Render XPS to XAML within C++ Applications
Convert XPS to XAML within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer and looking to add XPS to XAML conversion feature inside your C++ applications, then you need to convert XPS to XAML. XPS is a fixed-layout document format that is used to store documents in a way that is independent of the application software, hardware, and operating system. XAML is a markup language used to define user interfaces in Windows Presentation Foundation (WPF) applications.
How Aspose.Total helps for XPS to XAML conversion
Aspose.Total for C++ is a suite of APIs that provides a wide range of features for C++ developers. It includes APIs for PDF, Slides, Words, Cells, and Email. To convert XPS to XAML, you can use two APIs from Aspose.Total for C++. First, you can use Aspose.PDF for C++ to export XPS to PPTX. Secondly, you can use Aspose.Slides for C++ to convert PPTX to XAML. Both APIs come under Aspose.Total for C++ package.
The process of XPS to XAML conversion is quite simple. First, you need to export XPS to PPTX by using Aspose.PDF for C++. Then, you can use Aspose.Slides for C++ to convert PPTX to XAML. Aspose.Total for C++ provides a comprehensive set of features for C++ developers to work with PDF, Slides, Words, Cells, and Email. It also provides the feature to convert XPS to XAML in two simple steps.
C++ API to Export XPS to XAML
- 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 XAML format using
Save
member function and set
Xamlas 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 Xaml format
prs->Save(u"output.xaml", Aspose::Slides::Export::SaveFormat::Xaml);
Change Password of XPS Document via C++
In the process of rendering XPS to XAML, 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 XAML File via C++
After converting XPS to XAML, 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 XAML file
// instantiate a Presentation object that represents a XAML file
auto pres = System::MakeObject<Presentation>("output.xaml");
// 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.xaml", SaveFormat::Xaml);
