使用hwpf apache poi将word转换为FO

Question

如何使用hwpf.converter.WordToFo类将.doc文件转换为FO？我已经尝试搜索，但我只能得到一个单词到html的转换。我还在apache-poi站点上阅读了WordToFO手册，但无法获得它。

Convert Word to HTML with Apache POI

我尝试使用以下代码将.doc转换为.fo，但在使用apache-fop将.fo文件转换为.png后，我无法获得word文件中存在的图像。

        HWPFDocumentCore wordDocument = WordToFoUtils.loadDoc(new FileInputStream("D:\\Magna.doc"));
        System.out.println("reached 2");
        WordToFoConverter wordToFoConverter = new WordToFoConverter(
                DocumentBuilderFactory.newInstance().newDocumentBuilder()
                        .newDocument());
        System.out.println("reached 3");
        wordToFoConverter.processDocument(wordDocument);
        org.w3c.dom.Document htmlDocument = wordToFoConverter.getDocument();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        DOMSource domSource = new DOMSource((Node) htmlDocument);
        StreamResult streamResult = new StreamResult(out);
        System.out.println("reached 4");

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer serializer;
        try {
            serializer = tf.newTransformer();
             serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
                serializer.setOutputProperty(OutputKeys.INDENT, "yes");
                //serializer.setOutputProperty(OutputKeys.METHOD, "xml-fo");
                serializer.transform(domSource, streamResult);
                out.close();

                String result = new String(out.toByteArray());
                System.out.println(result);

        } catch (TransformerConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

}
}

    HWPFDocument hwpfDocument = new HWPFDocument(POIDataSamples.getDocumentInstance().openResourceAsStream(sampleFileName));

    WordToFoConverter wordToFoConverter = new WordToFoConverter(XMLHelper.getDocumentBuilderFactory().newDocumentBuilder().newDocument());
    wordToFoConverter.processDocument(hwpfDocument);

    StringWriter stringWriter = new StringWriter();

    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.transform(new DOMSource(wordToFoConverter.getDocument()), new StreamResult(stringWriter));

    String result = stringWriter.toString();
    return result;
