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

Hi,

It looks like this line in the 'force.page.count' 
template is the problem:

 

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

 

Shouldn't that be $element = 'chapter'  
?  If you change it, I get each chapter starting on the next 
page.

And here’s a

In the first 2 
  chapter’s everything is fine(as you can see in the picture they only take one 
  site each). But in the following chapter’s there’s always a blank page 
  (infront?) after every chapter.

  
I hope you can see 
  my problem now.

Hi 
  Mathias,

  

  
Just reviewing the 
  XSL, I cannot see why this would not work.  Can you provide a short XML 
  input file that illustrates the problem?

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="''"/>

    'chapter'">auto</xsl:when>  

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

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

    
    
    </xsl:choose>

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?

      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,
