    this.resliceMapper = vtkImageResliceMapper.newInstance();
    this.reslicePlane = vtkPlane.newInstance();
    this.reslicePlane.setNormal(ViewType[2]);

    // this.imageInteractor = vtkInteractorStyleImage.newInstance();
    // this.renderWindow
    //   .getRenderWindow()
    //   .getInteractor()
    //   .setInteractorStyle(this.imageInteractor);
    this.renderer.addActor(this.imageResliceActor);

I have created vtkImageSlice actor with “vtkImageMapper”

Now I want to pick a point on that actor, Here is my code for picker

    const picker = vtkCellPicker.newInstance();
    picker.setPickFromList(true);
    picker.initializePickList();
    picker.setTolerance(0);
    return picker;

But I am not getting any points with picker.

    this.imagePicker.pick(mousePosition, this.renderer);
    const pickedPositions = this.imagePicker.getPickedPositions();
