[OpenLayers-Users] howto fix overviewmap

[Lars Lingner]

Hello,

in my application I defined an overviewmap like this:

var ovmap = new OpenLayers.Layer.Image( "ovmap",
   "/img/ovmap.png",
   new OpenLayers.Bounds(485455.0625, 109856,512934.34375, 135514),
   new OpenLayers.Size(178,162)
);

var ov_options = {
   layers: [ovmap],
   mapOptions: {
       numZoomLevels: 1,
       autoPan: false,
//                        alwaysInRange: true,
       restrictedExtent: new OpenLayers.Bounds(485455.0625,
109856,512934.34375, 135514 )
   },
   size: new OpenLayers.Size(178, 162),
};

and add ov_options to the control:

new OpenLayers.Control.OverviewMap( ov_options )


The image is shown but if I zoom in, the overviewmap gets recenterd.
What kind of mistake am I doing?

Setting restrictedExtent also doesn't work. Should I resize my image to
an more appropriate size or doesn't the size matter?

Thanks in advance for any hints.
