[ka-Map-users] "Given map extent is invalid"

[Paul Spencer]

Hi,

it seems odd that you have units DD and are not using degrees for  
your extents.  Try loading the map file with this php script:

<?php
dl('php_mapscript.dll');  //adjust to the appropriate version
$oMap = ms_newMapObj('c:/ms4w/apps/kamap-0.1.1/htdocs/global.map');
$oImg = $oMap->draw();
$szURL = $oImg->saveWebImage();
echo "<img src=$szURL>";
?>

If that works then there is a bug in ka-Map.

Cheers

Paul
