[GRASS-user] d.mon start=cairo multi-layer PDF, PS, SVG output

[Luigi Ponti]

Dear list,

I am replying to myself just to say that I hit the same issues as shown at:
https://trac.osgeo.org/grass/ticket/3033

My apologies for not checking that first.

As I keep running into this problem, but there is not a lot of discussion
on it, probably people have found other ways to deal with it (e.g., ps.map,
which what I will try next).

Also, I noticed that the Python way was also explored:
https://discuss.wxpython.org/t/wx-image-postscript/25813

which I was actually about to ask…

Kind regards,

Luigi
