<h1>ol-ext: Overview map control</h1>
|
|
</a>
|
|
<div class="info">
|
|
The <i>ol.control.Overview</i> create an overview similar to the <i>ol.control.overview</i>.
|
|
<br/>
|
|
The main differences is that you can limit the zoom level on the overview and force the overview to be oriented north.
|
|
<ul>
|
|
<li>
|
|
Limiting the min zoom of the overview will magnify the map.
|
|
</li>
|
|
<li>
|
|
Limiting the max zoom avoid to zoom in the overview and draw the position as a point on it when extent is too small.
|
|
</li>
|
|
<li>
|
|
You can use the <i>style</i> option to choose the style of the box drawn on the overview.
|
|
If the box is too small a point will be drawn instead (ol.style.Image of the style).
|
|
</li>
|
|
</ul>
|
|
Click on the overview map to move the center of the map to that point.
|
|
The <i>elastic</i> option move the map with an elastic animation.
