[Mapserver-users] bug #316 and ms4 missing functions

[Paul Spencer]

Twan,

The format of the mapfile has changed somewhat.  Two of the changes 
relate to your problem.

The symbol is now part of a new style object, that is part of a class 
object.  Color objects are no longer referenced by index because of 24 
bit support, you now have an API to set the RGB color directly.

This means that you would make the following:

$co = ms_newClassObj($lo);
$co->set("name", "mysym" );
$st = ms_newStyleObj($co);
$st->set( "symbol", $mymap->getSymbolByName('star') );


$co->label->backgroundcolor->SetRGB( 255, 255, 255 );

The migration guide that explains these and other changes is at:

http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?MigrationGuide

I recommend that you investigate the README in the mapscript/php3 
directory for specific API details.

I don't know how difficult back-porting the postgis query bug would be.

Cheers,

Paul
