How can I access data from renderWindow?

Hello There,

I want to make the slicer showed in the “Red” widget curve.


In order to do this, I am trying to get slice data before it was rendered.
I have no idea how to do this, I can only get the “renderWindow” from each “sliceView”.
How can I access the slice data and process it?“Red”).sliceView().renderWindow()
