jOpenDocument:尝试从ODS生成PDF时出现问题

Question

我有一个.ods文件，并希望使用jOpenDocument (Java)将其导出为.ods。

我使用以下代码：

                         // load the ODS file
        final OpenDocument filledCertificate = new OpenDocument();
        filledCertificate.loadFrom("filledCertificate.ods");

        // Open the PDF document
        Document document = new Document(PageSize.A4);
        File outFile = new File("certificate.pdf");

        PdfDocument pdf = new PdfDocument();

        document.addDocListener(pdf);
        System.out.println("test");
        FileOutputStream fileOutputStream = new FileOutputStream(outFile);
        PdfWriter writer = PdfWriter.getInstance(pdf, fileOutputStream);
        pdf.addWriter(writer);

        document.open();

        // Create a template and a Graphics2D object 
        Rectangle pageSize = document.getPageSize();
        int w = (int) (pageSize.getWidth() * 0.9);
        int h = (int) (pageSize.getHeight() * 0.95);
        PdfContentByte cb = writer.getDirectContent();
        PdfTemplate tp = cb.createTemplate(w, h);
        System.out.println("test 2");
        Graphics2D g2 = tp.createPrinterGraphics(w, h, null);
        // If you want to prevent copy/paste, you can use
        // g2 = tp.createGraphicsShapes(w, h, true, 0.9f);

        tp.setWidth(w);
        tp.setHeight(h);
        System.out.println("test 3");

        // Configure the renderer
        ODTRenderer renderer = new ODTRenderer(filledCertificate);

        System.out.println("test 3.1");
        renderer.setIgnoreMargins(true);
        System.out.println("test 3.2");
        renderer.setPaintMaxResolution(true);
        System.out.println("test 4");                      
        // Scale the renderer to fit width
        renderer.setResizeFactor(renderer.getPrintWidth() / w);
        // Render
        renderer.paintComponent(g2);
        g2.dispose();

        // Add our spreadsheet in the middle of the page
        float offsetX = (pageSize.getWidth() - w) / 2;
        float offsetY = (pageSize.getHeight() - h) / 2;
        cb.addTemplate(tp, offsetX, offsetY);
        System.out.println("test 5");
        // Close the PDF document
        document.close();

运行时，控制台显示如下：

StylePageLayoutProperties: Assuming Page Format A4: Width:  21.0cm
StylePageLayoutProperties: Assuming Page Format A4: Height: 29.7cm
StylePageLayoutProperties: Assuming Page Format A4: Width:  21.0cm

我真的不知道我可以在这里修改哪种风格？实例化只需要OpenDocument作为参数。

异常处理已经包含在内(不是代码段的一部分)。

提前感谢您的帮助！

我可以自己解决这个问题:我只是使用了一个旧版本的jOpenDocument (1.3)。
