All Implemented Interfaces:

Shape, Cloneable
```
public class ExtendedGeneralPath
extends Object
implements Shape, Cloneable
```
The ExtendedGeneralPath class represents a geometric path constructed from straight lines, quadratic and cubic (Bezier) curves and elliptical arc. This class delegates lines and curves to an enclosed GeneralPath. Elliptical arc is implemented using an Arc2D in double precision.
Warning : An elliptical arc may be composed of several path segments. For futher details, see the SVG Appendix F.6

  - arcTo
```
public void arcTo(double rx,
                  double ry,
                  double angle,
                  boolean largeArcFlag,
                  boolean sweepFlag,
                  double x,
                  double y)
```
    Adds an elliptical arc, defined by two radii, an angle from the x-axis, a flag to choose the large arc or not, a flag to indicate if we increase or decrease the angles and the final point of the arc.
    
    Parameters:
    
    rx - the x radius of the ellipse
    
    ry - the y radius of the ellipse
    
    angle - the angle from the x-axis of the current coordinate system to the x-axis of the ellipse in degrees.
    
    largeArcFlag - the large arc flag. If true the arc spanning less than or equal to 180 degrees is chosen, otherwise the arc spanning greater than 180 degrees is chosen
    
    sweepFlag - the sweep flag. If true the line joining center to arc sweeps through decreasing angles otherwise it sweeps through increasing angles
    
    x - the absolute x coordinate of the final point of the arc.
    
    y - the absolute y coordinate of the final point of the arc.
  - computeArc
```
public static Arc2D computeArc(double x0,
                               double y0,
                               double rx,
                               double ry,
                               double angle,
                               boolean largeArcFlag,
                               boolean sweepFlag,
                               double x,
                               double y)
```
    This constructs an unrotated Arc2D from the SVG specification of an Elliptical arc. To get the final arc you need to apply a rotation transform such as: AffineTransform.getRotateInstance (angle, arc.getX()+arc.getWidth()/2, arc.getY()+arc.getHeight()/2);
