Class ExtendedGeneralPath

    java.lang.Object
      org.apache.batik.ext.awt.geom.ExtendedGeneralPath

All Implemented Interfaces:
  java.lang.Cloneable, ExtendedShape, java.awt.Shape

public class ExtendedGeneralPath
extends java.lang.Object
implements ExtendedShape, java.lang.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 float precision.

Warning : An elliptical arc may be composed of several path segments. For futher details, see the SVG Appendix F.6

  The enclosed general path.

Constructor Detail

### ExtendedGeneralPath

    public ExtendedGeneralPath()

  Constructs a new `ExtendedGeneralPath`.

### ExtendedGeneralPath

    public ExtendedGeneralPath(int rule)

  Constructs a new `ExtendedGeneralPath` with the specified winding rule to control operations that require the interior of the path to be defined.

### ExtendedGeneralPath

    public ExtendedGeneralPath(int rule,
                               int initialCapacity)

  Constructs a new `ExtendedGeneralPath` object with the specified winding rule and the specified initial capacity to store path coordinates.

### ExtendedGeneralPath

    public ExtendedGeneralPath(java.awt.Shape s)

  Constructs a new `ExtendedGeneralPath` object from an arbitrary `Shape` object.

Method Detail

### 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:
    `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

### computeArc

                                                 double y0,
                                                 double rx,
                                                 double ry,

  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);
