Composite Graphic Objects

Composite graphic object classes and subclasses provide member functions that allow you to reference instances of IlvGraphic subtyped objects. You can use these references for:

• Controlling polygon fill. See Filling Polygons: IlvGraphicPath.

• Grouping objects. See Grouping Objects: IlvGraphicSet .

• Modifying properties of one object without duplicating or modifying the object itself. See Referencing Objects: IlvGraphicHandle .

For example, in an electronic schema displaying a thousand transistors, you would consume much less memory by creating one transistor image and a thousand handle objects to reference it than by creating a thousand separate images.
