PDF Clown

Abstract library devoted to the manipulation of PDF files, implemented on multiple platforms
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.

Main 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 of PDF Clown:

Java

What's New in This Release:

[add] Actions (see documents.interaction.actions.*)

[add] Annotations (see documents.interaction.annotations.*)

[add] Acroform (see documents.interaction.forms.*)

[add] Page-level navigation (see documents.navigation.page.*)

documents.contents.objects.*)

[fix:1909704] Symptom: case-insensitive programming languages experience namespace collision.

Cause: some classes (ColorSpaces, Fonts, XObjects) had names equivalent to subnamespaces

(colorSpaces, fonts, xObjects). See: documents.contents.ColorSpaceResources/

FontResources/XObjectResources: namespace collision is now resolved.

[fix:0.0.6:1:SC] Symptom: after a file-system file is opened it keeps being locked undefinitely.

Cause: lack of explicit disposal. See: files.File.close()/.Dispose(): file lock is now appropriately

released on object disposal.
