Method Detail

fromLatLngToPixel

public Point fromLatLngToPixel(LatLng latLng,
                               int zoom)

Returns the pixel coordinates corresponding to the specified latitude-longitude coordinates at the specified zoom.

Specified by:

fromLatLngToPixel in interface Projection

fromPixelToLatLng

public LatLng fromPixelToLatLng(PointView pixel,
                                int zoom)

Returns the latitude-longitude coordinates corresponding to the specified pixel coordinates at the specified zoom. This method should always return a legal value, even if the pixel coordinates fall outside the map. In such a case, the projection may, for example, choose to return the closest legal location or wrap around.

fromPixelToLatLng in interface Projection

getZoomMagnification

public double getZoomMagnification(int startZoom,
                                   int endZoom)

Returns the magnification coefficient between the two specified zooms, i.e. how much the map is magnified when the zoom is changed from startZoom to endZoom. This would normally be a value larger than 1 if endZoom is larger than startZoom and vice versa.

Specified by:

getZoomMagnification in interface Projection

getWrapSize

public SizeView getWrapSize(int zoom)

Returns the number of pixels after which the map wraps around the earth on each axis at the specified zoom. A value of 0 indicates that the map does not repeat itself.
