捏放大和平移

Question

I have figured out, that I can use ScrollViewer in iOS and in Android I can use this ScaleImageView from XamarinAndroidToolkit .

But what can I use for UWP?

Answer 1

You should be able to use ScrollViewer for this purpose as well. You will however need to enable zooming and both scroll bars for the control. Vertical scroll bar should be set to Auto by default, but horizontal is by default disabled. The same goes for the zoom mode. If you want to hide the scroll bars, you can do so after explicitly enabling the scrolling.

<ScrollViewer ZoomMode="Enabled" 
              HorizontalScrollMode="Auto"                
              VerticalScrollMode="Auto"  
              VerticalScrollBarVisibility="Hidden" 
              HorizontalScrollBarVisibility="Hidden"
              >
   ...
</ScrollViewer>
