[OpenLayers-Users] boundaries of lineString

[Pierre GIRAUD]

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
}

Regards,
Pierre
