Hi, I keep trying to understand how does this work. I've drawn a schema from what Sergiu explained to me, what I've not used any standard to represent files, objects or processes. Please, could you propose any existing standard to try to better represent what is happening in the whole process? Thanks. Here it is the diagram... http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/Export As per the creation of the rtf/pdf or whatever format is possible to create from a xsl-fo document, it seems that there are two points to "inject" CSS rules for the formatting: pdf.css and/or any ad hoc template. Please, what do we need pdf.css? I've created a XWiki.PDFClass class with style as only property. Then, I've created a new document, instantiated XWiki.PDFClass and tried with some simple CSS rules like these: h1 { font-size: 30px; color: red;} h2 { font-size: 30px; color: green;} h3 { font-size: 60px; } Those rules work fine. Both in the template and in pdf.css. But I am not able to change margins, spaces before and after any hx paragraph,... I guess that any rule not accepted in pdf.css, won't be accepted in a template. After all, both set of rules are used by css4j. It this is true, only xhtml2fo.xls seems the only solution to get a customized output. Please, am I right? Is the use of templates documented anywhere? Sorry for posting such an amount of queries with no answer. To control minimally the appearance of a exported rtf file is a must for me right now. As Sergiu said, if we found a suitable library, to export do Word format could be contemplated. I don't know if the GSoC project on Office Import could relate with this export issue. But until any of these advanced issues crystallizes, please, could you point me to a way to getting at least the separation of paragraphs and font for paragraphs controlled by CSS during the export action?

Hi all,

I am working with a XE 1.3.8295 installation where RTF export works fine. But it will be great programmatically control the output layout (namely, pictures printed size, space before and after paragraphs or headings, space before and after pictures, footnotes,...

Please, could you point me in the right direction to face this requirement?

Thanks indeed for your help.

Ricardo

After a looooong monolog from Sergiu in XWiki IRC channel (thanks Sergiu!, I've started to draw a general schema for rtf exporting, but I am far from being able to understand it.

Time is running out and I do need to solve an apparently simple problem. Let me show you an example:

Here a simple dummy-document...

http://tinyurl.com/6n348s

Here the document exported as PDF...

http://tinyurl.com/6auum6

Here the document exported as RTF...

http://tinyurl.com/6npxe4

Here the content of pdf.css

h1 { font-size: 30px; } h2 { font-size: 25px; } h3 { font-size: 20px; } h4 { font-size: 15px; } h5 { font-size: 10px; } h6 { font-size: 10px; }

The first problem: I am not able to control the separation between paragraphs. I've tried a bunch of different margin flavors, but no one affects the apparently "default" settings. But font-size does work fine: it is possible to control it by modifying pdf.css

The "default" settings could be acceptable for the PDF version, but never for the RTF one (the one I need now). Please, see the examples.

So, please, if margins can not be set by modifying pdf.css, where must I look for the right place to control it?

And, why the pdf export does set a given paragraph separation and rtf works in a different way? Thanks!!!

Cheers,

Ricardo

Here it is the diagram...

http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/Export

I've modified the diagram with some Vincent's ideas. I've left the former version in the same page for further reference.

http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/Export

The diagram is not completely correct. The PDFClass's xhtmlxsl and fopxsl properties are not indicated correctly. The xhtmlxsl one overrides (replaces, if defined) the default xhtml2fo.xsl one and the fopxsl one overrides (replaces, if defined) the fop.xsl one. Also the style property doesn't replace the pdf.css file (and not pdf.class as mentioned on the diagram) but comes in addition to it. The resulting CSS is pdf.css + the css specified in the style property. Thanks -Vincent

All files are now solid green. Temporary ones are lighter than permanent ones. Solid lilac form contents a draft of XWiki.PDFClass: it only includes three properties, all derived from conversations with Sergiu and Vicent as I am not able yet of following XWiki code logic.

At this point, I don't know how xhtmlxsl and fopxsl properties can affect both production of the second intermediary XHTML document and the xsl-fo one.

Please, let me write down again a couple of questions I need to resolve:

1. How do I control <p></p> text by using CSS rules passed in either with pdf.css or with the style XWiki.PDFClass property?

2. How do I control upper and lower margins for the different levels of headings?

Thank you so much for your help,

Ricardo

Thanks, Vincent,

I've uploaded a new release http://tinyurl.com/5oatx4

Please, what process does use xhtmlfo.xsl stylesheet to transform intermediary XHTML 2 to the XSL-FO document?

a XSL Transformation.

