[mapserver-dev] Polygon Background Color

[Conor McCauley]

Hi Folks,

I'm having a bit of trouble setting the background color on my maps which
render polygon shapes based on Oracle spatial data. It always seems to
render transparent.

I've tried setting the IMAGECOLOR on the MAP element, the BACKGROUNDCOLOR in
the CLASS elements, but nothing seems to work. I've tried everything it
seems, so any help or advice would be much appreciated.

Kind Regards,

Conor.

Here is a sample map file:
