WriteableBitmap Sample

  • Article

Here's the source to the WriteableBitmap sample I showed at Mix. The sample uses WriteableBitmap to take a "snapshot" of the running video to make a thumbnail. Click on the image below to run the sample. When running the sample, click on the running video to create a thumbnail. You can find the video for this sample here.

The demo shows the following new Silverlight 3 features:

 

· WriteableBitmap

· WrapPanel (new SDK control)

    Hi, There is a strange behaviour with the writeablebitmap. If I assign the writeablebitmap directly to the source of an image, it works (well, depending on the render tree, but that's another problem) : WriteableBitmap wb = new WriteableBitmap(30, 40, PixelFormats.Bgr32); wb.Render(this.sourceImage, new MatrixTransform()); image1.Source = wb; But if I try to read directly the value of the WriteableBitmap pixels, it throws an exception : WriteableBitmap wb = new WriteableBitmap(30, 40, PixelFormats.Bgr32); wb.Render(this.sourceImage, new MatrixTransform()); int color = wb[0]; Is it a normal behaviour or is it because the writeablebitmap isn't yet fully implemented ?
