Constructor Detail

UnstreamedDoubleSizedTilesMap

public UnstreamedDoubleSizedTilesMap(GeoMap resizedMap)

Resizes ("zooms in") all map images for the map, exactly 2 times

Parameters:

resizedMap - Map which will be used as resized map, could be any map service of library

UnstreamedDoubleSizedTilesMap

public UnstreamedDoubleSizedTilesMap(GeoMap resizedMap,
                                     boolean resizeOnlyLastLevel)
