FXGraphics2D

Version 2.1.4, 12 February 2023.

Overview

FXGraphics2D is an implementation of Java's Graphics2D API that targets the JavaFX Canvas. It makes it possible to reuse existing Java2D code in a JavaFX application. The following example is generated by JFreeChart-FX:

Background

The code has been developed for the use of Orson Charts (https://github.com/jfree/orson-charts/) and JFreeChart (http://www.jfree.org/jfreechart). Numerous demos can be found in the JFree-FXDemos project page at GitHub.

FXGraphics2D requires JDK 11 or later and is licensed under the terms of a (three clause) BSD-style license.

Include

To include FXGraphics2D in your own project, add the following Maven dependency:

<dependency>
    <groupId>org.jfree</groupId>
    <artifactId>org.jfree.fxgraphics2d</artifactId>
    <version>2.1.4</version>
</dependency>

Build

You can build FXGraphics2D from sources using Maven:

mvn clean install

Testing

FXGraphics2D is being tested using Graphics2D Tester and produces the output shown below. There are several areas that still need work:

• the compositing rules in AlphaComposite cannot be mapped 100% to JavaFX equivalents
• font metrics are approximated
• image drawing with clipping shows a strange greying out effect
