Render MD to OTP within C++ Applications
Convert MD to OTP within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add to integrate MD to OTP 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 OTP. Both APIs come under Aspose.Total for C++ package.
C++ API to Export MD to OTP
- 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 OTP format using
Save
member function and set
Otpas 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 Otp format
prs->Save(u"output.otp", Aspose::Slides::Export::SaveFormat::Otp);
Change Password of MD Document via C++
In the process of rendering MD to OTP, 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 OTP File via C++
After converting MD to OTP, 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 OTP file
// instantiate a Presentation object that represents a OTP file
auto pres = System::MakeObject<Presentation>("output.otp");
// 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.otp", SaveFormat::Otp);

What is MD File Format
Markdown is a lightweight and easy-to-use syntax for styling all forms of writing on the GitHub platform. From your READMEs and in-line comments to documentation for your repositories and blog posts, Markdown is designed to make writing on the web easy to read, easy to write, and still look great.In addition to the basics of Markdown, you can also include images, links, and code blocks in your documents. You can even use a subset of HTML in your Markdown documents if you need more control over the display of your content.Markdown is not a replacement for HTML, nor is it a replacement for a rich text editor. It is simply a way to make writing on the web more accessible and easy to read.

OpenDocument Standard Format (ODF) is an XML-based file format for representing electronic documents such as spreadsheets, charts, presentations and word processing documents. The format is standardized by the Organization for the Advancement of Structured Information Standards (OASIS) and was first adopted by ISO/IEC JTC1 SC34 in 2005. ODF is an open format, meaning that it is not restricted by any copyright or patent.ODF is based on the XML schema of the OpenOffice.org office suite and uses the Zip compression algorithm. It is designed to be platform-independent and to be able to support a wide range of applications. The OpenDocument Format specification defines three document types:* Text documents* Spreadsheets* PresentationsEach document type has a corresponding XML schema. The schemas are designed to be extended, allowing application-specific features to be added.ODF documents can be encrypted and signed using the XML Encryption and XML Signature standards. The OpenDocument Format is supported by a number of office applications, including Apache OpenOffice, LibreOffice, IBM Lotus Symphony and Microsoft Office.
