[gdal-dev] GeoPDF and neatline

[Philippe Ghesquiere]

Dear all,

I would like to translate a GeoPDF into Geotiff.
Furthermore, I  would like to select the image area, given by the neatline.

Image samples are available on "FSTopo Map Products
<https://data.fs.usda.gov/geodata/rastergateway/states-regions/states.php>"
site.
Typical gdalinfo gives :

gdalinfo Boulder_400010515_FSTopo.pdf
Driver: PDF/Geospatial PDF
Files: Boulder_400010515_FSTopo.pdf
Size is 3262, 4050
...
Metadata:
  CREATION_DATE=D:20230213221000Z
  CREATOR=Esri ArcSOC 10.8.1.14362
  NEATLINE=POLYGON ((467455.095191925 4427281.84826825,467455.105581267
4442204.97588751,479233.89727774 4442204.58886474,479234.013428373
4427281.65662041,467455.095191925 4427281.84826825))


I searched various sites for information and ended with the following
commands :

gdalinfo Boulder_400010515_FSTopo.pdf|grep NEATLINE | awk -F= '{print
"id,WKT\n1,\"" $2 "\""}' > Neatline.csv
gdalwarp -of GTIFF -cutline Neatline.csv -crop_to_cutline
Boulder_400010515_FSTopo.pdf Boulder_400010515_FSTopo.pdf.tif


*My question :*
Is there a way to gdal_translate / gdalwarp the PDF file without EXPLICITLY
extracting the neatline ?

I tried to use the "*-oo NEATLINE=something*" option :
gdal_translate -of GTiff -oo NEATLINE="POLYGON ((467455.095191925
4427281.84826825,467455.105581267 4442204.97588751,479233.89727774
4442204.58886474,479234.013428373 4427281.65662041,467455.095191925
4427281.84826825)) Boulder_400010515_FSTopo.pdf
Boulder_400010515_FSTopo.pdf.tif

The option is ignored.
