Can someone give fedora-docs-list an update about our ability to put out a 100% free, gcj-compiled DocBook toolchain?
I've totally lost track of where this is at or who was working on it.
Thanks - Karsten

I've been meaning to test this against Rawhide but haven't got to it yet. When I do, I'll report the status here. (I have a feeling there will have been improvements because of the Java2D work in GNU Classpath).

Yes, I have CCed Cameron and Francis who might have the most up to date status on all this. If we have a good description of what really must work then we can concentrate on those parts of gcj, classpath, batik and fop that are essential to the documentation team.
I installed FC6test3, but cannot find the fop package that Tom created (or did I only dream that he did? maybe it was never submitted?). We might need to import/backport some recent classpath CVS fixes into the FC6 libgcj to make it all work since I know just days ago some new support for batik went into GNU Classpath (hi Francis, hi Cameron).
Cheers,
Mark

Yes, I’ve just last week started to try to identify what Classpath problems are preventing Batik from working. Since the Fedora people will (presumably) only be interested in rasterising static SVG documents, this should avoid having to deal with any Swing issues just yet.
We are collecting the issues regarding FOP and Batik here:
http://wiki.apache.org/xmlgraphics/GnuClasspathCompatibility
One thing I have noticed during my limited testing so far is that the rasteriser (and the SVG browser, too) is running pretty slowly compared to on Sun’s JVM. My first guess would be a mismatch of ColorModels between what Batik is providing and what the Cairo layer underneath is exepcting (which was a problem for Batik running under Sun’s OSX JVM a while ago), but I haven’t checked into this yet.
Some simple files work, others don’t. I really have to do some more testing before knowing which areas need to be looked at. I will report back (and update the wiki page above) when I have found out more.
If the Fedora documentation people want to provide examples of the kinds of things they will be processing, that would help to prioritise the work.
I am not sure about the state of FOP running with Classpath. Jeremias Märki (CC’d) should know more.
Thanks,

22938 - java.awt.BasicStroke.createStrokedShape unfinished
is also done; I committed a patch for it a couple of months ago, but the ticket hasn't been closed yet (waiting for some feedback).

AFAIK, we pass everything to Cairo in premultiplied ARGB32 for image data, if that helps.
I've also run across some problems recently with our ARGB implementation, mostly with the ordering of bands (resulting in weird discolouration), but that doesn't sound related...
Some simple files work, others don’t. I really have to do some more testing before knowing which areas need to be looked at. I will report back (and update the wiki page above) when I have found out more.
I'll wait to hear.

Hi Cameron:
I'm going to leave your reply intact below, just dropping a note that I sent a separate message to fedora-docs-list summarizing the thread so far and calling attention to what we can do to help.
Of the tools-herders, some are busy with test3 packaging, but we certainly must have some people with documents they want to test (into PDFs).
I'll keep both lists informed, for now. Thanks,
Karsten

Yes, I never submitted my packages as they were major hacks. Building Batik from the JPackage RPMs is not really feasible, because of the web of dependencies (rhino brings in many), the worst one being maven. None of these dependencies are packaged in FC or FE. On the FOP front, the FOP developers have done work in CVS to eliminate com.sun dependencies, work that hasn't been released and packaged yet.
I'd recommend building Batik and FOP from CVS if you're trying these out since then you can configure out the rhino dependency, and so you're working with the updated FOP.
