PDF Xpansion SDK - the kernel library of PDF Xpansion technology. The library provides for applications an ability to use digital documents in PDF format, incl. PDF/A, which is nowadays de facto the standard for digital documents. The library is built in a special way to satisfy the requirements of almost any category of third-party developers or systems integrators. The PDF SDK consists of the following libraries: - PDF Direct: create and save PDF files, add new pages over "draw" technique (or print procedure) - PDF Quick View: load, read, display and print - PDF Quick Viewer: ready PDF Reader with already implemented user functionality, also available as ActiveX- and .NET-Control - PDF Quick Converter: import images, text and HTML files in PDF documents; export text from a PDF document, export PDF pages as images - PDF/A Direct: create and save PDF/A files - PDF/A Converter: converting of the existing PDF documents to PDF/A-1a, PDF/A-1b - PDF Builder: create new pages of a PDF document and fill page content objects - PDF Rich Edit: edit pages a PDF document through the modifying of the page content objects Several extensions increase the kernel functionality, for example: Bookmarks, Watermarks, Comments, Forms, merge documents. PDF SDK can be used on the platform of any modern version of Windows: Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows 2008, Windows 7. 32-bit and 64-bit versions are also supported. PDF library is completely independent and it does not require any specific system components or any software that is not included in the operating system. It will not be an overstatement to say that PDF SDK will satisfy the needs of almost every developer regardless of the development framework that they use. The core of the technology is written on C++, thus, PDF SDK provides C++ API.
