Mapping WIA properties with the same IDs and names
Important
This article contains information that applies to obsolete Windows operating systems.
There are Windows XP properties that have the same property IDs and property names as their Windows Vista counterparts. The following is a table of these Windows XP root properties and the FLATBED and FEEDER (ADF) properties that they are translated to in Windows Vista.

Note a: FEEDER item (ADF) or FEEDER context on the Windows XP root or child item (WIA_DPS_DOCUMENT_HANDLING_SELECT is set to FEEDER).
Note b: FLATBED item or FLATBED context on the Windows XP root or child item (WIA_DPS_DOCUMENT_HANDLING_SELECT is set to FLATBED).
Note c: Root item, no context specified for Windows XP.
Note d: Managed by the WIA service.
Note e: Customized for application's application item tree (A-AIT).
Note f: Add to A-AIT even when not supported on driver's application item tree (D-AIT). Set to WiaImgFmt_BMP.
Note g: For Windows Vista to Windows XP translation, add WiaImgFmt_MEMORYBMP to be used with TYMED_CALLBACK.
Note h: For Windows Vista to Windows XP translation, add TYMED_CALLBACK and WiaImgFmt_MEMORYBMP. For Windows XP to Windows Vista translation, only TYMED_FILE and TYMED_MULTIPAGE_FILE are translated.
Note i: For Windows XP to Windows Vista translation, translate only:
TYMED_FILE
TYMED_MULTIPAGE_FILE
Note j: For Windows XP to Windows Vista translation, translate only:
DUP
FEED
FLAT
DETECT_FEED
DETECT_FLAT
DETECT_SCAN
Note k: Add to A-AIT even when not supported on D-AIT. Set to TYMED_FILE.
Note l: Add to A-AIT even when not supported on D-AIT.
Note m: Optional for Windows Vista for all transfer-enabled devices. If these properties are implemented, the legacy applications can get estimate on the number of pixels per line, number of bytes required for each scan line, and total number of scan lines in the image. These values are not accurate because the image processing filter might modify the actual values that these properties represent.
If these properties are not supplied by the Windows Vista driver, the compatibility layer in WIA service will add these properties. When these properties are added by WIA service, they will be updated using properties: WIA_IPA_DEPTH, WIA_IPS_XEXTENT, and WIA_IPS_YEXTENT.
When possible, applications should always parse the image header data to get accurate information on the image. They should not rely on this property since it is not accurate.
