--------------------------------------------------------------
[[email protected]] the width and height are set on the svg as well:
{code:java}
<svg xmlns="http://www.w3.org/2000/svg"; width="12cm" height="12cm"> {code}
I missed the auto on the fo:external-graphic, hence why I closed the ticket,
because I was able to fix the issue with minor changes to the SVG.
-I'll have a look at this whenever I'm able to. I'll reopen it now.-
I had the chance of looking into this further, and I still think FOP does not
have an issue. FOP is using the dimensions given by the SVG and using that to
determine how much space to give the image. I do believe the problem lies with
the fact that FOP uses by default 72dpi as a resolution, while most browsers
use 96dpi. When I set the _source-resolution_ conf to 96dpi, I no longer see
the clipping on the side.
I've attached a PDF and a slightly altered SVG. The PDF was generated using the
changed conf I mentioned above. If you open both the PDF and the SVG, you are
able to see that they look similar.
