Interface ExtendedPathIterator

  • public interface ExtendedPathIterator
    The ExtendedPathIterator class represents a geometric path constructed from straight lines, quadratic and cubic (Bezier) curves and elliptical arcs. This interface is identical to that of PathIterator except it can return SEG_ARCTO from currentSegment, also the array of values passed to currentSegment must be of length 7 or an error will be thrown. This does not extend PathIterator as it would break the interface contract for that class.

      • SEG_LINETO

        Constant Field Values

      • SEG_QUADTO

        static final int SEG_QUADTO
        The segment type constant for the pair of points that specify a quadratic parametric curve to be drawn from the most recently specified point. The curve is interpolated by solving the parametric control equation in the range (t=[0..1]) using the most recently specified (current) point (CP), the first control point (P1), and the final interpolated control point (P2).

        Constant Field Values

      • SEG_CUBICTO

        static final int SEG_CUBICTO
        The segment type constant for the set of 3 points that specify a cubic parametric curve to be drawn from the most recently specified point. The curve is interpolated by solving the parametric control equation in the range (t=[0..1]) using the most recently specified (current) point (CP), the first control point (P1), the second control point (P2), and the final interpolated control point (P3).

        Constant Field Values

      • SEG_ARCTO

        static final int SEG_ARCTO
        The segment type constant for an elliptical arc. This consists of Seven values [rx, ry, angle, largeArcFlag, sweepFlag, x, y]. rx, ry are the radious of the ellipse. angle is angle of the x axis of the ellipse. largeArcFlag is zero if the smaller of the two arcs are to be used. sweepFlag is zero if the 'left' branch is taken one otherwise. x and y are the destination for the ellipse.

        Constant Field Values

      • WIND_EVEN_ODD

        static final int WIND_EVEN_ODD
        The winding rule constant for specifying an even-odd rule for determining the interior of a path. The even-odd rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments an odd number of times.
        See Also:
        Constant Field Values

      • WIND_NON_ZERO

        static final int WIND_NON_ZERO
        The winding rule constant for specifying a non-zero rule for determining the interior of a path. The non-zero rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments a different number of times in the counter-clockwise direction than the clockwise direction.
