WIA_IPS_THRESHOLD

The WIA_IPS_THRESHOLD property contains the current hardware threshold setting for a device. The WIA minidriver creates and maintains this property.

Property Type: VT_I4

Valid Values: WIA_PROP_RANGE

Access Rights: Read/write

Remarks

You should map values for the WIA_IPS_THRESHOLD property in a range from 0 through 255. The default value is 128.

An application sets WIA_IPS_THRESHOLD to change the hardware threshold value. This value is valid only if the WIA_IPA_DATATYPE property is equal to WIA_DATA_THRESHOLD. If a device does not allow WIA_DATA_THRESHOLD to be changed, it should report the default value of 128.
