10. <ScrollViewer >... VerticalSnapPointsType="Mandatory" VerticalSnapPointsAlignment="Near"

11. <ScrollViewer > HorizontalScrollMode="Rails" VerticalScrollMode="Rails"

12. //Setting min/max zoom factor svContent.MinZoomFactor =.5f; svContent.MaxZoomFactor = 8; //Adding zoom snap-points svContent.ZoomSnapPoints.Add(.5f); svContent.ZoomSnapPoints.Add(1); svContent.ZoomSnapPoints.Add(4); svContent.ZoomSnapPoints.Add(8);

13. Using the touch API for advanced touch interaction

15. private void Holding(object sender, HoldingEventArgs e) { switch (e.HoldingState) { case HoldingState.Started: { //perform action }; case HoldingState.Canceled: { //undo action }; case HoldingState.Completed: { //commit action }; }

20. PointerDevice Pointer PointerPoint

21. <Image PointerPressed="PointerPressed" PointerReleased="PointerReleased" PointerMoved="PointerMoved" /> PointerCanceled="PointerReleased"

22. private void PointerMoved(object sender, PointerEventArgs e) { PointerPoint pt = e.GetCurrentPoint(LayoutRoot);... Line l = new Line() {... X2 = pt.Position.X, Y2 = pt.Position.Y, StrokeThickness = pt.Properties.Pressure, };... }
