      • zoomed

        public void zoomed​(double[][] bounds)
        Description copied from class: ZoomRegion
        Callback which will be invoked when a zoom invoked on this region has been completed successfully. Elements of the parameter array are two-element arrays giving (lower, upper) bounds in one or more dimensions, according to the type of region. The units should normally be dimensionless: a range of (0,1) indicates the same range as is currently contained by the display region. Bounds may be larger or smaller than the (1,0) interval.
        Specified by:
        zoomed in class ZoomRegion
        Parameters:
        bounds - array of (lower, upper) zoom bounds
