The BitmapSource type exposes the following members.

	Name	Description
	BitmapSource	Creates an empty BitmapSource.
	BitmapSource(Image, Int32, Int32, HighBitScaleMode)	Creates a BitmapSource from the given source image.

	HighBitScaleMode	Sets the HighBitScaleMode for scaling non-8bpp images.
	IsDownloading	Gets whether this bitmap source is downloading (never). (Overrides BitmapSourceIsDownloading.)
	IsFrozen	Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)
	IsSealed	Gets a value that indicates whether this instance is currently sealed (read-only). (Inherited from DependencyObject.)
	MaxDecodePixelHeight	Gets/sets maximal decode height.
	MaxDecodePixelWidth	Gets/sets maximal decode width.

	Width	Gets the width of the bitmap in device-independent units (1/96th inch per unit).  (Inherited from BitmapSource.)

	Name	Description
	ApplyAnimationClock(DependencyProperty, AnimationClock)	Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used. (Inherited from Animatable.)
	ApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)	Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable.)
	BeginAnimation(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.)
	BeginAnimation(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.)
	BeginInit	Begin the initialization phase.
	CheckAccess	Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
	ClearValue(DependencyProperty)	Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)
	ClearValue(DependencyPropertyKey)	Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)
	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. (Inherited from BitmapSource.)
	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. (Inherited from BitmapSource.)
	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.)
	CopyPixels(Array, Int32, Int32)	Requests pixels from this BitmapSource. (Overrides BitmapSourceCopyPixels(Array, Int32, Int32).)
	CopyPixels(Int32Rect, Array, Int32, Int32)	Requests pixels from this BitmapSource. (Overrides BitmapSourceCopyPixels(Int32Rect, Array, Int32, Int32).)
	CopyPixels(Int32Rect, IntPtr, Int32, Int32)	Requests pixels from this BitmapSource. (Overrides BitmapSourceCopyPixels(Int32Rect, IntPtr, Int32, Int32).)
	Dispose	Dispose this BitmapSource.
	EndInit	End the initialization phase and setup the object.
	Equals	Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.)
	Finalize	Finalizer. (Overrides ObjectFinalize.)
	Freeze	Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)
	GetAnimationBaseValue	Returns the non-animated value of the specified DependencyProperty. (Inherited from Animatable.)
	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.)
	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.)
	GetHashCode	Gets a hash code for this DependencyObject. (Inherited from DependencyObject.)
	GetLocalValueEnumerator	Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)
	InvalidateProperty	Re-evaluates the effective value for the specified dependency property (Inherited from DependencyObject.)
	ReadLocalValue	Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)
	SetCurrentValue	Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)
	SetValue(DependencyProperty, Object)	Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)
	SetValue(DependencyPropertyKey, Object)	Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)
	ToString	Creates a string representation of this object based on the current culture. (Inherited from ImageSource.)
	ToString(IFormatProvider)	Creates a string representation of this object based on the IFormatProvider passed in. If the provider is null, the CurrentCulture is used. (Inherited from ImageSource.)
	VerifyAccess	Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)

	Name	Description
	Changed	Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable.)
	DecodeFailed	Raised if the Source could not be decoded. (Overrides BitmapSourceDecodeFailed.)
	DownloadCompleted	Raised if the download is completed. (Overrides BitmapSourceDownloadCompleted.)
	DownloadFailed	Occurs when the bitmap content failed to download. (Inherited from BitmapSource.)
	DownloadProgress	Occurs when the download progress of the bitmap content has changed. (Inherited from BitmapSource.)

	Name	Description
	HighBitScaleModeProperty	Dependency property backing store of HighBitScaleMode.
	MaxDecodePixelHeightProperty	Dependency property backing store for MaxDecodePixelHeight property.
	MaxDecodePixelWidthProperty	Dependency property backing store for MaxDecodePixelWidth property.
	SourceProperty	Dependency property backing store for Source property.

	Name	Description
	FindVisualParentT	Finds a parent of a certain type of a this item in the visual tree. (Defined by VisualTreeHelperExtensions.)

	Name	Description
	IFormattableToString	Formats the value of the current instance using the specified format. (Inherited from ImageSource.)

Attention: do not use this class directly in any control displaying an image source. There is a bug in the WPF BitmapSource implementation throwing a NotImplemented exception in out of memory conditions in the render thread.

Makes CVB images accessible for WPF imaging. Resulting PixelFormats are either Gray8 for single plane unsigned 8bpp image or Bgr24 for all other formats (three plane 8bpp per plane images are also copied directly; all other formats are processed via the Image.ToBitmap method.

As the WPF imaging model is only designed for still image support, you need to create a new BitmapSource each time you want to display an update. Update behavior is sadly hard-coded in WPF for just three BitmapSources: WriteableBitmap, InteropBitmap and RenderTargetBitmap. Creating new BitmapSource is designed to be cheap.
