Render XML to POTX within C++ Applications
Convert XML to POTX within your C++ Applications without using Microsoft® PowerPoint
Why to Convert XML to POTX?
XML to POTX conversion is a useful feature for C++ developers who want to integrate XML documents into their applications. XML is a popular markup language used to store and transport data, while POTX is a presentation format used by Microsoft PowerPoint. By converting XML to POTX, developers can easily create presentations from XML data and display them in their applications.
How Aspose.Total Helps for XML to POTX Conversion?
Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to integrate XML to POTX conversion into their applications. The suite includes two APIs: Aspose.PDF for C++ and Aspose.Slides for C++. With Aspose.PDF for C++, developers can export XML documents to PPTX format. Then, with Aspose.Slides for C++, they can convert PPTX to POTX. This makes it easy for developers to quickly and easily convert XML to POTX and integrate it into their applications.
C++ API to Export XML to POTX
- Open XML file using Document class reference
- Convert XML 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 XML file with an instance of Document class
auto doc = MakeObject<Document>(u"template.xml");
// save XML 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 XML Document via C++
In the process of rendering XML to POTX, you can open a password protected XML and also change its password. In order to change the password of a XML 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 XML Document
auto doc = MakeObject<Document>(L"input.xml", L"owner");
// change password of XML 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 XML 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);
