Overview

PDFlib makes PDF generation possible without wading through the PDF specification. While PDFlib tries to hide technical PDF details from the user, a general understanding of PDF is useful. In order to make the best use of PDFlib, application programmers should ideally be familiar with the basic graphics model of PostScript (and therefore PDF). However, a reasonably experienced application programmer who has dealt with any graphics API for screen display or printing shouldn’t have much trouble adapting to the PDFlib API as described in the PDFlib manual.

Server Deployment: PDFlib is thread-safe, i.e. it can safely be used in multi-threaded server applications. The COM edition is both-threaded for improved performance. C or C++ library clients can install their own memory management and error handling routines. PDFlib's memory management has been rigorously engineered and tested for memory leaks in order to guarantee 24-hour deployment without any shutdown periods.

Features

• PDFlib is a library which allows you to generate files in Adobe’s Portable Document Format (PDF). PDFlib acts as a backend to your own programs
• PDFlib doesn't make use of third-party software for generating PDF, nor does it require any other tools. PDFlib is available for all major operating environments and development environments
• PDFlib offers many useful functions for creating text, graphics, images, and hypertext elements in PDF
• A PDFlib program can be used for dynamically generating PDF – reflecting user input or dynamic data retrieved from web or database servers. The optional add-on PDF Import Library (PDI) can be used to integrate pages from existing PDF documents into the generated output. With the PDFlib Personalization Server (PPS) as further add-on, server side personalization of PDF files becomes possible
• With the programmer only being responsible for producing the data from whatever source, PDFlib takes the task of generating the PDF code which visually represents the data
• PDFlib can generate PDF data directly in memory (instead of on file), resulting in better performance and avoiding the need for temporary files, thus being the fastest PDF-generating method

Annual Support is available to purchase with new product licenses or to renew an existing support contract:
The support contract is for 12 months and includes:

• Technical support with short response times
• All minor (maintenance) and major (functional) updates
• Early availability of bug fixes
