Remarks
Classes that derive from PathSegment, such as ArcSegment, BezierSegment, and LineSegment, represent specific types of geometric segments.
Freezable Features: Because PathSegment objects inherit from the Freezable class, they provide several special features: they can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features that are provided by Freezable objects, see Freezable Objects Overview.
Notes to Implementers
Although this class is abstract, it is not publicly extensible.
Fields

Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject) |
| Dispatcher |
Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject) |

| IsStroked |
Gets or sets a value that indicates whether the segment is stroked. |
Methods
| ApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior) |
Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable) |
| ApplyAnimationClock(DependencyProperty, AnimationClock) |
Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used. (Inherited from Animatable) |
| BeginAnimation(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) |
| BeginAnimation(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) |
| CheckAccess() |
Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject) |
| ClearValue(DependencyProperty) |
Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject) |
| ClearValue(DependencyPropertyKey) |
Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject) |
| Clone() |
Creates a modifiable copy of this PathSegment by making deep copies of its values. |
| CloneCore(Freezable) |
Makes the instance a clone (deep copy) of the specified Freezable using base (non-animated) property values. (Inherited from Freezable) |
| CloneCurrentValue() |
Creates a modifiable copy of this PathSegment object by making deep copies of its values. This method does not copy resource references, data bindings, and animations, although it does copy their current values. |
| CloneCurrentValueCore(Freezable) |
Makes the instance a modifiable clone (deep copy) of the specified Freezable using current property values. (Inherited from Freezable) |
| CoerceValue(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) |
| CreateInstance() |
Initializes a new instance of the Freezable class. (Inherited from Freezable) |
| CreateInstanceCore() |
When implemented in a derived class, creates a new instance of the Freezable derived class. (Inherited from Freezable) |
| Equals(Object) |
Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject) |
| Freeze() |
Makes the current object unmodifiable and sets its IsFrozen property to |
| FreezeCore(Boolean) |
Makes this Animatable object unmodifiable or determines whether it can be made unmodifiable. (Inherited from Animatable) |
| GetAnimationBaseValue(DependencyProperty) |
Returns the non-animated value of the specified DependencyProperty. (Inherited from Animatable) |
| GetAsFrozen() |
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) |
| GetAsFrozenCore(Freezable) |
Makes the instance a frozen clone of the specified Freezable using base (non-animated) property values. (Inherited from Freezable) |
| GetCurrentValueAsFrozen() |
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) |
| GetCurrentValueAsFrozenCore(Freezable) |
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) |
| GetHashCode() |
Gets a hash code for this DependencyObject. (Inherited from DependencyObject) |
| GetLocalValueEnumerator() |
Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| GetValue(DependencyProperty) |
Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject) |
| InvalidateProperty(DependencyProperty) |
Re-evaluates the effective value for the specified dependency property. (Inherited from DependencyObject) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| OnChanged() |
Called when the current Freezable object is modified. (Inherited from Freezable) |
| OnFreezablePropertyChanged(DependencyObject, DependencyObject, DependencyProperty) |
This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code. (Inherited from Freezable) |
| OnFreezablePropertyChanged(DependencyObject, DependencyObject) |
Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set. (Inherited from Freezable) |
| OnPropertyChanged(DependencyPropertyChangedEventArgs) |
Overrides the DependencyObject implementation of OnPropertyChanged(DependencyPropertyChangedEventArgs) to also invoke any Changed handlers in response to a changing dependency property of type Freezable. (Inherited from Freezable) |
| ReadLocalValue(DependencyProperty) |
Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject) |
| ReadPreamble() |
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) |
| SetCurrentValue(DependencyProperty, Object) |
Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject) |
| SetValue(DependencyProperty, Object) |
Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject) |
| SetValue(DependencyPropertyKey, Object) |
Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject) |
| ShouldSerializeProperty(DependencyProperty) |
Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject) |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
| VerifyAccess() |
Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject) |
| WritePostscript() |
Raises the Changed event for the Freezable and invokes its OnChanged() method. Classes that derive from Freezable should call this method at the end of any API that modifies class members that are not stored as dependency properties. (Inherited from Freezable) |
| WritePreamble() |
Verifies that the Freezable is not frozen and that it is being accessed from a valid threading context. Freezable inheritors should call this method at the beginning of any API that writes to data members that are not dependency properties. (Inherited from Freezable) |
Events
| Changed |
Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable) |
