Problem converting a non-standard sized document to PDF

[gizwhu]

I am having problems converting a non-standard sized document to pdf. Below is the stacktrace. Any help is appreciated.

Code: Select all

Here is my test code:

Code: Select all

        String regex = null;
        PhysicalFonts.setRegex(regex);
       
        WordprocessingMLPackage wordMLPackage;
       
        InputStream is = new ByteArrayInputStream(document);
        ByteArrayOutputStream baos = null;
        try {
            wordMLPackage = WordprocessingMLPackage.load(is);
           
             wordMLPackage = wordMLPackage.createPackage(PageSizePaper.A5, false);           
                   
            FieldUpdater updater = new FieldUpdater(wordMLPackage);
            updater.update(true);
           
            Mapper fontMapper = new IdentityPlusMapper();
            wordMLPackage.setFontMapper(fontMapper);
           

           
            FOSettings foSettings = Docx4J.createFOSettings();
            foSettings.setWmlPackage(wordMLPackage);
           
            /*OutputStream os = new java.io.FileOutputStream("C:/test.pdf");
            Docx4J.toFO(foSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);
            os.close();*/
               
            baos = new ByteArrayOutputStream();
           
            Docx4J.toFO(foSettings, baos, Docx4J.FLAG_EXPORT_PREFER_XSL);
            byte[] pdf = baos.toByteArray();
           
            updater = null;
            foSettings = null;
            wordMLPackage = null;
           
            return pdf;
        } catch (Docx4JException e) {
            e.printStackTrace();
            LOG.error(e.getMessage(), e);
        }

To understand what is happening, you should enable saving the intermediate .FO document, then inspect the fo:flow

Thanks for your quick reply. How do I enable this?

Something like foSettings.setFoDumpFile(new java.io.File(inputfilepath + ".fo"));

or foSettings.setApacheFopMime(FOSettings.INTERNAL_FO_MIME) to get FO instead of PDF:

Code: Select all

      // Document format:
      // The default implementation of the FORenderer that uses Apache Fop will output
      // a PDF document if nothing is passed via
      // foSettings.setApacheFopMime(apacheFopMime)
      // apacheFopMime can be any of the output formats defined in org.apache.fop.apps.MimeConstants eg org.apache.fop.apps.MimeConstants.MIME_FOP_IF or
      // FOSettings.INTERNAL_FO_MIME if you want the fo document as the result.
      //foSettings.setApacheFopMime(FOSettings.INTERNAL_FO_MIME);
