[pmapper-users] zoom to point and buffer problem

[Alessandro P. <al...@ti...>]

Hi,

this is a problem in ver. 2 and 3 with point layers:

when I open the map with
&zoomLayer=my_point_layer&zoomQuery=gid@1@241@1@0

The server issue a
Fatal error: <i>[MapServer Error]: setExtent(): Given map extent is invalid. 
Check that it is in the form: minx, miny, maxx, maxy

That's because the extent is set to the point itself (that obviously has no 
dimension).

I thought that the pointBuffer was applied here too, but it isn't.

Are there any workaround or maybe a patch in initmap.php applying pointBuffer 
to the extent is a better solution in this case?

        // Apply buffer (in units of features)
        //$buffer = 20000;   // <<<<<<<<<<<<<<<<<<<<<< ADAPT VALUE 
<<<<<<<<<<<<<<<<<
        // ABP: set buffer for points
        if ($this->qLayerType == 0) {
            $buffer = $_SESSION["pointBuffer"];
        } else {
            $buffer = 0.05 * ((($mExtMaxx - $mExtMinx) + ($mExtMaxy - 
$mExtMiny)) / 2);
        }
