OpenLayers. Control. Graticule

The Graticule displays a grid of latitude/longitude lines reprojected on the map.

Summary

OpenLayers. Control. Graticule	The Graticule displays a grid of latitude/longitude lines reprojected on the map.
Properties
intervals	{Array(Float)} A list of possible graticule widths in degrees.
displayInLayerSwitcher	{Boolean} Allows the Graticule control to be switched on and off.
visible	{Boolean} should the graticule be initially visible (default=true)
numPoints	{Integer} The number of points to use in each graticule line.
targetSize	{Integer} The maximum size of the grid in pixels on the map
layerName	{String} the name to be displayed in the layer switcher
labelled	{Boolean} Should the graticule lines be labelled?.
labelFormat	{String} the format of the labels, default = ‘dm’.
lineSymbolizer	{symbolizer} the symbolizer used to render lines
labelSymbolizer	{symbolizer} the symbolizer used to render labels
gratLayer	{OpenLayers.Layer.Vector} vector layer used to draw the graticule on
Constructor
OpenLayers. Control. Graticule	Create a new graticule control to display a grid of latitude longitude lines.
Functions
draw	initializes the graticule layer and does the initial update
update	calculates the grid to be displayed and actually draws it

{Array(Float)} A list of possible graticule widths in degrees.

{Boolean} Allows the Graticule control to be switched on and off. defaults to true.

{Boolean} should the graticule be initially visible (default=true)

{Integer} The number of points to use in each graticule line. Higher numbers result in a smoother curve for projected maps

{Integer} The maximum size of the grid in pixels on the map

{String} the name to be displayed in the layer switcher

{Boolean} Should the graticule lines be labelled?. default=true

{String} the format of the labels, default = ‘dm’. See <OpenLayers.Util.getFormattedLonLat> for other options.

{symbolizer} the symbolizer used to render lines

{symbolizer} the symbolizer used to render labels

{OpenLayers.Layer.Vector} vector layer used to draw the graticule on

Create a new graticule control to display a grid of latitude longitude lines.

options

{Object} An optional object whose properties will be used to extend the control.
