Detailed Description

The abstract base class of all 2D graphics primitives.

Graphics primitives are simple (atomic) geometrical objects which can be used as building blocks for larger and more complex drawings (e.g. the 2D depiction of a molecular structure). The actual type (e.g. point, line, polygon, ...) and look (e.g. color, font, ...) of an graphics primitive is defined by subclasses of GraphicsPrimitive2D. Subclasses have to implement the render() method that visualizes the primitive by means of a Renderer2D implementation instance.
