[xep-support] XEP compared to FOP 0.94

Philippe,

I haven't tried adding bitmaps to SVG. Doesn't that defeat the purpose?

We use the following:
<mediaobject>
<imageobject role="fop">
<imagedata fileref="../images/junk.svg"/>
</imageobject>
<imageobject role="html">
<imagedata fileref="../images/junk.png"/>
</imageobject>
</mediaobject>

You can always compose a small demo illustrating the problem.

Regards,
Roy

Roy,

Thanks for the explanation, I will check this. The "bitmaps" (usually 
PNG images) imported from our SVG graphics seem also to have gone away 
during the PDF rendering. Any thoughts about this ?

Thank again for the help,
Regards.
