Defines functionality that enables transformations in a two-dimensional plane.
Assembly: System.Windows (in System.Windows.dll)
Thetype exposes the following members.
|CheckAccess||Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)|
|ClearValue||Clears the local value of a dependency property. (Inherited from DependencyObject.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetAnimationBaseValue||Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ReadLocalValue||Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)|
|SetValue||Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Transform||Transforms the specified point and returns the result. (Inherited from GeneralTransform.)|
|TransformBounds||Transforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it. (Overrides GeneralTransform.TransformBounds(Rect).)|
|TryTransform||Attempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Overrides GeneralTransform.TryTransform(Point, Point).)|
Transformations include rotation (RotateTransform), scale (ScaleTransform), skew (SkewTransform), and translation (TranslateTransform). This class hierarchy differs from the Matrix structure because it is a class and it supports animation and enumeration semantics.
For XAML syntaxes that take a , you need to specify a nonabstract derived type of as an object element. Typically, this is one of the Windows Phone-defined classes: MatrixTransform, RotateTransform, ScaleTransform, SkewTransform, TransformGroup, and TranslateTransform. See the syntax sections on the appropriate class.
A two-dimensional x-y plane uses a 3x3 matrix for transformations. You can multiply affine transformation matrices to form linear transformations, such as rotation and skew (shear) that are followed by translation.
An affine transformation matrix has its final column equal to (0, 0, 1); therefore, you only have to specify the members in the first two columns.
You cannot extract the matrix-specific information from the nonmatrix transformations. However you can adjust the nonmatrix transformations with their specific properties, or replace a transformation with a matrix transformation at run time.
