Remarks

Transformation types include rotation (RotateTransform), scale (ScaleTransform), skew/shear (SkewTransform), and translation (TranslateTransform).

MatrixTransform is for transforms that don't use these conventions and instead use Matrix values for transform definition.

CompositeTransform and TransformGroup both support specifying multiple transforms for a combined transformation logic.

You can animate properties of a transform. For XAML syntaxes that take a Transform, you need to specify a nonabstract derived type of Transform as an object element. Typically, this is one of: MatrixTransform, RotateTransform, ScaleTransform, SkewTransform, or TranslateTransform. See the syntax sections on the appropriate class.

Use the MatrixTransform class to create custom transformations that are not provided by the other Transform derived classes. A two-dimensional x-y plane uses a 3x3 matrix for transformations.

Transform is the property type for UIElement.RenderTransform. With this property, you can apply any of the practical transforms to a UIElement when it renders. Other less commonly used properties that take a Transform are: Brush.RelativeTransform, Brush.Transform, Geometry.Transform.

Transform derived classes

Transform is the parent class for several derived classes that define different categories of transformations:

Properties

Dispatcher	Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
Inverse	Gets the inverse transformation of this GeneralTransform, if possible. (Inherited from GeneralTransform)
InverseCore	Implements the behavior for return value of Inverse in a derived or custom GeneralTransform. (Inherited from GeneralTransform)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
TransformBounds(Rect)	Transforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it. (Inherited from GeneralTransform)
TransformBoundsCore(Rect)	Provides the means to override the TransformBounds behavior in a derived transform class. (Inherited from GeneralTransform)
TransformPoint(Point)	Uses this transformation object's logic to transform the specified point, and returns the result. (Inherited from GeneralTransform)
TryTransform(Point, Point)	Attempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Inherited from GeneralTransform)
TryTransformCore(Point, Point)	Provides the means to override the TryTransform behavior in a derived transform class. (Inherited from GeneralTransform)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
