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

Thu Nov 18 18:30:18 PST 2021

Hi Luigi,

ps.map (or g.gui.psmap/File > Cartographic Composer) is certainly an
option. You can also have a look at m.printws in addons (mentioned in the
ticket you linked), but it suffers from the same issues as the normal
display since it is using d-commands.

https://grass.osgeo.org/grass78/manuals/addons/m.printws.html

I have tried to put individual layers rendered as SVGs together manually.
That was too difficult to match, but perhaps if you clip vectors to a
computational region you can match those.

Just to be clear, are you saying the ps driver (with
GRASS_RENDER_PS_TRAILER etc) didn't work for you?

Best,
Vaclav
