- - ### Field Detail

    - #### imageIcon

          protected javax.swing.ImageIcon imageIcon

    - #### align

          protected java.lang.Object align

      Holds the horizontal alignment for the overlay. Default is ALIGN_RIGHT. For edges, the overlay always appears in the center of the edge.

    - #### verticalAlign

          protected java.lang.Object verticalAlign

      Holds the vertical alignment for the overlay. Default is bottom. For edges, the overlay always appears in the center of the edge.

    - #### defaultOverlap

          protected double defaultOverlap

      Defines the overlapping for the overlay, that is, the proportional distance from the origin to the point defined by the alignment. Default is 0.5.

  - ### Constructor Detail

    - #### mxCellOverlay

          public mxCellOverlay(javax.swing.ImageIcon icon,
