Here is an example of a map with code generated svg images as symbols.
The quick and dirty script does:
- aggregate all features from input point layer with same geometry
- calculate min/max times and values for whole set
- create svg files for every feature with filename based on id
- create a la
There is this library to make it easier:
https://pypi.python.org/pypi/svgwrite/
And since it is python, you can use the standard code editor in QGIS (or
an external one if you prefer).

This would be great also for nautical charts to render light sectors from
S57 data.
Could existing code editor be used to construct the svg with some python
svg library?

Hi all,
Great idea indeed.
Here is another example of "dynamic" SVG, used here to render PNG as
symbols in QGIS. Not with expressions but with a Python method.
https://gist.github.com/mdouchin/d66191ccfadd74cff3f0
It is derived of the work of Nathan Woodrow:
http://nathanw.net/2016/02/04/live-svg
That's a cool idea. It would be similar to the HTML element in print
composer, where one can also mix static and dynamic HTML code - with
Expressions. It would be very flexible.
Maybe this could even be further extended to also allow Javascript
inside the SVG code (like a web-browser does). The H
Actually, we already have a "template" concept in SVG, if you look at
the SVG shipped with QGIS, they have things like fill="param(fill)"
allowing to have the filling color as a user parameter.
That could be easily extended to also support feature's attributes and
expressions.

Hi Raymond,
Well - 90% is some default Inkscape/RDF junk. You can trim this down to
four lines - header, the path element and the closing SVG element.
Also, some of the styling parameters are unncessary, as SVG has default
values - not necessary, to write fill-opacity:1;, because this already

Hugo,
That would be way cooler!
For now, I just write generated svg files to a temp directory and add
links to them to every feature.
Strings might get long though. Here is for example the code from my
dummy image (1.4kb):
http://purl.org/dc/elements/1.1/";
xmlns:cc="http://creativecommon
It would be also cool to be able to directly use a string as image
content for a marker (rather than just for the filename).
That should be quite easy to do.

Raymond,
Code generated SVGs is a pretty cool idea. Would be super keen to see that
once you have something!

Pretty cool - so we can deliver script-generated SVG code instead of a
filename? Nice!
Care to do a blog post with some example? This sounds quite exciting to
me.

Hi Hugo,
It works! Thanks a lot!!
This is exactly what i was looking for, but somehow could not find.
Here is a little example with some fake svg's:

Now I will script generating svg based on real data.

Hi Raymond,
Do you have an example how such a visualization could look like? Kind of
a mockup?
In QGIS master, Matthieu Pellerin added additional simple markers now
(e.g. half/third/quarter circles, squares, triangles, etc.), e.g. to
create wingcharts. The combination of custom anchor points, o
Thanks Hugo, I will try to get this to work.

are maptips an option or do you need always on images?
in 2.16 you'll be able to have full html maptips which would solve your
issue.

Dear developers,
Can I somehow show custom images for each point feature on a map,
similar to the layer diagrams?
Having locations with a few sensor values, I'd like to generate a custom
image for every feature (for example svg or png) and have it displayed
on my feature.
I've come up with some
