Kind regards,

Comment 4 Sebastian Hölz 2014-01-16 16:21:25 UTC 
I have the same problem when using an SVG created with Inkscape. I was able to track this down to the following line in the SVG:

<tspan
   style="font-size:65.00091553%;baseline-shift:super"
   id="tspan6747">-3</tspan>

Here, the font-size is specified in "%", which I think is incorrectly interpreted by LibreOffice as a pixel-size. 

If I manually change this to let's say "10.5px" it looks better, even though the formating is still not correct.

I have taken a look at the SVG-file, which is already posted as attachment 79148 [details] to this bug. According to the header this file was also created using Inkscape. It also uses the exact same syntax with the font-size being specified in % of the main font-size:

    <text
       font-size="12pt"
       x="97.300003"
       y="148.5"
       id="text76"
       style="font-size:15px;fill:#000000;font-family:helvetica">SO<tspan
   baseline-shift="sub"
   font-size="75%"
   id="tspan78"
   style="font-size:75%;baseline-shift:sub">2</tspan>
Cl</text>

Sebastian

PS.: This is in LO Version 4.1.4.2, Win7

Adjustment to attachment 79149 [details]

I have taken attachment 79149 [details] and manually removed the font-sizes, which are specified as % and replaced them by px (e.g. font-size="75%" replaced by font-size="12px"). This resolves the issue of the huge fonts. The chemical formula is now almost rendered correct, but if you take a closer look you will see that baseline-shift="sub" is ignored. It seems that LO does not interpret all text attributes which are part of SVG 1.1 ...
