WIA_IPS_THRESHOLD is int = 6159
Threshold is int = ScanProperty(MyScanner, WIA_IPS_THRESHOLD)
MyScanner is Scanner
let ScannerCapability = ScanProperty(MyScanner, scanPropertyCapability)
IF ScannerCapability & scanCapabilityFeeder THEN
Info("The scanner has a feeder")
END
IF ScannerCapability & scanCapabilityFlatbed THEN
Info("The scanner has a flatbed")
END
IF ScannerCapability & scanCapabilityDuplex THEN
Info("The scanner supports duplex scanning")

Syntax
Getting the properties of a scanner Hide the details
<Result> = ScanProperty(<Scanner> , <Property>)
<Result>: Type of the property Property value. If an error occurs, the ErrorOccurred variable is set to True and ErrorInfo returns the corresponding error message. <Scanner>: Scanner variable Name of the Scanner variable initialized with the information of the scanner for which we want to get a property. <Property>: Integer Property whose values are requested.
This property can correspond to: - one of the following constants from the WiaDef.h file in the Windows API: WIA_DIP_xxx, WIA_DPA_xxx, WIA_DPS_xxx, WIA_IPA_xxx, or WIA_IPS_xxx.
Caution: The properties supported vary according to the driver used. The list of properties can be found at https://github.com/tpn/winddk-8.1/blob/master/Include/um/WiaDef.h. - one of the following constants:
| | | scanPropertyCapability | Scanner capability. In this case, <Result> can be any combination of the following constants: - scanCapabilityFeeder: The scanner has a feeder.
- scanCapabilityFlatbed: The scanner has a flatbed.
- scanCapabilityDuplex: The scanner supports duplex scanning.
| | scanPropertyPaperSize | Page size currently set for scanning. In this case, <Result> can be one of the following constants: | | - scanPaperSizeA0
- scanPaperSizeA1
- scanPaperSizeA10
- scanPaperSizeA2
