wpf Supporting Video Streaming and Pixel Array Assignment to an Image Control
Parameters
| Parameters | Details |
|---|---|
| PixelHeight (System.Int32) | The height of the image in units of image pixels |
| PixelWidth (System.Int32) | The width of the image in units of image pixels |
| PixelFormat (System.Windows.Media.PixelFormat) | The width of the image in units of image pixels |
| Pixels | Anything which implements IList<T>- including the C# byte array |
| DpiX | Specifies the horizontal Dpi - Optional |
| DpiY | Specifies the vertical Dpi - Optional |
Remarks
- Make sure to reference the System.Windows.Interactivity assembly, so that the XAML Parser will recognize the xmlns:i declaration.
- Note that the xmlns:b statement matches the namespace where the behavior implementation resides
- Example assumes working knowledge of binding expressions and XAML.
- This behavior supports assigning pixels to an image in the form of a byte array - even though the Dependency Property type is specified as an IList. This works since the C# byte array implements the IList interface.
- Behavior achieves very high performance, and can be used for Video Streaming
- Do not assign the image's Source Dependency Property- bind to the Pixels Dependency Property instead
- The Pixels, PixelWidth, PixelHeight and PixelFormat properties must be assigned for the pixels to be rendered
- Order of Dependency Property assignment does not matter
