Render EPUB to PPS within C++ Applications
Convert EPUB to PPS within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer, you may need to integrate EPUB to PPS conversion feature inside your C++ applications. EPUB is a popular format for e-books, while PPS is a presentation format used by Microsoft PowerPoint. Converting EPUB to PPS allows you to create presentations from e-books, which can be used for educational or business purposes.
How Aspose.Total Helps for EPUB to PPS Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to create, manipulate, and convert various file formats. It includes two APIs that can be used to convert EPUB to PPS: Aspose.PDF for C++ and Aspose.Slides for C++.
Using Aspose.PDF for C++, you can export EPUB to PPTX, which is a presentation format supported by Microsoft PowerPoint. Then, using Aspose.Slides for C++, you can convert PPTX to PPS. This way, you can easily convert EPUB to PPS without any hassle.
Aspose.Total for C++ is a great choice for developers who need to integrate EPUB to PPS conversion feature in their C++ applications. It is a comprehensive suite of APIs that can be used to create, manipulate, and convert various file formats. Moreover, it is easy to use and provides great performance.
C++ API to Export EPUB to PPS
- 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 PPS format using
Save
member function and set
Ppsas 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 Pps format
prs->Save(u"output.pps", Aspose::Slides::Export::SaveFormat::Pps);
Change Password of EPUB Document via C++
In the process of rendering EPUB to PPS, 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 PPS File via C++
After converting EPUB to PPS, 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 PPS file
// instantiate a Presentation object that represents a PPS file
auto pres = System::MakeObject<Presentation>("output.pps");
// 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.pps", SaveFormat::Pps);

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 PPS File Format?
The PPS file format is an extension used by Microsoft PowerPoint to save presentations specifically designed for slideshow purposes. It stands for “PowerPoint Slide Show” and is closely related to the PPT (PowerPoint Presentation) format. PPS files contain a collection of slides, each with its own content, layout, and formatting.
Unlike PPT files, which open in the PowerPoint editor, PPS files are intended to be opened directly in slideshow mode. When a PPS file is opened, it launches the presentation in full-screen mode, immediately displaying the slides in the order they were created. This allows for a seamless and uninterrupted presentation experience without the need for manual navigation.
PPS files are commonly used for sharing presentations with others who only need to view the slides rather than edit them. By saving a presentation as a PPS file, you ensure that recipients can open and view the presentation as intended without accidentally modifying the content. This makes it a convenient format for distributing slideshows for meetings, conferences, or self-running presentations.
The PPS format retains all the visual elements, animations, transitions, and multimedia content included in the original PowerPoint presentation. It provides a convenient way to deliver polished and professional-looking slideshows that maintain their intended design and effects.
To open and view PPS files, recipients typically need a compatible software application such as Microsoft PowerPoint, PowerPoint Viewer, or other presentation software capable of reading PPS files. These applications allow users to enjoy the full presentation experience without the need for authoring or editing capabilities.
