SkewTransform Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents a two-dimensional skew.


Namespace:  System.Windows.Media
Assembly:  System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.

public sealed class SkewTransform : Transform
<SkewTransform .../>

The SkewTransform type exposes the following members.

Public methodSkewTransformInitializes a new instance of the SkewTransform class.

Public propertyAngleXGets or sets the x-axis skew angle, which is measured in degrees counterclockwise from the y-axis.
Public propertyAngleYGets or sets the y-axis skew angle, which is measured in degrees counterclockwise from the x-axis.
Public propertyCenterXGets or sets the x-coordinate of the transform center.
Public propertyCenterYGets or sets the y-coordinate of the transform center.
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyInverseGets the inverse of this transform, if it exists. (Inherited from Transform.)

Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodTransformTransforms the specified point and returns the result. (Inherited from GeneralTransform.)
Public methodTransformBoundsTransforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it. (Inherited from Transform.)
Public methodTryTransformAttempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Inherited from Transform.)

Public fieldStatic memberAngleXPropertyIdentifies the AngleX dependency property.
Public fieldStatic memberAngleYPropertyIdentifies the AngleY dependency property.
Public fieldStatic memberCenterXPropertyIdentifies the CenterX dependency property.
Public fieldStatic memberCenterYPropertyIdentifies the CenterY dependency property.

A SkewTransform is useful for creating the illusion of three-dimensional depth in a two-dimensional object.

The local origin 0,0 for an object can be offset on a Canvas using Canvas.Left and Canvas.Top, but this does not count as a transform; the object retains its own local 0,0 in this case for transformation purposes.

Multiple transforms can be applied with a TransformGroup. Custom transforms can be created with a MatrixTransform.

The following illustration shows three examples of a SkewTransform applied to a Rectangle.

Different AngleX, AngleY, and Center values.

Transforms can alter the display of text in your application to create a decorative effect. The following illustration shows text skewed along the x-axis.

A typeface can simulate an italic style by shearing, or skewing, a glyph. However, a non-simulated italic typeface is typically designed to have a better visual appearance than a simulated italic typeface.

The example below shows how to increase the AngleX property value of a SkewTransform applied to a Rectangle every time the Rectangle is clicked.

    <Rectangle MouseLeftButtonDown="IncreaseSkew"
Width="50" Height="50" Fill="RoyalBlue">

            <!-- If you give the transform a name you can access 
    it easily from code. -->
            <SkewTransform x:Name="mySkewTransform" />

public void IncreaseSkew(object sender, EventArgs e)
    mySkewTransform.AngleX = mySkewTransform.AngleX + 5;

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
