| ExtendedGeneralPath | | public class ExtendedGeneralPath implements ExtendedShape,Cloneable(Code) | | 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

| arcTo | | public synchronized void arcTo(float rx, float ry, float angle, boolean largeArcFlag, boolean sweepFlag, float x, float y)(Code) | | 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
Parameters:
ry - the y radius of the ellipse
Parameters:
angle - the angle from the x-axis of the currentcoordinate system to the x-axis of the ellipse in degrees.
Parameters:
largeArcFlag - the large arc flag. If true the arcspanning less than or equal to 180 degrees is chosen, otherwisethe arc spanning greater than 180 degrees is chosen
Parameters:
sweepFlag - the sweep flag. If true the line joiningcenter to arc sweeps through decreasing angles otherwise itsweeps through increasing angles
