In brief, it expects a raw URL like image.gif in the src attribute of fo:external-graphic rather than url(image.gif). If you add the following templates to your driver stylesheet it should fix the problem: <xsl:template name="process.image"> <!-- When this template is called, the current node should be --> <!-- a graphic, inlinegraphic, imagedata, or videodata. All --> <!-- those elements have the same set of attributes, so we can --> <!-- handle them all in one place. --> <xsl:variable name="input-filename"> <xsl:choose> <xsl:when test="@entityref"> <xsl:value-of select="unparsed-entity-uri(@entityref)"/> </xsl:when> <xsl:when test="@fileref"> <!-- FIXME: is this right? What if @fileref is a relative --> <!-- URI? What if @fileref contains backslashes? --> <xsl:text>file:</xsl:text> <xsl:value-of select="@fileref"/> </xsl:when> <xsl:otherwise> <xsl:message> <xsl:text>Expected @entityref or @fileref on </xsl:text> <xsl:value-of select="name(.)"/> </xsl:message> </xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:variable name="fileext"> <xsl:call-template name="filename-extension"> <xsl:with-param name="filename" select="$input-filename"/> </xsl:call-template> </xsl:variable> <xsl:variable name="filename"> <xsl:choose> <xsl:when test="$fileext != ''"> <xsl:value-of select="$input-filename"/> </xsl:when> <xsl:when test="$graphic.default.extension != ''"> <xsl:value-of select="$input-filename"/> <xsl:text>.</xsl:text> <xsl:value-of select="$graphic.default.extension"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="$input-filename"/> </xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:variable name="scale"> <xsl:choose> <xsl:when test="@scale"><xsl:value-of select="@scale"/>%</xsl:when> <xsl:otherwise>auto</xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:variable name="width"> <xsl:choose> <xsl:when test="@width"> <xsl:call-template name="length-spec"> <xsl:with-param name="length" select="@width"/> <xsl:with-param name="default.units" select="$default.units"/> </xsl:call-template> </xsl:when> <xsl:otherwise>auto</xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:variable name="height"> <xsl:choose> <xsl:when test="@depth"> <xsl:call-template name="length-spec"> <xsl:with-param name="length" select="@depth"/> <xsl:with-param name="default.units" select="$default.units"/> </xsl:call-template> </xsl:when> <xsl:otherwise>auto</xsl:otherwise> </xsl:choose> </xsl:variable> <!-- Scaling seems to require calculating an absolute width and height from a scale factor and the intrinsic width and height (possibly with contributions from the specified width and height).
