This example demonstrates feature editing with snapping to a regular
|
|
grid. The map is configured with a <code>OpenLayers.Layer.PointGrid</code>
|
|
layer and a <code>OpenLayers.Control.Snapping</code> agent. For the
|
|
best performance, the point grid layer should not made visible.
|
|
Snapping still works with layers that are not visible.
