open class Ellipse2D : Form

Defines an SVS 2D-Ellipse

FloatAttribute

class FloatAttribute : Attribute

A class that represents a float attribute (see Attribute class).

Form

abstract class Form : CPPAdapter

Defines the abstraction layer of all geometric (and none geometric) forms handled by the SVS format.
