System_CAPS_pubpropertyValue

Gets the Matrix that represents this MatrixTransform.(Overrides Transform.Value.)

NameDescription
System_CAPS_pubmethodApplyAnimationClock(DependencyProperty, AnimationClock)

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.)

System_CAPS_pubmethodApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.(Inherited from Animatable.)

System_CAPS_pubmethodBeginAnimation(DependencyProperty, AnimationTimeline)

Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.)

System_CAPS_pubmethodBeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior)

Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable.)

System_CAPS_pubmethodCheckAccess()

Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

System_CAPS_pubmethodClearValue(DependencyProperty)

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethodClearValue(DependencyPropertyKey)

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)

System_CAPS_pubmethodClone()

Creates a modifiable copy of this MatrixTransform by making deep copies of its values.

System_CAPS_pubmethodCloneCurrentValue()

Creates a modifiable copy of this MatrixTransform object by making deep copies of its values. This method does not copy resource references, data bindings, or animations, although it does copy their current values.

System_CAPS_pubmethodCoerceValue(DependencyProperty)

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethodEquals(Object)

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethodFreeze()

Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)

System_CAPS_pubmethodGetAnimationBaseValue(DependencyProperty)

Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.)

System_CAPS_pubmethodGetAsFrozen()

Creates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)

System_CAPS_pubmethodGetCurrentValueAsFrozen()

Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference.(Inherited from Freezable.)

System_CAPS_pubmethodGetHashCode()

Gets a hash code for this DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethodGetLocalValueEnumerator()

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodGetValue(DependencyProperty)

Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethodInvalidateProperty(DependencyProperty)

Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.)

System_CAPS_pubmethodReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)

System_CAPS_pubmethodSetCurrentValue(DependencyProperty, Object)

Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)

System_CAPS_pubmethodSetValue(DependencyProperty, Object)

Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethodSetValue(DependencyPropertyKey, Object)

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)

Creates a string representation of this instance, based on the passed IFormatProvider parameter.(Inherited from GeneralTransform.)

System_CAPS_pubmethodTransform(Point)

Transforms the specified point and returns the result.(Inherited from GeneralTransform.)

System_CAPS_pubmethodTransformBounds(Rect)

Transforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it.(Inherited from Transform.)

System_CAPS_pubmethodTryTransform(Point, Point)

Attempts to transform the specified point and returns a value that indicates whether the transformation was successful. (Inherited from Transform.)

System_CAPS_pubmethodVerifyAccess()

Enforces that the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

NameDescription
System_CAPS_pubfieldSystem_CAPS_staticMatrixProperty

Identifies the Matrix dependency property.

NameDescription
System_CAPS_pubeventChanged

Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodIFormattable.ToString(String, IFormatProvider)

Formats the value of the current instance using the specified format.(Inherited from GeneralTransform.)

Use the MatrixTransform class to create custom transformations that are not provided by the RotateTransform, SkewTransform, ScaleTransform, or TranslateTransform classes.

A 3x3 matrix is used for transformations in a 2-D x-y plane. You can multiply affine matrix transformations to form linear transformations, such as rotation and skew (shear) that are followed by translation.

An affine matrix transformation has its final column equal to (0, 0, 1); therefore, you only have to specify the members in the first two columns.

A Windows Presentation Foundation (WPF) Matrix has the following structure:

M11

M12

0

M21

M22

0

OffsetX

OffsetY

1

The members in the last row, OffsetX and OffsetY, represent translation values.

Methods and properties usually specify the transformation matrix as a vector that has only six members; the members are as follows:

    (M11, M12, M21, M22, OffsetX, OffsetY)

<object property="m11, m12, m21, m22, offsetX, offsetY"/>
- or -
<object property="Identity"/>

m11

System.Double

The value at position (1, 1) of the transformation Matrix.

m12

System.Double

The value at position (1, 2) of the transformation Matrix.

m21

System.Double

The value at position (2, 1) of the transformation Matrix.

m22

System.Double

The value at position (2, 2) of the transformation Matrix.

offsetX

System.Double

The value at position (3, 1) of the transformation Matrix.

offsetY

System.Double

The value at position (3, 2) of the transformation Matrix.
