Summary

OpenLayers. Layer. MapGuide	Instances of OpenLayers.Layer.MapGuide are used to display data from a MapGuide OS instance.
Properties
isBaseLayer	{Boolean} Treat this layer as a base layer.
singleTile	{Boolean} use tile server or request single tile image.
Constants
TILE_PARAMS	{Object} Hashtable of default parameter key/value pairs for tiled layer
SINGLE_TILE_PARAMS	{Object} Hashtable of default parameter key/value pairs for untiled layer
Constructor
OpenLayers. Layer. MapGuide	Create a new Mapguide layer, either tiled or untiled.

Properties

isBaseLayer

{Boolean} Treat this layer as a base layer. Default is true.

singleTile

{Boolean} use tile server or request single tile image. Note that using singleTile and isBaseLayer false is not recommend: it uses synchronous XMLHttpRequests to load tiles, and this will lock up users browsers during requests.

Constants

TILE_PARAMS

{Object} Hashtable of default parameter key/value pairs for tiled layer

SINGLE_TILE_PARAMS

{Object} Hashtable of default parameter key/value pairs for untiled layer

Constructor

OpenLayers. Layer. MapGuide

Create a new Mapguide layer, either tiled or untiled.

For tiled layers, the ‘groupName’ and ‘mapDefnition’ options must be specified as options.

For untiled layers, specify either combination of ‘mapName’ and ‘session’, or ‘mapDefinition’ and ‘locale’.

Parameters

name	{String} Name of the layer displayed in the interface
url	{String} Location of the MapGuide mapagent executable (e.g. http://localhost:8008- /mapguide- /mapagent- /mapagent.fcgi)
params	{Object} hashtable of additional parameters to use. Some parameters may require additional code on the serer. The ones that you may want to use are:

mapDefinition - {String} The MapGuide resource definition (e.g. Library://Samples/Gmap/Maps/gmapTiled.MapDefinition)
locale - Locale setting (for untiled overlays layers only)
mapName - {String} Name of the map as stored in the MapGuide session. (for untiled layers with a session parameter only)
session - { String} MapGuide session ID (for untiled overlays layers only)
basemaplayergroupname - {String} GroupName for tiled MapGuide layers only
format - Image format to be returned (for untiled overlay layers only)
showLayers - {String} A comma separated list of GUID’s for the layers to display eg: ‘cvc-xcv34,453-345-345sdf’.
hideLayers - {String} A comma separated list of GUID’s for the layers to hide eg: ‘cvc-xcv34,453-345-345sdf’.
showGroups - {String} A comma separated list of GUID’s for the groups to display eg: ‘cvc-xcv34,453-345-345sdf’.
hideGroups - {String} A comma separated list of GUID’s for the groups to hide eg: ‘cvc-xcv34,453-345-345sdf’
selectionXml - {String} A selection xml string Some server plumbing is required to read such a value.

options

{Ojbect} Hashtable of extra options to tag onto the layer; will vary depending if tiled or untiled maps are being requested
