Examples of java.awt.geom.Line2D.ptLineDistSq()

java.awt.geom.Line2D.ptLineDistSq()
Returns the square of the distance from a point to a line. The distance measured is the distance between the specified point and the closest point on the infinitely-extended line defined by the specified coordinates. If the specified point intersects the line, this method returns 0.0. @param x1 the X coordinate of the start point of the specified line @param y1 the Y coordinate of the start point of the specified line @param x2 the X coordinate of the end point of the specified line @param y2 the Y coordinate of the end point of the specified line @param px the X coordinate of the specified point beingmeasured against the specified line @param py the Y coordinate of the specified point beingmeasured against the specified line @return a double value that is the square of the distance from thespecified point to the specified line. @see #ptSegDistSq(double,double,double,double,double,double) @since 1.2
