Render MHTML to PPSM within C++ Applications
Convert MHTML to PPSM within your C++ Applications without using Microsoft® PowerPoint
Why to Convert MHTML to PPSM?
MHTML (MIME HTML) is a web page archive format used to save webpages in a single file. It is a combination of HTML code and resources like images, audio, and video. On the other hand, PPSM (PowerPoint Show) is a presentation format used by Microsoft PowerPoint. It is used to save presentations in a single file. Therefore, if you are a C++ developer and want to integrate MHTML to PPSM conversion feature inside your C++ applications, you need to convert MHTML to PPSM.

To convert MHTML to PPSM, you can use two APIs from Aspose.Total for C++ package. First, you can use Aspose.PDF for C++ to export MHTML to PPTX. Secondly, you can use Aspose.Slides for C++ to convert PPTX to PPSM. Both APIs are easy to use and offer a wide range of features. They also provide the flexibility to customize the output according to your requirements. Moreover, they are available for various platforms such as Windows, Linux, and Mac. Therefore, you can easily integrate MHTML to PPSM conversion feature inside your C++ applications by using Aspose.Total for C++ package.
C++ API to Export MHTML to PPSM
- 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 PPSM format using
Save
member function and set
Ppsmas 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 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 Ppsm format
prs->Save(u"output.ppsm", Aspose::Slides::Export::SaveFormat::Ppsm);
Change Password of MHTML Document via C++
In the process of rendering MHTML to PPSM, 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 PPSM File via C++
After converting MHTML to PPSM, 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 PPSM file
// instantiate a Presentation object that represents a PPSM file
auto pres = System::MakeObject<Presentation>("output.ppsm");
// 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.ppsm", SaveFormat::Ppsm);
