[Qgis-user] SVG files in QGIS print layout

[Andreas Neumann]

Hi Doug, 

Can you share your SVG file? I'd like to have a look at it. Inkscape
sometimes does peculiar things to SVG text elements (like adding complex
matrices where they aren't really necessary). That might lead to issues
with QGIS, because QGIS doesn't support the full SVG profile, but only
the SVG tiny part of the specification. 

Inkscape also offers several different optimizations when saving to
different SVG versions. One might be better suitable for QGIS than the
other. But I'd need to see your file first to give recommendations. 

Unfortunately, you are limited to the SVG tiny profile when importing
SVG into QGIS. QGIS relies on the QT library for SVG support and QT only
supports SVG Tiny (and from this specification only the static part).
See https://www.w3.org/TR/SVGTiny12/ 

There is nothing easy we can do to improve the situation. The solution
would be to improve the qt library first to also render more than SVG
tiny, more features from the full profile that Inkscape normally
produces. This would require financial investments into the QT library
and also patience, until this ends up in QGIS, because it would then
require a newer qt version. 

Greetings, 

Andreas
