Subject: Re: [docbook-apps] Persian, Arabic or Hebrew FO output, need toget writing-mode=rl-tb

Hi Bob,
Thank you for you answer! I tried your first approach and it works fine, but I have some right-to-left alignment problems,

1.   TOC, I should have from the right side, first the text, the dots line and then the page number.
I found the template in fa/toc.xsl, and put it in my customizing layer and changed it,
but it doesn't work, could not find some variables.
I need to get in my FO output file,  in toc part formatting like this:

<fo:block text-align-last="justify" text-align="start" end-indent="24pt" last-line-end-indent="-24pt">
         <fo:inline keep-together.within-line="always">
                      <fo:basic-link internal-destination="intro">
                          <fo:page-number-citation ref-id="intro"/>
                         <fo:leader leader-pattern="dots" leader-pattern-width="3pt"
                         leader-alignment="reference-area" keep-with-next.within-line="always"/>
         <fo:inline keep-with-next.within-line="always">
                    <fo:basic-link internal-destination="intro">
                    1. ARABIC TITLE
2. In "calloutlist", "callout" I should put them to the right side, from there, first the number and then the text.
Can I have them in my customizing layer? I checked the fo/callout.xsl file, is this the template name="callout-bug"?

3. Everywhere in Stylesheet, when it has text-align="left", it should be change to "right", and vice versa.

3. Could Stylesheet support fully the @dir attribute? Or the Stylesheet get too complex to support these features.

I checked all of these with Antenna House and my modified FOP trunk-version, and is the same.

Thank you indeed!

There are several opportunities in the stylesheet to set a writing-mode property.  It is easier at the global levels.  Here are two options:
1.  The root.properties attribute-set is applied to the fo:root element.
2.  The template named set.flow.properties can be customized to add properties to each fo:flow element.
I have enabled Arabic and Hebew for Antenna House using both methods.  In one case, I created a customization for Arabic documents in order to select fonts and adjust formatting for right-to-left alignment.  In that case, I put the writing-mode and language properties in the root.properties attribute-set.
In another case, I used set.flow.properties to select a writing mode, based on the document's lang attribute.  I called the template named l10n.language (in common/l10n.xsl) to convert the document's lang attribute to a standard form that matches one of the locale filenames in the common directory (ar for Arabic, for example).  Then I used that value to choose a writing mode.  I also made sure the language property was set at the top level.
At the block level, it gets more complicated because there are so many templates that generate blocks.  There is no single place to add properties for all fo:block elements.
The stylesheet does partially support the @dir attribute, but only on inline elements.  See fo/inline.xsl for examples.

Hi Bob,

thank for your answer! Actually I am working on a patch for Apache FOP so that fop
will be able to create well-formated Persian, Arabic or Hebrew output files.
My aim is to have open source documentation system for languages like Arabic
with complex text layout writing system.

On my FOP trunk version, I can create Arabic PDF files
like this one
but I should have in my FO files the correct writing system. The problem is not just having the correct shapes
and glyphs but it should be able to apply Bidi Algorithm on each paragraph.

Antenna House's XSL Formatter needs also to have writing-mode="rl-tb":


Arabic Arabic Arabic


Can I control this by my customizing layer? Is this implemented depending on writing-mode "dir" attribute?  

Kindest regards,

Kia Teymourian

Hi Kia,
It would help if you mentioned what XSL-FO processor you are using. If it is FOP, then you are out of luck, because FOP doesn't support writing-mode properties that enable you to publish Hebrew or Arabic. 
If you use RenderX's XEP or Antenna House's XSL Formatter, then you can publish Hebrew and Arabic, and it is easier than you think.  The Unicode ranges for those languages identify the glyphs as needing to be set right-to-left, so the formatter will do so automatically without having to set writing-mode or use bidi-override.

Subject: [docbook-apps] Persian, Arabic or Hebrew FO output, need to get writing-mode=rl-tb

could you please tell me how can I get in my .FO output file, the attribute writing-mode="rl-tb"?
I need to have in my .FO file something like this:

<fo:block font-size="14pt"  font-family="Tahoma"  line-height="14pt" 
  space-after.optimum="12pt"   writing-mode="rl-tb" >

I send my XML file with dir="rtl" attribute to the XSLT
processor, and the dir="rtl" is just once defined in the root tag
<book dir="rtl">  or <article dir="rtl">.
Is this feature implemented?
Or should I add this part in my customizing layer?

How can I get
<fo:bidi-override> objects in my .FO output? Is bidi-override implemented?
