#8 zoomtoextent

[Anonymous]

A simple function that calls zoomToExtent does not
work for some reason. Its works the first time, but
second time onwards it fails. It seems that after calling
this function the extents are not saved in $IMSmap .

from the email.

function zoominToEnvelope() {
global $IMSmap;
//echo "i am in zoominToEnvelope ";
$mapX1=$_GET['mapimgx'];
$mapY1=$_GET['mapimgy'];
$mapX2=$_GET['mapimgx2'];
$mapY2=$_GET['mapimgy2'];
echo
$mapX1. " " .$mapY1. " " .$mapX2. " " .$mapY2;
//$cx=abs($mapX2-$mapX1);
//$cy=abs($mapY2-$mapY1);
//echo " " .$cx. " " .$cy;
//$center=$IMSmap->getMapPoint($cx,$cy);
$arr2=$IMSmap->getMapPoint
($mapX2,$mapY2);
$arr1=$IMSmap->getMapPoint
($mapX1,$mapY1);
//$testEnv = $IMSmap->getExtent();
//echo " testenv" .$testEnv->maxX;

$x1=$arr1[0];
$y1=$arr1[1];
$x2=$arr2[0];
$y2=$arr2[1];
//$center=array();
//$center[0]=$x2-$x1;
//$center[1]=$y2-$y1;
$IMSmap->zoomIn(3);
$IMSmap->pan($center);
//echoEnvelope($x2,$y2,$x1,$y1);
//echoEnvelope($mx1,$my1,$mx2,$my2);
$newExtent = new aimsEnvelope
($x2,$y2,$x1,$y1);
$IMSmap->zoomToExtent($newExtent);
//$IMSmap->setExtent($newExtent);
// $IMSmap->zoomInByEnvelope($x2,$y2,$x1,$y1);
