SWTGraphics2D

Version 1.1.0 - 29 August 2021.

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 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 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.
