示例1:Button_Click
privateasyncvoidButton_Click(objectsender,RoutedEventArgse)
{
using(varstream=awaitRoot.RenderToRandomAccessStream())
{
vardevice=newCanvasDevice();
varbitmap=awaitCanvasBitmap.LoadAsync(device,stream);
varrenderer=newCanvasRenderTarget(device,bitmap.SizeInPixels.Width,bitmap.SizeInPixels.Height,bitmap.Dpi);
using(vards=renderer.CreateDrawingSession())
{
varblur=newGaussianBlurEffect();
blur.BlurAmount=5.0f;
blur.Source=bitmap;
ds.DrawImage(blur);
}
stream.Seek(0);
awaitrenderer.SaveAsync(stream,CanvasBitmapFileFormat.Png);
BitmapImageimage=newBitmapImage();
image.SetSource(stream);
Blured.Source=image;
}
}