At this point and considering that the resulting CSS is pdf.css + the css specified in the style property as you said before, the main issue is to know what CSS rules will be accepted there.

For instance, how could I control the appearance of text within paragraph tags? I've tried a number of options without success.

I don't know offhand sorry. Thanks -Vincent

Thanks!

The diagram is great. We should put it on xwiki.org. Here's what I would do:

* In DevGuide/Architecture, create a section about Export and put the diagram there with one or 2 lines of explanations. * In the AdminGuide/Configuration page, create a section for customizing the PDF/RTF output and include the image from the DevGuide/ Architecture page * In DevGuide/Architecture create a link to AdminGuide/ Configuration#... to point users to if they want to customize the PDF/ RTF outputs

Thanks! -Vincent

PS: You ask about how to represent processes and such. What I usually use is a FlowChart diagram for this. http://en.wikipedia.org/wiki/Flowchart. I have a FlowChart stencil in OmniGrafle. That said, I like your diagram as it is so no worries.

Glad to know you consider it can be useful! I will follow your guidelines as soon as possible. This Flowchart entry in Wikipedia is also an useful reminder about this topic. I used these symbols time ago, but I have not a clear idea about how to draw a "small" diagram with the pieces/languages described there. I will investigate further from this document. Thanks!

As far as I can see, the wiki is working correctly, but the rights are wrongly set. Guest is explicitly allowed view rights, and this implicitly denies view rights to all other users. It has always been like this.

It is a bug, but an unfixable one. The problem is that Radeox works with regular expressions, and regular expressions are not strong enough to capture an paragraph.

As for heading margins, I've been playing with a rtf file with different indentations and margins applied to headings and paragraphs. It seems to move fine at least between Word, Pages and OpenOffice. In Mac, Suse Linux and Windows.

Please, if you have any idea about how to modify heading margins, pictures size and <p> appearance, it will be really welcome! Thanks!

We could try to use a newer version of fop and css4j. I already updated fop in the trunk. css4j needs some testing, as the version we're using is pretty old (0.4, compared to 0.9.1), and the API might have changed. -- Sergiu Dumitriu http://purl.org/net/sergiu/

Thanks Sergiu. I will adjust the rtf export I've to produce now by hand and follow this issue as close as possible!

I managed to get those margins in pdf and rtf, using the 0.95beta release of fop (now used in the trunk). You should take into account the different bugs css4j has (most of them are still present in the most recent version). So, I have this working: h2 { margin-left: 2cm; margin-bottom: 1cm; color: yellow; } You can also use margin: 1cm; to set all 4 margins to the same length, but you cannot use margin: 2cm 0cm 1cm; to set different values. Also, you cannot use !important. You just have to upgrade http://repo1.maven.org/maven2/org/apache/xmlgraphics/fop/0.95beta-1/fop-0.95... and http://repo1.maven.org/maven2/org/apache/xmlgraphics/xmlgraphics-commons/1.3... (replace the older jars in WEB-INF/libs)

I am taking land with my new responsibilities and the new group clearly needs XWiki :-) And this css4j/Xalan/FOP thing is a key component of its current and future use.

One of my concerns is to establish a link between this world an a different issue we have talked about before: TeX and related environments (LaTeX, LyX,...). I don't know how these two worlds could link. Even if they are different worlds or just facets of the same topic. Or perhaps I am completely lost!

Well, TeX is different, because fop only accepts xsl-fo documents as its input, and TeX is a standalone applications hard to combine with a Java application directly. -- Sergiu Dumitriu http://purl.org/net/sergiu/

Yeap, but there must exist a "link" between xls-fo documents and TeX. I am sure you remember a former discussion about mathematical expressions... I think it has been not much active lately. The point is that in scientific environments. TeX or TeX-based "languages" are a must (nowadays), so we have to find how to move out our documents from XWiki to TeX and vice-versa. I must recognize that I have not advanced since the times of this named discussion :-( I'll catch up with this issue!

It depends on your timeframe. If you can wait till September then the new rendering mechanism should (hopefully) be in place. Please read http://dev.xwiki.org/xwiki/bin/view/Design/NewRenderingArchitecture if you want to know how it'll work. Thanks -Vincent

Remove the blank line between the 2 rules. The field is parsed and rendered, so the blank line causes a paragraph to appear there, which breaks the CSS.
