Sorry for replying to a thread on the wrong list.

To recap the discussion, there was a posting on the DocBook list 
saying that FOP was not able to process images correctly with the 
DocBook XSL style sheets. 

I tried to investigate the problem and posted a debugging aid 
yesterday. Unfortunately, I missed some important details like 
setting my CLASSPATH to use norm's extensions and changing 
my customization layer to include the use.extensions parameter. 

After making those changes, I still cannot process an XML file. 
FOP uses the extensions correctly. (There's not a problem with the 
fop.extensions parameter in the style sheets). However, FOP 
blows stack when it reaches an image in my document.

If I am wrong, please correct me. I believe the problem is with FOP, 
not norm's style sheets. In particular, I believe it has to do with 
FOP's ability to scale images.


CLASSPATH=$CLASSPATH::$TEMPLATE_HOME/extensions/xal
an2.jar  

[ customization layer ]

<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version='1.0'
                xmlns="http://www.w3.org/TR/xhtml1/transitional">

<xsl:import href="docbook.xsl"/>

<!-- Use extensions -->
<xsl:param name="use.extensions" select="'1'"/>

<!-- Use FOP extensions -->
<xsl:param name="fop.extensions" select="1"/>

</xsl:stylesheet>

[ graphics.xsl aid ]

<xsl:template name="process.image">
  <xsl:if test="$fop.extensions != 0">
    <xsl:message terminate="no">
      <xsl:text>Parameter is set to use FOP extensions</xsl:text>
    </xsl:message>
  </xsl:if>
