ptSegDistSq

public static double ptSegDistSq(double x1,
 double y1,
 double x2,
 double y2,
 double px,
 double py)

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.

Parameters:

x1 - the X coordinate of the start point of the specified line segment

y1 - the Y coordinate of the start point of the specified line segment

x2 - the X coordinate of the end point of the specified line segment

y2 - the Y coordinate of the end point of the specified line segment

px - the X coordinate of the specified point being measured against the specified line segment

py - the Y coordinate of the specified point being measured against the specified line segment

Returns:

a double value that is the square of the distance from the specified point to the specified line segment.

Since:

1.2

intersect

drawU

public void drawU(UGraphic ug)

Specified by:
