PDF Library
Big Faceless Organization
$850.00/one-time/ user A PDF library to create, edit, display, and print Acrobat PDF documents. The PDF API is small and fast. It is easy to integrate into your projects and is written entirely in Java. The API has been designed so you don't need to know the PDF specification in order to create PDFs. We hide as much of the gory details as possible but still give you almost complete control over the PDF itself. Where possible we re-use standard Java classes - for example the pages are stored in a java.util.List, which can be manipulated any way you like (so moving pages from one document to another is a breeze). This means an API which is smaller and easier to remember. The Viewer Extension allows PDFs to be parsed and converted to bitmaps for display, to be saved as a bitmap image (e.g TIFF) or for printing. Although Java 5 theoretically supports printing PDFs out of the box, results are often poor and support for features like annotations, encrypted documents etc. is incomplete. Our PDF library fills this gap, giving consistent results for all PDFs. -
