RE: FOP Extension to handle Wiki Syntax
We see what you are trying to do, what would be probably better rather than creating an extension, How about a more helpful / generic pre-processor Wiki -- XML And then you can add your own pre-processor extensions to say add BBCode-XML Then you can use your wiki-XML to change the wiki page into a valid XML document to be transformed into FO by xsl and then to pdf. Example: **this is a header** -- para style=header2this is a header/para Kindest regards Theresa Forster Senior Software Developer - To unsubscribe, e-mail: fop-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: fop-users-h...@xmlgraphics.apache.org
Table cell not wrapping - how to insert zero width space?
I came to know from the other discussion forum that table cell text not wrapping can be solved by inserting zero width space. I want to know how to implement this and if there is any example then it will help. Please note that the text to be put in PDF in our case is dynamic. Thanks in advance.

Or maybe hyphenation. Working well for me.

Re: FOP Extension to handle Wiki Syntax
Thanks for your answer, Today, I made a working prototype with Saxon by using http://www.saxonica.com/documentation/extensibility/integratedfunctions.xml ExtensionFunctionCall s. It's a bit complicated since Saxon-HE 9.3 (or was it 9.2?) dropped support for calling static java methods from the stylesheet. It's also a pity that javax.xml.transform API does not provide a standard way to register additional functions, I will have to make specific extensions for Xalan AND Saxon and usage within stylesheets will differ too based on the transformer library you will use. Well, I know those problems are not directly related to FO(P) but I just wanted to rant a bit about it. Regards, Kalgon Andreas L.

Perhaps then folks would understand better that FOP is fundamentally an XSL-FO - output format processor. FOP did start that way, if I recall correctly. There was a time when including the possibility to feed XML+XSLT as input was considered a big win. I actually think going back makes little sense, especially given that the usage pattern for embedding is basic JAXP. Even if you feed FOP plain FO, an identity transformation is used nowadays, also when invoking via the CLI. Way back when, using the CLI with plain FO actually did not use the XSLT processor at all, just the XML parser. Another point would be that XSL-FO itself defines nearly all its examples in terms of XSLT that transforms semantic XML to FO... *shrug* It is easy to see how newcomers get confused. Ultimately, we could just respond with a link to the website, where it is darn' well explained what the recommended practice is in case of problems (i.e. submit FO, not XSLT; if the problem is XSLT, go to Mulberry etc.). Nonetheless, I'll probably never get tired of pointing it out to people --even if they do seem to lack the most basic web browsing skills sometimes... ;-) On 14 Jun 2011, at 12:09, kalgon wrote: snip / What I would like to know is how I can build a tree of FONodes (blocks, text, table...) programmatically while parsing my wiki text and feed that tree to the FOP engine. I've been looking at ElementMapping, XMLHandler and the likes but I can't get a good grip at how those are working. If somebody could point me to a good and complete tutorial on FOP extensions or send me a nice example of how to do it, that would help me a lot! In this particular case, I would agree with the assessment that a FO extension would not be the most efficient/productive choice. While I can explain how to insert a new Block into the stream, I still would not encourage it. The quick and dirty approach, with probably the highest probability of success, would be to just send the appropriate SAX events back to the FOTreeBuilder. So, your code would have to be full of: Attributes myAttrs = new AttributesImpl(); myAttrs.addAttribute(, font-weight, font-weight, CDATA, bold); ... builder.startElement(FO_URI, block, fo:block, myAttrs); ... builder.endElement(FO_URI, block, fo:block, myAttrs); I am not entirely certain it will always work, but I don't immediately see another way that would cheaply allow you to get potential property inheritance right, or have your content behave properly if it is contained in a fo:marker... This shows that FOP's API simply isn't designed with that in mind. Internally, it is meant to parse formatting objects from XML source. FO extensions only allow you to go so far. The extension mechanism is mainly meant to allow you to handle custom, foreign XML (= non-FO, e.g. to plug in a handler for your custom child object of fo:instream-foreign object; prime examples SVG, MathML, Barcode4J...). Translating flat text markup into FO (or more generally: XML), not so much. Don't get me wrong. I like the whole idea of being able to translate MediaWiki fragments directly into FO. Seems a very useful thing to have, however... Given the power of XSLT/XPath 2.0 to handle regex processing of unparsed text and consistent generation of valid XML(FO) nodes (even when the nesting levels get too difficult to follow for the human mind and its programming logic), this seems like THE weapon of choice for such a job. With a bit of imagination, one can easily keep this generic enough to work for a multitude of source XMLs. Just write a small stylesheet library to translate arbitrary MediaWiki markup into the corresponding FO syntax, and plug it into the main stylesheet. Sequences and xsl:functions are truly powerful stuff! If you feel generous, make it publicly available for everyone to try out/correct/extend... I'm quite sure it will get all the attention it deserves. We would gladly link to it from our website
Re: Complex Script Support
I am pleased to inform you that Glenn Adams updated his work with a new patch. This patch includes the following: * bug fixes * new layout engine tests for right-to-left writing mode * new generic indic script processing support * new devanagari script processing support See milestone Patch 4 at http://skynav.trac.cvsdude.com/fop/report/6 for further details. The update has been imported into FOP's code in the Temp_ComplexScripts branch. The new code is available at the URLs cited below. You can download the binary distribution or the fop jar file from http://people.apache.org/~spepping/. You can check out the source code from FOP's subversion repository, http://svn.apache.org/repos/asf/xmlgraphics/fop/branches/Temp_ComplexScripts. You can follow the work at FOP's Bugzilla, bug nr. 49687, https://issues.apache.org/bugzilla/show_bug.cgi?id=49687.

Re: Problems with FOP and image
Hi thanks for the help yeah i haven see that its was .java and not .class, ok
then if i follow correctly what you are saying then it has to be something
like this
BufferedImage newImage = new BufferedImage (C:\Logo.jpg)
ImageIO.write(BufferedImage, JPEG, jpegImageFile) jpegImageFile will be
the XML call rigth something like C:\Logo.jpg)
and another thing
Warning(1979/26): fo:table, table-layout=auto is currently not supported
by FOP
but in my xslt it ike this fo:table table-layout=fixed width=100% so
i dont now what its causing the ploblem

No, the bufferedImage is an in-memory instance of BufferedImage holding
the bits of the image. In the case that you have to read it from one
place and write it to another.

Did you go through all your jars looking for 'CLibJPEGImageReaderSpi'.
My greatest suspicion is that you don't have all your jars lined up.
Which jar(s) do you think supplies these?
What is your environment: just windows or do you have any tools like
cygwin?
The jpegImageFile would be the filename in your xsl the
external-resource. If you're just using a file that is already in place
you don't have to re-write it.

If
so, I suspect netbeans is registering services for you. Your own

will have to make a call to one of the
IIORegistry.registerServiceProvider() methods.

And given assumptionA, you're java code is correct in terms of FOP
and
your configuration isn't for ImageIO. Show your ImageIO related
code
and are you sure it's in your app. Use the logger to show a
message
when you add your loader. Or list all ImageIO services:
IIORegistry.getServiceProviders()
