How to use the pixi-filters.ReflectionFilter function in pixi-filters

this.timeout=null;
    this.progress={
      puzzles:[]
    };

    this.width=config.width;
    this.height=config.height;
    this.parent=null;
    if(config.parent!=undefined) this.parent=config.parent;
    this.autoResize=true;
    if(config.autoResize!=undefined) this.autoResize=config.autoResize;

    this.app=new PIXI.Application(config.width,config.height,{autoResize: true,resolution: devicePixelRatio});
    this.OldFimFilter=new filters.OldFilmFilter();
    this.GodRayFilter=new filters.GodrayFilter();
    this.ReflectionFilter=new filters.ReflectionFilter({
      mirror:false,
      boundary:0,
      amplitude:[2,2],
      waveLength:[100,100]
    }
    );

    //Z-Order
    this.app.stage = new PIXI.display.Stage();
    this.sortGroup= new PIXI.display.Group(0, true);
    this.sortGroup.on('sort', function (sprite) {

    });
    this.onTopGroup = new PIXI.display.Group(1,false);
    this.UIGroup = new PIXI.display.Group(2,false);
    this.layer=new PIXI.display.Layer(this.sortGroup);
