Class ReferencePoint

java.lang.Object
  |
  +--util.ReferencePoint

public class ReferencePoint

extends java.lang.Object

This class represents a reference point on a map image. A reference point is where pixel x equals a longitude value, and pixel y equals a latitude value. Thus every ReferencePoint object must contain an x pixel, a y pixel, and the corresponding longitude and latitude value. This is class is need ed so that we can take a pixel point on a map and determine its latitude/longitude in the real world. And thus we can send real latitude longitude values to the ipaq gps receiver program.
