    • 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
