Once the EPUB is converted to PPTX, you can use Aspose.Slides for C++ to convert PPTX to OTP. This API provides a comprehensive set of features for creating, editing, and converting presentations.
By using Aspose.Total for C++, developers can easily integrate EPUB to OTP conversion feature into their C++ applications. It provides a simple and efficient way to convert EPUB to OTP, allowing developers to create interactive documents that can be used in a variety of applications.
C++ API to Export EPUB to OTP
- Open EPUB file using Document class reference
- Convert EPUB to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to OTP format using
Save
member function and set
Otpas SaveFormat
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 Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load EPUB file with an instance of Document class
auto doc = MakeObject<Document>(u"template.epub");
// save EPUB as PPTX format
doc->Save(u"PptxOutput.pptx", SaveFormat::Pptx);
// instantiate a Presentation object that represents a PPTX file
SharedPtr<Presentation> prs = MakeObject<Presentation>(u"PptxOutput.pptx");
// save the presentation as Otp format
prs->Save(u"output.otp", Aspose::Slides::Export::SaveFormat::Otp);
Change Password of EPUB Document via C++
In the process of rendering EPUB to OTP, 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");
Add Images From Web in OTP File via C++
After converting EPUB to OTP, you can also add images from web to your output document. Aspose.Slides for C++ supports operations with images in these popular formats: JPEG, PNG, BMP, GIF, and others. You can add one or several images on your computer onto a slide in a presentation. This sample code in C++ shows you how to add an image to a OTP file
// instantiate a Presentation object that represents a OTP file
auto pres = System::MakeObject<Presentation>("output.otp");
// get slide
auto slide = pres->get_Slides()->idx_get(0);
// initialize Web Client
auto webClient = System::MakeObject<WebClient>();
// get image data
auto imageData = webClient->DownloadData(System::MakeObject<Uri>(u"[REPLACE WITH URL]"));
// add image
auto image = pres->get_Images()->AddImage(imageData);
// add picture frame
slide->get_Shapes()->AddPictureFrame(ShapeType::Rectangle, 10.0f, 10.0f, 100.0f, 100.0f, image);
// save updated file
pres->Save(u"updated.otp", SaveFormat::Otp);

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 OTP File Format?
The OpenDocument Standard Format (ODF) serves as an XML-based file format for representing various electronic documents, including spreadsheets, charts, presentations, and word processing documents. The format is standardized by the Organization for the Advancement of Structured Information Standards (OASIS) and was initially adopted by ISO/IEC JTC1 SC34 in 2005. One of the key advantages of ODF is that it is an open format, meaning it is not restricted by copyright or patent limitations.
ODF is built upon the XML schema derived from the OpenOffice.org office suite and employs the Zip compression algorithm. Its design objective is to be platform-independent, enabling support across a wide range of applications and operating systems.
The ODF specification defines three main document types: text documents, spreadsheets, and presentations. Each document type corresponds to a specific XML schema. These schemas are designed to be extensible, allowing for the addition of application-specific features.
ODF documents have the capability to be encrypted and signed using the XML Encryption and XML Signature standards. This provides security and integrity options for sensitive or important documents.
Numerous office applications support the OpenDocument Format, including Apache OpenOffice, LibreOffice, IBM Lotus Symphony, and even Microsoft Office. This broad support ensures compatibility and facilitates the exchange and collaboration of documents across different software platforms.
