Transform EPUB to FLATOPC via Java
On Premise Java API to Render EPUB to FLATOPC without using any third party application
Converting EPUB to FLATOPC is a simple two-step process that can be done using the powerful Document Processing API Aspose.Words for Java. Aspose.Words for Java is part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for working with documents.
The first step is to render the EPUB file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF manipulation API that can be used to convert EPUB to DOC. It provides a wide range of features, including the ability to render EPUB to DOC.
Once the EPUB file has been rendered to DOC, the second step is to use Aspose.Words for Java to convert the DOC to FLATOPC. Aspose.Words for Java is a powerful document processing API that can be used to convert DOC to FLATOPC. It provides a wide range of features, including the ability to convert DOC to FLATOPC.
By using Aspose.Total for Java, you can easily convert EPUB to FLATOPC in just two simple steps. First, you render the EPUB file to DOC using Aspose.PDF for Java. Then, you use Aspose.Words for Java to convert the DOC to FLATOPC. With Aspose.Total for Java, you can quickly and easily convert EPUB to FLATOPC.
Java API to Convert EPUB to FLATOPC
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.FLAT_OPC
outputDocument.save("output.flat_opc", SaveFormat.FLAT_OPC);
Open Password Protected EPUB Document via Java
While converting EPUB to FLATOPC, 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 FLATOPC Document to a Database via Java
While saving your input document to FLATOPC 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 FLATOPC 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.FLAT_OPC);
// 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 FLATOPC File Format?
The FLATOPC format is an XML-based file format specifically used by Microsoft Word 2003 and later versions. It serves as a compressed variant of the WordprocessingML format, aiming to improve efficiency in terms of storage and transmission. By utilizing compression techniques, FLATOPC files are designed to occupy less space while maintaining the essential content of the document.
FLATOPC format finds its application not only in Microsoft Word but also in other related software. For instance, Microsoft Office Word Viewer, a program dedicated to viewing Word documents, supports the FLATOPC format. Additionally, Microsoft Office Word for the web, the online version of Microsoft Word, also employs the FLATOPC format for document storage and processing.
The XML-based nature of the FLATOPC format enables structured representation of the document’s content, formatting, and other relevant information. It provides a standardized and machine-readable format that allows for easy parsing and manipulation of Word documents.
