Class IlvOutlinedPathDecoration

java.lang.Object

ilog.views.maps.graphic.IlvClippedPathDecoration

ilog.views.maps.graphic.IlvOutlinedPathDecoration

All Implemented Interfaces:

IlvPersistentObject, IlvPathDecoration, Serializable

public class IlvOutlinedPathDecoration
extends IlvClippedPathDecoration
implements IlvPersistentObject

A path decoration that uses a BasicStroke as base stroke. The stroke is defined using the same parameters as java.awt.BasicStroke. This stroke can be either filled, stroked, or both. A zoomable IlvStrokedPathDecoration behaves like a java.awt.BasicStroke that is clipped to the visible part of the shape it strokes.
A non-zoomable IlvOutlinedPathDecoration has its width and dash always at a specified pixel size.

Since:

JViews 5.0
