[OpenLayers-Users] OpenLayers.Layer.WMS Reprojection Bounds

[Heiko Schröter]

Hi,

i need to reproject layers on the fly with a WMS server.
The map generation and reprojection works in principal, but the 'Raster' Layer needs to have the OpenLayers.Bounds adjusted to the visible active BaseLayer.
The reprojection works ok when i adjust the Bounds manually.

How can this be done automatically ?

What i want/need is something like:
'maxExtent: new OpenLayers.Bounds(new GetActive_BaseLayer_Bounds())'

<snip>
// Overlay the image
    var graphic  = new OpenLayers.Layer.WMS( "PICTURE",
                                               http_mapserver,
						{map: mapfile,
						 layers: "MAP1,PIC,GRID",
						 transparent: false },
						{
                                                 singleTile:true,
                                                 isBaseLayer: false,
// How to dynamically set OpenLayers.Bounds ???
						 maxExtent: new OpenLayers.Bounds(xxmin,yymin,xxmax,yymax) ,
   });
    layers.push(graphic);
<snap>

Regards
