So the problem does not appear to be with FOP--at least on this issue--but with either your SVG or with Batik. FOP uses Batik for SVG--if your SVG portion is not working with Batik/Squiggle, it won't work with FOP. Batik is another library, another team--I don't handle it. In this debugging, what I need next from you is an SVG file using Batik extension elements that runs fine in Squiggle, but when put within FOP fo:instream-foreign-object, won't run. If you can do that, then we can resume debugging within FOP.

Well, not the Batik extension element mapping in particular, but I had been embedding the maintenance version up to now. Switched it to 1.0dev and basic functionality seems to be A-OK.

I'm not sure which of these problems are already being worked on, and as I most certainly do not want to end up 'spamming' fop-dev with a bunch of pseudo-bugs, I'll just name a few here.

I still need to check the spec run a few tests to see whether this behaviour is compliant: CSS seems to silently presuppose that if no bg-c is explicitly defined, table-cell would inherit the value of its parent - in this case table-row, but as none was specified there either, one would expect it to be the color of table-body... ] 3. break-before -after seem to have no effect Read you later.

(I just want to check to what extent I'm beginning to understand the internals of the application...) I was happy to see you going through the source code. Also welcome to the FOP-DEV list. Main issue is that we could not just switch from SVGDOMImplementation to ExtendedSVGDOMImplementation as Thomas (I believe) had thought. The latter is not really a superclass of the former--they're different sets of elements with different namespaces. (To that end, the superclass-subclass relationship of these two classes in the Batik code does not seem correct to me.) So I just added in one more ElementMapping subclass in the fo.extensions.svg package for the Batik Extension elements. I'm not sure which of these problems are already being worked on, and as I most certainly do not want to end up 'spamming' fop-dev with a bunch of pseudo-bugs Don't kill yourself here--the majority of 1.0 is still unimplemented. I was strictly more concerned about the Batik extensions working for this particular point. (For sanity retention, I try to narrow my concerns to one or two topics for each week.) CSS seems to silently presuppose that if no bg-c is explicitly defined, table-cell would inherit the value of its parent - in this case table-row, but as none was specified there either, one would expect it to be the color of table-body... ] Well, not everything is inherited in the XSL FO standard--http://www.w3.org/TR/xsl/slice7.html#background-color says bg-c is not inherited (but evidently can be if inherit is chosen as a value, so I'm not sure how FOP should handle this.)

Currently we always distribute the 'many' jar files we provide a convenience batik.jar that just references all the other jar files. The simplest way to get the jar would be to clean the compile tree. Run 'build compile' then jar classes and 'resources'.

Re: Batik Extension/FOP problem
Hi Glen, So there already is such a constant: batik.extension.svg.BatikExtConstants.BATIK_EXT_NAMESPACE_URI. I shouldn't add this to ExtensibleSVGDOMImplementation as it is exactly that extensible. The set of Namespaces it supports is determined at run time based on the Service Provider Interface. I could add methods to query what namespaces have been registered with it but registration is actually on a per-element basis (namespace + localName) - so it might have one or two elemets borrowed from other namespaces. This isn't that big an issue at this point since the only extensions I am aware of are the Batik ones which are all in the above namespace. Do you want to add an interface for getting the list of namespaces that it has elements registered under (just SVG, Batik for right now)?

Also org.apache.batik.dom.AbstractParentNode does not allow adding child with different document object, I have to comment out if (n.getOwnerDocument() != getCurrentDocument()) in checkAndRemove() method. Pleae help me check what is wrong here. Probably you have add the batik extension into next release of FOP. Thanks. Jay On Fri, 5 Sep 2003, Andreas L.

( also because I haven't used Batik directly ) Does this happen with other graphic formats too? What versions (FOP Batik) are you using? Is FOP being run from the command-line - using the supplied shell script to set its classpath - or embedded? Check http://xml.apache.org/fop/graphics.html#batik to find out why I think these questions are important.

Re: Batik Extension/FOP problem
Hi All, I am trying to use batik extensions through FOP. I added BatikElementMapping and BatikObj objects into my FOP src and then registered them in the driver class but I am still getting some exceptions. Can anybody help me out ? I am trying to embed the flowText.svg ( provided by batik distribution ) into a simple fo document and then trying to convert into a pdf. As the exception is happening in batik it may be a version problem. Have you tried with the latest FOP rc. Swapan.

Re: Batik Extension/FOP problem
Yes. I am using the 0.20.5rc2. May be for the batik extensions to work through FOP, I need to tweak some batik code also??
