Very very thanks. It worked fine. but one strange point: Why they don't easily compute this maxRsolution in their lib using with of map element (instead of supposing all map elements to be in 256*256 size)? Anyway, your helpful point is totally appreciated.

If you request MapServer via OpenLayers.WMS, then the mapoptions are the point. By default is the maxResolution = 1.40625 and the other resolutions are maxResolution/2^zoom. (1.40625 , 0.703125, 0.3515625, ...) map.zoomToMaxExtent() uses the resolution = 0.703125, because that is the best resolution to display maxExtent (-180,-90,180,90). For the next resolution the map would not display in whole. You can set maxResolution=0.45 in the mapoptions. Then the layer should fill the whole map.

In fact, in first step i created map without any extra argument and faced that problem and after that i added some arguments to maybe solve the problem. Any idea now? ________________________________ From: Stephen Woodbridge <[email protected]> To: [email protected] Sent: Sat, June 4, 2011 10:04:29 PM Subject: Re: [mapserver-users] Problem in extent using openlayers with Mapserver try just using: map = new OpenLayers.Map( 'map' ); -Steve On 6/4/2011 1:21 PM, Saka Royban wrote: > Hi all. > I've really got stuck in this problem and need some help as i'm a newbie > using openlayers with mapserver. > In mapfile i've set output to be: > EXTENT -180 -90 180 90 # Geographic > SIZE 800 400 > IMAGECOLOR 128 128 255 > > when i request mapserver through URL, i recieve a complete 800*400 > image, but when i use openlayers i get a 800*400 image which original > map fills 512*256 of the center and other pixels are filled with IMAGECOLOR. > this is my code: > map = new OpenLayers.Map( 'map',{'tileSize': new > OpenLayers.Size(400,400)} ); > layer = new OpenLayers.Layer.MapServer( "World Map", > "http://localhost/cgi-bin/mapserv.exe";, {map: > '/ms4w/apps/ms101/htdocs/ms101.map',layers: 'world_poly', height: 400, > width: 800}, {singleTile: true} ); > > map.addLayer(layer); > map.zoomToMaxExtent(); > > I asked this question in openlayers mailing list with no success.
