sam2p mentions that "alpha channel and transparency supported only for
Indexed images: only one color may be transparent"
http://www.inf.bme.hu/~pts/sam2p/
This effectively means that sam2p does *not* support real alpha channel,
since indexed images such as GIF support a single "special" color for
complete (100%) transparency, as opposed to various 'cellophane' colors
as permitted when a full alpha channel implementation is provided.

Hi Jean-Pierre,
[...]
A side conclusion of this thread (which was about svg export in general, not
specific to transparency),
it came out that inkscape export could only provide transparency with bitmap output (png).
Uwe pointed out that a recent version of inkscape provides a transparent pdf
output.
Another pointer, borrowed from the TexLive mailing list:
http://www.inf.bme.hu/~pts/sam2p/
I read there that
"sam2p can create EPS and PDF images with transparency"
Alas, sam2p starts from bitmaps, not from vector graphics...
