Remarks

Important

You don't typically use or create a BitmapSource type directly, that's why you don't see code examples on this page. It's more common to create a BitmapImage and use that as a value. For code examples and more info, see the reference page for BitmapImage.

ImageSource and BitmapSource are intermediate base classes for BitmapImage. For more info on how to create an image source to use for Image.Source and ImageBrush.ImageSource, see Image and ImageBrush and BitmapImage.

BitmapSource derived classes

BitmapSource is the parent class for BitmapImage and WriteableBitmap.

Constructors

BitmapSource() BitmapSource() BitmapSource() BitmapSource()

Provides base class initialization behavior for BitmapSource -derived classes.

Properties

Dispatcher Dispatcher Dispatcher Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)
PixelHeight PixelHeight PixelHeight PixelHeight

Gets the height of the bitmap in pixels.

PixelHeightProperty PixelHeightProperty PixelHeightProperty PixelHeightProperty

Identifies the PixelHeight dependency property.

PixelWidth PixelWidth PixelWidth PixelWidth

Gets the width of the bitmap in pixels.

PixelWidthProperty PixelWidthProperty PixelWidthProperty PixelWidthProperty

Identifies the PixelWidth dependency property.

Methods

ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty)

Clears the local value of a dependency property.

(Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty)

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

(Inherited from DependencyObject)
GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback)

Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance.

(Inherited from DependencyObject)
SetSource(IRandomAccessStream) SetSource(IRandomAccessStream) SetSource(IRandomAccessStream) SetSource(IRandomAccessStream)

Sets the source image for a BitmapSource by accessing a stream. Most callers should use SetSourceAsync instead.

SetSourceAsync(IRandomAccessStream) SetSourceAsync(IRandomAccessStream) SetSourceAsync(IRandomAccessStream) SetSourceAsync(IRandomAccessStream)

Sets the source image for a BitmapSource by accessing a stream and processing the result asynchronously.

SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object)

Sets the local value of a dependency property on a DependencyObject.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.
