Method Details

calculateMapTile

public static MapTile calculateMapTile(MapPos mapPos,
 int zoom,
 Projection proj)

Calculates the map tile corresponding to specified point and zoom level.

Parameters:

mapPos - Coordinates for the point.

zoom - Zoom level for the tile.

proj - The projection to use for tile and point.

Returns:

The corresponding map tile.

calculateClippedMapTile

public static MapTile calculateClippedMapTile(MapPos mapPos,
 int zoom,
 Projection proj)

Calculates the map tile corresponding to specified point and zoom level. If the resulting tile is outside the valid range, it will be clipped.

Parameters:

mapPos - Coordinates for the point.

zoom - Zoom level for the tile.

proj - The projection to use for tile and point.

Returns:

The corresponding map tile.

calculateMapTileOrigin

public static MapPos calculateMapTileOrigin(MapTile mapTile,
 Projection proj)

Calculates origin coordinates for the given map tile.

Parameters:

mapTile - The map tile to use.

proj - The projection to use for origin.

Returns:

The corresponding tile origin.

calculateMapTileBounds

public static MapBounds calculateMapTileBounds(MapTile mapTile,
 Projection proj)

Calculates bounds for the given map tile.

Parameters:

mapTile - The map tile to use.

proj - The projection to use for bounds.

Returns:

The corresponding tile bounds.
