[OpenLayers-Dev] snapping

[Jachym Cepicky]

Hi,

it looks great, but will there be any "beforeSnap" method, which could
be customised by the user?

/**
 * Method: beforeSnap
 * Customizing the resulting coordinates
 *
 * Parameters:
 * point - {<OpenLayers.Point>}
 * snapped - {Boolean} the point was already snapped to some object
 *
 * Returns:
 * {Point} - resulting point
 */
beforeSnap: function(point,snapped) {
        // custom snapping, e.g. server-side correction
        // ...
        return point;
},

Thanks

Jachym
