This class lets you apply multiple different transforms to an object.

'Declaration Public NotInheritable Class CompositeTransform _ Inherits Transform
public sealed class CompositeTransform : Transform
The CompositeTransform type exposes the following members.
|CompositeTransform||Initializes a new instance of the CompositeTransform class.|
|CenterX||Gets or sets the x-coordinate of the center point for all transforms specified by the CompositeTransform.|
|CenterY||Gets or sets the y-coordinate of the center point for all transforms specified by the CompositeTransform.|
|Dispatcher||Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)|
|Inverse||Gets the inverse of this transform, if it exists. (Inherited from Transform.)|
|Rotation||Gets or sets the angle, in degrees, of clockwise rotation.|
|ScaleX||Gets or sets the x-axis scale factor. You can use this property to stretch or shrink an object horizontally.|
|ScaleY||Gets or sets the y-axis scale factor. You can use this property to stretch or shrink an object vertically.|
|SkewX||Gets or sets the x-axis skew angle, which is measured in degrees counterclockwise from the y-axis. A skew transform can be useful for creating the illusion of three-dimensional depth in a two-dimensional object.|
|SkewY||Gets or sets the y-axis skew angle, which is measured in degrees counterclockwise from the x-axis. A skew transform can be useful for creating the illusion of three-dimensional depth in a two-dimensional object.|
|TranslateX||Gets or sets the distance to translate along the x-axis.|
|TranslateY||Gets or sets the distance to translate (move) an object along the y-axis.|
|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 Silverlight 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. (Inherited from Transform.)|
|TryTransform||Attempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Inherited from Transform.)|
|CenterXProperty||Identifies the CenterX dependency property.|
|CenterYProperty||Identifies the CenterY dependency property.|
|RotationProperty||Identifies the Rotation dependency property.|
|ScaleXProperty||Identifies the ScaleX dependency property.|
|ScaleYProperty||Identifies the ScaleY dependency property.|
|SkewXProperty||Identifies the SkewX dependency property.|
|SkewYProperty||Identifies the SkewY dependency property.|
|TranslateXProperty||Identifies the TranslateX dependency property.|
|TranslateYProperty||Identifies the TranslateY dependency property.|
Instead of applying transforms to an object by using individual transform objects in a TransformGroup (for example, ScaleTransform or SkewTransform), you can use a single instance of the CompositeTransform object to apply all these basic transforms (see the example below). This enables you to make your XAML code more concise. In addition, CompositeTransform applies multiple transforms in the following recommended order:
If, for whatever reason, you want to apply multiple transforms to an object in a different order than is recommended here, you can use the TransformGroup to do this. The TransformGroup is also useful if you want to specify different center points for the various transforms you apply. For example, the CenterX and CenterY properties on the CompositeTransform is applied to all transforms of the CompositeTransform while you can specify different center points for ScaleTransform, SkewTransform, and RotateTransform within a TransformGroup.
The following example shows how to apply the same transforms to an object by using either a TransformGroup or a TransformGroup.
