(see also Protected Methods )
  Name Description
Public method ApplyAnimationClock  Overloaded. Animates the specified DependencyProperty using the specified AnimationClock. (inherited from Animatable)
Public method BeginAnimation  Overloaded. Applies an animation to the specified DependencyProperty. (inherited from Animatable)
Public method BeginInit Signals the start of the BitmapImage initialization.
Public method CheckAccess  Determines whether the calling thread has access to this DispatcherObject. (inherited from DispatcherObject)
Public method ClearValue  Overloaded. Clears the local value of a property. (inherited from DependencyObject)
Public method Clone Creates a modifiable clone of this BitmapImage, 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 method CloneCurrentValue Creates a modifiable clone of this BitmapImage 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 method CoerceValue  Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the property on this type. (inherited from DependencyObject)
Public method CopyPixels  Overloaded. Copies the bitmap pixel data. (inherited from BitmapSource)
Public method Static Create  Overloaded. Creates a new BitmapSource that has the specified properties and options. (inherited from BitmapSource)
Public method EndInit Signals the end of the BitmapImage initialization.
Public method Equals  Overloaded. Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (inherited from DependencyObject)
Public method Freeze  Overloaded. Makes a Freezable unmodifiable and sets its IsFrozen property to true, or determines whether the specified Freezable can be made unmodifiable. (inherited from Freezable)
Public method GetAnimationBaseValue  Returns the non-animated value of the specified DependencyProperty. (inherited from Animatable)
Public method GetAsFrozen  Creates a frozen copy of this Freezable , using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (inherited from Freezable)
Public method GetCurrentValueAsFrozen  Creates a frozen copy of this Freezable , using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (inherited from Freezable)
Public method GetHashCode  Gets a hash code for this DependencyObject. (inherited from DependencyObject)
Public method GetLocalValueEnumerator  Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (inherited from DependencyObject)
Public method GetType  Gets the Type of the current instance. (inherited from Object)
Public method GetValue  Returns the current effective value of a dependency property on this instance of a DependencyObject. (inherited from DependencyObject)
Public method InvalidateProperty  Re-evaluates the effective value for the specified dependency property (inherited from DependencyObject)
Public method ReadLocalValue  Returns the local value of a dependency property, if it exists. (inherited from DependencyObject)
Public method Static ReferenceEquals  Determines whether the specified Object instances are the same instance. (inherited from Object)
Public method SetValue  Overloaded. Sets the local value of a dependency property. (inherited from DependencyObject)
Public method Static ShouldSerializeStoredWeakReference  This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code. (inherited from Animatable)
Public method ToString  Overloaded. Creates a string representation of this object based on the current culture. (inherited from ImageSource)
Public method VerifyAccess  Enforces that the calling thread has access to this DispatcherObject. (inherited from DispatcherObject)

  Name Description
Protected method CloneCore  Makes this instance a clone (deep copy) of the specified Freezable using base (non-animated) property values. (inherited from Freezable)
Protected method CloneCurrentValueCore  Makes this instance a modifiable clone (deep copy) of the specified Freezable using current property values. (inherited from Freezable)
Protected method CreateInstance  Initializes a new instance of the Freezable class. (inherited from Freezable)
Protected method CreateInstanceCore  When implemented in a derived class, creates a new instance of that Freezable subclass. (inherited from Freezable)
Protected method Finalize  Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (inherited from Object)
Protected method Static Freeze  Overloaded. Makes a Freezable unmodifiable and sets its IsFrozen property to true, or determines whether the specified Freezable can be made unmodifiable. (inherited from Freezable)
Protected method FreezeCore  Makes this Freezable object unmodifiable or determines whether it can be made unmodifiable. (inherited from Freezable)
Protected method GetAsFrozenCore  Makes this instance a frozen clone of the specified Freezable using base (non-animated) property values. (inherited from Freezable)
Protected method GetCurrentValueAsFrozenCore  Makes this instance a frozen clone of the specified Freezable. If this object has animated dependency properties, their current animated values are copied. (inherited from Freezable)
Protected method MemberwiseClone  Creates a shallow copy of the current Object. (inherited from Object)
Protected method OnChanged  Called when the current Freezable object is modified. (inherited from Freezable)
Protected method OnFreezablePropertyChanged  Overloaded. Ensures that appropriate context pointers are established for a data member of type DependencyObject that has just been modified. (inherited from Freezable)
Protected method OnPropertyChanged  Overrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a dependency property of type Freezable changing. (inherited from Freezable)
Protected method ReadPreamble  Ensures that this Freezable is being accessed from a valid thread. Implementers of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties. (inherited from Freezable)
Protected method ShouldSerializeProperty  Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (inherited from DependencyObject)
Protected method WritePostscript  Raises the Changed event for this 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)
Protected method WritePreamble  Verifies that the Freezable is not frozen and that it is being accessed from a valid threading context. Freezable implementers should call this method at the beginning of any API that writes to data members that are not dependency properties. (inherited from Freezable)

  Name Description
Public event Changed  Occurs when this Freezable or an object it contains is modified. (inherited from Freezable)
Public event DownloadCompleted  Occurs when the bitmap content has been completely downloaded.(inherited from BitmapSource)
Public event DownloadFailed  Occurs when the bitmap content failed to download.(inherited from BitmapSource)
Public event DownloadProgress  Occurs when the download progress of the bitmap content has changed.(inherited from BitmapSource)
