SVGs are renderes to PNG by the mediawiki software. As Internet Explorer can not
display transparent areas in these images, he showes them with some sort of
default-color (some blue-gray thing). This lookes pretty ugly and prevents the
svg-images to be used in articles. (lots of coat of armes and logos are effected
by this). (ex.: [[Image:CDU_logo.svg]])
It is possible to define a background color into the png image, which is not
shown by modern browsers. In gimp you can choose "Hintergrundfarbe sichern"
(german version, should be something like "save background color") when saving
as png to do this. White would be a good choice. Result: Forefox, Opera and
others show still everything perfect (transparent), Internet Explorer showes a
For an example with different images see URL above.
Maybe this can be fixed easily within the configuration of the svg renderer.
Confirmed. This bug makes transparent SVGs really ugly
(using IE on Windows)! Thus, I changed the importance of
Note that IE7 (now available as a englis-only beta also working in non-English genuine Windows XP or
2003) will now support alphatransparency in PNG images ;
The Commons people delete redundant images of PNG, and leave only the SVG - and
it makes troubles at the Hebrew Wikipedia, and probably also at many other
projects - within Internet Explorer 6 users, and one of the sysops there also
requested everyone not to replace the PNG images to the SVG ones (if they are
transperent, of course), and uploaded the PNG image to the local server. Now
Commons is useless with these images. That's a critical bug for the success of
That's the reason we should fix that bug soon.
Any commons admin doing that should be immediately desysopped.
librsvg 2.14.0 renders its PNGs with a nice white background chunk.
Upgrade should resolve this.
Now this bug should be Worksframe, isn't it?

I meant, shouldn't it?
Ok, action=purge can now be used on an image page to force images to rerender.
(Be careful about caching; make sure it reloads the new image!)
Thanks for your work, it's a lot better now!
I see the progress for several images, but the crest on
<http://de.wikipedia.org/wiki/Bild:Sin_escudo.svg> still looks ugly with IE6
(grey question mark instead of white one)
Use action=purge *on commons*.
