Method Detail

GetIntersections

public static java.util.ArrayList<java.awt.geom.Point2D> GetIntersections(java.awt.geom.GeneralPath path,
                                                                          java.awt.geom.Line2D line)

Calculates intersection points of a line segment and GeneralPath object. GeneralPath object must contain only cubic bezier curves, other geometric shapes are not supportet yet

Returns:

List of intersection points of path and line

GetIntersections

public static java.util.ArrayList<java.awt.geom.Point2D> GetIntersections(java.awt.geom.CubicCurve2D curve,
                                                                          java.awt.geom.Line2D line)

Calculates intersection points of a line segment and cubic Bezier curve

Returns:

List of intersection points
