Table-footer breaking across page
I have a 3 row table footer that I want to appear at the bottom of the table content. The table runs over 3 pages. The header repeats on each page but I have put in table-omit-footer-at-break="true" because I only want the footer on the last page. This works fine *except* when the 3 rows of the footer actually hit the end of a page. When this happens, the footer is pushed onto the next page (properly) but I get the header and 29 blank rows of table body before the table footer appears. Is there another property I should be using? Thanks, Phil
Memory leak? (was: 'Possible' memory leak on fop-users)

Taking a snapshot right after FOP has finished, would reveal the last one, provided that the reference tree Root->AreaTreeHandler->XMLWhiteSpaceHandler has not yet been completely cleared/released. Was re-thinking this particular phrasing, and had a closer look... Moved it to fop-dev, because of the importance. Firstly, this looks like a damned circular reference, indeed! That's my bad, sorry. Since the reference to the last block is not released unless the reference to the Root's AreaTreeHandler is cleared, this keeps the entire ancestry alive, up to the PageSequence, which itself holds a reference to the Root? :| ... :( Definitely worth a try to release the reference XMLWhiteSpaceHandler- >Block as soon as possible. OTOH, looking deeper, I'm strangely surprised no-one saw this one before --so surprised even that it makes me think I'm missing something : Root.addChildNode(PageSequence) results in a reference to the PageSequence being kept in the Root's list of child nodes. Right? AFAICT, this reference is *never* released as long as the Root object is alive, so it seems like currently, our 'split up in page- sequences' performance hint is complete and utter bogus...? Sorry to disappoint you all. Good news is, both are rather easily fixed --at least on the surface. Either: a) override addChildNode() in Root, so that the PageSequences don't get added to the List at all; maybe only under certain circumstances (unresolved forward references?) should this be needed b) call Root.removeChild(this) in PageSequence.endOfNode() c) call Root.removeChild() from the next PageSequence's startOfNode() Unfortunately, I am a bit stuck in the marker-property rework ATM -- FOText in a marker turns out to be a little bit more difficult than the FObj-subclasses... Decided to take care of the dubious static FOText.lastFOTextProcessed in one go, so that will make a nice set of improvements 8) I'll make it a priority to clear this up after that, if nobody beats me to it.

