[OpenLayers-Users] Signatures cutting by tiles

[Krinke, Claus]

Hello List, 

The image http://www.lrop.niedersachsen.de/FIS-RO/tile_signature.jpg shows
the problem. Signatures are cut off by the tiles. The WMS service is
supplied by the UMN-Mapserver. Is there a solution for the problem?


My layer definition in the html ist:

layers[0] = newWMSlayer("Oberzentren",
"http://10.4.103.89/cgi-bin/mapserv.xml?map=D:/ms4w/Apache/htdocs/gis/ZO.map
", {layers: 'Oberzentren', request:
'getmap',transparent:true,format:'image/png'}, {tileSize: new
OpenLayers.Size(512,512), buffer: 1}, true, false, 1);

layers[1] = newWMSlayer("Mittelzentren",
"http://10.4.103.89/cgi-bin/mapserv.xml?map=D:/ms4w/Apache/htdocs/gis/ZO.map
", {layers: 'Mittelzentren', request:
'getmap',transparent:true,format:'image/png'}, {tileSize: new
OpenLayers.Size(512,512), buffer: 1}, true, false, 1);

And the layer definition in the .map file is:
