PDF Xpansion SDK 14 with ZUGFeRD 2.1.1/2.0, Factur-X & XRechnung

Development Tool: Integration in Applications

PDF Xpansion SDK 14

The PDF Developer Tool provides powerful APIs to help you develop PDF/XPS-enabled applications and/or software solutions. Among other things, it offers you a wide range of options for creating and editing PDF, PDF/A or XPS documents, for displaying and printing them on paper, for converting between these formats, exporting and/or importing from/to other file formats. With this API, you can easily integrate PDF functions into both Windows desktop applications for the PC and Windows Apps.
A ZUGFeRD 2.1.1/2.0, Factur-X and XRechnung API was added to the PDF SDK for Eu-compliant invoicing according to standard 16931.

Well-known companies rely on PDF Xpansion Technology


New in version 14

Conversion of electronic invoice formats: This function enables the automatic conversion of XML files of the electronic invoice formats ZUGFeRD (Version 1.0 with special features)*, XRechnung and Factur-X among each other. For example, an XRechnung XML can be opened, converted to ZUGFeRD 2.0 and saved.

*Exceptions to the implementation of the conversion function apply if ZUGFeRD 1.0 is the source or target format, among other things because higher ZUGFeRD versions require elements in the XML file as mandatory, which are not present according to ZUGFeRD 1.0.

Support of the latest eInvoice formats for output & incoming invoices: The SDK offers the standards ZUGFeRD 1.0 to 2.1.1 (all profiles) and XRechnung 1.2.2 (valid until 31.12.2020) and 2.0 (valid from 1.1.2021). Both XRechnung versions are supported as XRechnung profile within the hybrid ZUGFeRD 2.1.1 format (PDF/A-3 and embedded XML file) and for XML-based invoices only. The current version of the SDK also supports UBL syntax for importing data from XRechnung (invoice receipt). The soft Xpansion solution enables the comprehensive fulfillment of the requirements of the internationally valid EU directives 2014/55/EU, the EN 16931 standard as well as the implementation into national law through the e-invoice law and e-invoice regulation.

Functional Scope of PDF Xpansion SDK 14

Detailed information can be found at bottom of this page.

  • Support of Windows 10 and of UWP (Universal Windows Platform) for applications for all Windows 10 devices
  • ZUGFeRD – API: comprehensive validation of incoming ZUGFeRD files (electronic invoices), read structured und unstructured invoice data, display and / or print PDF part of invoice in viewer, save outgoing invoices as ZUGFeRD compliant files (including conversion of visual part of invoice to PDF/A-3 format and invoice data to embedded XML attachment), Support of all ZUGFeRD profiles
  • API for Factur-X and XRechnung
  • Fully adequate Page Content Editor Tool in PDF viewer: enables end user to edit content of pages
  • Conversion from/to several formats: XPS/OXPS, TXT, raster images, SVG, EMF, HTML, MathML, DOCX
  • Support of nearly all world languages
  • Display and process dynamic forms (XFA format) for applications created with C++ and .NET: preview in viewer (without filling possibility), printing.
  • Usage of API for access to form data (read & fill)
The PDF Xpansion SDK 13 enables you to implement all current PDF/A standards (1, 2 and 3) and all conformity levels (a, b, u) into your applications. In contrast to PDF/A-1, files that comply with the PDF/A-2 standard may use JPG2000 compression, transparencies and layers. And they are allowed to have PDF/A files embedded. On the other hand, the PDF/A-3 standard allows embedding files of any type, not just PDF/A files. This liberalization of the standard has several implications: for example, you may now enable the users of document archiving and DMS solutions to embed the source documents into the PDF/A archive files. PDF/A-3 files may be used to carry XML files which include the billing data for e-invoicing solutions. In this way, the PDF/A-3 file holds both a visual representation of the invoice (in the PDF part of the file), and a part that may be read and processed directly by e-billing/e-invoicing (ZUGFeRD) applications.

  • Basic Functionality: render, display pages, zoom, navigation, display modes
  • Search in documents, including advanced search
  • Links, bookmarks (table of contents, structure), named destinations
  • Interactive end user tools, magnifier and snapshot; Tracker tool (including insertion of notes, stamps, water marks); rectangle tool (insertion of fields, hyperlinks etc.), text selection and text marking, text boxes, stylus, eraser, vector forms
  • Management of PDF annotations
  • Dynamic notes: text-mark up, annotations, stylus, forms
  • Fill in and save forms
  • Digital signatures: validate, sign, timestamp
  • Media Player API
PDF Xpansion SDK supports all types of annotations (comments) which are defined in the PDF specification, including:

  • Text marks, notes, stamps, water marks
  • Text box and marking, stylus, eraser, forms (lines, square, circle, etc.)
  • Media- and 3D-annotations
  • Forms and digital signatures
  • Annexes as annotations, feedback & status displays for annotations
  • Interactive tools to add all type of annotations
Generation 13 of the SDK provides several API sets with similar structure and functionality:

  • Windows – applications and services written in C++ like the classic Windows x86/x64 programs
  • DotNET – .NET Framework applications
  • COM platform (Embarcadero environment and OLE Automation languages)
  • UWP – applications for all Windows 10 devices
  • Windows Store applications for Windows 8.1

Please read more about the system requirements for the applications developed with PDF Xpansion SDK.

The PDF Xpansion SDK functionality consists of three main parts:

  • PDF functionality: creating and processing of PDF documents. Covert PDF documents from other formats, open, save, encode, and digitally sign PDF documents. Manage document pages, create and edit annotations, convert, merge and split files, create and process forms and much more. An especially important functionality: the creation of new documents and editing existing ones with the PDF editor. PDF/A-1, -2, -3 are supported as well.
  • XPS functionality: processing of XPS documents. For the XPS format, there are many functions available as well: first of all, the conversion of XPS to PDF and vice versa. You can also change the document structure, render pages and much more.
  • Viewer functionality: The viewer is a window or control (depending the development platform) that displays PDF, XPS or other documents and processes for end user activity (touchscreen, mouse and keyboard input). The viewer supports different layouts of displayed document, free zooming and several fit modes.Interactive tools for annotations and forms processing, page content editor tool are available as well.
  • Other functionality: e-invoicing (ZUGFeRD documents), JavaScript support, text recognition (OCR), XFA forms (preview, print, access form data), etc.
