Is it possible to use a image (SVG oder PNG) from web (http) to use it as maker icon in QGIS?

In my case: Hiking Trails in OSM sometimes have a symbol as way marking (wiki:symbol). Here is one: https://commons.wikimedia.org/wiki/File:LDB-blau-OSM.svg I would like to mark my OSM hiking trail (imported from OSM using ogr2ogr) with that symbol. Just typing in the URL is not working:

enter image description here

Finally I would like to use the data defined override, to get the right symbol for the trail, using concat('https://commons.wikimedia.org/wiki/File:', "wiki_symbol" )

  • I do not have an answer. So I can only suggest that you download the picture as a workaround.

It works but you have to make sure to use the correct URL.

You have a link that points to a website (html file) containinge a link to the SVG: https://commons.wikimedia.org/wiki/File:LDB-blau-OSM.svg,

So you should use the correct path to the SVG file itself:

https://upload.wikimedia.org/wikipedia/commons/d/d2/LDB-blau-OSM.svg

So be sure to concat the correct path to the symbol: concat('https://upload.wikimedia.org/wikipedia/commons/d/d2/', "wiki_symbol") and the attribute wiki_symbol must contain the string LDB-blau-OSM.svg, see:
