public class ExtendedGeneralPath extends Object implements ExtendedShape, Cloneable
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
Field Summary | |

Constructor Summary | |
---|---|
ExtendedGeneralPath()
Constructs a new ExtendedGeneralPath . | |
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(int rule, int initialCapacity)
Constructs a new ExtendedGeneralPath object with
the specified winding rule and the specified initial capacity
to store path coordinates. | |
ExtendedGeneralPath(Shape s)
Constructs a new ExtendedGeneralPath object from
an arbitrary Shape object. |

void | arcTo(float rx, float ry, float angle, boolean largeArcFlag, boolean sweepFlag, float x, float 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.

Checks if previous command was a moveto command,
skipping a close command (if present). |

.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.
