Class GridLiner

java.lang.Object
  uk.ac.starlink.ttools.plot2.geom.GridLiner

public class GridLiner
extends Object

This class is used to lines and text to draw coordinate grid grid overlays. in a Graphics context.

This is basically the skyview.data.Gridder class from Tom McGlynn's Skyview package. Some very minor modifications have been made to adapt it to the TTOOLS plotting requirements.
