[OpenLayers-Dev] EPSG:41001

[Gilbert, Antoine]

For example a tile 256x256 is assumed to have long lat ratio 1x1, but in
a map using 41001 this long lat ratio does not make a square. That's why
I don't understand the 1x1 concept

Here is an example of URL I build with the bounds

http://localhost:8084/TestOpenLayersWithPNS/ImageServlet?width=256&heigh
t=256&bbox=-71.267246,46.846768,-71.25626,46.857754

Here is my javascript/html

var lon = -71.223;
var lat = 46.8159;
var zoom = 15;
var map, layer;
function init(){
	map = new OpenLayers.Map("map", {maxExtent: new
OpenLayers.Bounds(-20037508.34, -20037508.34, 20037508.34, 20037508.34),
units: 'meters', projection: "EPSG:41001"});
	layer = new OpenLayers.Layer.PnsImage2( "OpenLayers PnsImage2", 
                        baseHREF+"ImageServlet", {layers: 'basic',
projection: "EPSG:41001"});
      map.addLayer(layer);
      map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
      map.addControl( new OpenLayers.Control.PanZoomBar() );
}

Projections make the ratio of the bounds 1:1. Can you give example HTML
and an example tile URL you are getting?
