Aspose.Total for .NET is a powerful package of File Format Automation APIs that makes it easy to render EPUB to POTM in two simple steps. The first step is to use the PDF Processing API, Aspose.PDF for .NET, to transform the EPUB file format into PPTX. This API provides a wide range of features to manipulate PDF documents, such as creating, editing, converting, and merging PDFs.
Once the EPUB file is converted to PPTX, the second step is to use the Presentation Processing API, Aspose.Slides for .NET, to convert the PPTX to POTM. This API provides a comprehensive set of features to create, edit, and manipulate presentations, such as adding text, images, shapes, and charts. It also supports a wide range of presentation formats, including PPTX, PPT, PPS, POTM, POTX, and PPSX.
Using Aspose.Total for .NET, you can quickly and easily render EPUB to POTM in two simple steps. The PDF Processing API, Aspose.PDF for .NET, is used to convert the EPUB file format to PPTX. Then, the Presentation Processing API, Aspose.Slides for .NET, is used to convert the PPTX to POTM. This package of File Format Automation APIs provides a comprehensive set of features to create, edit, and manipulate documents and presentations.
.NET API to Convert EPUB to POTM
Get Started with .NET File Format APIs
Install from command line as
nuget install Aspose.Total or via Package Manager Console of Visual Studio with
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
Document document = new Document("input.epub"); // save EPUB as a PPTX document.Save("PptxOutput.pptx", SaveFormat.Pptx); // load PPTX with an instance of Presentation Presentation presentation = new Presentation("PptxOutput.pptx"); // call save method while passing SaveFormat.Potm presentation.Save("output.potm", SaveFormat.Potm);
Get XMP Metadata from EPUB File via .NET
While converting EPUB to POTM, you might need extra XMP metadata information to prioritize your batch conversion process. For example you can get and sort your conversion documents based on creation date and process the documents accordingly. Aspose.PDF for .NET allows you to access a EPUB file’s XMP metadata. To get a EPUB file’s metadata, you can create a Document object and open the input EPUB file. After that, you can get the file’s metadata using the Metadata property.
Document doc = new Document("input.epub"); // get EPUB XMP properties Console.WriteLine(doc.Metadata["xmp:CreateDate"]); Console.WriteLine(doc.Metadata["xmp:Nickname"]); Console.WriteLine(doc.Metadata["xmp:CustomProperty"]);
Create Read Only POTM File via .NET
By using Aspose.Slides for .NET API, you can further enhance the features of your conversion application. One of the feature can be to create your output file read only to increase security. The API allows you to set your POTM file to Read-Only, which means users (after they open the presentation) see the Read-Only recommendation.
Presentation presentation = new Presentation("PptxOutput.pptx"); // make POTM read only presentation.ProtectionManager.ReadOnlyRecommended = true; // call save method while passing SaveFormat.Potm presentation.Save("output.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.
