[OpenLayers-Dev] ANN: OpenLayers 2.2 release candidate 1

[Bart van den Eijnden (OSGIS)]

Hey Schuyler,

I just tried the 2.2RC1, is WMS Untiled still working? I don't get any 
map anymore.

It seems OpenLayers is now requesting images larger than 2048 pixels. 
Which is over Mapserver's maximum.

Access log:
/cgi-bin/mapserv.exe?map=/lausanne/mapserver/provinces_of_holland.map&LAYERS=nl-prov&FORMAT=image/png&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application/vnd.ogc.se_inimage&SRS=EPSG:28992&BBOX=-66233.766234,341396.103896,234740.25974,491396.103896&WIDTH=2472&HEIGHT=1232 
HTTP/1.1" 200 800

If I switch back to 2.1 I get:
/cgi-bin/mapserv.exe?map=/lausanne/mapserver/provinces_of_holland.map&LAYERS=nl-prov&FORMAT=image/png&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application/vnd.ogc.se_inimage&SRS=EPSG:28992&BBOX=-166382.252559727,300000,466382.252559727,600000&WIDTH=1236&HEIGHT=586 
HTTP/1.1" 200 12231

so apparently OpenLayers now requests images by default twice as big?

I have opened up a ticket, but the code did not format well in Trac, so 
I'll paste it in this e-mail as well.

http://trac.openlayers.org/ticket/364#preview

        function mapinit(){
            map = new OpenLayers.Map( $('map'), { 'projection': 'EPSG:4326', 'units':'degrees', 'maxExtent': new OpenLayers.Bounds(-180, -90, 180, 90) , 'maxResolution':'auto'});            var layer = new OpenLayers.Layer.WMS.Untiled( "WorldGen",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers: 'WorldGen', 'format':'image/png', 'transparent':'true'} );
            layer.isBaseLayer = true;

            map.addLayers([layer]);            var layer = new OpenLayers.Layer.WMS.Untiled( "World Political",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers: 'WorldPolitical', 'format':'image/png', 'transparent':'true'} );
            layer.isBaseLayer = false;

            map.addLayers([layer]);            var layer = new OpenLayers.Layer.WMS.Untiled( "WorldGen_Outline",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers: 'WorldGen_Outline', 'format':'image/png', 'transparent':'true'} );
            layer.isBaseLayer = false;

            map.addLayers([layer]);            var layer = new OpenLayers.Layer.WMS.Untiled( "WorldRoads",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers: 'WorldRoads', 'format':'image/png', 'transparent':'true'} );
            layer.isBaseLayer = false;

            map.addLayers([layer]);            var layer = new OpenLayers.Layer.WMS.Untiled( "WorldPlaces",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers: 'WorldPlaces', 'format':'image/png', 'transparent':'true'} );
            layer.isBaseLayer = false;

            map.addLayers([layer]);            var layer = new OpenLayers.Layer.WMS.Untiled( "WorldPOI",
                "http://www2.dmsolutions.ca/cgi-bin/mswms_world?", {layers: 'WorldPOI', 'format':'image/png', 'transparent':'true'} );
            layer.isBaseLayer = false;

            map.addLayers([layer]);            map.addControl(new OpenLayers.Control.LayerSwitcher());

            map.zoomToMaxExtent();
        }

Best regards,
Bart
