Method Detail

mapPosToWgs

public Point mapPosToWgs(MapPos pos)

Description copied from interface: Projection

Convert a point on pixel map to WGS84 coordinates (decimal coordinates * 1000000)

Specified by:

mapPosToWgs in interface GeoMap

Specified by:

mapPosToWgs in interface Projection

Parameters:

pos - pixel point on the map (on 256x256 pixels map of the world 0E 0N is located at map pixel 128x : 128y)

Returns:

point in internally used WGS84 format (decimal degrees * 1000000)

wgsToMapPos

public MapPos wgsToMapPos(Point wgs,
                          int zoom)

Description copied from interface: Projection

Convert WGS84 coordinates to pixel point on map

Specified by:

wgsToMapPos in interface GeoMap

Specified by:

wgsToMapPos in interface Projection

Parameters:

wgs - WGS84 coordinates (decimal coordinates * 1000000)

zoom - zoom level for the map

Returns:

pixel position on map for the coordinates

setWidthHeightRatio

public void setWidthHeightRatio(double ratio)

Set ratio between width and height. Use 1 for a "square world map" or 2 for a stretched map. Only values >= 1 are accepted

Parameters:

ratio - width/height ratio

getRatio

public double getRatio()
