Transform EPUB to RTF via Java
On Premise Java API to Render EPUB to RTF without using any third party application
Converting EPUB to RTF is a simple two-step process. First, you need to render the EPUB file to DOC using Aspose.PDF for Java. This powerful PDF Processing API is part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for working with a variety of document formats. Once the EPUB file has been rendered to DOC, you can then use Aspose.Words for Java to convert the DOC to RTF. Aspose.Words for Java is a powerful Document Processing API that enables you to quickly and easily convert documents from one format to another.
The combination of Aspose.PDF for Java and Aspose.Words for Java makes it easy to convert EPUB to RTF. All you need to do is render the EPUB file to DOC using Aspose.PDF for Java, and then use Aspose.Words for Java to convert the DOC to RTF. With Aspose.Total for Java, you can easily and quickly convert EPUB to RTF in just two simple steps.
Java API to Convert EPUB to RTF
Conversion Requirements
You can easily use Aspose.Total for Java directly from a Maven based project and include Aspose.PDF for Java and Aspose.Words for Java in your pom.xml.
Alternatively, you can get a ZIP file from downloads .
| Document document = new Document("template.epub"); | |
| document.save("DocOutput.doc", SaveFormat.DOC); | |
| Document outputDocument = new com.aspose.words.Document("DocOutput.doc"); | |
| outputDocument.save("output.docm", SaveFormat.DOCM); |
Open Password Protected EPUB Document via Java
While converting EPUB to RTF, even if your document is password protected, you can still open it using PDF Manipulation API Aspose.PDF for Java . In order to open the encrypted file, you need to create a Document object and open the EPUB using the owner’s password.
| Document document = new Document("input.epub", "password"); | |
| document.save("DocOutput.doc", SaveFormat.DOC); |
Save RTF Document to a Database via Java
While saving your input document to RTF file format, you can also save your document to database instead of a file system. You may need to implement storing and retrieving Document objects to and from a database. This would be necessary if you were implementing any type of content management system. In order to save your RTF to database it is often necessary to serialize the document to obtain a byte array. This can be done using Aspose.Words for Java API. After getting your byte array, you can store it in the database using SQL statement.
public static void StoreToDatabase(Document doc, Connection mConnection) throws Exception {
// create an output stream which uses byte array to save data
ByteArrayOutputStream aout = new ByteArrayOutputStream();
// save the document to byte array
doc.save(aout, SaveFormat.RTF);
// get the byte array from output steam
// the byte array now contains the document
byte[] buffer = aout.toByteArray();
// get the filename from the document.
String fileName = doc.getOriginalFileName();
String filePath = fileName.replace("\\", "\\\\");
// create the SQL command.
String commandString = "INSERT INTO Documents (FileName, FileContent) VALUES('" + filePath + "', '" + buffer + "')";
Statement statement = mConnection.createStatement();
statement.executeUpdate(commandString);
}
