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
Get Started with Java File Manipulation APIs
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 .
// load EPUB file with an instance of Document class
Document document = new Document("template.epub");
// save EPUB as a DOC
document.save("DocOutput.doc", SaveFormat.DOC);
// load DOC with an instance of Document
Document outputDocument = new com.aspose.words.Document("DocOutput.doc");
// call save method while passing SaveFormat.RTF
outputDocument.save("output.rtf", SaveFormat.RTF);
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");
// save EPUB as a DOC
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);
}

What is EPUB File Format?
An EPUB file, also known as an Open eBook File, is a standardized format developed by the International Digital Publishing Forum (IDPF). It is based on XML (eXtensible Markup Language) and XHTML (eXtensible Hypertext Markup Language). EPUB files are designed for reading digital books and publications on various electronic devices such as e-readers, tablets, and smartphones.
EPUB files consist of three main components. The first component is the spine, which contains the main text of the book and defines the order in which the pages should be read. It provides the structural framework for the content.
The second component is the manifest, which serves as a catalog of all the files that make up the EPUB book. This includes the spine, cover image, table of contents, and any additional content. The manifest ensures that all the necessary files are properly linked and organized within the EPUB package.
The third component is the container, which stores the EPUB files in a compressed format. The container helps reduce file size and enables efficient distribution and storage of EPUB books.
EPUB files can be created using various software programs such as Adobe InDesign, Sigil, and Calibre. These tools provide authors and publishers with the ability to create, edit, and format EPUB books according to the specifications set by the IDPF. With EPUB being an open and widely adopted standard, readers can enjoy a seamless reading experience across different devices and platforms.
What is RTF File Format?
The RTF (Rich Text Format) file format is a versatile and widely supported file format for storing text documents with formatting. It was developed by Microsoft in the late 1980s as a cross-platform format that could be easily exchanged between different word processing applications.
RTF files are typically saved with the .rtf file extension and can be opened and edited by various text editors and word processing software, including Microsoft Word, Google Docs, and LibreOffice. The format allows for the inclusion of various formatting elements, such as font styles, sizes, colors, paragraphs, tables, and images.
One of the key advantages of RTF is its platform independence, which means that an RTF file created on one operating system can be opened and rendered correctly on another without losing formatting. This makes it a preferred choice for document exchange and collaboration.
RTF files use a plain-text formatting syntax, which means that the files are human-readable and can be modified with a text editor if needed. However, RTF files can be quite large in size compared to other formats like plain text or Markdown, as they store formatting information explicitly.
While RTF is primarily used for text documents, it can also support the embedding of other types of files, such as images and objects, within the document. This allows for the creation of more complex and visually appealing documents.
