Why to Convert
As a C++ developer, you may need to integrate the feature of EPUB to POTM conversion in your applications. This conversion is necessary to make the content of EPUB files compatible with the POTM format.
How Aspose.Total Helps for EPUB to POTM Conversion
Aspose.Total for C++ is a comprehensive package of APIs that helps developers to easily integrate features like EPUB to POTM conversion in their C++ applications. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to export EPUB to PPTX and then convert PPTX to POTM respectively.
The Aspose.PDF for C++ API allows developers to export EPUB files to PPTX format. It supports all the features of EPUB files, including text, images, tables, hyperlinks, etc. It also provides the ability to convert EPUB files to other popular formats like PDF, HTML, XPS, etc.
The Aspose.Slides for C++ API helps developers to convert PPTX files to POTM format. It supports all the features of PPTX files, including text, images, tables, animations, etc. It also provides the ability to convert PPTX files to other popular formats like PDF, HTML, XPS, etc.
By using Aspose.Total for C++, developers can easily integrate the feature of EPUB to POTM conversion in their C++ applications. It provides a simple and efficient way to export EPUB to PPTX and then convert PPTX to POTM.
C++ API to Export EPUB to POTM
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 Potm format prs->Save(u"output.potm", Aspose::Slides::Export::SaveFormat::Potm);
Change Password of EPUB Document via C++
In the process of rendering EPUB to POTM, 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 POTM File via C++
After converting EPUB to POTM, 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 POTM file
// instantiate a Presentation object that represents a POTM file auto pres = System::MakeObject<Presentation>("output.potm"); // 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.potm", SaveFormat::Potm);

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 POTM File Format?
POTM is a file format used in Microsoft PowerPoint to store presentation templates that also include macros. Similar to the POTX format, POTM files are part of the Office Open XML (OOXML) format introduced in PowerPoint 2007.
The “M” in POTM stands for macros, indicating that these templates can contain VBA (Visual Basic for Applications) code that automates tasks and enhances the functionality of the presentation. This allows users to create dynamic and interactive templates that go beyond static design elements.
POTM files offer the same benefits as POTX files in terms of providing pre-designed slide layouts, formatting, and styles. However, the inclusion of macros adds an extra layer of interactivity and automation to the templates. Macros can perform tasks such as data manipulation, calculations, slide transitions, and user interactions, making presentations more engaging and efficient.
To use a POTM file, users can open it in PowerPoint or select it as a template when creating a new presentation. The macros embedded in the POTM template can be executed and interacted with during the presentation, providing enhanced functionality beyond what is possible with a standard template.
It’s important to note that due to security concerns, some systems and organizations may have restrictions on running macros in PowerPoint presentations. In such cases, users may need to adjust their security settings or obtain necessary permissions to enable the execution of macros in POTM files.
POTM files are compatible with different versions of PowerPoint on various platforms, allowing users to create and share templates with macros across different devices and environments. They provide a powerful tool for creating interactive and automated presentations, offering greater flexibility and customization options for users.
