AW: [docbook-apps] Don't break chapter's to recto pages

Hello!

 

With “half-double-sided”
I mean that sometimes the pages switch between double-sided output(with odd and
even pages) and single-sided output. But this issue only arises without the
user.pagemaster! The main problem is that not every chapter wraps to the next
page.

 

Here are the complete
customized templates:

<xsl:template
name="force.page.count">

   
<xsl:param name="element" select="local-name(.)"/>

   
<xsl:param name="master-reference" select="''"/>

   

   
<xsl:choose>

         
<xsl:when test="$element !=
'chapter'">auto</xsl:when>  

      
<xsl:when test="$double.sided !=
0">end-on-even</xsl:when>  

      
<xsl:otherwise>no-force</xsl:otherwise>

   
</xsl:choose>

 
</xsl:template>

 

 
<xsl:template name="initial.page.number">

   
<xsl:param name="element" select="local-name(.)"/>

   
<xsl:param name="master-reference" select="''"/>

 

   
<xsl:variable name="first.book.content" 

     
select="ancestor::book/*[

     
not(self::title or

self::titleabbrev or

     
self::bookinfo or

     
self::info or

     
self::dedication or

     
self::preface or

     
self::toc or

     
self::lot)][1]"/>

   
<xsl:choose>

 

     
<xsl:when test="$double.sided != 0">

       
<xsl:choose>

              
<xsl:when test="$element = 'chapter'">auto</xsl:when>

         
<xsl:when test="$element = 'toc'">auto-odd</xsl:when>

Hi,

I'm
not clear what you mean by "half-double-sided".  Can you provide
a short example that illustrates the problem, and complete examples
of your two customized templates?

Subject: [docbook-apps] Don't
break chapter's to recto pages

 

Hi!

 

I
have a problem concerning the page breaks of <chapter> elements in
double-sided PDF output!

 

The
case is that I want <part>s, <toc>, <preface>, <index> and
<colophon> to break to the next recto page, while chapters and appendices
should only break to the next page (regardless if recto or verso).

 

First
I tried to modify the “force.page.count”- and
“initial.page.number”-templates as follows:

 

force.page.count(only changed content)::

<xsl:choose>

  
<xsl:when test="$element !=
'chapter'">auto</xsl:when>  

  
<xsl:when test="$double.sided !=
0">end-on-even</xsl:when>  

  
<xsl:otherwise>no-force</xsl:otherwise>

</xsl:choose>

 

initial.page.number(only changed content):

<xsl:when
test="$double.sided != 0">

       
<xsl:choose>

            
  <xsl:when test="$element =
'chapter'">auto</xsl:when>

…

 

Unfortunately this ended up in displaying
me a “half-double-sided” and “half-single-sided”
document. Furthermore, not every chapter wants to wrap to a verso page…

 

I also tried to add a custom
user-pagemaster:

 

<xsl:template
name="user.pagemasters">

   
<fo:page-sequence-master master-name="body-chapter">

     
<fo:repeatable-page-master-alternatives>

       
<fo:conditional-page-master-reference master-reference="blank"

                                             
blank-or-not-blank="blank"/>

 

    
   <fo:conditional-page-master-reference
master-reference="body-odd"

                                             
odd-or-even="odd"/>

                                                                         
  

       
<fo:conditional-page-master-reference
odd-or-even="even">                                   
                                 
  

         
<xsl:attribute name="master-reference">

           
<xsl:choose>

             
<xsl:when test="$double.sided != 0">body-even</xsl:when>

             
<xsl:otherwise>body-odd</xsl:otherwise>

           
</xsl:choose>

         
</xsl:attribute>

       
</fo:conditional-page-master-reference>

     
</fo:repeatable-page-master-alternatives>

   
</fo:page-sequence-master>

</xsl:template>

 

<xsl:template
name="select.user.pagemaster">

 
<xsl:param name="element"/>

 
<xsl:param name="pageclass"/>

 
<xsl:param name="default-pagemaster"/>

 

 
<xsl:choose>

   
<xsl:when test="$element = 'chapter'">

     
<xsl:value-of select="'body-chapter'"/>

   
</xsl:when>

   
<xsl:otherwise>

     
<xsl:value-of select="$default-pagemaster"/>

   
</xsl:otherwise>

 
</xsl:choose>

</xsl:template>

 

After that it works almost perfect –
almost. The double-sided output is fine but again not every chapter breaks to a
verso page. I sometimes have one blank page in front of a chapter and sometimes
not.

 

Can anyone help me?

 

Thanks in advance,

 

Mathias Schindler
