public sealed class BlurBitmapEffect : BitmapEffect

NameDescription
System_CAPS_pubmethodBlurBitmapEffect()

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Initializes a new instance of the BlurBitmapEffect class.

NameDescription
System_CAPS_pubpropertyCanFreeze

Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.)

System_CAPS_pubpropertyDependencyObjectType

Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.)

System_CAPS_pubpropertyDispatcher

Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)

System_CAPS_pubpropertyHasAnimatedProperties

Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties.(Inherited from Animatable.)

System_CAPS_pubpropertyIsFrozen

Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)

System_CAPS_pubpropertyIsSealed

Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.)

System_CAPS_pubpropertyKernelType

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Gets or sets the type of blur kernel to use for the BlurBitmapEffect.

System_CAPS_pubpropertyRadius

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Gets or sets the radius used in the blur kernel. A larger radius implies more blurring.

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()

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Creates a modifiable clone of this BlurBitmapEffect, making deep copies of this object's values. When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values.

System_CAPS_pubmethodCloneCurrentValue()

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Creates a modifiable clone of this BlurBitmapEffect object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.

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_pubmethodGetOutput(BitmapEffectInput)

Obsolete.Returns the BitmapSource that results when the effect is applied to the specified BitmapEffectInput.(Inherited from BitmapEffect.)

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.)

System_CAPS_protmethodShouldSerializeProperty(DependencyProperty)

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.(Inherited from DependencyObject.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubmethodVerifyAccess()

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

NameDescription
System_CAPS_pubfieldSystem_CAPS_staticKernelTypeProperty

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Identifies the KernelType dependency property.

System_CAPS_pubfieldSystem_CAPS_staticRadiusProperty

Note: This API is now obsolete. The non-obsolete alternative is BlurEffect. Identifies the Radius dependency property.

NameDescription
System_CAPS_pubeventChanged

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

System_CAPS_noteNote

WPF bitmap effects are software rendered. Any object that applies an effect will also be rendered in software. Bitmap effects should not be applied to large visuals or animations as this can degrade performance.

BlurBitmapEffect is one of several effects that are shipped with the SDK. Other effects include:

The following illustration shows a BlurBitmapEffect applied to a visual object (in this case applied to a Button).

Screenshot: Compare button to blurred button
