Apache Batik

Batik is a pure-Java library that can be used to render, generate, and manipulate SVG graphics. IBM supported the project and then donated the code to the Apache Software Foundation, where other companies and teams decided to join efforts.
Batik provides a set of core modules that provide functionality to:

Render and dynamically modify SVG content,
Transcode SVG content to some raster Graphics file formats, such as PNG, JPEG and TIFF,
Transcode Windows Metafiles to SVG,
And manage scripting and user events on SVG documents.

The Batik distribution also contains a ready-to-use SVG browser making use of the above modules.
The name of the library comes from the Batik painting technique.

Status

Batik was long the most conformant existing implementation, with the 1.7 version passing almost 94% of the , which at the time was just a small fraction behind Opera in SVG conformance. Today all the major web browsers support while Batik remains on 1.1.
Version 1.7, made available on January 10, 2008, had an "almost full" implementation of the current state of the sXBL specification, a nearly complete implementation of SVG SMIL features, and some of the late October 2004 working draft, although that version of SVG was dropped for SVG 2.
