[mapserver-users] setextent

[Patricio Gigoux]

Can somebody say me? why the next or what is my wrong 
$map->setextent($extent2_to_set[0],$extent2_to_set[1],$extent2_to_set[2],$extent2_to_set[3]);
where:
$extent2_to_set[0]=342733
$extent2_to_set[1]=6295000
$extent2_to_set[2]=349772
$extent2_to_set[3]=6300000
but
$map->extent->minx=342733   
$map->extent->miny=6293979.345
$map->extent->maxx=349772
$map->extent->maxy=6301020.655

Thank in advance
Patricio
