The new Generation of Developer Libraries with new Functions & Support for E-Invoicing


The 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. It allows you to use PDF functionality in Windows desktop (PC) applications as well as in your Windows Store / Windows Phone Store apps.

Version 12 of the PDF Xpansion SDK is still available.


New Features in Version 13


  • View and print eBook files (EPUB, MOBI, FB2)
  • eBooks (EPUB, MOBI, FB2) can be converted to PDF
  • Undo operation for content editor and mostly used PDF functions

Further improved functionality of:


  • Conversion of HTML files and web pages to PDF
  • The conversion of Word and Excel files to PDF
  • The support of JavaScript within the PDF documents
  • Processing of PDF forms
  • Rendering (displaying and printing) of PDF documents

Core Funktions


  • 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: Basic, Comfort, Extended.)
  • 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)

PDF/A


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.


PDF Editor


  • Create new page content in PDF-files
  • Determine page content, texts, images or vectors for free editing
  • Create and edit form fields
  • Site Management: enlarge the site, rotate, add, delete etc.
  • Split or merge documents, arrange the sites or the content

  • 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

Annotations


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

Development Platforms


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

SDK Structure


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.
