#Remarks
This function returns 0 if the Smart Image container supports the interface whose global unique 128-bit identifier is passed as the IID parameter; otherwise, E_NOINTERFACE. If a TdxCustomSmartImage class descendant supports the specified interface, the QueryInterface function returns a reference to the interfaced object as the Obj out parameter and increments the reference counter.
