Hi Lex,
thanks for your comments. It looks like the problem is related to the
generated docbook XML or the toolchain processing this XML.
The generated docbook XML contains elements like:
<mediaobject>
<imageobject>
<imagedata fileref="C:\docdir\asciidoc\images\myimage.png"/>
...
If this is converted either to xhtml or to LaTeX, this path appears
unchanged in both output files. For xhtml, the output won't work because
<img src=" C:\docdir\asciidoc\images\myimage.png " ...
contains an invalid URI.
For the LaTeX backend, pdflatex chokes at the path with backslashes, even
on Windows.
>From my point of view, the either generated docbook XML is wrong with
respect to the *fileref *attribute, or the postprocessing of the XML has to
take care of the conversions.
Adding my own macro to docbook45.conf is a workaround, though.
Thanks
Thomas
