If it could help you I describe how I modified the zoom2extent function in
the 'pm.map.js' for my project.
As zoom2extent for multiple selection sometimes doesn't zoom to all
selected, I created 2 zoom2extent functions as follow.
The first one decrease zoom extent by a factor as you can see. In this way
all selected features are included in the view (extent).
The second one is the standard zoom2extent used for a single feature zoomTo.
You have to modified 'pm.queryconfig.js' file where the function is called
(zoom2extent --> zoom2extent2 line 66).
zoom2extent: function(layer, idx, extStr, zoomfull) {
var ext = extStr.split(",");
var minx = (ext[0]*0.9995);
var miny = (ext[1]*0.9995);
var maxx = (ext[2]*1.0005);
var maxy = (ext[3]*1.0005);
map.zoomToExtent( new OpenLayers.Bounds(minx, miny, maxx,
maxy), true );
},
zoom2extent2: function(layer, idx, extStr, zoomfull) {
var ext = extStr.split(",");
var minx = (ext[0]);
var miny = (ext[1]);
var maxx = (ext[2]);
var maxy = (ext[3]);
map.zoomToExtent( new OpenLayers.Bounds(minx, miny, maxx,
maxy), true );
},
