在ScrollViewer中以编程方式对缩放因子进行动画处理

Question

Is there a way that I can animate changing the zoom factor of a ScrollViewer for Windows Runtime?

I'd like to be able to have an image inside one respond to a tapped event by returning to a default zoom of 1. While it seems that in Windows 8.1 Change View lets you animate the scrolling, not the zooming I'd like to be able to animate both.

The best solution I found was to take a part of the WinRT XAML Toolkit which has a functioning example and an extension for ScrollViewer which does just this.

Also by setting the ScrollViewer to have size of Auto and simply re-sizing the width properties of whatever element is contained within you can achieve largely the same effect.
