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

Dear all,

I am trying to get output image files in various formats using the Cairo driver, following some very useful Python scripting examples:
https://baharmon.github.io/python-in-grass

When I try to map vector layers (e.g., point data) on top of raster layers (say a digital elevation model);

if I use PNG output file extension, both vector and raster layers show up with points having transparent background,

if I use PDF, PS, or SVG output file extension, only the vector layer (drawn last) is shown in the output image with white background.

Maybe the PS driver is a better option?

Yet, I was reading this old grass-dev post that may be relevant:
https://marc.info/?l=grass-dev&m=146346954429631&w=2

Kind regards,

Luigi

Sample test function I am using follows:

def make_map(outfile_name,
fig_width,
fig_height,
bg_color: Optional[str] = None,
file_types: Optional[list] = None):
“”" Test ouput map figure.
PLEASE CHECK as PDF and PS output does not get vectors displayed on
top of rasters. “”"
background_color = bg_color or [NO_BG_COLOR]
extensions = [PNG] if file_types is None else file_types
for extension in extensions:
outfile = pathlib.Path(OUT_DIR).joinpath(f"{outfile_name}.{extension}")
grass.run_command(“d.mon”, overwrite=True,
start=“cairo”,
width=fig_width,
height=fig_height,
bgcolor=background_color,
output=outfile)
grass.run_command(“d.rast”,
map=“raster_layer”)
grass.run_command(“d.vect”,
map=“point_vector_layer”,
type=“point”,
color=“150:0:0”,
size=20)

all other display commands

grass.run_command(“d.mon”, stop=“cairo”)

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

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
