[MapServer-dev] Fwd: [MapServer-users] Filled SVG symbol after switching to Mapserver 8

Thu Dec 8 11:05:22 PST 2022

Hi devs: I'm curious if folks have any ideas on 8.0 changes that might have
affected SVG rendering. The msautotest SVG file renders fine as do some
other files I've created (circle with hole, star with even/odd fill rule).
So, this isn't a complete regression but something specific to a particular
type of SVG graphic. Rendering issue is consistent with AGG and Cairo.

Interestingly the SVG-related regression tests all pass using a more
complex SVG file than what you had shared. Using 8.0, the
msautotest/misc/data/Road_Works.svg  (
https://github.com/MapServer/MapServer/blob/branch-8-0/msautotest/misc/data/Road_Works.svg)
file renders fine as a point symbol while your marker_customers.svg does
not and matches your sample output. Using the current 7.6 branch, both
symbols render as expected as point symbols.

More digging will be necessary. Are any devs aware of specific changes
relative to SVG (or vector) symbol support?

I am using the camptocamp/mapserver 8 image. I have not changed anything in
the default configuration provided as part of the image.

Which SVG library are you using – RSVG or Cairo?

Hmmm… I’m not aware of any obvious changes between v.7 and v.8 that would
account for the change and nothing jumps out looking at your mapfile. Would
you be able to share one of your SVG graphics? --Steve

Hello,
after switching to Mapserver 8 my svg symbols started to be rendered as
filled:

how it looks now:

What can I do to render svg the good way?

Best,
