[mapserver-users] Re: [OpenLayers-Users] Doubt with layers

[Rafael chacón]

Hi, thanks for the answer.. I didn't have the layers in png or gif.. I did
that but  the overlays is still not working.. Look how is the declaration
now .. I kind of stuck:

Mapserver:


MAP
  size 800  600
  imagetype 'png'
  TRANSPARENT ON
  imagecolor 0 0 255
  extent -180 -90 180 90
  SYMBOLSET "symbols"
  PROJECTION
    "init=epsg:4269"
  END

  WEB
    IMAGEPATH "/var/www/apache2-default/gis_tests/tmp/"
    IMAGEURL "/apache2-default/gis_tests/tmp/"
    TEMPLATE "empty.html"
    LOG "log"
    metadata
      wms_title "us_states"
      wms_srs "EPSG:4269"
    end
  end

  outputformat
    name "png"
    driver "GD/PNG"
    imagemode "rgba"
    extension "png"
    mimetype "image/png"
    imagemode RGBA
  end
---------

Openlayers:


             layer = new OpenLayers.Layer.MapServer( "Estados unidos",
                      "
http://192.168.1.100/cgi-bin/mapserv?map=us_states.map",
                      {layers: 'us_states', 'format':'image/png'});
             roads = new OpenLayers.Layer.MapServer( "Roads",
                      "
http://192.168.1.100/cgi-bin/mapserv?map=us_states.map",
                      {layers: 'us_roads',transparent: 'true',
'format':'image/png'}, {isBaseLayer:false});
             gps = new OpenLayers.Layer.MapServer( "GPS",
                      "
http://192.168.1.100/cgi-bin/mapserv?map=us_states.map",
                      {layers: 'gps_points', transparent: 'true',
'format':'image/png' }, {isBaseLayer:false});

            roads.setVisibility(false);
            gps.setVisibility(false);



Thaks for your help :)
