  • Constructor Details

    • SurfaceZoomRegionList

      public SurfaceZoomRegionList(uk.ac.starlink.ttools.plot.SurfacePlot plot)
      Constructor.
      Parameters:
      plot - plot for zooming

  • Method Details

    • requestZoom

      protected abstract void requestZoom(double[][] bounds)
      Invoked when the user indicates by mouse gestures that a zoomed view is wanted. The elements of the bounds array are 2-element double[] arrays giving (lower, upper) bounds of the range along each axis which is required. A null element indicates that no zooming along that axis is required. Boundary values are in data coordinates.
      Parameters:
      bounds - zoom request details

    • size

      public int size()
      Specified by:
      size in interface Collection<ZoomRegion>
      Specified by:
      size in interface List<ZoomRegion>
      Specified by:
      size in class AbstractCollection<ZoomRegion>

    • get

      public ZoomRegion get(int index)
      Specified by:
      get in interface List<ZoomRegion>
      Specified by:
      get in class AbstractList<ZoomRegion>

    • reconfigure

      public void reconfigure()
      Configures this list appropriately for the current state of the plot. Should be called whenever plot geometry changes (including before first use).
