Class Ellipse

java.lang.Object
org.eclipse.gef.geometry.planar.Ellipse
All Implemented Interfaces:
Serializable, Cloneable, IGeometry, IRotatable<PolyBezier>, IScalable<Ellipse>, IShape, ITranslatable<Ellipse>
public class Ellipse extends Object implements IShape
Represents the geometric shape of an ellipse. Note that while all manipulations (e.g. within shrink, expand) within this class are based on double precision, all comparisons (e.g. within contains, intersects, equals, etc.) are based on a limited precision (with an accuracy defined within PrecisionUtils) to compensate for rounding effects.
