示例1: StartNextPhotoAnimation
private async Task<DoubleAnimation> StartNextPhotoAnimation(DoubleAnimation animation, Image animatedImage, bool completionFlag = false)
{
var photoindex = CurrentIndex;
animatedImage.Source = await GetNextPhotoBitmap();
//var photo = new Image { Source = await GetNextPhotoBitmap() };
var bi = animatedImage.Source as BitmapImage;
Debug.Assert(bi != null);
var photoWidth = bi.Width;
var photoHeight = bi.Height;
animation.Duration = new Duration(TimeSpan.FromSeconds(_random.Next(MinAnimateTimeSecs, MaxAnimateTimeSecs)));
animation.From = -photoHeight; // y start
animation.To = _canvasHeight + photoHeight; // y finish
// Completion handler - remove the image, start the next handler
EventHandler handler = null;
handler = async (s, e) =>
{
animation.Completed -= handler;
ScreensaverCanvas.Children.Remove(animatedImage);
await StartNextPhotoAnimation(animation, animatedImage, true);
};
animation.Completed += handler;
double xStart = _random.Next(0, (int)_canvasWidth - (int)photoWidth); ;
