Re: [docbook-apps] imageobject in task leads to strange result in pdf

Hi Lars,

The task template apparently applies the  
attribute-set named 'formal.object.properties' to task, and that attribute-set 
has a keep-together.within-column="always" attribute.  With your three tall 
images that prevent the task from fitting on one page, FOP fails to handle such 
a large keep. 

 

The solution for this task is to add a processing 
instruction:

 

<task>

<?dbfo 
 keep-together="auto"?>

 

If you want to globally turn off the keep for all 
tasks, then your customization layer should have:

 

<xsl:attribute-set 
name="formal.object.properties">

  <xsl:attribute 
name="keep-together.within-column">

    <xsl:choose>

      <xsl:when 
test="self::task">auto</xsl:when>

      
<xsl:othewise>always</xsl:otherwise>

    </xsl:choose>

  </xsl:attribute>

</xsl:attribute-set>

 

Personally I think task should have its own 
attribute-set to make such customizations easier for tasks.

Subject: [docbook-apps] imageobject in 
  task leads to strange result in pdf

  

Hello,
  

  
I'm trying to utilize the <task> element. But if I add imageobjects 
  the pdf result looks broken. 

  

  
The example document I use is listed below and the rendering result is 
  attached.

  

  
Any advice what I'm doing wrong? The input document validates in 
  Eclipse. 

  

  
Best regards, Lars
