BitmapSource Members

.NET Framework 3.5

Represents a single, constant set of pixels at a certain size and resolution.

The BitmapSource type exposes the following members.

  NameDescription
Protected method BitmapSource Initializes a new instance of the BitmapSource class.
Top
  NameDescription
Public method ApplyAnimationClock Overloaded. Animates the specified DependencyProperty using the specified AnimationClock.
Public method BeginAnimation Overloaded. Applies an animation to the specified DependencyProperty.
Public method CheckAccess Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Protected method CheckIfSiteOfOrigin Checks whether the bitmap source content is from a known site of origin. This method is used to make sure that pixel copying operations are safe.
Public method ClearValue Overloaded. Clears the local value of a property.
Public method Clone Creates a modifiable clone of this BitmapSource, 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.
Protected method CloneCore Makes this instance a deep copy of the specified BitmapSource. 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. (Overrides Freezable.CloneCore(Freezable).)
Public method CloneCurrentValue Creates a modifiable clone of this BitmapSource object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.
Protected method CloneCurrentValueCore Makes this instance a modifiable deep copy of the specified BitmapSource using current property values. Resource references, data bindings, and animations are not copied, but their current values are. (Overrides Freezable.CloneCurrentValueCore(Freezable).)
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 dependency property as it exists on the calling DependencyObject. (Inherited from DependencyObject.)
Public method CopyPixels Overloaded. Copies the bitmap pixel data.
Public method Static member Create Overloaded. Creates a new BitmapSource that has the specified properties and options.
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 the Freezable derived class. (Inherited from Freezable.)
Public method Equals Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method Freeze Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)
Protected method FreezeCore Makes an instance of BitmapSource or a derived class immutable. (Overrides Animatable.FreezeCore(Boolean).)
Public method GetAnimationBaseValue Returns the non-animated value of the specified DependencyProperty. (Inherited from Animatable.)
Public method 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.)
Protected method GetAsFrozenCore Makes this instance a clone of the specified BitmapSource object. (Overrides Freezable.GetAsFrozenCore(Freezable).)
Public method 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.)
Protected method GetCurrentValueAsFrozenCore Makes this instance a frozen clone of the specified BitmapSource. Resource references, data bindings, and animations are not copied, but their current values are. (Overrides Freezable.GetCurrentValueAsFrozenCore(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.)
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.
Protected method OnPropertyChanged Overrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a changing dependency property of type Freezable. (Inherited from Freezable.)
Public method ReadLocalValue Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)
Protected method ReadPreamble Ensures that the Freezable is being accessed from a valid thread. Inheritors of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties. (Inherited from Freezable.)
Public method SetValue Overloaded. Sets the local value of a dependency property.
Protected method ShouldSerializeProperty Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject.)
Public method ToString Overloaded. Creates a string representation of this object based on the current culture.
Public method VerifyAccess Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Protected method WritePostscript Raises the Changed event for the 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 inheritors should call this method at the beginning of any API that writes to data members that are not dependency properties. (Inherited from Freezable.)

  NameDescription
Public property CanFreeze Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.)
Public property DependencyObjectType Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.)
Public property Dispatcher Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)
Public property DpiX Gets the horizontal dots per inch (dpi) of the image.
Public property DpiY Gets the vertical dots per inch (dpi) of the image.
Public property Format Gets the native PixelFormat of the bitmap data.
Public property HasAnimatedProperties Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties. (Inherited from Animatable.)
Public property Height Gets the height of the source bitmap in device-independent units (1/96th inch per unit). (Overrides ImageSource.Height.)
Public property IsDownloading Gets a value that indicates whether the BitmapSource content is currently downloading.
Public property IsFrozen Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)
Public property IsSealed Gets a value that declares whether this instance is currently read-only. (Inherited from DependencyObject.)
Public property Metadata Gets the metadata that is associated with this bitmap image. (Overrides ImageSource.Metadata.)
Public property Palette Gets the color palette of the bitmap, if one is specified.
Public property PixelHeight Gets the height of the bitmap in pixels.
Public property PixelWidth Gets the width of the bitmap in pixels.
Public property Width Gets the width of the bitmap in device-independent units (1/96th inch per unit). (Overrides ImageSource.Width.)

  NameDescription
Public event Changed Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable.)
Public event DecodeFailed Occurs when the image fails to load, due to a corrupt image header.
Public event DownloadCompleted Occurs when the bitmap content has been completely downloaded.
Public event DownloadFailed Occurs when the bitmap content failed to download.
Public event DownloadProgress Occurs when the download progress of the bitmap content has changed.
