Why to Convert
EPUB is a popular file format for e-books, which is widely used for digital publications. It is an open standard format that is used to create and publish digital books. However, there are certain limitations with EPUB format, such as lack of support for complex formatting, limited support for multimedia, and lack of support for interactive elements. Therefore, many publishers and authors prefer to convert EPUB to FLATOPC format, which is a more advanced and feature-rich format.
How Aspose.Total helps for epub to flatopc conversion
Aspose.Total for C++ is a comprehensive suite of file format automation libraries that enables C++ developers to easily convert EPUB to FLATOPC in two simple steps. Firstly, you can use Aspose.PDF for C++ API to convert EPUB file format to DOC. Secondly, by using advanced Word Document Processing API Aspose.Words for C++, you can export DOC to FLATOPC. Aspose.Total for C++ is a powerful and reliable solution for converting EPUB to FLATOPC, as it provides a comprehensive set of APIs that are easy to use and highly efficient. Moreover, it is a cost-effective solution that can be used to quickly and easily convert EPUB to FLATOPC.
C++ API to Render EPUB to FLATOPC
Get Started with C++ File Automation APIs
Install from command line as
nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load EPUB file with an instance of Document class reference auto doc = MakeObject<Document>(u"sourceFile.epub"); // save EPUB as a DOC doc->Save(u"DocOutput.doc", SaveFormat::Doc); // load DOC with an instance of Document System::SharedPtr<Document> wordDoc = System::MakeObject<Document>(u"DocOutput.doc"); // save document as FlatOpc wordDoc->Save(u"output.FlatOpc");
Change Password of EPUB Document via C++
In the process of rendering EPUB to FLATOPC, you can open a password protected EPUB and also change its password. In order to change the password of a EPUB file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing EPUB Document auto doc = MakeObject<Document>(L"input.epub", L"owner"); // change password of EPUB Document doc->ChangePasswords(L"owner", L"newuser", L"newuser"); // save the document doc->Save(L"output.Doc");
Restrict FLATOPC File Editing via C++
You can also restrict FLATOPC file editing using using Aspose.Words for C++ API. Sometimes you may need to limit the ability to edit a document and only allow certain actions with it. API enables you to control the way you restrict the content using the ProtectionType enumeration parameter. The following code example demonstrates how to restrict editing in a document so only editing in form fields is possible.
// load Doc with an instance of Document auto doc = System::MakeObject<Document>("input.doc"); // document protection only works when document protection is turned and only editing in form fields is allowed. doc->Protect(ProtectionType::AllowOnlyFormFields, u"password"); // save the protected document. doc->Save(u"Protected.FlatOpc");

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.
