```
public class IlvHalfZoomingGraphic
extends IlvFixedSizeGraphic
```
The class IlvHalfZoomingGraphic is a wrapper class that is used to prevent a graphic object from zooming above (or below) a given maximum (or minimum) zoom level.
This class is used like the class IlvFixedSizeGraphic: You create an instance of IlvHalfZoomingGraphic that wraps another graphic object.
The behavior of the IlvHalfZoomingGraphic object is controlled by two properties: a maximum zoom level and a minimum zoom level.
When the zoom of the manager view is greater than the maximum zoom, the IlvHalfZoomingGraphic object behaves like a fixed-size graphic: its size remains constant.
When the zoom of the manager view is less than the minimum zoom, the behavior depends on the value of the grayedWhenUnzoomed property.
- If the grayedWhenUnzoomed is true, the IlvHalfZoomingGraphic object is drawn as a gray rectangle. The gray rectangle zooms out normally: it becomes smaller when the view is zoomed out.
- If the grayedWhenUnzoomed is false, the IlvHalfZoomingGraphic object behaves like a fixed-size graphic: its size remains constant.
Between minimum and maximum zoom levels, the IlvHalfZoomingGraphic object behaves just like the wrapped object: it zooms in and out normally.
You can also specify an initial zoom factor. The actual zoom factor of the view will be multiplied by this initial zoom for all transformer calculations. For example, if the initial zoom is 2, and the view's transformer is the identity, the object will behave as if the view was initially zoomed by a factor 2.
An additional feature is the alpha transparency support. If the alpha value is set below 1, the wrapped object is drawn in a transparent way even if the colors of the wrapped object are not set to transparent colors. This is useful if you want to add transparency to the entire wrapped object without changing all individual foreground, background and stroke colors of the wrapped object.

  - DELEGATE_INTERACTOR
```
public static final IlvObjectInteractor DELEGATE_INTERACTOR
```
    The delegate interactor for IlvHalfZoomingGraphic objects. Use this interactor as object interactor of the half-zooming object if the wrapped object has an object interactor. The delegate interactor forwards all events to the object interactor of the wrapped object.
    The delegate interactor is always installed by default when an instance of IlvHalfZoomingGraphic is allocated. You can call IlvGraphic.setObjectInteractor(ilog.views.IlvObjectInteractor) to install a different object interactor (use a null argument to avoid the delegation to the object interactor of the child).

```
public void setGrayedWhenUnzoomed(boolean grayedWhenUnzoomed)
```
    Specifies whether the object is drawn as a gray box when the zoom level is less than the minimum zoom, or if it is drawn at its minimum size.
    The default value of true.
    Note: If this property is set to false, the object is not zoomable any more (that is to say, zoomable() returns false), and it will be handled less efficiently by JViews.
    
    Parameters:
    
    grayedWhenUnzoomed - If true, the object is drawn as a gray box when the zoom level is less than the minimum zoom, and the gray box keeps unzooming as the zoom level decreases. If false, the object is always drawn at its minimum size whenever the zoom level is below the minimum zoom.
  - isGrayedWhenUnzoomed
```
public boolean isGrayedWhenUnzoomed()
```
    Returns the flag specifying whether the object is drawn as a gray box when the zoom level is less than the minimum zoom, or if it is drawn at its minimum size.
  - setRotatable
```
public void setRotatable(boolean flag)
```
    Sets whether the object supports rotation. If this wrapper has the rotation support disabled, the object always stays in upright position, even if the wrapped object would support rotation. The rotation factor is not delegated to the wrapped object. If this wrapper has the rotation support enabled, it depends on the wrapped object how it behaves under rotation. If the wrapped object also supports rotation, it will rotate normally.
    The default value is true.

```
public void setAlpha(float alpha)
```
    Changes the alpha value of this object. The alpha composition value is used to render the wrapped object in a transparent way. The value must be in the range of [0.0, 1.0], the value of 1 means that the object is not transparent.
    
    Parameters:
    
    alpha - The new transparency level in the range [0.0, 1.0].

```
public void setAlphaBufferEnabled(boolean enable)
```
    Sets whether an additional buffer is used to draw the object when the alpha composition value is not 1.0. This option has no effect if the alpha value is 1.0. If the alpha buffer is enabled, the drawing routine first draws into the alpha buffer and then copies the result into the drawing. This results into a transparent display of this object that is visually closer to its nontransparent display. If the alpha buffer is disabled, drawing is slightly faster, but the transparent display may differ from the nontransparent display. The alpha buffer is enabled by default.
    
    Parameters:
    
    enable - Whether the alpha buffer is enabled.

