The program generates a pre-defined set of outputs for any provided subclass of `Graphics2D` that can be compared against a known good result.  The following libraries (as well as others) can be tested this way:\n\n- [JFreeSVG](https://github.com/jfree/jfreesvg)\n- [JFreePDF](https://github.com/jfree/jfreepdf)\n- [FXGraphics2D](https://github.com/jfree/fxgraphics2d)\n- [SkijaGraphics2D](https://github.com/jfree/skijagraphics2d)\n- [SkikoGraphics2D](https://github.com/jfree/skikographics2d)\n\nBy running through the features of `Graphics2D` systematically, this test kit is\nable to highlight areas of weakness in a particular implementation.  The goal is to drive improvements in the\navailable implementations.\n\nTarget Output\n-------------\nThe output of the `Graphics2D` target under test must be manually compared against the expected (\"correct\") output.  The expected output can be generated by running the test program against the `Graphics2D` instance used by Java2D itself \nwhen drawing to a `BufferedImage`.  For example, the following output is generated with Java 20 on MacOS:\n\n![test-image](https://user-images.githubusercontent.com/1835893/232202698-a298b371-0528-4dc3-816e-d6a904469233.png)\n\n\nThird Party Libraries\n---------------------\nThe test kit uses several third party libraries:\n\n- [ZXing](https://github.com/zxing/zxing) - used to create a QR code which is (a) part of the test and (b) provides a link to the `Graphics2D` implementation under test;\n\n- [JFreeChart](https://github.com/jfree/jfreechart) - used to create a sample 2D chart;\n\n- [Orson Charts](https://github.com/jfree/orson-charts) - used to create a sample 3D chart;\n\n- [SteelSeries-Swing](https://github.com/HanSolo/SteelSeries-Swing) - used within the Java Swing UI demo to draw a dial.\n\nLicense\n-------\n**Graphics2D Tester** is free software under the terms of the GNU General Public License version 3 (GPLv3) or later.
