The NiXPS SDK is a cross-platform software development kit designed for reading, writing, manipulating, and rendering XPS (XML Paper Specification) documents. Developed by the Belgian company NiXPS, it provides software engineering teams with the foundational tools needed to natively integrate high-performance XPS document processing directly into their applications. Core Functionality
Dual-Level Access: Offers powerful high-level automation wrappers alongside granular, low-level access to the internal XML structures, layers, and parts of an XPS package.
Manipulation & Editing: Allows developers to insert text, append or reorder pages, strip metadata, and inject variable data workflows directly into document streams.
Format Conversion: Features highly efficient document conversion pipelines to accurately transform XPS inputs into scalable, searchable PDF or long-term preservation PDF/A files.
Rendering Engine: Delivers precise vector-graphics and font rendering to display crisp, high-fidelity document previews across various operating systems. Supported Frameworks & Distribution
The SDK is packaged as a compiled native shared library—distributed as a .dll and .lib on Windows, and a .dylib on macOS. Because it is built with a strict, compiler-independent C/C++ interface, it can easily link to almost any application.
To cater to different software stacks, it is officially offered in two primary flavors:
C/C++ Native Wrapper: Includes documented C++ “glue sources” that act as a clean, object-oriented shield over the low-level C library.
.NET Managed Library: Provides fully integrated API bindings for .NET and Windows Presentation Foundation (WPF) environments, streamlining the generation and editing of WPF FixedDocument sequences. Available SDK Tiers
Depending on application demands, NiXPS historically split the library into specific operational tiers:
NiXPS Processing SDK: Tailored for lightweight server and client environments requiring high-speed document viewing, parsing, and conversion.
NiXPS Library SDK: Features the complete extension engine built for advanced structural modification, content editing, and deep asset extraction.
NiXPS OEM SDK: An extensible, modular architecture meant for organizations aiming to build custom white-label applications or deep integrations directly on top of the standalone NiXPS software ecosystem.

If you are evaluating this library for a project, please let me know: What programming language ( , C++, etc.) is your application built with?
What specific tasks (e.g., extracting text, printing, converting to PDF) do you need to perform?
Which target operating systems do you plan to deploy your application to? I can give you more specific guidance based on your setup. NiXPS SDK v2.6
