Alexandre,
Do you have IMAGECOLOR "#000000" set at the MAP level? Also I would put
the background color as the first color in the mypalette.txt file and
see if that helps.

Hi,
== problem ==
I'm pretty sure I saw this problem on the list somewhere, but I
couldn't find the actual thread so here it is : while using
agg & palette option, when there's no data to draw, instead of having
the backgroundcolor drawn it's all black instead.
How can I go around this problem ?
== my actual need ==
I want to produce smaller images. Currently, my getMap renders a 66K
png image. With the palette, it's down to 17K but with a black background.
