Why to Convert
As a C++ developer, you may need to integrate EPUB to PPSM conversion feature inside your C++ applications. EPUB is a popular format for e-books, while PPSM is a Microsoft PowerPoint Show format. Converting EPUB to PPSM allows you to view the content of the e-book in a presentation format.
How Aspose.Total Helps for EPUB to PPSM Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to create, manipulate, convert, and render documents in various formats. It includes APIs for PDF, Slides, and Words. With Aspose.Total for C++, you can easily export EPUB to PPTX and then convert PPTX to PPSM.
To export EPUB to PPTX, you can use Aspose.PDF for C++. It is a powerful PDF manipulation API that enables developers to create, read, edit, and convert PDF documents. It also supports conversion of PDF documents to other popular formats, including PPTX.
To convert PPTX to PPSM, you can use Aspose.Slides for C++. It is a powerful presentation manipulation API that enables developers to create, read, edit, and convert presentations. It also supports conversion of presentations to other popular formats, including PPSM.
Both APIs come under Aspose.Total for C++ package. With Aspose.Total for C++, you can easily export EPUB to PPTX and then convert PPTX to PPSM in two simple steps.
C++ API to Export EPUB to PPSM
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 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 Ppsm format prs->Save(u"output.ppsm", Aspose::Slides::Export::SaveFormat::Ppsm);
Change Password of EPUB Document via C++
In the process of rendering EPUB to PPSM, 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 PPSM File via C++
After converting EPUB to PPSM, 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 PPSM file
// instantiate a Presentation object that represents a PPSM file auto pres = System::MakeObject<Presentation>("output.ppsm"); // 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.ppsm", SaveFormat::Ppsm);

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 PPSM File Format?
The PPSM file format is an extension used by Microsoft PowerPoint to save presentations with embedded macros. It is an evolution of the PPSX file format, which is commonly used for PowerPoint slideshow presentations. The “M” in PPSM stands for “macro-enabled”, indicating that the file supports the execution of macros within the presentation.
PPSM files allow for interactive and dynamic content in PowerPoint presentations through the use of macros, which are sets of instructions or commands that automate tasks or add functionality. Macros can be created using Visual Basic for Applications (VBA) and provide advanced capabilities such as interactive buttons, automated actions, and custom functions.
When a PPSM file is opened, PowerPoint enables the execution of macros, allowing the presentation to respond to user interactions or perform predefined actions. This enables the creation of interactive slideshows and enhances the overall user experience.
The PPSM format is particularly useful for creating self-running presentations, kiosk displays, or interactive training modules. By incorporating macros, presenters can automate processes, trigger specific actions, or customize the behavior of the presentation based on user input.
It’s important to note that due to the potential security risks associated with macros, some organizations may have security settings in place that restrict the execution of macros in PowerPoint files. Therefore, when sharing PPSM files, it’s essential to ensure that recipients are aware of the macro functionality and have appropriate security settings enabled.
