Render XSLFO to PPSX within C++ Applications
Convert XSLFO to PPSX within your C++ Applications without using Microsoft® PowerPoint
Why to Convert XSLFO to PPSX
C++ developers often need to integrate XSLFO to PPSX conversion feature inside their applications. XSLFO (XSL Formatting Objects) is a markup language for XML document formatting which is most commonly used to generate PDF documents. PPSX is a Microsoft PowerPoint Open XML Slide Show file which is used to store slides created using Microsoft PowerPoint. Converting XSLFO to PPSX allows users to view the content of the XSLFO document in the form of a presentation.
How Aspose.Total Helps for XSLFO to PPSX Conversion
Aspose.Total for C++ is a comprehensive package of APIs that helps developers to create, manipulate and convert various file formats. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to convert XSLFO to PPSX.
The first step is to export XSLFO to PPTX by using Aspose.PDF for C++. This API provides a wide range of features to create, read, edit and convert PDF documents. It also allows developers to convert PDF documents to various other file formats, including PPTX.
The second step is to convert PPTX to PPSX by using Aspose.Slides for C++. This API provides a wide range of features to create, read, edit and convert presentations. It also allows developers to convert presentations to various other file formats, including PPSX.
In conclusion, Aspose.Total for C++ is an ideal package for C++ developers who need to integrate XSLFO to PPSX conversion feature inside their applications. It provides two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to convert XSLFO to PPSX in two simple steps.
C++ API to Export XSLFO to PPSX
- Open XSLFO file using Document class reference
- Convert XSLFO 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 XSLFO file with an instance of Document class
auto doc = MakeObject<Document>(u"template.xslfo");
// save XSLFO 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 XSLFO Document via C++
In the process of rendering XSLFO to PPSX, you can open a password protected XSLFO and also change its password. In order to change the password of a XSLFO 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 XSLFO Document
auto doc = MakeObject<Document>(L"input.xslfo", L"owner");
// change password of XSLFO 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 XSLFO 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);
