Render EPUB to ODP within C++ Applications
Convert EPUB to ODP within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
As a C++ developer, you may need to integrate EPUB to ODP conversion feature inside your C++ applications. This is because EPUB is a popular format for e-books, while ODP is a popular format for presentations. Converting from one format to another can help you make the most out of your content.
How Aspose.Total Helps for EPUB to ODP Conversion
Aspose.Total for C++ is a comprehensive package of APIs that can help you with the conversion of EPUB to ODP. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++. With Aspose.PDF for C++, you can export EPUB to PPTX. Then, with Aspose.Slides for C++, you can convert PPTX to ODP. This way, you can easily convert EPUB to ODP in two simple steps.
C++ API to Export EPUB to ODP
- 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 ODP format using
Save
member function and set
Odpas 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 Odp format
prs->Save(u"output.odp", Aspose::Slides::Export::SaveFormat::Odp);
Change Password of EPUB Document via C++
In the process of rendering EPUB to ODP, 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 ODP File via C++
After converting EPUB to ODP, 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 ODP file
// instantiate a Presentation object that represents a ODP file
auto pres = System::MakeObject<Presentation>("output.odp");
// 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.odp", SaveFormat::Odp);

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 ODP File Format?
ODP is a file format used for storing presentation slides in the Open Document Format (ODF). ODP stands for Open Document Presentation. It is the default file format for presentation software applications such as LibreOffice Impress, OpenOffice Impress, and Apache OpenOffice.
ODP files are based on XML, which is a markup language used for organizing and structuring data. They are designed to be an open and interoperable format, allowing users to create, edit, and share presentation slides across different software applications and platforms.
The ODP format supports a wide range of features and elements commonly used in presentations. It includes support for slide layouts, text formatting, images, charts, tables, transitions, animations, and multimedia elements such as audio and video.
One of the advantages of the ODP format is its compatibility with different presentation software. Users can create an ODP presentation in one application and open it in another without losing formatting or content. This facilitates collaboration and allows for seamless sharing and editing of presentations among users.
ODP files can be easily converted to other popular presentation formats, such as Microsoft PowerPoint’s PPTX format or PDF, for broader accessibility and sharing purposes. Additionally, the ODP format promotes long-term document preservation and accessibility, ensuring that presentations can be accessed and displayed accurately over time.
