方法详细资料

getMapSize

public Dimension getMapSize(int zoom)

从类复制的说明: TileFactory

Returns a Dimension containing the width and height of the map, in tiles at the current zoom level. So a Dimension that returns 10x20 would be 10 tiles wide and 20 tiles tall. These values can be multipled by getTileSize() to determine the pixel width/height for the map at the given zoom level

覆盖:

getMapSize 在类中 TileFactory

参数:

zoom - the current zoom level

返回:

the size of the world bitmap in tiles

geoToPixel

public Point2D geoToPixel(GeoPosition c,
                          int zoom)

从类复制的说明: TileFactory

Convert a GeoPosition to a pixel position in the world bitmap a the specified zoom level.

覆盖:

geoToPixel 在类中 TileFactory

参数:

c - a GeoPosition

zoom - the zoom level to extract the pixel coordinate for

返回:

the pixel point

pixelToGeo

public GeoPosition pixelToGeo(Point2D pix,
                              int zoom)

从类复制的说明: TileFactory

Convert a pixel in the world bitmap at the specified zoom level into a GeoPosition

覆盖:

pixelToGeo 在类中 TileFactory

参数:

pix - a Point2D representing a pixel in the world bitmap

zoom - the zoom level of the world bitmap

返回:

the converted GeoPosition
