Remarks

ImageViewerZoomAtInteractiveMode derives from ImageViewerInteractiveMode and subscribes to the following events of the InteractiveService:

When a valid Tap event occurs and InteractiveEventArgs.IsHandled is false, this interactive mode will start working and set InteractiveEventArgs.IsHandled to true.

This interactive mode uses ImageViewer.Zoom to zoom the image inside the viewer based on the tap event. If the value of ScaleFactor is greater than 1, then the viewer will zoom the image in. If the value of ScaleFactor is less than 1, then the viewer will zoom the image out.
