[OpenLayers-Dev] setting tile size

[Bart van den Eijnden (OSGIS)]

Hi Duarte,

OpenLayers creates a buffer (default value of 2 rows/columns) of tiles
around the map image, you can influence this using:

When creating a layer, add a 'buffer' option, and set it to '1':

  Layer('WMS', 'http://url', {'map':'foo'}, {'buffer':1}); 

You can set the size of mapping using css:

        #map {
            width: 768px;
            height: 512px;
        }

which corresponds in my case to:
<div id="map">

Best regards,
Bart
