You mean Batik will have pdf-transcoder.jar and ps-transcoder.jar in
their distributions? Not the source, right?

What about factoring out the code for the transcoders and supporting
classes (like fonts) into a separate container/subproject accessible by
both the FOP and Batik teams? XML-Commons, maybe? That way we could
encourage the Batik guys to participate in the future development of the
PDF- and PS-related SVG stuff. Just a thought.

+1. We could give the transcoders a bit more visibility on our site.

Not really at the moment. But as soon as I have this licensing issues
and an initial release of my barcode package behind me, I wanted to go
into full Avalon-refactoring mode. And that brings some more Avalon
stuff into FOP especially the renderers, fonts and image support.

I'd like to propose this:
- I'll modify the build so we can generate a raw pdf-transcoder.jar as
  it is now (needs avalon-framework.jar), but along with another
  (pdf-transcoder-all.jar) that also contains the necessary Avalon
  classes.
- I'll do the documentation involved.

ATM the PFM parser and the apps subpackage are the only ones that can be
left out, I think.

Wouldn't it make sense to work with the Batik team to get the PDF and PS
transcoders into their test infrastructure so we have some good feedback
and can quickly improve on the quality to match the AWT output?

I haven't set up the PS transcoder, yet. But I could do that soon. I'm
still hoping for George to send in a patch for his PostScript work.
