PDF Xpansion SDK 11 – Libraries for the Software Development

Current Generation of PDF Libraries: PDF Xpansion SDK 11

Support for E-Invoicing!

PDF Xpansion SDKThe PDF Xpansion SDK provides a set of APIs that you can use to create high-performance PDF/XPS-able applications and/or software solutions. It gives you wide possibilities to create and edit PDF, PDF/A or XPS documents, display and print them, convert between these two formats, export or/and import to/from other file formats and other potential.

PDF Xpansion SDK 11 is the current version. It allows you to use PDF functionality in Windows desktop (PC) applications as well as in your Windows Store / Windows Phone Store apps.

PDF Xpansion SDK 10 is still available. You find information on this version here.

General Information about the PDF Xpansion SDK

  • Support of Windows 10 and of UWP (Universal Windows Platform) for applications for all Windows 10 devices
  • Page Content Editor Tool in PDF viewer: enables end user to edit content of pages
  • 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: Basic, Comfort, Extended.
  • XMP API: processing metadata in PDFs (read, validate, edit), all standard PDF schemes are supported
  • Display and process dynamic forms (XFA format) for applications created with C++ and .NET: preview in viewer (without filling possibility), printing, API for access to form data (read & fill)

This generation of the SDK provides four 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
  • UWP – applications for all Windows 10 devices
  • Windows Store/Windows Phone Store applications for Windows 8.1

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

For Delphi and/or C++ Builder developers, we provide a wrapper library with COM interface. Please contact us if you need this wrapper.

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, 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 als 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.

The PDF Xpansion SDK 10 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.

Text recognition (OCR) is included in the PDF Xpansion SDK. It is implemented using the Tesseract OCR engine (HP, Google). This feature enables you to recognize text in images in your PDF files and to make your scanned PDF documents searchable. The recognized text can also be exported as plain text from scanned PDF pages or from images that contain text content. See the PDF Xpansion SDK Reference (you find it in PDF SDK package) for more information. You do not need to use the Tesseract engine directly in order to use this feature.
Current version: 3.xx

Number of supported languages: 60

Try it?

In order to test the performance and functions of the PDF Xpansion SDK, you can download the current version of the SDK (trial license). This license allows the use of all SDK functions, but places  a digital demo watermark on the document pages. Examples are offering u the opportunity  to access into the programm. Use the samples given in the SDK for a quick start or read the “Getting Started” chapter in the PDF Xpansion SDK Reference.
