GPolygon.prototype.Contains = function(point) {
var j=0;
var oddNodes = false;
var x = point.lng();
var y = point.lat();
for (var i=0; i < this.getVertexCount(); i++) {
j++;
if (j == this.getVertexCount()) {j = 0;}
if (((this.getVertex(i).lat() < y) && (this.getVertex(j).lat
() >= y))
|| ((this.getVertex(j).lat() < y) && (this.getVertex(i).lat
() >= y))) {
if ( this.getVertex(i).lng() + (y - this.getVertex(i).lat
())
/ (this.getVertex(j).lat()-this.getVertex(i).lat())
* (this.getVertex(j).lng() - this.getVertex(i).lng())<x )

oddNodes = !oddNodes
}
}
}
return oddNodes;
}
This is where I am confused. looking here: http://econym.org.uk/gmap/inside.htm
It points out that the following is no longer needed. And I have
looked to to avail what version of the map I am using.
If I could get this cleared up I think it would solve the majority of
my problems. Because I use the above function on my map currently
without a problem.
