[mapserver-users] Setting scale on mapobject

[Alexandre Dube]

Hi Pietro,

  You could try this (untested):

    $nScaleDenom = 50000; // your scaledenom value
    $oCenter = ms_newPointObj();
    $nX = $oMap->width / 2;
    $nY = $oMap->height / 2;
    $oCenter->setXY($nX,$nY);
    $oMap->zoomscale($nScaleDenom, $oCenter, $oMap->width, 
$oMap->height, $oMap->extent);

  Regards,

Alexandre
