WiaItemPropertyId

Most of the Windows Image Acquisition (WIA) property constants are grouped in one enumerated data type, WiaItemPropertyId for scripting authors.

The following table presents the mapping between the naming conventions used in scripting and C++. For example, in script the "CameraDevice" prefix maps to the "WIA_DPC" prefix for the corresponding C++ constant. In a more specific example, the "CameraDeviceFlashMode" property is equivalent to the C++ "WIA_DPC_FLASH_MODE" constant. See the corresponding property constant topics for descriptions of each property.

Script Prefix	C++ Topic (prefix)
Device	Common Device Property Constants (WIA_DPA)
CameraDevice	Camera Device Property Constants (WIA_DPC)
ScannerDevice	Scanner Device Property Constants (WIA_DPS)
VideoDevice	Video WIA Device Property Constants (WIA_DPV)
Picture	Common WIA Item Property Constants (WIA_IPA)
CameraPicture	Camera WIA Item Property Constants (WIA_IPC)
ScannerPicture	Scanner WIA Item Property Constants (WIA_IPS)
