Methods

getTileSize

▸ getTileSize(): number

Returns

number

lonLatToMeters

▸ lonLatToMeters(lonlat, meters): DMapPoint

Converts the given (lon, lat) point in WGS84 to (x, y) in EPSG:900913. The origin of the converted point (x, y) is at the middle-left corner. The meters can be the same instance that is passed in as the lonlat.

Parameters

Name	Type	Description
lonlat	DMapPoint	(lon, lat) point
meters	DMapPoint	(x, y) point in meters converted from the given lonlat.

Returns

DMapPoint

(x, y) point in meters
