## com.bbn.openmap.omGraphics
Class OMRect

    java.lang.Object
      com.bbn.openmap.omGraphics.geom.BasicGeometry
          com.bbn.openmap.omGraphics.OMGraphic
              com.bbn.openmap.omGraphics.OMRect

All Implemented Interfaces:
  java.lang.Cloneable, OMGeometry, OMGraphicConstants, java.io.Serializable

Direct Known Subclasses:
  Waypoint.Graphic

public class OMRect
extends OMGraphic
implements java.io.Serializable

Graphic type that lets you draw four-sided polygons that have corners that share coordinates or window points.

### NOTE:

See the RESTRICTIONS on Lat/Lon polygons/polylines which apply to rectangles as well. Not following the guidelines listed may result in ambiguous/undefined shapes! Similar assumptions apply to the other vector graphics that we define: circles, ellipses, polys, lines.

These assumptions are virtually the same as those on the more generic OMPoly graphic type.
