Field Detail

### graphComponent

    protected mxGraphComponent graphComponent

  Reference to the enclosing graph instance.

### steps

    protected int steps

  Specifies the maximum number of steps for the morphing. Default is 6.

### step

    protected int step

  Counts the current number of steps of the animation.

### ease

    protected double ease

  Ease-off for movement towards the given vector. Larger values are slower and smoother. Default is 1.5.

### origins

    protected java.util.Map<java.lang.Object,mxPoint> origins

  Maps from cells to origins.

### cells

    protected java.lang.Object[] cells

  Optional array of cells to limit the animation to.

### dirty

    protected transient mxRectangle dirty

### preview

    protected transient mxCellStatePreview preview

Constructor Detail

### mxMorphing

    public mxMorphing(mxGraphComponent graphComponent)

  Constructs a new morphing instance for the given graph.

### mxMorphing

    public mxMorphing(mxGraphComponent graphComponent,
                      int steps,
                      double ease,
                      int delay)
