Constants

MIN_ZOOM_LEVEL

{Integer} 0

MAX_ZOOM_LEVEL

{Integer} 17

RESOLUTIONS

{Array(Float)} Hardcode these resolutions so that they are more closely tied with the standard wms projection

Properties

type

{YahooMapType}

wrapDateLine

{Boolean} Allow user to pan forever east/west. Default is true. Setting this to false only restricts panning if sphericalMercator is true.

sphericalMercator

{Boolean} Should the map act as a mercator-projected map? This will cause all interactions with the map to be in the actual map projection, which allows support for vector drawing, overlaying other maps, etc.

Constructor

OpenLayers. Layer. Yahoo

Parameters

name	{String}
options	{Object}

Functions

setMap

setMap: function( map )
