Overview
--------
**SWTGraphics2D** is an implementation of Java2D's `Graphics2D` API that targets an Eclipse Standard Widget Toolkit (SWT) graphics context, allowing the use of Java2D code in SWT applications.  

Background
----------
The code was originally developed as part of the [JFreeChart](http://github.com/jfree/jfreechart) project .  It is now a standalone project.

Include
-------
**SWTGraphics2D** is published to the Central Repository.  You can include it in your projects with the following dependency:

    <dependency>
      <groupId>org.jfree</groupId>
      <artifactId>swtgraphics2d</artifactId>
      <version>1.1.0</version>
    </dependency>

Testing
-------
**SWTGraphics2D** is being tested using [Graphics2D Tester](https://github.com/jfree/graphics2d-tester) and produces the output shown below (using the snapshot version of `SWTGraphics2D`)

Due to limitations of the SWT Graphics API, there are several Java2D features that cannot be supported:

- the Porter-Duff compositing rules in `AlphaComposite`
- multi-linear and radial gradient paints.
