public sealed class OuterGlowBitmapEffect : BitmapEffect
<OuterGlowBitmapEffect .../>

The OuterGlowBitmapEffect type exposes the following members.

  NameDescription
Public methodOuterGlowBitmapEffectNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Initializes a new instance of the OuterGlowBitmapEffect class.
Top

  NameDescription
Public propertyCanFreezeGets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.)
Public propertyDependencyObjectTypeGets the DependencyObjectType that wraps the CLR type of this instance.  (Inherited from DependencyObject.)
Public propertyDispatcherGets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)
Public propertyGlowColorNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Gets or sets the color of the halo glow.
Public propertyGlowSizeNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Gets or sets the thickness of the halo glow.
Public propertyHasAnimatedPropertiesGets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties. (Inherited from Animatable.)
Public propertyIsFrozenGets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)
Public propertyIsSealedGets a value that indicates whether this instance is currently sealed (read-only). (Inherited from DependencyObject.)
Public propertyNoiseNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Gets or sets the graininess of the halo glow.
Public propertyOpacityNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Gets or sets the degree of opacity of the halo glow.

  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)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.)
Public methodCheckAccessDetermines 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 methodCloneNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Creates a modifiable clone of this OuterGlowBitmapEffect, 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.
Public methodCloneCurrentValueNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Creates a modifiable clone of this OuterGlowBitmapEffect object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.
Public methodCoerceValueCoerces 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.)
Public methodEqualsDetermines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.)
Public methodFreeze()Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)
Public methodGetAnimationBaseValueReturns the non-animated value of the specified DependencyProperty. (Inherited from Animatable.)
Public methodGetAsFrozenCreates 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.)
Public methodGetCurrentValueAsFrozenCreates 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.)
Public methodGetHashCodeGets a hash code for this DependencyObject. (Inherited from DependencyObject.)
Public methodGetLocalValueEnumeratorCreates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)
Public methodGetOutput Obsolete. Returns the BitmapSource that results when the effect is applied to the specified BitmapEffectInput. (Inherited from BitmapEffect.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)
Public methodInvalidatePropertyRe-evaluates the effective value for the specified dependency property (Inherited from DependencyObject.)
Public methodReadLocalValueReturns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)
Public methodSetCurrentValueSets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)
Public methodSetValue(DependencyProperty, Object)Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)
Public methodSetValue(DependencyPropertyKey, Object)Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)
Protected methodShouldSerializePropertyReturns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodVerifyAccessEnforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)

  NameDescription
Public eventChangedOccurs when the Freezable or an object it contains is modified. (Inherited from Freezable.)

  NameDescription
Public fieldStatic memberGlowColorPropertyNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Identifies the GlowColor dependency property.
Public fieldStatic memberGlowSizePropertyNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Identifies the GlowSize dependency property.
Public fieldStatic memberNoisePropertyNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Identifies the Noise dependency property.
Public fieldStatic memberOpacityPropertyNote: This API is now obsolete. The non-obsolete alternative is BlurEffect. Identifies the Opacity dependency property.

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 because this can degrade performance.

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

The following illustration shows an OuterGlowBitmapEffect applied to a visual object (in this case applied to a TextBox).

The following illustrations show the effect of several basic properties of OuterGlowBitmapEffect.

  • The GlowSize property specifies the size of the halo glow:
