DirectionalBlurEffect Class
namespace NoesisApp
Blurs an object along a specific angle, to create a blurred streaking effect.
The directional blur effect is similar to BlurEffect, except you can skew the blur in a particular direction. You can use this effect to make an image look as if it is in motion or to emphasize an animated image.

Properties
| Name | Description |
|---|---|
| Angle | Gets or sets the angle of the blur relative to the x-axis, in the counterclockwise direction. The units are specified in degrees |
| Radius | Gets or sets the amount of blur to be applied to the image |
Dependency Property Reflection Property

|---|---|
| CanFreeze | Gets a value that indicates whether the object can be made unmodifiable. |
| IsFrozen | Gets a value that indicates whether the object is currently modifiable. |

Methods
From Freezable
| Name | Description |
|---|---|
| Clone() | Creates a modifiable clone of the Freezable, making deep copies of the object's values. When copying the object's dependency properties, this method copies expressions (which might no longer resolve) but not animations or their current values. The cloned Freezable::IsFrozen property is false even if the source's IsFrozen property is true. |
| CloneCurrentValue() | Creates a modifiable clone (deep copy) of the Freezable using its current values. The cloned object's IsFrozen property is false even if the source's IsFrozen property is true. |
| Freeze() | Makes the current object unmodifiable and sets its IsFrozen property to true. |
| 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. The copy's IsFrozen property is set to true. Throws if the Freezable cannot be frozen because it contains expressions or animated properties. |
| 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. The copy's IsFrozen property is set to true. |
From DependencyObject
| Name | Description |
|---|---|
| ClearAnimation(dp) | Clears the animation value of a property |
| ClearLocalValue(dp) | Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier |
| CoerceValue(dp) | Coerces and validates the effective property value |
| DependencyPropertyChanged() | Returns the PropertyChanged event |
| Destroyed() | Destroyed delegate is raised when object is going to be destroyed |
| GetBaseValue(dp) | Returns the base value without animation nor coerce (this never returns Expression like GetLocalValue) |
| GetExpression(dp) | Gets the expression, if any, used to evaluate the specified property value |
| GetLocalValue(dp) | Returns the local value of a dependency property, if it exists |
| GetValue(dp) | Returns the current effective value of a dependency property on this instance of a DependencyObject |
| GetValueObject(dp) | Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value |
| GetValueProvider(dp) | Gets the provider that returns the effective value for the specified dependency property |
| HasAnimatedProperties() | Returns true if there is any animated property |
| InvalidateProperty(dp, priority) | Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed |
| IsCached(dp, provider) | Returns if the value is stored in the cache. If true, the priority is returned in the provider field |
| IsSealed() | Gets a value that indicates whether this instance is currently sealed (read-only) |
| SetAnimation(dp, value) | Sets the animated value of a property |
| SetCurrentValue(dp, value) | Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value |
| SetCurrentValueObject(dp, value) | Sets the current value of a dependency property using a boxed value |
| SetExpression(dp, expression) | Sets the expression to be evaluated dynamically to obtain the value of the property |
| SetValue(dp, value) | Sets the local value of a dependency property |
| SetValueObject(dp, value) | Sets the local value (boxed) of a dependency property |
From DispatcherObject
| Name | Description |
|---|---|
| CheckAccess() | Determines whether the calling thread has access to this DispatcherObject |
| VerifyAccess() | Enforces that the calling thread has access to this DispatcherObject |
