Hi Nyall,
Thank you for having a look at the SVG symbol issues.
The SVG specification is very clear about what the default stroke and
fill color is. See http://www.w3.org/TR/SVG/painting.html#FillProperties
The default fill is black and the default stroke is "none" (no stroke).
Let's not invent something new, if the SVG spec is unambiguous.
If someone wants a white fill by default he could set the fill to
fill="param(fill) white"
Where white would be taken as default whereas in the case of
fill="param(fill)" black should be the default according to the SVG spec.
Note that the param() notation is not yet part of the SVG specification
- there is only a proposal at http://www.w3.org/TR/SVGParamPrimer/ -
which unfortunately never make it to a recommendation and was never
implemented by the browsers. The most likely way to get this into
browsers is through CSS - these days ... It would then not only work in
SVG, but also in HTML or other web standards.
Thanks,
Andreas

Hi all,
I'm currently working on fixing some issues with svg symbol rendering.
I'm wondering what everyone's thoughts regarding
http://hub.qgis.org/issues/10908 is?
Situation is:
- default fill color of svg marker symbols is white, outline is black.
- Up until 5 minutes ago, there was a bug regarding outline widths for
svg images. This meant that the width had to be ridiculously large to
be visible (eg 10-20x larger than desired). After fixing this bug the
outline is now visible in the svg image selector, so possibly that's
#10908 fixed. BUT - now I think the default svg marker width is much
too large (1 mm). I think this should be something more like 0.2 mm.
So I need some feedback. What should be the CORRECT default SVG marker
fill and border color, and border width?
(Personally, I'm leaning toward leaving it as white fill, black
outline, 0.2mm width.)
Nyall
