[Mapserver-users] PHPmapscript 4, color

[Dylan Keon]

Erich,

Check out the Migration Guide page on the Wiki.  There are examples of 
color handling, as well as other changes to make when moving from 3.5 to 
4.0.  http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?MigrationGuide


This should help (copied from the Wiki page):

   Most class parameter definitions are now handled by the new style
   object.

     For example,

         $classObj->set('color', $map->addColor(255,255,0));
         $classObj->set('size', 18);

     is now implemented as

         $style = ms_newStyleObj($classObj);
         $style->color->setRGB(255,255,0);
         $style->set('size', 18);