  - computeTransformer
```
public IlvTransformer computeTransformer(IlvTransformer t)
```
    Computes the transformer used to draw this object based on the specified transformer. For example, when this object's draw method is called, the computeTransformer method computes a modified transformer that takes into account the minimum and maximum zoom levels. Then, the new transformer is passed to the draw method of the superclass to actually draw the object.
    
    Parameters:
    
    t - The manager view transformer.

protected IlvRect unzoomedBBox()
```
    Returns the bounding box used when the object is drawn below the minimum zoom level. The returned rectangle must be in manager coordinates, and it will be unzoomed according to the view transformer.
    The default implementation returns boundingBox(null). If you redefine this method, and if you return a bigger rectangle than the default implementation, then the object is not zoomable any more, and you must also redefine zoomable() to return false.
  - getReferenceZoom
```
protected double getReferenceZoom()
```
    Returns the reference zoom. This method can be overridden to change the reference zoom dynamically without having to set the initial zoom level on all the half-zooming objects of a view.
    The default implementation returns 1.0.
  - zoomable
```
public boolean zoomable()
```
    Returns true if this object is zoomable, and false otherwise. Whether this object is zoomable depends on whether the wrapped object is zoomable and on the parameters of this half-zooming object.
    
    Overrides:
    
    zoomable in class IlvFixedSizeGraphic

                          IlvRect trect,
                          IlvTransformer t)
```
    Tests whether a rectangle overlaps the object. Calls intersects on the referenced object.
    
    Overrides:
    
    intersects in class IlvFixedSizeGraphic
    
    Parameters:
    
    rect - The rectangle to be tested.
    
    trect - The rectangle rect transformed by the transformer t.
    
    t - The transformation applied to the object when it was drawn.
    
    Returns:
    
    true if the rectangle overlaps this graphic object.

public boolean inside(IlvRect rect,
                      IlvRect trect,
                      IlvTransformer t)
```
    Tests whether a rectangle contains the object. Calls inside on the referenced object.
    
    Overrides:
    
    inside in class IlvFixedSizeGraphic
    
    Parameters:
    
    rect - The rectangle to be tested.
    
    trect - The rectangle rect transformed by the transformer t.
    
    t - The transformation that was applied to the object when it was drawn.

```
public IlvPoint getIntersectionWithOutline(IlvPoint innerPoint,
                                           IlvPoint outerPoint,
                                           IlvTransformer t)
```
    Returns the intersection of the line segment from inner point to outer point with the shape of the graphic object. This method is used the clip links against the shape of the node. The implementation of this method must be robust with respect to the input points: Even if innerPoint is not inside the graphic object, or if outerPoint is not outside the graphic object, it must return a valid point. For instance, if there is no intersection, it can return the start point.
    
    Overrides:
    
    getIntersectionWithOutline in class IlvFixedSizeGraphic
    
    Parameters:
    
    innerPoint - A point usually inside the graphic object, given in manager view coordinates.
    
    outerPoint - A point usually outside of the graphic object, given in manager view coordinates.
    
    t - The transformation used to draw the object.

  - getToolTipText
```
public String getToolTipText(IlvPoint p,
                             IlvTransformer t)
```
    Returns the tooltip text to display when the mouse pointer is at a specified location inside the graphic object. It tries to retrieve the tooltip text on the referenced object. If this fails, it tries to retrieve the tooltip text on this object.
    Note that you must enable the tooltip mechanism for the manager view by calling the static method IlvToolTipManager.registerView(ilog.views.IlvManagerView).
    
    Overrides:
    
    getToolTipText in class IlvFixedSizeGraphic
    
    Parameters:
    
    p - The location of the mouse (in view coordinates).
    
    t - The transformer that converts the coordinate system of this object (the manager coordinates) into the coordinate system of the manager view in which the tooltip is about to be displayed (the view coordinates).
    
    Returns:
    
    The tooltip at point p for transformation t, or null if no tooltip should be displayed.

                               IlvPopupMenuManager popupManager)
```
    Returns the Swing pop-up menu to display when the pop-up is triggered while the mouse pointer is at a specified location inside the graphic object. It tries to retrieve the pop-up menu on the referenced object. If this fails, it tries to retrieve the pop-up menu on this object.
    Note that you must enable the pop-up menu mechanism for the manager view by calling the static method IlvPopupMenuManager.registerView(ilog.views.IlvManagerView).
    
    Overrides:
    
    getPopupMenu in class IlvFixedSizeGraphic
    
    Parameters:
    
    p - The location of the mouse (in view coordinates).
    
    t - The transformer that converts the coordinate system of this object (the manager coordinates) into the coordinate system of the manager view in which the tooltip is about to be displayed (the view coordinates).
    
    view - The manager view that triggered the pop-up menu.
    
    popupManager - The pop-up menu manager.
    
    Returns:
    
    The Swing pop-up menu, which can be null.
