Method Detail

getIntersection

public static java.awt.geom.Point2D getIntersection(java.awt.geom.Line2D lineA,
                                    java.awt.geom.Line2D lineB)

Get intersection point between 2 lines.

Returns:

the intersection point between 2 lines, it can return null if the 2 lines are //

getIntersection

public static java.awt.geom.Point2D getIntersection(java.awt.geom.Line2D lineA,
                                    java.awt.geom.Line2D lineB,
                                    boolean limitToSegmentA,
                                    boolean limitToSegmentB)

Get intersection point between 2 lines.

Parameters:

lineA - first line

lineB - second line

limitToSegmentA - Limit intersection to segment lineA, if intersection point is outside lineA then null is returned

limitToSegmentB - Limit intersection to segment lineB, if intersection point is outside lineB then null is returned

getRotation
