[OpenLayers-Users] Bounding Box and Orthographic projection "AUTO2:42003,1,-75.,0."

[Joaquín Rodriguez-Guerra Urcelay]

Dear list,

I am having a bit of troube trying to set the bbox parameter in a wms request.

I want openlayers to request the following url (which works) (image in orthographic projection similar to the ones in http://glmapserver.sourceforge.net/test/layer_test.html)

http://localhost:8080/cgi-bin/mywms?LAYERS=mars_orbital&VERSION=1.3.0&EXCEPTIONS=INIMAGE&SERVICE=WMS&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&CRS=AUTO2%3A42003%2C1%2C-75.%2C0.&BBOX=-7800000.,-7800000.,7800000.,7800000.&WIDTH=512&HEIGHT=256

But all I can get is this (which does not work)

http://localhost:8080/cgi-bin/mywms?LAYERS=mars_orbital&VERSION=1.3.0&EXCEPTIONS=INIMAGE&SERVICE=WMS&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&CRS=AUTO2%3A42003%2C1%2C-75.%2C0.&BBOX=-360,-180,360,180&WIDTH=512&HEIGHT=256

The only difference is the bbox parameter. Openlayers keeps requesting BBOX=-360,-180,360,180 when I need BBOX=-7800000.,-7800000.,7800000.,7800000

I dont know how to set the extent, this is what I tried : 

        function init(){
            var options = {
		projection: new OpenLayers.Projection("AUTO2:42003,1,-75.,0."),
                units: "m",
		maxExtent: new OpenLayers.Bounds(-7800000,-7800000,7800000,7800000) 
            };
            map = new OpenLayers.Map('map',options);
            var ol_wms = new OpenLayers.Layer.WMS(
                "OpenLayers WMS",
                "http://localhost:8080/cgi-bin/mywms", 
		{layers: 'mars_orbital',VERSION: "1.3.0"},
		{singleTile: true, ratio: 1});
            map.addLayer(ol_wms);
            map.addControl(new OpenLayers.Control.LayerSwitcher());
	    map.zoomToMaxExtent();       

Thanks in advance!!
