using FOP under JRE 1.6
Hi, i try to start FOP (0.94) without xalan under JRE 1.6 If i right understud the docs, i can omit xalan and co. if i use JDK > 1.4 (JAXP) Without using xalan i get problems: java.lang.NoClassDefFoundError: org/apache/xml/utils/URI$MalformedURIException at org.apache.fop.fonts.FontCache.addFont(FontCache.java:246) at org.apache.fop.render.PrintRendererConfigurator.getFontInfoFromConfiguration(PrintRendererConfigurator.java:313) at org.apache.fop.render.PrintRendererConfigurator.buildFontListFromConfiguration(PrintRendererConfigurator.java:196) at org.apache.fop.render.PrintRendererConfigurator.configure(PrintRendererConfigurator.java:93) at org.apache.fop.render.pdf.PDFRendererConfigurator.configure(PDFRendererConfigurator.java:70) at org.apache.fop.render.RendererFactory.createRenderer(RendererFactory.java:187) at org.apache.fop.area.RenderPagesModel.(RenderPagesModel.java:70) at org.apache.fop.area.AreaTreeHandler.setupModel(AreaTreeHandler.java:126) at org.apache.fop.area.AreaTreeHandler.(AreaTreeHandler.java:101) at org.apache.fop.render.RendererFactory.createFOEventHandler(RendererFactory.java:224) at org.apache.fop.fo.FOTreeBuilder.(FOTreeBuilder.java:99) at org.apache.fop.apps.Fop.createDefaultHandler(Fop.java:147) at org.apache.fop.apps.Fop.(Fop.java:82) at org.apache.fop.apps.FopFactory.newFop(FopFactory.java:226) … I use my own generated font metrics. They are configured in fop.xconf file. After debuging i found that the class "CachedFontInfo" has a dependency to org.apache.xml.utils.URI.MalformedURIException which is a xalan class.

Re: Fop layout question
Thanks Jeremias. This is exactly the type of information I was looking for. I will try to work out a few examples of my own the coming days to make sure I understand what is going on.

RE: filtering SVG
Jeremias,
I might have to resolve to that...i am having difficulties inserting text
into an existing element...
So far I have, but I still need the first template to apply template so I
can get to the second template...
marker { overflow:visible; }
Tx (also Pascal).. I will probably try the URI Resolver..

In addition to what Pascal suggested: You can plug in a custom
URIResolver. When the image package redesign is completed you should
also be able to return a DOMSource as the result of URI resolution. At
the moment you have to return an InputStream.

RE: filtering SVG
Hi, I had a similar problem in the past: replace all texts in SVG with localized one. This can be done at the XSLT stage: - parse the SVG with the document() function; - use fo:instrem-foreign-object instead of fo:external-graphic HTH, Pascal > -Message d'origine- > De : Raphael Parree [mailto:[EMAIL PROTECTED] > Envoyé : vendredi 16 novembre 2007 09:55 > > Hi, > > I was wondering if the following is possible and what would > be the best approach.

I don't like just piping log output to the user/caller. I have different ideas that should address the needs better than just a massive stream of log output. I like to differentiate between information for the FOP developer (logging) and for the FOP user (processing feedback). Please track the following Wiki page: http://wiki.apache.org/xmlgraphics-fop/ProcessingFeedback I'm probably getting to that in December or January at which point I'll initiate a serious design discussion. > The Log instance that raises the events should ideally be tied to the > FOUserAgent. > > Still unsure how to fit in the static loggers :/ > Maybe, to minimize the amount of refactoring, FTM we could do: > -> implement a simple org.apache.fop.apps.StaticLog > -> initialize all static loggers in static blocks and call > LogFactory.setAttribute() to use this type > > The StaticLog.info() events and above, could get overloads that > accept an instance-based logger (the one tied to the user agent) on > which they register those events. > Should you decide to take steps in this direction, since this is > becoming a rather pressing matter, IMO, I'm willing to invest some > time in this as well. For a client, I've hacked together something using ThreadLocals in Log4J so you can grab all log output per rendering run (as long as we don't do multi-threading inside FOP). http://www.jeremias-maerki.ch/download/fop/log4j-threadlocal-appender.zip You just have to implement ThreadLocalLogInterceptor to get the log output. One instance per rendering run. Before you call FOP, you call ThreadLocalLogSetup.installLogIntercepter() with your interceptor instance in the same thread that you will run FOP. After the rendering run, uninstall it again using ThreadLocalLogSetup.uninstallLogIntercepter(). This only works for Log4J so you have to configure Commons Logging to use Log4J. But this could easily be adapted to work with Commons Logging directly. But maybe that helps as a work-around until we have a proper processing feedback mechanism.

