Remarks

Specifies which Twain capability to negotiate. It is also used to set which extended image information is to be requested. This is a runtime-only property.

This property should be used only when a capability that is not directly supported by the Capability property is needed. This property is ignored unless the Capability property has been set to either TWCAP_USECAPADVANCED or TW_CAPUSECAPADVANCEDFOREXTINFO. All capability functions are available except the CapDesc property when the Capability property is set to TWCAP_USECAPADVANCED. When the Capability is set to TWCAP_USECAPADVANCEDFOREXTINFO then neither CapDesc or any of the capability out properties such as CapValueOut are available.

See the section for accessing Extended Image Information when the Capability property is set to TW_CAPUSECAPADVANCEDFOREXTINFO.
