Render XPS to PPSM within C++ Applications
Convert XPS to PPSM within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer and you need to integrate XPS to PPSM conversion feature inside your C++ applications, then you need to convert XPS to PPSM. XPS is a fixed document format developed by Microsoft and PPSM is a PowerPoint Slide Show format.
How Aspose.Total helps for XPS to PPSM Conversion
Aspose.Total for C++ is a package that contains all the APIs of Aspose for C++. It includes Aspose.PDF for C++ and Aspose.Slides for C++. You can use Aspose.PDF for C++ to export XPS to PPTX and Aspose.Slides for C++ to convert PPTX to PPSM. Both APIs are available in Aspose.Total for C++ package.
Aspose.PDF for C++ is a powerful PDF manipulation API that enables you to create, read, edit, and convert PDF documents. It also allows you to export XPS to PPTX. Aspose.Slides for C++ is a powerful presentation manipulation API that enables you to create, read, edit, and convert presentations. It also allows you to convert PPTX to PPSM.
By using Aspose.Total for C++, you can easily integrate XPS to PPSM conversion feature inside your C++ applications in two simple steps. First, you can export XPS to PPTX by using Aspose.PDF for C++. Secondly, you can convert PPTX to PPSM by using Aspose.Slides for C++. Both APIs come under Aspose.Total for C++ package.
C++ API to Export XPS to PPSM
- 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 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 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 Ppsm format
prs->Save(u"output.ppsm", Aspose::Slides::Export::SaveFormat::Ppsm);
Change Password of XPS Document via C++
In the process of rendering XPS to PPSM, 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 PPSM File via C++
After converting XPS 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);
