Class TileZXY

java.lang.Object

org.openstreetmap.josm.data.osm.visitor.paint.TileZXY

All Implemented Interfaces:

ILatLon

public final class TileZXY
extends java.lang.Object
implements ILatLon

A record used for storing tile information for painting. The origin is upper-left, not lower-left (so more like Google tile coordinates than TMS tile coordinates).
