Preserve EPS transparency ?

[Bingo]

I am still trying to find a way to get my background color right when converting from EPS to PNG.
I thought about preserving the transparency from my EPS image, but unsuccessfully.
I tried :
nconvert -out png -o test.png -dpi 20 -transpcolor 255 255 255 test.eps
and
nconvert -out png -o test.png -dpi 20 -transpcolor 255 255 255 -colors 256 test.eps
Did I forget some parameter ?

Thanks !
