The WIA_IPS_PATCH_CODE_SEARCH_TIMEOUT property describes the maximum time to search for patch codes on a document page.
Property Type: VT_I4
Valid Values: WIA_PROP_RANGE
Access Rights: Read/Write
The time unit is not specified (it can be milliseconds or tenths of a second for example) but the application can choose values in the minimum – maximum range reported by the WIA minidriver.
This property is required for all Patch Code Reader items. The property can be implemented to support a range containing one single value (meaning the application cannot change this timeout)
