Constants

DEFAULT_PARAMS

{Object} Hashtable of default parameter key/value pairs

Properties

isBaseLayer

{Boolean} Default is true for WMS layer

encodeBBOX

{Boolean} Should the BBOX commas be encoded? The WMS spec says ‘no’, but some services want it that way. Default false.

Constructor

OpenLayers. Layer.WMS

Create a new WMS layer object

Example

var wms = new OpenLayers.Layer.WMS("NASA Global Mosaic",
                                   "http://wms.jpl.nasa.gov/wms.cgi",
                                   {layers: "modis,global_mosaic"});

options	{Ojbect} Hashtable of extra options to tag onto the layer

Functions

mergeNewParams

mergeNewParams:function( newParams )

Once params have been changed, we will need to re-init our tiles.

Parameters
