HI !
i want to limit the maxScale and with the following code there is no
limit zoom level - but in the view-area.
rext = new OpenLayers.Bounds();
rext.extend(lonLatToMercator(new OpenLayers.LonLat(-26,50.5)));
rext.extend(lonLatToMercator(new OpenLayers.LonLat(34.5,66.9)));
rext.toBBOX();
map = new OpenLayers.Map ("map", {
controls:[],
//maxZoomScale: 5
restrictedExtent: rext
//maxScale: 10000
});
with the subroutine
function lonLatToMercator(ll) {
var lon = ll.lon * 20037508.34 / 180;
var lat = Math.log(Math.tan((90 + ll.lat) * Math.PI / 360)) /
(Math.PI / 180);
lat = lat * 20037508.34 / 180;
return new OpenLayers.LonLat(lon, lat);
} // -- end lonLatToMercator
when i modify the top-code to limit the zoom-level to
rext = new OpenLayers.Bounds();
rext.extend(lonLatToMercator(new OpenLayers.LonLat(-26,50.5)));
rext.extend(lonLatToMercator(new OpenLayers.LonLat(34.5,66.9)));
rext.toBBOX();
map = new OpenLayers.Map ("map", {
controls:[],
//maxZoomScale: 5, // <---------------------- add delimeter ","
restrictedExtent: rext
maxScale: 10000 // <---------------------- add parameter
});
there is a big mistake !!!
the coordinates of points will show corret but the show area of the
tiles is wrong (example: for the coordinates of north germany the tiles
of grönland will show!!!!)
can anybody help me ???
regards Jan :-)
