Render XPS to PPT within C++ Applications
Convert XPS to PPT within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add the ability to convert XPS to PPT files inside your C++ applications? You can do it in two simple steps with the help of Aspose.Total for C++. Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to create, manipulate, and convert documents, images, and other file formats.
The first step is to export XPS to PPTX by using Aspose.PDF for C++. Aspose.PDF for C++ is a powerful API that enables developers to create, edit, and convert PDF documents. It also provides the ability to export XPS to PPTX.
The second step is to convert PPTX to PPT by using Aspose.Slides for C++. Aspose.Slides for C++ is a powerful API that enables developers to create, edit, and convert presentations. It also provides the ability to convert PPTX to PPT.
By using Aspose.Total for C++, developers can easily add the ability to convert XPS to PPT files inside their C++ applications. It is a comprehensive suite of APIs that provides developers with the tools they need to create, manipulate, and convert documents, images, and other file formats.
C++ API to Export XPS to PPT
- 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 PPT format using
Save
member function and set
Pptas 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 Ppt format
prs->Save(u"output.ppt", Aspose::Slides::Export::SaveFormat::Ppt);
Change Password of XPS Document via C++
In the process of rendering XPS to PPT, 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 PPT File via C++
After converting XPS to PPT, 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 PPT file
// instantiate a Presentation object that represents a PPT file
auto pres = System::MakeObject<Presentation>("output.ppt");
// 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.ppt", SaveFormat::Ppt);
