WIA_IPA_FORMAT
The WIA_IPA_FORMAT property contains the current format of the image that is about to be transferred. The WIA minidriver creates and maintains this property.
Property Type: VT_CLSID
Valid Values: WIA_PROP_LIST
Access Rights: Read/write
Remarks
If you can set the device to only a single value, create a WIA_PROP_LIST type, and place the valid value in it.
For Windows 8 and later versions of Windows, the following values have been added for the WIA_IPA_FORMAT property:
WiaImgFmt_CSV
WiaImgFmt_JBIG2
WiaImgFmt_RawBar
WiaImgFmt_RawMic
WiaImgFmt_RawPat
WiaImgFmt_XmlBar
WiaImgFmt_XmlMic
WiaImgFmt_XmlPat
For both the WiaImgFmt_PDFA and WiaImgFmt_XPS formats, the drivers should support any WIA_IPA_COMPRESSION value. For these two formats, the default WIA_IPA_COMPRESSION value, WIA_COMPRESSION_NONE, means "not defined." The scanner (or the driver, where the PDF/A or XPS file is generated) must choose the internal compression mode that is used for image data.
