Hi, I need to compute the "signed distance" of a point P from a polygon Q, i.e., the distance of P from the polyline including Q with a "+" sign if the point is inside the polygon and a "-" sign if it is outside.
I see "distancePointPolygon" in the geometry package computes the distance but always returns a positive number. Is there already a function to do what I need? If not, any idea where I can look-up the algorithm to modify "distancePointPolygon" according to my needs? Thanks, c. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
