/** |

* <p>Listener for doing a <i>zoom out</i> operation on the extent of the <code>ViewPort</code> of the associated {@link MapControl MapControl}
|

* object, selecting a point of the <code>MapControl</code> by a single click of the third button of the mouse.</p> |
|
| 49 |
* |
|
| 50 |
* <p>Calculates the new extent <i>r</i> with this equations: |
|
| 51 |
* <code><br> |
|
| 52 |
* ViewPort vp = mapControl.getMapContext().getViewPort();<br> |
|
| 53 |
* Point2D p2 = vp.toMapPoint(event.getPoint());<br> |
|
| 54 |
* double factor = 1/MapContext.ZOOMOUTFACTOR;<br> |
|
| 55 |
* Rectangle2D.Double r = new Rectangle2D.Double();<br> |
|
| 56 |
* double nuevoX = p2.getX() - ((vp.getExtent().getWidth() * factor) / 2.0);<br> |
|
| 57 |
* double nuevoY = p2.getY() - ((vp.getExtent().getHeight() * factor) / 2.0);<br> |
|
| 58 |
* r.x = nuevoX;<br> |
|
| 59 |
* r.y = nuevoY;<br> |
|
| 60 |
* r.width = vp.getExtent().getWidth() * factor;<br> |
|
| 61 |
* r.height = vp.getExtent().getHeight() * factor;<br> |
|
| 62 |
* vp.setExtent(r); |
|
| 63 |
* </code> |
|
| 64 |
* </p> |
|
| 65 |
* |
|
| 66 |
* <p>The ultimately extent will be an adaptation from that, calculated by the <code>ViewPort</code> |
|
| 67 |
* bearing in mind the ratio of the available rectangle.</p> |
