[mapserver-dev] MS_FOLLOW

[Alan Boudreault]

Robert,

To change the angle propety to MS_FOLLOW, I think you should use something 
like:

$oLabel->set('autoangle', MS_FALSE);
$oLabel->set('autofollow', MS_FOLLOW);
 
Unfortunately, the "autofollow" property in PHP/Mapscript is only available in 
MapServer 5.6. If you are building mapserver manually, the following patch 
could be easily applied:

regards,
Alan
