PDF Clown is a free and open source library that implements the Portable Document Format (PDF) specification in multiple languages (Java 1.5 and C# 2.0).

PDF Clown is a software library. Its intended audience is therefore primarily software developers. Nonetheless, future efforts may result in GUI-based utilities for performing common tasks (e.g. PDF files merging/splitting) accessible to casual users too.

Here are some key features of "PDF Clown":

· PDF generator: PDF Clown can create new PDF files
· PDF reader: PDF Clown can access existing PDF files
· PDF editor: PDF Clown can manipulate existing PDF files

Requirements:

· Java
