I have an image in VTK that I’m viewing with vtkImageViewer2, and I want to zoom in on a point the user clicks on. I am working in Java. Does anyone know how to do this?
Thanks

I realize you ask for Java, but my experience doing this has been with c++; equivalent java syntax should work, minus the customizability.
Take a look at these examples for picking and zooming. Also, if you set the interactor style to ‘image’, the mouse wheel should cause a zoom to wherever the cursor is. You probably don’t want to do literally what you asked, but rather either do rubberband zoom or have the mousewheel for zooming. Clicking should do something, not just change the view.
