Hello,
I would like to transform coordinates of every point of a polygon feature
drawned by the user using the polygon measure tool. In a function a get the
geometry:
for (var lyr=0; lyr < map.layers.length; ++lyr){
var layer = map.layers[lyr];
if(layer.CLASS_NAME=="OpenLayers.Layer.Vector"){
alert('toString
'+layer.features[0].geometry.toString());
}
}
The alert shows a message like this:
POLYGON((295568,4706540,469875,4690960,443475,4589500,307175,4592100,295568,4706540))
for a polygon drawned by the client user width 4 corners.
How can I get every pair of coordinates to send to getViewPortPxFromLonLat? so
that I need pixels coordinates of every point.
Thanks in advance
