Render TEX to PPSX within C++ Applications
Convert TEX to PPSX within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer, you may need to integrate the feature of TEX to PPSX conversion inside your C++ applications. TEX is a plain text file format for representing a document and PPSX is a Microsoft PowerPoint Open XML Presentation format. Converting TEX to PPSX can help you to create presentations from the documents.

C++ API to Export TEX to PPSX
- Open TEX file using Document class reference
- Convert TEX to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to PPSX format using
Save
member function and set
Ppsxas 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 TEX file with an instance of Document class
auto doc = MakeObject<Document>(u"template.tex");
// save TEX 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 TEX Document via C++
In the process of rendering TEX to PPSX, you can open a password protected TEX and also change its password. In order to change the password of a TEX 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 TEX Document
auto doc = MakeObject<Document>(L"input.tex", L"owner");
// change password of TEX 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 TEX 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);
