hello,
iam new to mapservers and iam trying to display the selected point in terms
of lat-long. i get errors in the code which i tried to implement
if ( isset($HTTP_POST_VARS["mapa_x"]) && isset($HTTP_POST_VARS["mapa_y"])
) {
$my_point = ms_newpointObj();
$my_point->setXY($HTTP_POST_VARS["mapa_x"],$HTTP_POST_VARS["mapa_y"]);
$reference_click = pix2geo($mapa_x,$mapa_y,$map->extent,
$map->width,$mapobj->height);
function pix2geo($pix_x,$pix_y,$extent,$width,$height) {
$pix_x_geo_x = ($extent->maxx - $extent->minx)
/ ($width - 1);
$pix_x_geo_y = ($extent->maxy - $extent->miny)
/ ($height - 1);
$geo_x = $extent->minx + $pix_x_geo_x*$pix_x;
$geo_y = $extent->maxy - $pix_x_geo_y*$pix_y;
$my_point = ms_newPointObj();
$my_point->setXY($geo_x,$geo_y);
return $my_point;
}
