Hi Paul,
As usual, there are several ways:
1. You can either create a new attribute called "OGR_STYLE" (see section
2.8 in the spec) that contains the style definition (see chapter 2 in
the spec)
2. or you create an external .ofs (OGR feature style side-file) as
described in section 2.7 of the spec
3. or you use the OGR support Classes as described in chapter 3 of the
spec.
All information is in the spec, incl. some examples.
I would probably use options 1 or 2 in your case. Option one can be done
in an SQL-Select query, where you create the OGR_STYLE attribute on the
fly with your query.
Greetings,
Andreas

Thanks Andreas,
Yes, I would like to automate it. I have read the page you suggested but I don't understand how to implement it with ogr2ogr.
Kind regards,
Paul

Hi Paul,
ogr2ogr usually doesn't care much about styling, unless you use ogr feature styles:
https://svn.osgeo.org/gdal/trunk/gdal/ogr/ogr_feature_style.html
Or you use QGIS 3.10* which has a nice GeoPDF export built in. But if you want to automate things, I understand that the automated solution might be better for your workflow.
*Disclaimer: QGIS 3.10 must be compiled with GDAL >= 3.0 and proj6, which as far as I know is currently not the case for QGIS Windows standalone builds. See also https://gis.stackexchange.com/questions/340030/create-geospatial-pdf-geopdf-is-greyed-out-in-pdf-export-options-in-qgis-3-10

Hi list,
I have a question on how to export a PDF file from PostGIS with a color on the lines instead of the default black lines. I have searched on the internet but have not reached all the way...
I have 2 tables that I would like to export into test.pdf (rivers and roads)
ogr2ogr -f "PDF" c:\Temp\test.pdf PG:"host=xxx.xxx.xxx.x user=yyyy dbname=testdb password=pwd" rivers roads
I would, for instance set like to set line width to 1 px and color to 4040FF on rivers,
Width 3 px and color FF4040 on roads.
Thanks,
Paul
