Thybério,
as Markus said, you cannot proceed this way because your output map is
already involved in the patch process. So using the -a option, you must

Nikos,
as Maciek said, your image seems to need warping, so I fear you have no
other solution than georectify it.

Pete, sorry if I'm off board :

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,

Hello list,
is there anywhere a way to choose a linestyle (e.g. dots or hatches) for
displaying vector maps ? Did not find such option on the d.vect man

as a shapefile.

Hello Richard,
just a suggestion, though I'm not a bash expert :
k=10
while [ $k -le 250 ]; do
i=0
while [ $i -lt $k ]; do
image=`echo Background_$i.png`
your stack of operations on $image;
((i++));
done
k=$((k+10));
Oops,
checking for your reply, I notice an error in my code at line 3 :
replace i=0 with i=$((k-10))
Yours,
Vincent.

Bonsoir Étienne,
Je crois comprendre que ton problème se rapporte à l'identification de
zones sur des critères géomorphologiques. Peut-être pourrais-tu partir
sur un traitement avec r.mapcalc ou des outils comme r.reclass pour
lisser ta topo ou du moins discrétiser ta carte des pentes, afin
