Are you a C++ developer looking to add to integrate MHTML to PPSX 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 PPSX. Both APIs come under Aspose.Total for C++ package.
C++ API to Export MHTML to PPSX
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 Ppsx format prs->Save(u"output.ppsx", Aspose::Slides::Export::SaveFormat::Ppsx);
Change Password of MHTML Document via C++
In the process of rendering MHTML to PPSX, 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 PPSX File via C++
After converting MHTML to PPSX, 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 PPSX file
// instantiate a Presentation object that represents a PPSX file auto pres = System::MakeObject<Presentation>("output.ppsx"); // 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.ppsx", SaveFormat::Ppsx);
