Coordinates(x,y) values and pixel values under the cursor using vtk.js

I am trying to display the coordinates(x,y) under the mouse cursor (on mousemove event) and also the pixel value using vtk.js on a vtkImageSlice. Is there any widget that already does that ?
I know how to do that using javascript but want to know if it is possible in vtk.js .

Thanks in advance.

You will have to do it in JS and query the pixel value with maybe a PointPicker on the vtkImageSlice.
