This project compares the performance of various methods for converting an AWT image to a JavaFX image, including the public utility method SwingFXUtils.toFXImage.
Although some of the methods convert the alpha values incorrectly, they are included in the tests because their conversion is correct when the source AWT image contains no transparent pixels.
The results of running the benchmarks on my systems are published on the website associated with this repository.

This is a Maven project that depends on the Java Microbenchmark Harness. You can build and package the application as the file target/benchmarks.jar with the commands:
$ export JAVA_HOME=$HOME/opt/jdk-14.0.1
$ mvn packageRun a quick test with a command like the following:
$ java -Djava.library.path=$HOME/lib/javafx-sdk-15/lib \
-jar target/benchmarks.jar -f 1 -i 1 -wi 1Run the benchmarks with their default options for a more thorough test:
$ java -Djava.library.path=$HOME/lib/javafx-sdk-15/lib \
-jar target/benchmarks.jarThe -h option prints a description of all benchmark command options:
$ java -jar target/benchmarks.jar -h
