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. |
