Why to Convert
If you are a C++ developer looking to add the ability to convert EPUB to PPSX files inside your C++ applications, then you will need to use a reliable and efficient solution. This is because EPUB and PPSX are two different file formats and require different APIs to convert between them.
How Aspose.Total Helps for EPUB to PPSX Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to create, manipulate, and convert various file formats. It includes two APIs that are specifically designed to convert EPUB to PPSX files. The first is Aspose.PDF for C++, which can be used to export EPUB to PPTX. The second is Aspose.Slides for C++, which can be used to convert PPTX to PPSX. Both of these APIs are included in the Aspose.Total for C++ package, making it easy to access and use them.
Using Aspose.Total for C++, developers can easily integrate EPUB to PPSX conversion into their C++ applications in just two simple steps. First, they can use Aspose.PDF for C++ to export EPUB to PPTX. Then, they can use Aspose.Slides for C++ to convert PPTX to PPSX. This makes it easy to add the ability to convert EPUB to PPSX files into C++ applications, without having to write any additional code.
Aspose.Total for C++ is a powerful and reliable solution for developers who need to add the ability to convert EPUB to PPSX files into their C++ applications. It includes two APIs that are specifically designed for this purpose, making it easy to integrate EPUB to PPSX conversion into C++ applications in just two simple steps.
C++ API to Export EPUB to PPSX
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 Ppsx format prs->Save(u"output.ppsx", Aspose::Slides::Export::SaveFormat::Ppsx);
Change Password of EPUB Document via C++
In the process of rendering EPUB to PPSX, 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 PPSX File via C++
After converting EPUB to PPSX, 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 PPSX file
// instantiate a Presentation object that represents a PPSX file auto pres = System::MakeObject<Presentation>("output.ppsx"); // 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.ppsx", SaveFormat::Ppsx);

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 PPSX File Format?
The PPXS file format is a file extension used by Microsoft PowerPoint to save presentations in a compressed format. It is an extension of the PPTX file format, which is the default file format for PowerPoint presentations. The “S” in PPXS stands for “compressed”, indicating that the file has undergone compression to reduce its size.
The purpose of the PPXS format is to create smaller file sizes for PowerPoint presentations, making them easier to share, transfer, and store. The compression algorithm used in PPXS files helps to reduce the overall file size while maintaining the content and formatting of the presentation.
PPXS files can be created and edited using Microsoft PowerPoint or other software that supports the PowerPoint file format. They contain various multimedia elements such as text, images, videos, audio, and animations, just like regular PowerPoint presentations.
When opening a PPXS file, PowerPoint decompresses the file to restore it to its original PPTX format, allowing users to view and edit the presentation as they would with any other PowerPoint file.
The use of the PPXS format can be beneficial when working with large presentations or when there is a need to optimize file sizes for sharing or storage purposes. However, it’s worth noting that decompressing the PPXS file to its original PPTX format may require additional processing time.
