[OpenLayers-Users] boundaries of lineString

[Rupesh M G]

        Thank you for the reply. But I think it is not correct.

For example, if I draw the linestring with 4 points, I'm able to see a 
polygon with 8 vertices.

But if I print the components.length of the linestring, it just says 4.

I tried it with the example in the url 
http://openlayers.org/dev/examples/vector-features.html


Regards,
Rupesh

It should be quite easy because geometry like lineString and Polygon
are composite geometries.
For example, a OpenLayers.LineString has a 'components' property which
is an array of OpenLayers.Points.
That way, you can get all the vertices using a loop like following :

for(var i=0; i <= thelinestring.components.length; i++) {
    // do something with thelinestring.components[i] which is an OL point
}

Pierre
