Convert Document to PDF

To convert a document to PDF simply invoke the Document.save() method and specify a file name with the .pdf extension.

Java

// Load the document from disk. Document doc = new Document(dataDir + "document.doc"); doc.save(dataDir + "Aspose_DocToPDF.pdf",SaveFormat.PDF); //Save the document in PDF format. doc.save(dataDir + "html/Aspose_DocToHTML.html",SaveFormat.HTML); //Save the document in HTML format. doc.save(dataDir + "Aspose_DocToTxt.txt",SaveFormat.TEXT); //Save the document in TXT format. doc.save(dataDir + "Aspose_DocToJPG.jpg",SaveFormat.JPEG); //Save the document in JPEG format. 

Docx4j - Convert Document to PDF

The following code example shows how documents can be converted to PDF format using docx4j library.

Java

// The path to the documents directory. static String dataDir = Utils.getDataDir(Docx4jConvertToPDF.class); static  inputfilepath = dataDir + "document.docx"; saveFO = true; > // For demo/debugging purposes, save the intermediate XSL FO // Don't do this in production! static boolean saveFO; public static void main(String[] args) throws Exception  try  getInputFilePath(args); > catch (IllegalArgumentException e)  > // Font regex (optional) // Set regex if you want to restrict to some defined subset of fonts // Here we have to do this before calling createContent, // since that discovers fonts String regex = null; // Windows: // String // regex=".*(calibri|camb|cour|arial|symb|times|Times|zapf).*"; //regex=".*(calibri|camb|cour|arial|times|comic|georgia|impact|LSANS|pala|tahoma|trebuc|verdana|symbol|webdings|wingding).*"; // Mac // String // regex=".*(Courier New|Arial|Times New Roman|Comic Sans|Georgia|Impact|Lucida Console|Lucida Sans Unicode|Palatino Linotype|Tahoma|Trebuchet|Verdana|Symbol|Webdings|Wingdings|MS Sans Serif|MS Serif).*"; PhysicalFonts.setRegex(regex); // Document loading (required) WordprocessingMLPackage wordMLPackage; if (inputfilepath==null)  // Create a docx System.out.println("No input path passed, creating dummy document"); wordMLPackage = WordprocessingMLPackage.createPackage(); SampleDocument.createContent(wordMLPackage.getMainDocumentPart()); > else  // Load .docx or Flat OPC .xml System.out.println("Loading file from " + inputfilepath); wordMLPackage = WordprocessingMLPackage.load(new java.io.File(inputfilepath)); > // Refresh the values of `DOCPROPERTY` fields FieldUpdater updater = new FieldUpdater(wordMLPackage); updater.update(true); // Set up font mapper (optional) Mapper fontMapper = new IdentityPlusMapper(); wordMLPackage.setFontMapper(fontMapper); // .. example of mapping font Times New Roman which doesn't have certain Arabic glyphs // eg Glyph "ي" (0x64a, afii57450) not available in font "TimesNewRomanPS-ItalicMT". // eg Glyph "ج" (0x62c, afii57420) not available in font "TimesNewRomanPS-ItalicMT". // to a font which does PhysicalFont font = PhysicalFonts.get("Arial Unicode MS"); // make sure this is in your regex (if any). // if (font!=null)  // fontMapper.put("Times New Roman", font); // fontMapper.put("Arial", font); // > // fontMapper.put("Libian SC Regular", PhysicalFonts.get("SimSun")); // FO exporter setup (required) // .. the `FOSettings` object FOSettings foSettings = Docx4J.createFOSettings(); if (saveFO)  foSettings.setFoDumpFile(new java.io.File(inputfilepath + ".fo")); > foSettings.setWmlPackage(wordMLPackage); // 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); // exporter writes to an OutputStream.
