public class TLcdGXYPen
extends ALcdGXYPen
implements ILcdGXYPen, Serializable

ILcdGXYPen for painting and editing elementary shapes defined in a geodetic model reference or grid reference with very high performance. The given model coordinates are assumed to be latitude longitude coordinates or cartesian grid coordinates (the height is not used). Most of the methods are implemented in an approximate way for the sake of performance (e.g. lines will be straight lines). See TLcdGeodeticPen and TLcdGridPen for more accurate pen implementations.
