SubType

Specifies the property subtype, one of WIA_PROP_FLAG, WIA_PROP_LIST, WIA_PROP_RANGE, or WIA_PROP_NONE. The first three constants indicate, respectively, that a property is a set of flag values, a list of values, or a range of values. The fourth constant indicates that a property is none of these.
