For code examples in C#, C++/WinRT, and C++/CX, see WriteableBitmap.PixelBuffer.
The image source data of a WriteableBitmap is an underlying pixel buffer.
The IBuffer returned by WriteableBitmap.PixelBuffer can't be written to directly. But you can use language-specific techniques to write to the underlying pixel content in the buffer. For details, see the Remarks section of WriteableBitmap.PixelBuffer.
Some of the scenarios where you might have used a WriteableBitmap class in previous XAML frameworks can be accomplished in the Windows Runtime by using the RenderTargetBitmap class instead. For more info see RenderTargetBitmap.
|WriteableBitmap(Int32, Int32) WriteableBitmap(Int32, Int32) WriteableBitmap(Int32, Int32) WriteableBitmap(Int32, Int32)||
Initializes a new instance of the WriteableBitmap class.
|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)
|PixelBuffer PixelBuffer PixelBuffer PixelBuffer||
Gets an access for the direct buffer where each pixel of the WriteableBitmap is written to.
|PixelHeight PixelHeight PixelHeight PixelHeight||
Gets the height of the bitmap in pixels.(Inherited from BitmapSource)
|PixelHeightProperty PixelHeightProperty PixelHeightProperty PixelHeightProperty||
Identifies the PixelHeight dependency property.(Inherited from BitmapSource)
|PixelWidth PixelWidth PixelWidth PixelWidth||
Gets the width of the bitmap in pixels.(Inherited from BitmapSource)
|PixelWidthProperty PixelWidthProperty PixelWidthProperty PixelWidthProperty||
Identifies the PixelWidth dependency property.(Inherited from BitmapSource)
