Are you a C++ developer looking to add to integrate MHTML to POT conversion feature inside your C++ applications? You can do it in two simple steps. You can export MHTML to PPTX by using Aspose.PDF for C++ . Secondly, by using Aspose.Slides for C++ , you can convert PPTX to POT. Both APIs come under Aspose.Total for C++ package.
C++ API to Export MHTML to POT
- Open MHTML file using Document class reference
- Convert MHTML to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to POT format using
member function and set
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
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load MHTML file with an instance of Document class auto doc = MakeObject<Document>(u"template.mhtml"); // save MHTML 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 Pot format prs->Save(u"output.pot", Aspose::Slides::Export::SaveFormat::Pot);
Change Password of MHTML Document via C++
In the process of rendering MHTML to POT, you can open a password protected MHTML and also change its password. In order to change the password of a MHTML 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 MHTML Document auto doc = MakeObject<Document>(L"input.mhtml", L"owner"); // change password of MHTML Document doc->ChangePasswords(L"owner", L"newuser", L"newuser"); // save the document doc->Save(L"output.Doc");
Add Images From Web in POT File via C++
After converting MHTML to POT, 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 POT file
// instantiate a Presentation object that represents a POT file auto pres = System::MakeObject<Presentation>("output.pot"); // 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.pot", SaveFormat::Pot);

What is MHTML File Format
MHTML, short for MIME HTML, is a web page archive format used to combine resources that are typically represented by external links (such as images, Flash animations, Java applets, and audio files) with HTML code into a single file. The resulting file can be saved and opened by web browsers.MHTML is supported by most major web browsers, including Microsoft Edge, Internet Explorer, Google Chrome, Mozilla Firefox, and Opera. Safari has limited support for MHTML. When a web page is saved as an MHTML file, the HTML code and the resources are typically encoded using the MIME type multipart/related. This type of encoding is necessary in order to maintain the correct sequence of the HTML code and the resources when they are combined into a single file. The MHTML format is often used for archiving web pages or for distributing web pages that need to be viewed offline.Read More
