Render XSLFO to PPT within C++ Applications
Convert XSLFO to PPT within your C++ Applications without using Microsoft® PowerPoint
Why to Convert XSLFO to PPT?
XSLFO (XSL Formatting Objects) is a markup language for XML documents, which is used to define the layout of a document. It is used to create documents such as PDFs, PostScript, and PPTs. PPT (PowerPoint Presentation) is a popular presentation format used by businesses and individuals to create presentations. Converting XSLFO to PPT allows users to create presentations with the same look and feel as a PDF or PostScript document.
How Aspose.Total Helps for XSLFO to PPT Conversion?
Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to easily integrate XSLFO to PPT conversion into their C++ applications. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to export XSLFO to PPTX and then convert PPTX to PPT, respectively. Aspose.PDF for C++ allows developers to export XSLFO to PPTX with just a few lines of code. Aspose.Slides for C++ then enables developers to convert PPTX to PPT with the same ease. Both APIs are easy to use and provide a wide range of features that make it easy to create high-quality presentations.
C++ API to Export XSLFO to PPT
- 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 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 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 Ppt format
prs->Save(u"output.ppt", Aspose::Slides::Export::SaveFormat::Ppt);
Change Password of XSLFO Document via C++
In the process of rendering XSLFO to PPT, 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 PPT File via C++
After converting XSLFO 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);
