Modeling Class Summary

The classes used for modeling are listed in the table below:

 

Class

Description

IMDrawable An abstract base class, from which the 2D graphics classes descend, that allows a graphic object to draw itself.
IMGraphic An abstract base class that provides protocols for constructing and deleting a 2D graphic, obtaining attribute information, transforming the graphic, and finding the bounds of the graphic.
ILine Wrapper for the geometry class IGLine2D.
IPolyline Wrapper for the geometry class IGPolyline2D.
ICurve Wrapper for the geometry class IGCurve2D.
IEllipse Wrapper for the geometry class IGEllipse2D.
ILoop Wrapper for the geometry class IGLoop2D.
IPolygon Wrapper for the geometry class IGPolygon2D.
IArea Wrapper for the geometry class IGArea2D.
IImage Wrapper for the geometry class IGImage2D.
IGraphicHierarchy An abstract base class that defines a hierarchy protocol for grouped graphics.
IGraphicIterator An abstract base class that allows interation of a graphics hierarchy.
IGraphicGroup A concrete class, derived from IGraphicHierarchy, that implements a group of graphics as a tree structure. This class for combines 2D graphics into a unit that is treated as a whole.
IGraphicGroupIterator A class that provides functions to traverse and manage a hierarchical tree of graphic objects.
