I've tested lots of things but this pixmap transparency does not seem to
work.

My outputformat is PNG24.

I've replaced the transparent pixels of my gif file with white (adding
the white color to the color palette of the file). Then I added
TRANSPARENT attribute to the symbol. But it's still visible.

I've tried with PNG file type for the symbol. Still not working

I've added a TRANSPARENT ON to the OUTPUTFORMAT. Then the white pixels
around the bullet are grey but not transparent at all.

...

What's the next step ? Using only squared symbols ?
