivers control devices, including scanners and cameras, that capture still images. For more information about these drivers, see Windows Image Acquisition Drivers and Still Image Drivers.

The following sections describe the interfaces, functions, structures, and properties used by WIA and STI drivers.

Section	Description
Device Interface Classes for Imaging Devices	Device class GUID for imaging devices.
IWiaMiniDrv Interface	Interface for managing all communications between a WIA minidriver and the WIA service.
WIA Driver Services Library Functions	Helper functions used by a WIA minidriver to manage device items and data transfers.
WIA Properties	Properties of WIA devices, including status, capabilities, and device identification information.
WIA Utility Library Functions and Classes	Utility functions and classes used by a WIA minidriver to support debugging and to perform common tasks.
IWiaMiniDrvCallBack Interface	Callback interface for transferring status and image data between the WIA service and a WIA minidriver.
IWiaDrvItem Interface	Interface used by a WIA minidriver to manage a tree of WIA driver items.
IWiaErrorHandler Interface	Interface used by a WIA minidriver to provide error status and to support error recovery.
IWiaImageFilter Interface	Interface implemented by an image processing filter and called by the WIA service to communicate with the filter.
IWiaLog Interface and Diagnostic Log Macros	Interface and macros used by a WIA minidriver to record trace, error, and warning messages to a diagnostic log file.
IWiaSegmentationFilter Interface	Interface used by a WIA minidriver to detect regions in a segmented image.
IWiaTransferCallback Interface	Interface implemented by an image processing filter and called by the WIA service to initiate the processing of image streams.
