Render MD to POTM within C++ Applications
Convert MD to POTM within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add to integrate MD to POTM conversion feature inside your C++ applications? You can do it in two simple steps. You can export MD to PPTX by using Aspose.PDF for C++ . Secondly, by using Aspose.Slides for C++ , you can convert PPTX to POTM. Both APIs come under Aspose.Total for C++ package.
C++ API to Export MD to POTM
- Open MD file using Document class reference
- Convert MD to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to POTM format using
Save
member function and set
Potmas 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 MD file with an instance of Document class
auto doc = MakeObject<Document>(u"template.md");
// save MD 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 MD Document via C++
In the process of rendering MD to POTM, you can open a password protected MD and also change its password. In order to change the password of a MD 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 MD Document
auto doc = MakeObject<Document>(L"input.md", L"owner");
// change password of MD 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 MD 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 MD File Format?
MD, or Markdown, is a lightweight markup language commonly used for formatting plain text documents. It was created by John Gruber in 2004 with the goal of allowing writers to focus on content without the distractions of complex formatting. Markdown uses simple and intuitive syntax that can be easily converted into HTML or other document formats.
In Markdown, you can apply formatting to text by using a combination of special characters and plain text. For example, you can use asterisks or underscores to create italic or bold text, hashtags to create headings, and hyphens or asterisks to create lists. Markdown also supports adding links, images, code snippets, and tables.
One of the advantages of Markdown is its readability in its raw form, as it closely resembles plain text. It can be written in any text editor and easily converted into HTML or other formats using various tools and converters. Markdown files have the .md or .markdown file extension.
Markdown is widely used for writing documentation, creating blog posts, and even in version control systems like Git. Its simplicity and versatility have made it a popular choice among writers, developers, and content creators for creating structured and well-formatted documents with minimal effort.
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.
