The IEnumWIA_DEV_CAPS interface enumerates the currently available Windows Image Acquisition (WIA) hardware device capabilities. Device capabilities include commands and events that the device supports.
The IEnumWIA_DEV_INFO interface enumerates the currently available Windows Image Acquisition (WIA) hardware devices and their properties. Device information properties describe the installation and configuration of WIA hardware devices.
Provides an application callback mechanism during data transfers from Windows Image Acquisition (WIA) hardware devices to applications.Note For Windows Vista applications, use IWiaTransferCallback instead of IWiaDataCallback.
The IWiaPropertyStorage interface is used to access information about the IWiaItem object's properties. Applications must query an item to obtain its IWiaPropertyStorage interface.
The WIA_DATA_CALLBACK_HEADER is transmitted to an application during a series of calls by the Windows Image Acquisition (WIA) run-time system to the IWiaDataCallback::BandedDataCallback method.
The WIA_DATA_TRANSFER_INFO structure is used by applications to describe the buffer used to retrieve bands of data from Windows Image Acquisition (WIA) devices. It is primarily used in conjunction with the methods of the IWiaDataTransfer interface.
Applications use the WIA_DEV_CAP structure to enumerate device capabilities. A device capability is defined by an event or command that the device supports. For more information, see IEnumWIA_DEV_CAPS.
The WIA_DITHER_PATTERN_DATA structure specifies a dither pattern for scanners. It is used in conjunction with the scanner device property constant WIA_DPS_DITHER_PATTERN_DATA.
Provides a quick means by which applications can look up the standard Windows Image Acquisition (WIA) property name from the WIA property ID (or vice versa).
This learning path covers Windows Management Instrumentation (WMI) and Common Information Model (CIM). These technologies help to access information about a computer. Additionally, both technologies provide local and remote access to management information from the operating system, computer hardware, and installed software.
