Description

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//imagedata[@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:
