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.

Subject: Re: [docbook-apps] Persian,
Arabic or Hebrew FO output, need to get writing-mode=rl-tb
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
http://user.cs.tu-berlin.de/~kiat/fop/TestOutPut.pdf
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":
<fo:block-container
writing-mode="rl-tb"
font-family="Tahoma"
language="ar">
<fo:block>
Arabic
Arabic
Arabic
</fo:block>
</fo:block-container>
Can I
control this by my customizing layer? Is this implemented depending on
writing-mode "dir" attribute?
Kindest regards,
Kia

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.

[docbook-apps] Persian, Arabic or Hebrew FO output, need to get

Hi,
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"
>
تیموریان
</fo:block>
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?
Thanks,
Kia
