Re: [docbook-apps] Persian, Arabic or Hebrew FO output, need toget 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 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.

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" >

  
&#x62a;&#x6cc;&#x645;&#x648;&#x631;&#x6cc;&#x627;&#x646;
    

</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 Teymourian
