[pmapper-users] Pmapper5: zoom to selected features

[gioza <al...@al...>]

Hi,
in pmapper5 using the search box or select by shape, have any of you
realised that the function "zoom to selected features" doesn't display the
complete extent of selected items?

I figured out with a change to pm.map.js:

add to line 162->166 the map.zoomOut() control in this way:

FROM
  zoom2extent: function(layer, idx, extStr, zoomfull) {
    	var ext = extStr.split(",");
		map.zoomToExtent( new OpenLayers.Bounds(ext[0], ext[1], ext[2], ext[3]),
true );
		    },


TO
  zoom2extent: function(layer, idx, extStr, zoomfull) {
    	var ext = extStr.split(",");
		map.zoomToExtent( new OpenLayers.Bounds(ext[0], ext[1], ext[2], ext[3]),
true );
		map.zoomOut();
    },

As you select a features by "search tools" the zoomToextent will zoom out so
that all the features you selected with the query are completely visible

for better performance add PM.Map.clearHighlight in pm.query.js in this way:

after line 81 

 execute: function(queryUrl, queryParams) {
	PM.Map.clearHighlight();
        var self = this; 
...

a much better solution for my work is to modify pm.map.js in this way:

line 162

 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 );
		  
				
    },

the previous solution gives problem with History Navigation...

according to your project extension you have to set the coefficent which
adjust the extent of the selected features:

var minx = (ext[0]**0.9999*);
		var miny = (ext[1]**0.9999*);
		var maxx = (ext[2]**1.000*1);
		var maxy = (ext[3]**1.0001*);

an even better solution is to use the config parameters
  <pointBuffer>
  <shapeQueryBuffer>

and adapt them to the coordinate system used for your map and typical 
scales used for tour application...
