[Mapserver-users] marker not transparent

[uli]

I have a pixmap marker symbol with 4 paletted colors. I wish the color with
index 1 to be transparent.

When I choose an OUTPUTFORMAT with IMAGEMODE RGB the color is not
transparent. With OUTPUTFORMAT  -> IMAGEMODE PC256 it works fine (but I need
RGB-colors).

I tried to export the marker as GIF and PNG without any difference.
Drivers tested were  DRIVER "GD/PNG" and DRIVER "GD/JPEG" - without
difference.

Is this GD/MS normal behavior, a bug or my mistake?
