Why to Convert

If you are a C++ developer looking to add the ability to convert EPUB to POTX inside your C++ applications, then you need to use a reliable and efficient solution. This is because EPUB and POTX are two different file formats and require a conversion process to be able to use them together.

How Aspose.Total Helps for EPUB to POTX Conversion

Aspose.Total for C++ is a comprehensive suite of APIs that allows developers to easily integrate document conversion features into their C++ applications. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to convert EPUB to POTX in two simple steps. First, you can use Aspose.PDF for C++ to export EPUB to PPTX. Then, you can use Aspose.Slides for C++ to convert PPTX to POTX. Both APIs are included in the Aspose.Total for C++ package, making it easy to access and use them.

C++ API to Export EPUB to POTX

  1. Open EPUB file using Document class reference
  2. Convert EPUB to PPTX by using Save method function
  3. Load PPTX document by using Presentation class reference
  4. Save the document to POTX format using Save member function and set Potx as 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 Potx format
prs->Save(u"output.potx", Aspose::Slides::Export::SaveFormat::Potx);  

Change Password of EPUB Document via C++

In the process of rendering EPUB to POTX, 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

Add Images From Web in POTX File via C++

After converting EPUB to POTX, 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 POTX file

// instantiate a Presentation object that represents a POTX file
auto pres = System::MakeObject<Presentation>("output.potx");
// 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.potx", SaveFormat::Potx);

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 POTX File Format?

POTX is a file format used in Microsoft PowerPoint to store presentation templates. It is part of the Office Open XML (OOXML) format introduced in PowerPoint 2007 and is an evolution of the older POT format. The “X” in POTX signifies the XML-based nature of the format.

POTX files contain pre-designed slide layouts, formatting, and styles that can be applied to new presentations. These templates serve as a starting point for creating consistent and visually appealing slideshows. They can include placeholders for text, images, charts, tables, and other multimedia elements, allowing users to customize the content while maintaining a consistent design.

The use of POTX files offers several advantages. They allow users to save time and effort by reusing predefined layouts and designs, ensuring a consistent look and feel across presentations. They also enable organizations to establish brand identity and enforce corporate design standards by providing templates with company-specific branding elements.

To use a POTX file, users can simply open it in PowerPoint or select it as a template when creating a new presentation. PowerPoint provides editing tools to modify the template and customize the content as needed. Additionally, users can save their own customized templates in the POTX format for future use or sharing with others.

POTX files are widely compatible with different versions of PowerPoint on various platforms, including Windows, macOS, and mobile devices. They provide a convenient way to streamline the presentation creation process and maintain consistency in visual design and formatting.
