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);

What is XPS File Format?
XPS, short for XML Paper Specification, is a file format created by Microsoft to represent fixed-layout documents. XPS files contain the content and print settings of a document, making them suitable for preserving the layout and appearance of a document across different devices and platforms.
The XPS format is based on XML (eXtensible Markup Language), a widely used markup language for structured data representation. XPS files encapsulate document content, such as text, images, vector graphics, and annotations, in a structured XML format. This enables easy interpretation and rendering of the document’s visual elements.
XPS files are conceptually similar to PDF (Portable Document Format) files in that they both aim to provide a reliable way to present and share documents while preserving their formatting and layout. However, PDF files have gained broader support across different software applications and hardware devices, making them more widely accepted and compatible.
To view and work with XPS files, Microsoft provides an XPS Viewer as part of the Windows operating system. Various third-party applications and tools also offer support for opening, creating, and converting XPS files. However, compared to PDF, the range of software and hardware supporting the XPS format may be more limited.
What is XAML File Format?
XAML (Extensible Application Markup Language) is an XML-based language developed by Microsoft for initializing objects and defining structured values. It is extensively used in Microsoft’s WPF (Windows Presentation Foundation) technology for designing and building advanced user interfaces.
With XAML, it is possible to create a wide range of objects, including user interface elements such as buttons, text boxes, and media elements. Additionally, non-user interface objects such as brushes and geometries can also be defined using XAML.
Typically, XAML is compiled into a binary format that can be executed by a XAML processor. The XAML processor can be a standalone application like Microsoft’s Expression Blend tool or integrated into another application such as Microsoft’s Visual Studio IDE. When used in conjunction with WPF, XAML files are commonly compiled into a binary format known as BAML (Binary Application Markup Language). BAML is a more efficient format for storing and processing XAML-based user interface elements.
While XAML files are often compiled into binary formats, they can also be stored in a text-based format using XML (Extensible Markup Language). XML-based XAML files can be edited using any text editor due to the flexibility of XML. However, it is important to note that XML-based XAML files tend to be larger in size and may take longer to process compared to their binary counterparts.
