Render XPS to POTX within C++ Applications
Convert XPS to POTX within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
Are you a C++ developer looking to add a feature to integrate XPS to POTX conversion inside your C++ applications? XPS is a fixed-layout document format developed by Microsoft and is used to store documents in an XML-based format. POTX is a PowerPoint Open XML template file format used to store PowerPoint presentations. Converting XPS to POTX can help you create presentations with a consistent look and feel.
How Aspose.Total Helps for XPS to POTX Conversion
You can easily export XPS to PPTX by using Aspose.PDF for C++. It is a powerful PDF processing API that enables you to create, read, edit, and convert PDF documents. It also allows you to export XPS to PPTX format. Secondly, by using Aspose.Slides for C++, you can convert PPTX to POTX. It is a powerful presentation processing API that enables you to create, read, edit, and convert presentations. Both APIs come under Aspose.Total for C++ package. Aspose.Total for C++ is a suite of APIs that provides a comprehensive set of features for working with PDF, Word, Excel, PowerPoint, and other file formats. It allows you to create, read, edit, and convert documents and presentations in various formats. With Aspose.Total for C++, you can easily export XPS to POTX in two simple steps.
C++ API to Export XPS to POTX
- Open XPS file using Document class reference
- Convert XPS 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 XPS file with an instance of Document class
auto doc = MakeObject<Document>(u"template.xps");
// save XPS 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 XPS Document via C++
In the process of rendering XPS to POTX, you can open a password protected XPS and also change its password. In order to change the password of a XPS 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 XPS Document
auto doc = MakeObject<Document>(L"input.xps", L"owner");
// change password of XPS 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 XPS 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);
