NameDescription
System_CAPS_pubmethod DrawingGroup

Initializes a new instance of the DrawingGroup class.

NameDescription
System_CAPS_pubproperty

Gets or sets the BitmapEffect to apply to this DrawingGroup.

System_CAPS_pubproperty

Gets or sets the region where the DrawingGroup applies its and, optionally, a BitmapSource to use as input for its .

System_CAPS_pubproperty

Gets the axis-aligned bounds of the drawing's contents. (Inherited from Drawing.)

System_CAPS_pubproperty

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

System_CAPS_pubproperty

Gets or sets the Drawing objects that are contained in this DrawingGroup.

System_CAPS_pubproperty

Gets or sets the clip region of this DrawingGroup.

System_CAPS_pubproperty

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

System_CAPS_pubproperty

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

System_CAPS_pubproperty

Gets or sets the GuidelineSet to apply to this DrawingGroup.

System_CAPS_pubproperty

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_pubproperty

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

System_CAPS_pubproperty

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

System_CAPS_pubproperty

Gets or sets the opacity of this DrawingGroup.

System_CAPS_pubproperty

Gets or sets the brush used to alter the opacity of select regions of this DrawingGroup.

System_CAPS_pubproperty

Gets or sets the Transform that is applied to this DrawingGroup.

NameDescription
System_CAPS_pubmethod Append

Opens the DrawingGroup in order to populate its . This method enables you to append additional to this DrawingGroup.

System_CAPS_pubmethod ApplyAnimationClock

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.)

System_CAPS_pubmethod ApplyAnimationClock

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.(Inherited from Animatable.)

System_CAPS_pubmethod BeginAnimation

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_pubmethod BeginAnimation

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_pubmethod CheckAccess

Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

System_CAPS_pubmethod ClearValue

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethod ClearValue

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)

System_CAPS_pubmethod Clone

Creates a modifiable deep copy of this DrawingGroup and makes deep copies of its values.

System_CAPS_pubmethod CloneCurrentValue

Creates a modifiable deep copy of this DrawingGroup object and makes deep copies of its current values.

System_CAPS_pubmethod CoerceValue

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_pubmethod Equals

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethod Freeze

Makes the current object unmodifiable and sets its property to true. (Inherited from Freezable.)

System_CAPS_pubmethod GetAnimationBaseValue

Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod GetHashCode

Gets a hash code for this DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethod GetLocalValueEnumerator

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod GetValue

Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethod InvalidateProperty

Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.)

System_CAPS_pubmethod Open

Opens the DrawingGroup in order to populate its and clears any existing .

System_CAPS_pubmethod ReadLocalValue

Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)

System_CAPS_pubmethod SetCurrentValue

Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)

System_CAPS_pubmethod SetValue

Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethod SetValue

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)

System_CAPS_protmethod ShouldSerializeProperty

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

System_CAPS_pubmethod ToString

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

System_CAPS_pubmethod VerifyAccess

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

NameDescription
System_CAPS_pubevent Changed

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

Use a DrawingGroup to combine multiple drawings into a single, composite drawing. Unlike other Drawing objects, you can apply a , , setting, , , or a to a DrawingGroup. The flexibility of this class enables you to create complex scenes.

Because DrawingGroup is also a Drawing, it can contain other DrawingGroup objects.

For more information about Drawing objects, see Drawing Objects Overview.

Freezable Features: Because it inherits from the Freezable class, the DrawingGroup class provides several special features: DrawingGroup objects can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see Freezable Objects Overview.
