[mapserver-users] Drawing a Line From A Set Start Point to End Point

[wallacher at innomis]

Hi Lena, if tried this code and it works.

$mypoints=array(
   array(1,1),  // 1. point
   array(40,1),  // 1. point
   array(40,80),  // 1. point
   array(1,80),  // 1. point
   array(1,1),  // 1. point
)
$myline=ms_newLineObj();
foreach ($mypoints as $key => $value) {
    $myline->addXY($value[0],$value[1]);
}

//Create the shape object that will be added to the layer
$shape=ms_newShapeObj(MS_SHAPE_LINE);
$shape->add($myline);
$this_layer_tornado->addFeature($shape);
