Remarks

ITransformProvider2 extends the ITransformProvider interface to enable Microsoft UI Automation providers to expose properties to support the viewport zooming functionality of a control.

Classes such as TransformPattern2Identifiers are the identifiers for the Windows Runtime implementation of a common provider pattern for Microsoft UI Automation. You might use these identifiers if you are implementing a Windows Runtime custom automation peer that reports support for ITransformProvider2 in its GetPattern(Windows.UI.Xaml.Automation.Peers.PatternInterface) implementation. These identifiers are needed for the RaisePropertyChangedEvent(Windows.UI.Xaml.Automation.AutomationProperty,System.Object,System.Object) calls that you make from control code that references your own peer, or for FindItemByProperty(Windows.UI.Xaml.Automation.Provider.IRawElementProviderSimple,Windows.UI.Xaml.Automation.AutomationProperty,System.Object) in an items container peer. This same pattern is usually exposed to clients in a different way, depending on which technology they use to implement the client and examine the Microsoft UI Automation tree. ITransformProvider2 is also presented as a Component Object Model (COM) interface.
