[OpenLayers-Users] Changing map max extent on the fly

[Bart van den Eijnden]

Hi strk,

maybe you can look at:

http://dev.openlayers.org/sandbox/elemoine/reproject/examples/reproject-map.html

There are some OL tickets opened up by elemoine that should make reprojection easier, but I don't have the numbers by hand right now.

Best regards,
Bart
