There is the possibility to save the style of a layer in a geopackage:


This style can be read by QGIS without additional code. But is there a way for QGIS to read SVG symbols from a gpkg?

I could write the SVG by code, but reading should be done without additional code.

    Which version QGIS are you using? Mar 19, 2020 at 9:03
  • @etrimaille: I didn't know it yet. Would be a partial solution, but one would have to deliver an additional (proprietary) file for the GeoPackage. Mar 19, 2020 at 9:18
  • @ MortenSickel: The version is not so important. I am looking for a way to exchange data with others with little effort Mar 19, 2020 at 9:20

    The version is always important. I see many people working with QGIS 2 (not even 2.18), QGIS 3.4.0... nowadays! I'm giving you an answer using QGIS 3.4, maybe you are not using it? How can I guess?And in your question, you are mentioning only SVG, not additional proprietary data.

I was very interested by myself, to find out how we can package a QGIS project with all external dependencies inside a GeoPackage database. With the help of the "indispensible" expression editor, it's possible to reference SVGs/images stored in a BLOB column and base64 encode on-the-fly.

  1. Create a GPKG layer (i.e. "svg") with 2 columns (name:text,image:binary[blob])

enter image description here

  1. Store your SVG images in the layer "svg" (click on the "..." button to embed the SVG):

enter image description here

  1. Reference the SVG symbols in your vector layer (i.e. table "locations", column "type")

enter image description here

  1. Use SVG Marker styling with the following expression to display your SVG symbols

'base64:'|| to_base64(attribute(get_feature( 'svg','name',"type"),'image'))

enter image description here

  1. Praise the Qt developer, who has added support for inline SVGs and inline images!
