A JavaFX library that allows Java2D code (Graphics2D) to be used to draw to a Canvas node.
Version 2.1.4, 12 February 2023.
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:
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.

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>
You can build FXGraphics2D
from sources using Maven:
mvn clean install
FXGraphics2D is being tested using Graphics2D Tester and produces the output shown below. There are several areas that still need work:
