Render MHTML to POTM within C++ Applications
Convert MHTML to POTM within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
Are you a C++ developer looking to add a feature to your C++ applications that will allow you to convert MHTML to POTM? MHTML is a web page archive format that is used to store web pages in a single file. POTM is a Microsoft PowerPoint Open XML Macro-Enabled Presentation format that is used to store presentations. Converting MHTML to POTM can be a useful feature for C++ developers who need to store web pages in a presentation format.
How Aspose.Total Helps for MHTML to POTM Conversion
Integrating MHTML to POTM conversion into your C++ applications can be done in two simple steps with the help of Aspose.Total for C++. Aspose.Total for C++ is a suite of APIs that provides developers with the tools they need to create, manipulate, and convert documents and images. The first step is to use Aspose.PDF for C++ to export MHTML to PPTX. Aspose.PDF for C++ is a powerful PDF manipulation API that allows developers to create, edit, and convert PDF documents. The second step is to use Aspose.Slides for C++ to convert PPTX to POTM. Aspose.Slides for C++ is a powerful presentation manipulation API that allows developers to create, edit, and convert presentations. With the help of Aspose.Total for C++, developers can easily integrate MHTML to POTM conversion into their C++ applications.
C++ API to Export MHTML to POTM
- 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 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 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 Potm format
prs->Save(u"output.potm", Aspose::Slides::Export::SaveFormat::Potm);
Change Password of MHTML Document via C++
In the process of rendering MHTML to POTM, 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 POTM File via C++
After converting MHTML 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);
