wiamindr_lh.h header

This header is used by image. For more information, see:

• Imaging devices

wiamindr_lh.h contains the following programming interfaces:

Interfaces

IWiaDrvItem The IWiaDrvItem interface provides methods that a WIA minidriver can use to manage a tree of IWiaDrvItem items.
IWiaMiniDrv The IWiaMiniDrv interface provides the methods that are the entry points for all communication between the minidriver and the WIA service. These methods allow the WIA service to control the device.
IWiaMiniDrvCallBack The IWiaMiniDrvCallBack interface provides the MiniDrvCallback method, which enables minidrivers to transfer image header data and image data from the imaging device to the WIA service.
IWiaMiniDrvTransferCallback This is a Callback interface that is called by the WIA mini-driver for stream-based transfers.

Structures

MINIDRV_TRANSFER_CONTEXT The MINIDRV_TRANSFER_CONTEXT structure is used to store image and other information needed for a memory-callback data transfer or a file data transfer.
WIA_DEV_CAP_DRV The WIA_DEV_CAP_DRV structure is used to enumerate device capabilities. A device capability is defined by an event or command that the device supports.
WIA_PROPERTY_CONTEXT The WIA_PROPERTY_CONTEXT structure stores property identifiers and their context.
WIA_PROPERTY_INFO The WIA_PROPERTY_INFO structure is used to store default access and valid value information for an item property of arbitrary type.
WIAS_CHANGED_VALUE_INFO The WIAS_CHANGED_VALUE_INFO structure is used to store the current and previous values of a property.
WIAS_DOWN_SAMPLE_INFO The WIAS_DOWN_SAMPLE_INFO structure stores information used by the downsampling helper function, wiasDownSampleBuffer.
WIAS_ENDORSER_INFO The WIAS_ENDORSER_INFO structure holds custom endorser token/value pairs.
WIAS_ENDORSER_VALUE The WIAS_ENDORSER_VALUE structure stores token/value pairs for endorser strings.
