Render XSLFO to POTX within C++ Applications
Convert XSLFO to POTX within your C++ Applications without using Microsoft® PowerPoint
Why to Convert XSLFO to POTX?
If you are a C++ developer looking to add a feature to your application that allows for the conversion of XSLFO to POTX, then you have come to the right place. XSLFO (Extensible Stylesheet Language Formatting Objects) is a markup language used to describe the formatting of a document. It is used to define the layout of a document, such as the font, size, color, and other formatting options. POTX (PowerPoint Open XML) is a file format used by Microsoft PowerPoint to store presentations. It is an open standard that allows for the exchange of presentation data between different applications.
How Aspose.Total Helps for XSLFO to POTX Conversion?
The conversion of XSLFO to POTX can be done in two simple steps. First, you can use Aspose.PDF for C++ to export XSLFO to PPTX. Aspose.PDF for C++ is a powerful PDF processing API that allows developers to create, edit, and convert PDF documents. Secondly, you can use Aspose.Slides for C++ to convert PPTX to POTX. Aspose.Slides for C++ is a powerful presentation processing API that allows developers to create, edit, and convert presentations. Both APIs are available as part of the Aspose.Total for C++ package. Aspose.Total for C++ is a suite of APIs that provides developers with a comprehensive set of tools for developing applications with C++. It includes APIs for working with PDF, Word, Excel, PowerPoint, and other file formats.
C++ API to Export XSLFO to POTX
- 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 POTX format using
Save
member function and set
Potxas 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 Potx format
prs->Save(u"output.potx", Aspose::Slides::Export::SaveFormat::Potx);
Change Password of XSLFO Document via C++
In the process of rendering XSLFO to POTX, 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 POTX File via C++
After converting XSLFO to POTX, 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 POTX file
// instantiate a Presentation object that represents a POTX file
auto pres = System::MakeObject<Presentation>("output.potx");
// 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.potx", SaveFormat::Potx);
