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}

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
