Properties

projection

{String} Map projection code. Default is “EPSG:900913”.

// Get map projection for this layer.
var projection = tileLayer.projection;
// Set map projection for this layer. Or projection can be passed in as options parameter when the layer instance is created.
tileLayer.projection = L.CRS.EPSG900913.code;

region

{String} map data region code

dataset

style

{String} map style

imgsrc

{String} satellite provider may take effect only if style is set to satellite. Default is null. Available options are sat1, sat2, sat3, sat4, sat5, sat6.

attribution

{String} Leaflet.TileLayer attribution setting

attrPosition

{String} Leaflet.TileLayer attrPosition setting. Specify “topleft” for top left of map, “topright” for top right, “bottomleft” for bottom left or “bottomright” for bottomright. Defaults to “bottomright”.

attrUseHyperlink

{Boolean} Leaflet.TileLayer attrUseHyperlink setting. Whether or not to show the hyperlink to alk maps in the attribution. Defaults to true.

minZoom

{Number} Leaflet.TileLayer minimum zoom setting. Will be overridden by map’s equivalent option.

maxZoom

{Number} Leaflet.TileLayer maximum zoom setting. Will be overridden by map’s equivalent option.

isBaseLayer

{Boolean} Flag indicating if the Tile layer instance is the base layer.

tileSize

{Number} Width of the tile.

drawergroups

{String} Comma separated string values such as “cities,labels”. If not supplied, ALKMaps.CONTENT.DEFAULT will be used. DEFAULT values are “cities,labels,roads,borders,areas”.

Constructor

L.ALKMaps.Layer.Tile

Initializes a new Tile layer object

Parameters

options

{Object} Tile Layer Options

Functions

setStyle

setStyle: function ( styleName )

sets/changes style of the map

Parameters

styleName

{String} map style (“default”, “classic”, “night” ,...)

setRegion

setRegion: function ( regionCode )

sets/changes region of the map

Parameters

regionCode

{String} the code for the map region (“NA”, “AS”, “EU”, ...)
