[mapserver-users] Mixed Mapfile and Mapscript (php)

[Yewondwossen Assefa]

Hi There,

 The way to set the colors in mapscript is :

   * add a color in the map object : $colorindex = $map->addcolor(r, g, b)

   * use the color index in your class setting : class->set("color",
$colorindex)

  Hope it helps,
