GeoPDF raster on Windows

[mdsumner]

I cannot get anything from the GeoPDF raster driver on Windows.

Any ideas?

Create a PDF (it won't have georeferencing or CRS, but that shouldn't matter).

##
library(magrittr)
library(sf)
st_drivers() %>% dplyr::filter(grepl("PDF", name))
#   name      long_name  write copy is_raster is_vector   vsi
#   PDF   Geospatial PDF  TRUE TRUE      TRUE      TRUE FALSE
library(sf)
example(st_read)
pdf("myfile.pdf")
plot(nc[1], reset = FALSE)
dev.off()
st <- stars::read_stars("myfile.pdf")
## file not found

Create a GeoPDF directly with gdal_translate to check it's not the PDF variant from R:

system("gdal_translate myfile.pdf ext-geo.pdf -of PDF -a_ullr 0 10 10 0 -a_srs '+init=epsg:4326' ")
system("gdalinfo ext-geo.pdf")

No good

stars::read_stars("ext-geo.pdf")
Error in CPL_read_gdal(as.character(x), as.character(options), as.character(driver),  : 
  file not found

I've tried the full path, with escaped back slash and single forward slash. All works fine on Linux.

Hi @mdsumner! Your examples works for me with devel sfversion.

nc <- sf::st_read(system.file("shape/nc.shp", package="sf"), quiet = TRUE)
pdf("myfile.pdf")
plot(nc[1], reset = FALSE)
dev.off()
#> png 
#>   2
st <- stars::read_stars("myfile.pdf")

Not for me, it doesn't matter if it's CRAN or dev. Are you on Windows? What's the set up? Can you share sessionInfo()?

[etiennebr]

I'm on Ubuntu. See my session info below the reprex (unfold).

[mdsumner]

Ok no problem, just this is about Windows.

[etiennebr]

Ah, sorry, I missed that important fact!

[mdsumner]

I do it all the time!
