This method retrieves information about the transformation that affects where this UI element is displayed.

Syntax

virtual HRESULT STDMETHODCALLTYPE GetRenderTransform(
    IXRTransform** ppRenderTransform
) = 0;

Parameters

ppRenderTransform
[out] Pointer the address of a IXRTransform derived object which defines functionality that enables transformations in a two-dimensional plane on the graphical window.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

The following table shows different kinds of single-element transformations.

Transformation type	Number of affected elements	Class
Rotation	Applies to one element	IXRRotateTransform
Scale	Applies to one element	IXRScaleTransform
Skew	Applies to one element	IXRSkewTransform
Translation	Applies to one element	IXRTranslateTransform
Group	Applies to a group of elements	IXRTransformGroup

The IXRTransformGroup object is not actually a transformation, but is instead a container that enables you to specify more than one transformation to apply to this UI element.

To use a specific interface pointer type, you can use the helper template version of this method that XAML for Windows Embedded provides. When you supply a derived type, this version automatically supplies a type-safe method that implicitly converts the returned type from a generic interface so you do not have to explicitly call QueryInterface to convert the generic interface into the required object type.
