In ikiwiki 2.66, SVG images are not recognized as images. In ikiwiki.pm,
|
|
the hardcoded list of image file extensions does not include ".svg", which
|
|
it probably should unless there's some other issue about rendering SVGs?
|
|
|
|
The 'img' plugin also seems to not support SVGs.
|
|
|
|
> SVG images can only be included via an `<object>`, `<embed>`, or
|
|
> `<iframe>` tag. Or, perhaps as [inline SVG](http://wiki.svg.org/Inline_SVG).
|
|
> The [[plugins/htmlscrubber]] strips all three tags since they can easily
|
|
> be used maliciously. If doing inline SVG, I'd worry that the svg file
|
|
> could be malformed and mess up the html, or even inject javascript. So,
|
|
> the only options seem to be only supporting svgs on wikis that do not
|
|
> sanitize their html, or assuming that svgs are trusted content and
|
|
> embedding them inline. None of which seem particularly palatable.
|
|
>
|
|
> I suppose the other option would be converting the svg file to a static
|
|
> image (png). The img plugin could probably do that fairly simply.
