Render XSLFO to POTM within C++ Applications
Convert XSLFO to POTM within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add to integrate XSLFO to POTM conversion feature inside your C++ applications? You can do it in two simple steps. You can export XSLFO to PPTX by using Aspose.PDF for C++ . Secondly, by using Aspose.Slides for C++ , you can convert PPTX to POTM. Both APIs come under Aspose.Total for C++ package.
C++ API to Export XSLFO to POTM
- 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 POTM format using
Save
member function and set
Potmas 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 Potm format
prs->Save(u"output.potm", Aspose::Slides::Export::SaveFormat::Potm);
Change Password of XSLFO Document via C++
In the process of rendering XSLFO to POTM, 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 POTM File via C++
After converting XSLFO to POTM, 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 POTM file
// instantiate a Presentation object that represents a POTM file
auto pres = System::MakeObject<Presentation>("output.potm");
// 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.potm", SaveFormat::Potm);

What is XSLFO File Format
XSLFO is a XML-based page description language. It is most often used to generate PDF documents from XML data. XSLFO defines the layout and appearance of pages and page elements. It includes features for defining the size and position of pages and page elements, the font and color of text, and the rules for flowing text from one page to another. XSLFO is part of the XSLT standard, and can be used with any XML document.

Microsoft PowerPoint Template File POTM format is a file format used to store PowerPoint templates. A POTM file contains a PowerPoint template, which includes slide layouts, colors, fonts, and other design elements. POTM files are used to create new PowerPoint presentations from scratch, or to modify existing PowerPoint presentations. When you create a new PowerPoint presentation, you can choose to use a blank template, or you can select a template from the available options. If you select a template, the POTM file for that template will be downloaded from the Microsoft website and saved on your computer. When you open the PowerPoint application, the template will be loaded and you can begin creating your presentation.If you want to modify an existing PowerPoint presentation, you can open the POTM file for that presentation in PowerPoint and make changes to the template. For example, you can change the slide layout, colors, fonts, or other design elements. Once you have made your changes, you can save the POTM file and use it to create a new PowerPoint presentation.
