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

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