           Summary: FOP cannot handle background images in <fo:block> when
                    creating RTF.
           Product: Fop
           Version: 0.95
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: rtf
        AssignedTo: fop-dev@xmlgraphics.apache.org
        ReportedBy: tech_...@yahoo.com


Using XSLT + Docbook stylesheets + FOP 0.95:

I have a document (in A5 format) that can be flawlessly compiled in PDF format,
but fails in RTF. It seems that FOP cannot handle background images in
<fo:block> elements when creating an RTF file. The following API in my
print.xsl has caused this problem:


<xsl:param name="chap.label.path"
 
select="normalize-space(//bookinfo//imageda...@role='chap_label']/@fileref)"/>

<xsl:attribute-set name="chap.label.properties">
  ...
  <xsl:attribute name="background-image">
    <xsl:call-template name="fo-external-image">
      <xsl:with-param name="filename" select="$chap.label.path"/>
    </xsl:call-template>
  </xsl:attribute>
  <xsl:attribute name="background-attachment">fixed</xsl:attribute>
  <xsl:attribute name="background-repeat">no-repeat</xsl:attribute>
</xsl:attribute-set>

FOP fails to place the chapter number on top of a background
icon. As I said, in PDF it works fine.

When compiling RTF, I get the following error message:
