i had a look in the spec today and it seems that it is impossible since
transparency can only be applied to objects or groups but not to a color
vector. So, we need to wait until PDF1.X supports this. If somebody has
good connections to Adobe please ask for this very feature.

P.S. If somebody has access to Adobe Illustrator then i could help
to know if it is possible there ;-)
