Render EPUB to PPTM within C++ Applications
Convert EPUB to PPTM within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer looking to add the ability to convert EPUB to PPTM inside your C++ applications, then you need to convert EPUB to PPTX and then PPTX to PPTM. This is because PPTM is a Microsoft PowerPoint macro-enabled presentation format, which is not supported by EPUB.
How Aspose.Total Helps for EPUB to PPTM Conversion
Aspose.Total for C++ is a suite of APIs that provides developers with the ability to create, manipulate, and convert various file formats. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to convert EPUB to PPTM.
To export EPUB to PPTX, you can use Aspose.PDF for C++. This API allows you to convert EPUB to PPTX with just a few lines of code. It also supports a wide range of other file formats, such as PDF, XPS, HTML, and more.
Once you have converted EPUB to PPTX, you can use Aspose.Slides for C++ to convert PPTX to PPTM. This API provides a wide range of features, such as the ability to create, edit, and convert presentations. It also supports a wide range of other file formats, such as PPT, PPS, PPTX, PPSX, and more.
By using Aspose.Total for C++, you can easily convert EPUB to PPTM in just two simple steps. This suite of APIs provides developers with the ability to create, manipulate, and convert various file formats, making it an ideal choice for C++ developers looking to add the ability to convert EPUB to PPTM inside their applications.
C++ API to Export EPUB to PPTM
- 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 PPTM format using
Save
member function and set
Pptmas 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 Pptm format
prs->Save(u"output.pptm", Aspose::Slides::Export::SaveFormat::Pptm);
Change Password of EPUB Document via C++
In the process of rendering EPUB to PPTM, 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 PPTM File via C++
After converting EPUB to PPTM, 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 PPTM file
// instantiate a Presentation object that represents a PPTM file
auto pres = System::MakeObject<Presentation>("output.pptm");
// 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.pptm", SaveFormat::Pptm);

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 PPTM File Format?
The PPTM file format is a file extension used by Microsoft PowerPoint to save presentations that contain macros. It is an extension of the PPTX file format, which is the default file format for PowerPoint presentations. The “M” in PPTM stands for “macro-enabled” indicating that the file can contain embedded macros written in the Visual Basic for Applications (VBA) programming language.
PPTM files are created and edited using Microsoft PowerPoint or other compatible software that supports the PowerPoint file format. These files can include various multimedia elements such as text, images, videos, audio, and animations. Additionally, PPTM files can incorporate interactive features and custom functionalities through the use of macros.
Macros in PPTM files allow users to automate repetitive tasks, create interactive content, and add custom functionality to their presentations. Macros can be written using the VBA programming language and can perform a wide range of operations, including data manipulation, user input handling, and integration with other software applications.
When opening a PPTM file, PowerPoint may prompt the user to enable or disable macros for security reasons, as macros can potentially execute malicious code. It is important to exercise caution when opening PPTM files from unknown or untrusted sources.
