Methods
  NameDescription
Public methodApplyAnimationClock(DependencyProperty, AnimationClock)
Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.
(Inherited from Animatable.)
Public methodApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)
Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.
(Inherited from Animatable.)
Public methodBeginAnimation(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.)
Public methodBeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior)

(Inherited from Animatable.)
Public methodCheckAccess
Determines whether the calling thread has access to this DispatcherObject.
(Inherited from DispatcherObject.)
Public methodClearValue(DependencyProperty)
Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.
(Inherited from DependencyObject.)
Public methodClearValue(DependencyPropertyKey)
Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey.
(Inherited from DependencyObject.)
Public methodClone
Creates a modifiable clone of this Animatable, making deep copies of this object's values. When copying this object's dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values.
(Inherited from Animatable.)
Protected methodCloneCore
Makes the instance a clone (deep copy) of the specified Freezable using base (non-animated) property values.
(Inherited from Freezable.)
Public methodCloneCurrentValue
Creates a modifiable clone (deep copy) of the Freezable using its current values.
(Inherited from Freezable.)
Protected methodCloneCurrentValueCore
Makes the instance a modifiable clone (deep copy) of the specified Freezable using current property values.
(Inherited from Freezable.)
Public methodCoerceValue
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.)
Protected methodConfineToImage(Point)
Returns a modified Point that is confined to the image area.
(Inherited from MouseTool.)
Protected methodConfineToImage(Rect)
Returns a Rect that is confined to the image.
(Inherited from MouseTool.)
Protected methodConfineToRenderedImage
Returns a rectangle confined to the rendered size of the image.
(Inherited from MouseTool.)
Protected methodCreateInstance
Initializes a new instance of the Freezable class.
(Inherited from Freezable.)
Protected methodCreateInstanceCore
Returns a new instance of PanningMouseTool.
(Overrides FreezableCreateInstanceCore.)
Public methodEquals
Determines whether a provided DependencyObject is equivalent to the current DependencyObject.
(Inherited from DependencyObject.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodFreeze
Makes the current object unmodifiable and sets its IsFrozen property to true.
(Inherited from Freezable.)
Protected methodFreezeCore
Makes this Animatable object unmodifiable or determines whether it can be made unmodifiable.
(Inherited from Animatable.)
Public methodGetAnimationBaseValue
Returns the non-animated value of the specified DependencyProperty.
(Inherited from Animatable.)
Public methodGetAsFrozen
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.)
Protected methodGetAsFrozenCore
Makes the instance a frozen clone of the specified Freezable using base (non-animated) property values.
(Inherited from Freezable.)
Public methodGetCurrentValueAsFrozen
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.)
Protected methodGetCurrentValueAsFrozenCore
Makes the current instance a frozen clone of the specified Freezable. If the object has animated dependency properties, their current animated values are copied.
(Inherited from Freezable.)
Public methodGetHashCode
Gets a hash code for this DependencyObject.
(Inherited from DependencyObject.)
Protected methodGetImagePosition(MouseButtonEventArgs, Boolean)
Returns the image position from a MouseButtonEventArgs.
(Inherited from MouseTool.)
Protected methodGetImagePosition(MouseEventArgs, Boolean)
Returns the image position from a MouseEventArgs.
(Inherited from MouseTool.)
Protected methodGetImagePosition(Point, Boolean)
Returns the image position from a point in viewer coordinates.
(Inherited from MouseTool.)

Returns the local value of a dependency property, if it exists.
(Inherited from DependencyObject.)
Protected methodReadPreamble
Ensures that the Freezable is being accessed from a valid thread. Inheritors of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties.
(Inherited from Freezable.)
