transparent symbol

[Lluís Garcia i Mestres]

Hi list,
I'm trying to implement pixmap symbols transparent. I was following the 
current documentation but it's a litlle confusing with the inde color. In my 
case, I have a white background that I want to skip. How can I figure out 
what is my index color for a white background?
  The outputformat of the map is the following:

OUTPUTFORMAT

NAME jpeg

DRIVER "GD/JPEG"

MIMETYPE "image/jpeg"

IMAGEMODE RGBA 

EXTENSION "jpg" 

TRANSPARENT ON

END
  and the symbol definition
 SYMBOL
NAME 'eolica'
TYPE PIXMAP
IMAGE 'eolica2.png'
TRANSPARENT 1
END
