Description:
The full text of the email above
Several text strings can be displayed overlapping to the point of being unreadable, but the graph remains intact. This happens in the conversion from SVG to PNG. To see it happen:
- Go to http://en.wikipedia.org/wiki/A-weighting and see the broken PNG there.
- Double-click the image to go to the file area and see the broken PNG there.
- Download the file Lindos2.svg
- Open the downloaded file in an SVG viewer that works, such as IE 7 with the Adobe ActiveX control that comes from the file SVGView.exe, that you can download from http://www.adobe.com/svg/viewer/install/main.html
You'll see the text displayed properly.
This and similar images were placed in the Wikipedia pages by Pete Skirrow of the Lindos company. In an email he said:
I made the original images you mention, as well as some others for:
http://en.wikipedia.org/wiki/Weighting_filter
http://en.wikipedia.org/wiki/Weighting
http://en.wikipedia.org/wiki/Robinson-Dadson_curves
http://en.wikipedia.org/wiki/Programme_levels
http://en.wikipedia.org/wiki/ITU-R_468_noise_weighting
http://en.wikipedia.org/wiki/Rumble_(audio)
http://en.wikipedia.org/wiki/A-weighting
I can tell you that they all came up perfectly for years, but became
corrupted a few months ago. This suggests to me that the problem lies in the
.svg to .png translator that is applied to all Wikipedia page images, so
that they appear on the page as .png
<snip>
I think someone updated the Wikipedia conversion software, and that
it is now incompatible with .svg files generated in OpenOffice. If you look
at the last page listed above you will see that this graph is not corrupted,
and I think this is because this one was created after I discovered and
started using the free software Inkscape, which I now use and recommend to
make drawings.

I'll attach the whole email.
Thanks for reading this far, and I hope someone can look into the module that does the conversion from SVG to PNG.
