IPointerPointTransform IPointerPointTransform IPointerPointTransform IPointerPointTransform Interface

Definition

Namespace:: Windows.UI.Input Windows.UI.Input Windows.UI.Input Windows.UI.Input

Edit

Provides generalized transformation functions.

public : interface IPointerPointTransformpublic interface IPointerPointTransformPublic Interface IPointerPointTransform// You can use this interface in JavaScript.

Attributes: ContractVersionAttribute GuidAttribute

Windows 10 requirements

Device family	Windows 10 (introduced v10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced v1)

Remarks

Do not call this interface directly. IPointerPointTransform is used by a GestureRecognizer to get transformation information for an input pointer.

Properties

Inverse Inverse Inverse Inverse

Edit

Gets the inverse of the specified transformation.

public : IPointerPointTransform Inverse { get; }public IPointerPointTransform Inverse { get; }Public ReadOnly Property Inverse As IPointerPointTransform// You can use this property in JavaScript.

Value: IPointerPointTransform IPointerPointTransform IPointerPointTransform IPointerPointTransform

The inverse of the pointer transformation.

Methods

TransformBounds(Rect) TransformBounds(Rect) TransformBounds(Rect) TransformBounds(Rect)

Edit

Transforms the specified bounding rectangle.

public : Rect TransformBounds(Rect rect)public Rect TransformBounds(Rect rect)Public Function TransformBounds(rect As Rect) As Rect// You can use this method in JavaScript.

Parameters

rect: Rect Rect Rect Rect

The bounding rectangle to transform.

Returns

Rect Rect Rect Rect

The smallest, axis-aligned bounding box that encloses rect after the transformation. (An axis-aligned bounding box is one which has all sides parallel to the coordinate axes.)

Remarks

rect is typically the ContactRect associated with the input point that is transformed through the TryTransform method. rect must be recalculated as it does not change with the transformation of the input point.

This method should return an HResult that identifies whether the transformation was successful.

TryTransform(Point, Point) TryTransform(Point, Point) TryTransform(Point, Point) TryTransform(Point, Point)

Edit

Attempts to perform the transformation on the specified input point.

public : PlatForm::Boolean TryTransform(Point inPoint, Point outPoint)public bool TryTransform(Point inPoint, Point outPoint)Public Function TryTransform(inPoint As Point, outPoint As Point) As bool// You can use this method in JavaScript.

Parameters

inPoint: Point Point Point Point

The original input point.

outPoint: Point Point Point Point

The transformed input point.

Returns

PlatForm::Boolean bool bool bool

True if inPoint was transformed successfully; otherwise, false.
