Note
The graphic rendering of a group object is optimized for performance using an offscreen buffered image technique that minimizes the complex polygon computations by pre-rendering the graphic object in memory. The extra memory required is proportional to the size and number of visible objects in the Network view. To disable the offscreen optimizations for the group representation you should: 1. Set the ilog.tgo.polygon.offscreenCache system property to false at initialization time.2. Use the IltSettings.SetValue("OffscreenCache.Polygon", Boolean.FALSE); API call Please refer to your Java Runtime documentation on how to declare system properties for Java applications and applets.

This section explains how to customize each attribute/decoration of the group representation:
