dynamic annotation

[Oliver Lichte]

Hi,

try something like this:

where, $map:mapObj

  ...
$lay = $map->getLayerByName( "NICHEAD2" );

$cls = $lay->getClass(0); // works only if the class is the first defined
$cls->setText( "Your new text" );
...

You may get problems with the alignment of the text in the image but other 
attributes of the classObj can be changed similar.


Cheers,
Oliver
