createPointOnLine

public static Point2D createPointOnLine(Point2D lineStart,
                                        Point2D lineEnd,
                                        Point2D trigger)

Calculates Perpendicular Point of the Trigger on the Line, which goes through lineStart and lineEnd. !Warning: Can't move the Point over the Line, yet.

Parameters:

lineStart - startPoint of the Line

lineEnd - endPoint of the Line

trigger - Point to which the Perpendicular Point will get calculated

Returns:

Perpendicular Point on the Line

createIntersectionPoint

public static Point2D.Double createIntersectionPoint(Line2D line1,
                                                     Line2D line2)

distanceToLine

public static double distanceToLine(Point2D lineStart,
                                    Point2D lineEnd,
                                    Point2D trigger)

Calculates the Distance between a specified Point and a specified Line, which goes through lineStart and lineEnd.

Parameters:

lineStart - startPoint of the Line

lineEnd - endPoint of the Line

trigger - Point, whose distance to the Line should get Calculated

Returns:

Distance between the Point and the Line

toSimpleGeometry
