A TransformGesture interprets pointer gestures and modifies an InteractiveTransform in response.

Note that the TransformGesture on its own has no visual impact, it only modifies the InteractiveTransform, which provides the actual visual transformation. For example here is a simple image viewing setup:

<Panel HitTestMode="LocalBounds">
    <Image File="my_image.jpg">
        <InteractiveTransform ux:Name="ImageTrans"/>
    <ZoomGesture Target="ImageTrans"/>
    <PanGesture Target="ImageTrans"/>
    <RotateGesture Target="ImageTrans"/>

One InteractiveTransform can be the target of multiple gestures. They will coorindate correctly with each other to provide a unified experience. The InteractiveTransform will contain values that represent the total transformation.

For a complete list of single-finger gestures such as Tapped, LongPress etc., see Triggers.

Interface of TransformGesture

Inherited from Node

ContextParent : Node uno

The context parent is the semantic parent of this node. It is where non-UI structure should be resolved, like looking for the DataContext, a Navigation, or other semantic item.

FindNodeByName(Selector, Predicate<Node> (Node)) : Node uno

Finds the first node with a given name that satisfies the given acceptor. The serach algorithm works as follows: Nodes in the subtree are matched first, then it matches the nodes in the subtrees ofthe ancestor nodes by turn all the way to the root. If no matching node is found, the function returns null.

IsRootingStarted : bool uno

Whether rooting of this node has started. Note that even if this property returns true, rooting may not yet be completed for the node. See also IsRootingCompleted.

Name : Selector ux

Run-time name of the node. This property is automatically set using the ux:Name attribute.

OnRooted uno

If you override OnRooted you must call base.OnRooted() first in your derived class. No other processing should happen first, otherwise you might end up in an undefined state.