In addition 0.94 should break at the '/' character automatically, i.e.
it should break typical URLs. However, it will not break on '.' not
followed by whitespace (if it did if could have very unfortunate
effects on numbers like $12.50).

filtering SVG
Hi, I was wondering if the following is possible and what would be the best approach. We use a lot of SVG (exported from Visio). These SVG always need a manual fix to make line ends (arrow etc) visible: I would like to insert this style element to each svg during generation. The SVGs are added as external images. So I would need some sort of image filter to add this to the DOM tree of the SVG. Is this possible, and what would be the best approach.? Tx., Raphael
Re: Fop layout question
Of course, there are some more properties that can influence the placing of the text so the following calculations are only exemplary and only restricted to the scenario you posted. However, there's one problem with your example to start with: You specify font-family and font-size on the inline, but the dominant baseline is actually defined by the font on the parent block which is undefined in your example (depends on parent values not visible in the example). So let me rework your example to make it simpler. I assume you want to do this to exactly position text on a page, maybe to fill out some form. That's why you need exact information on how the placing is performed. Correct me if I'm wrong. The adjusted example: Some test The block-container has fixed positioning on coordinate 0/0, so it has the upper left corner in exactly the upper left corner of the sheet of paper. The first block has a margin-top which is internally translated to a space-before of the same length with its conditionality subproperty set to retain (it is always shown). Let's assume for this example that the font is "Helvetica". Here are the essential font metrics for Helvetica: ascender = 718 descender = -207 These values can be found if you look into the XML font metrics file that you can generate from a font with PFMReader and TTFReader. We need to calculate some other helper variables: font box = font-size * (font.ascender - font.descender) (area tree: text/@bpd) block-height = font-size * line-height (area tree: block/@bpd) half-leading is defined through the line-height property. half-leading = (block-height - font box) / 2 (area tree: lineArea/@space-before and lineArea/@space-after) baseline = font-size * ascender (area tree: text/@baseline) So not the absolute coordinate baseline of "Some test": x = 0 (because it's left aligned, no start-indent) y = aa + half-leading + baseline aa = block.margin-top = block.space-before = 20 pt = 2 mpt bb = line-height = 1.2 font-family = Helvetica cc = font-size = 12 pt = 12000 mpt font box = 12 pt * (718 - -207) = 11100 mpt block-height = 12000 mpt * 1.2 = 14400 mpt half-leading = (14400 mpt - 11000 mpt) / 2 = 1650 mpt baseline = 12 pt * 718 = 8616 mpt y = 2 + 1650 + 8616 = 30266 mpt Some pointers to the spec: http://www.w3.org/TR/xsl11/#line-height http://www.w3.org/TR/xsl11/#area-line (line areas are much more complicated than the above example shows!) I hope that's what you wanted.

RE: BreakingAlgorithm Problem
Hi Kumar,
thanks for your hint. I wrote a template, which checks if there are some
non-letter-characters (like '.', '/'; etc.). If this is the case, I concat
the string after each character with Unicode Zero Width Space(''),
but then FOP 0.93 overlaps letters. I also tried FIGURE SPACE ('&x#2007;'),
but then FOP does break it half way ... very strange. Here my code snippet:
Any idea, why FOP0.93 is doing it that way?
Thanks in advance,
