Render XPS to PPS within C++ Applications
Convert XPS to PPS within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer, you may need to integrate XPS to PPS conversion feature inside your C++ applications. XPS and PPS are two different file formats and you may need to convert one to another for various reasons. For example, you may need to convert XPS to PPS to make the file compatible with a certain application or to make the file more accessible to other users.

To export XPS to PPTX, you can use Aspose.PDF for C++. It is a powerful API that can help you to convert XPS to PPTX in just a few lines of code. It also provides a wide range of features that can help you to customize the output PPTX file.
Once you have exported XPS to PPTX, you can use Aspose.Slides for C++ to convert PPTX to PPS. It is a feature-rich API that can help you to convert PPTX to PPS with ease. It also provides a wide range of features that can help you to customize the output PPS file.
In conclusion, Aspose.Total for C++ is a comprehensive suite of APIs that can help you to easily and quickly convert XPS to PPS. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to export XPS to PPTX and convert PPTX to PPS respectively.
C++ API to Export XPS to PPS
- Open XPS file using Document class reference
- Convert XPS to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to PPS format using
Save
member function and set
Ppsas 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 XPS file with an instance of Document class
auto doc = MakeObject<Document>(u"template.xps");
// save XPS 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 Pps format
prs->Save(u"output.pps", Aspose::Slides::Export::SaveFormat::Pps);
Change Password of XPS Document via C++
In the process of rendering XPS to PPS, you can open a password protected XPS and also change its password. In order to change the password of a XPS 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 XPS Document
auto doc = MakeObject<Document>(L"input.xps", L"owner");
// change password of XPS Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in PPS File via C++
After converting XPS to PPS, 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 PPS file
// instantiate a Presentation object that represents a PPS file
auto pres = System::MakeObject<Presentation>("output.pps");
// 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.pps", SaveFormat::Pps);
