You might also want to try using the cairo driver directly, rather
than using d.out.file. E.g.:
export GRASS_CAIROFILE=out.svg
d.mon start=cairo
d.vect ...

Thanks to all for these suggestions and comments.
I will look at the options suggested by Andreas, and follow Glynn's comment
to explore why Cairo dropped to rasterization - it's good to know that
*that's* why I got raster output, rather than wrapping a raster being all
that Cairo does!

Ignoring the aim of Pete's graphical outputs, perhaps my advice will be
trivial, but quite often people want to keep vectorial formats very
"far" in the output process eventhough they don't have special
post-editing needs. I was of those till I understood raster formats

Hello fellow GRASS users,
Can anyone tell if is possible to
do image segmentation, like
eCognition or SPRING, in GRASS.
I did some reasearch, but I couldn't

Cairo falls back to rasterisation as soon as
Hi List!
I often use the tool r.watershed and I always wonder that it seems to be
not affected by the issue of flat areas . How it manages the surface
flows in low/zero slope areas?
Thank you in advance.

Hi Matthew,
just an idea : did you check if grass70 exists in your path and if so,
is it executable (you can type sth like ls -l /usr/bin/grass* in a term)
Yours,

Your data set seems to be small. If You really think it's a bug in