PDFTranscoder custom fonts
Hi, I have a question about using custom fonts when converting from SVG to PDF using PDFTranscoder. There is a zip file containing all the information available at http://www.flerwin.net/fopquestion.zip It includes * Java source code * SVG trying to convert to PDF * XML generated from TTFReader * The TTF font * Configuration file read in via Avalon The problem that I am having is that I cannot add the Tahoma font, so that the PDF contains the same font as that in the SVG. As you can see in the code, I have followed the example given at http://wiki.apache.org/xmlgraphics-fop/SvgNotes/PdfTranscoderTrueTypeEmbedding Am I doing something wrong? I am currently using SVN Trunk version of Batik and SVN Trunk version FOP Thanks Antonio Broughton - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Well, best to avoid posting large attachments to the list, as you will force every subscriber to download them. Maybe we could also move this whole discussion to Bugzilla, and add those files as attachments over there. Benefit is that, even when we don't immediately have the time to look further, there will be a constant reminder to look into this. But this is how the reference tree to the object looks like : Root -> AreaTreeHandler -> XMLWhiteSpaceHandler -> Block -> TableCell -> CommonBorderPaddingBackground -> CondLengthProperty -> CondLengthProperty Hmm... So, are you sure *all* these CondLengthProperty instances have this same reference tree? Or did you check only one? Attempt at interpretation: In itself, *one* of these trees at a given point in the process is certainly nothing to worry about. The WS-handler keeps a reference to the current block. That block references its parent, a TableCell, which references its own properties, and a length-conditional property holds a reference to its corresponding property --e.g. padding-before<->padding-top, depending on whether 'before' maps to 'top' given the writing-mode and reference-orientation). I wouldn't be surprised to see a lot of these trees occur in the course of the process, but if I esteem correctly, in a literal snapshot, there should be only one. There is only one handler which has one reference to the current block. That reference is never explicitly cleared, but strictly speaking, it never needs to be since it is re-used. Taking a snapshot right after FOP has finished, would reveal the last one, provided that the reference tree Root- >AreaTreeHandler->XMLWhiteSpaceHandler has not yet been completely cleared/released. At most, we could try nulling this out explicitly in PageSequence.endOfNode(), but I'm not sure if that is going to make much of a difference. It *may* result in those objects being GC'ed sooner, but that ultimately depends on the JVM. :/ Not sure if I am doing the right thing, but I'm willing to help or contribute further on this. Something that could also be of use to judge this completely is an example of a FO-file (note: NOT the XML+XSLT, but the result of the XSL transform, because that ultimately is the input for FOP) Is it possible for you to generate one with Xalan or Saxon? Use a source XML with non-confidential dummy data. It doesn't need to be large, but just enough to give us an idea of what a typical document looks like for you --so we only have to imagine it a thousand times larger. (Or did you already send one to this list in the past?) Thanks, Andreas - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Font problem
Thanks Chris and Pascal. It worked when both ttf and xml files were in the same folder in my case it is fonts. -- View this message in context: http://www.nabble.com/Font-problem-tf2009831.html#a5525988 Sent from the FOP - Users forum at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[GT2006] Update! Cocoon GetTogether 2006 (Oct 2-4,Amsterdam)
*** * * * Cocoon GetTogether 2006 * * * * October 2nd to 4th * * * * Amsterdam, The Netherlands * * * ** www.cocoongt.org *** Hi all, Here's a little Cocoon GetTogether 2006 update! First of all, a big Thank You to everyone who responded to my emails! Ideas for talks --- Here's the (long!) list of subjects for sessions that we all came up with: - Success stories (why someone chose Cocoon, for what, what was great and what not?) - Comparison of Cocoon with other web frameworks - Why should I upgrade to 2.2? - A "meet the Cocoon devs" session at the hackaton for users. This session should be moderated and the topics come from the participating non-committers. - Perspectives of the portal block, relations to other Apache portal projects - Some shorter, flashier presentations of what you can achieve with Cocoon, right from the core developers - A session with "kowledge flashes", 5 to 10 minutes per subject - A "guided tour" through Cocoon where Reinhard interviewed Carsten and Sylvain about the internals - Some demos of actual Cocoon sites, with explanations of why, how, etc - Optimisation techniques, (efficient, performant Cocoon) across the whole lifecycle of an application - The secret gems of Cocoon (what do people not know about that is really cool) - Interactive apps, authentication, user tuned content - How to get involved (find out what the community needs from contributers) - Some sessions that focus on technologies that are often used together with Cocoon, with Guru's: - Maven 2 - Spring 2 - FOP 0.92 - Cocoon and Web Services/SOA - Lepido - Some howto's / best practices for - Configuration - Using Spring - Building Cocoon - 10 Reasons to use Cocoon - A "What's new in 2.2 and how to use it track" with different topics, 5 to 10min per topic. - What's up for Cocoon 3.0? - The Funky Cocoon AJAX tour (with lots of samples!) - A session like "moving from xsp and sitemap actions to flowscript and jxtemplate" to introduce existing users to the latest Cocoon techniques and guide them in upgrading their older bits of code - A short (!!) introduction to OSGi (what's all that fuzz about?!) - Best practice + case studies for cocoon based Intranet Portals - Integration of Cocoon and Open Source Workflow Servers, Cocoon based Workflow applications in general - Cocoon Forms: "meta form application" (let the users create form based applications by assembling cocoon forms with the help of CF) - Short, practical case studies: high-level architecture, integrating Cocoon, etc. - How to NOT get lost in Cocoon technologies: flow, binding, xsp, jxtemplate, cforms, authentication, portal, etc. - How does Cocoon provide login, authorization, menu, form processing, templating, integration with backends (database)? - How to create a "typical" project with cocoon, regarding sitemap hierarchy and organization, class model, deployment, artifacts, where do flows scripts must go, etc? - Case studies showing large web applications - Cocoon for 'non-java' professionals and Cocoon project management - What is the required knowledge in order to hire a professional that should work in a cocoon project? - Does separation of concerns work in a real world situation? - Reducing risk when building large projects with large teams - How to tweak Cocoon for performance - Real numbers on cocoon performance, real hardware and real deployment topology (load balancing, session replication) - A caching tour. How can I use caching effectively and what can I cache - Measuring performance. How can I know at what speed my cocoon site is running? - The Cocoon toolset: tools that can help shorten development time / tools for testing / monitoring And a final note from Bertrand: "Talking to community members, I get a feeling that we're using Cocoon in wildly different ways, and I think it's one of its major strengths - let's show this at the GT!" (+1 from me!) Many thanks to all who shared their thoughts - it gives so much more insight in what everyone's expecting from a good Cocoon conference. Great! Now, all we have to do is do it 8-) Audience There was some interest from the FOP guys at the ApacheCon Europe to come by at the CocoonGT and (ab)use our hackaton for their own efforts. I guess Cocoon could only benefit from that, so I'd say they are more than welcome to do so! Also, I'd welcome anyone from Forrest, Lenya, Daisy or any other Cocoon-related project at this years Cocoon GetTogether. The more, the marrier! Rooms - We have the possibility of renting an extra (smaller) room during one or more of the 3 days, almost for free. So, we *could* do parallel sessions of some kind Any thoughts? Sponsoring -
Re: Possible memory leak
Andreas, Thanks again for your time. Nothing specific in using call-template instead of apply-templates. Coming back to profiling, I tried taking a snapshot of the heap after a FOP conversion using Jprobe and Jprobe reports "CondLengthProperty" as the loitering object. Not very familiar with analyzing this further. I have a snapshot file and some screen prints of Jprobe, not sure how to post it in this forum. But this is how the reference tree to the object looks like : Root -> AreaTreeHandler -> XMLWhiteSpaceHandler -> Block -> TableCell -> CommonBorderPaddingBackground -> CondLengthProperty -> CondLengthProperty Not sure if I am doing the right thing, but I'm willing to help or contribute further on this.

latest build
I downloaded and built FOP from the SVN yesterday (26-07-2006). The build appeared successful and I copied all the files into my working folder. Now when I do a PDF that contains png graphics (barcodes generated from BarCode4j) they turn out as fuzzy unreadable images. I have attached a pdf and a png to demonstrate. Did something break with rendering png images in this build, I was using a build from 02-06-2006 before this. I am viewing with Adobe Reader 7.0 on an XP pro SP2 box.

I've spent almost two hours now trying to reproduce the behaviour in a small example, but I didn't manage it :-( I've tried several ways, but each time both the alignment and the line breaks looked fine. I'll do my very best to deliver a small example because it wouldn't be possible to show the "big one" anyway - my employer probably wouldn't be that happy about it ;-) Maybe it has got to do something with the font I'm using (FreeSans) and for which I created the metrics. I will try to play around with that a little bit. Anyway, thank you very much again for your advices :-) Cheers, Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
