Laurent C.:
Hello,
I'm using a Python script to generate maps for publication by setting
GRASS_RENDER_FILE and running the different d.* commands. Is it
possible to add opacity to some of the layers?
Dear Laurent,
not a direct answer, but you might want to read

Also, the r.out.png tool has a "-t Make NULL cells transparent" flag.
Kind regards and thank you for your excellent work I've seen elsewhere.
Nikos
