public class OMPoint
extends OMGraphicAdapter
implements OMGraphic, java.io.Serializable

A OMPoint is used to mark a specific point. You can set this point as a lat/lon position, a screen X/Y position, or a lat/lon position with a screen X/Y offset. The position can be marked with a rectangle or circle with an adjusted radius. The radius is the pixel distance from the center of the location to each edge of the marking rectangle or circle.
