JavaFX Limits to zoomfunction

[hello_123321]

Hello

I try to implement a zoomIn and zoomOut function on a Scrollpane including an ImageView. Now i have the following Problem: I don't have any limits when zooming or paning. How can I implement borders to my scrollpane. I'd like to define borders around the image.

Screenshot as an example of the problem:


What I like to have: The picture shoud fit my window.


Can anyone help me with this? Code is in the appendix.
Thanks

There is also the gesture pane, that supports zooming out of the box (via touch (pinch to zoom) & mouse (ctrl+scroll wheel)) and you can push everything into it, AFAIK.

#edit: actually I used the pinch to zoom feature on a mobile app I'd written with JavaFXPorts... Works as expected!
