[Mapserver-users] Need Urgent Help on PHP/MapScript >> ms_newPointObj()

[Merlos]

Try this. It works for me.

<?php

$my_map= ms_newMapObj('data/test2.map');

$pt = ms_newPointObj();
$pt-> setXY(5,5);
$img = $my_map->draw();
//Inline is a POINT layer.
$layer = $my_map->getLayerByName('INLINE');
$pt->draw($my_map, $layer, $img, 0 ,'yuhuu');


$url = $img->saveWebImage();

echo "<img src=\"$url\" alt=\"Yuhuu!\" />";

?>

Regards. Merlos.
