I am trying to make a swf file with a single wms layer background. When =
I do the colors get reduced to what looks like 8 colors. The script I am =
using is below along with the map file. I can send the swf and a jpeg if =
anyone needs a sample of what is going on.

$img =3D $map->draw() or die('Unable to draw map');
