mapshot drops legend on mapview of stars object with factors

[przell]

Hi @tim-salabim, thanks for supporting stars objects with factors now in mapview! That's an awesome feature! I am trying to generate a mapshot from a mapview object that is showing a stars object with factors. Mapshot drops the legend. Here an example:

lc <- read_stars(system.file('tif/lc.tif',package='stars'))
tst_mv = mapview(lc)
tst_mv # legend there
mapshot(x = tst_mv, file = "test.png") # legend gone

Not sure what's happening... I'll look into it

@przell with https://github.com/r-spatial/mapview/tree/429-update-to-webshot2 this seems to work. You can install that branch with

remotes::install_github("r-spatial/mapview@429-update-to-webshot2")

and then

library(mapview)
library(stars)

# Sys.setenv("CHROMOTE_CHROME" = "/usr/bin/brave-browser") # just in case chromote cannot find a suitable browser

lc <- read_stars(system.file('tif/lc.tif',package='stars'))
tst_mv = mapview(lc)
tst_mv # legend there
mapshot(x = tst_mv, file = "/home/tim/Downloads/test.png") # legend gone

produces

Please let me know if this works for ou too.

Can also confirm that it's working after installing remotes::install_github("r-spatial/mapview@429-update-to-webshot2")

Thanks!

Hi, I have the same issue where mapview (version 2.11.0) drops the legend when I save it as a png. I don't think this branch exists anymore. How can I resolve this issue? Thanks.

[tim-salabim]

I think it should work if you

remotes::install_github("r-spatial/mapview")
