Important message in the release notes: "JavaFX 20 is compiled with --release 17 and thus requires JDK 17 or later in order to run. If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the javafx.base module cannot be read."

JavaFX 17 requires at JDK 11 or later (release notes), so the short answer is that you can't do this.

JavaFX has been open-sourced after Oracle dropped it, and it's still in active development (they just released version 19 a month ago, see https://openjfx.io and https://github.com/openjdk/jfx). Also Gluon (https://gluonhq.com) made the toolchain to compile it into native apps for Linux, macOS, Windows, Android & iOS. So with now WebFX compiling it to the web, you get a fully cross-platform UI toolkit that lets you target all major platforms (Desktops, Web, Tablets & Mobiles) from a single Java code base. That's why I think it is interesting, especially for Java developers.

On the JavaFX mailinglist this thrilling message appeared: "Create release notes for JavaFX 19." And yes, they are available now on GitHub! If you want to keep following what’s happening inside the JavaFX community, you can suscribe to it via mail.openjdk.org/mailman/listinfo/openjfx-dev. As with previous releases, the JavaFX community once again succeeded in keeping the 6-months release cycle going on, with a long list of improvements and fixes!

Is there any fast way to get pixel values and pixel coordinate? I had to jump through a lot of hoops to get convert BufferedImages into a format that's useful for image processing it to be a reasonable speed in BoofCV. getRGB() is glacial. At one point I was trying to convince the JDK team to make private data structures public again. Right now it's inconsistent what you have access too.

Apologizes if this post runs afoul of the rules. This is a product we are making that started as an open source project (here).

I will take the opportunity to call out one of my favourite libraries, BoofCV (http://boofcv.org)

It comes with a wonderful demonstration tool that allows you to apply the various included algorithms to images and tweak the parameters in real-time – including the Hough transform. A great tool for helping to understand how these kinds of algorithms work!

Speaking of using the vector api, I see there's a class in boofcv that converts rgb to hsv. I've previously written a simd accelerated version of rgb to hsv using the java vector api. For anybody looking to do a bit of code janitor work, converting the one-off library into something that could be contributed to /u/lessthanoptimal's project might be a worthwhile contribution.

For instance I looked at BoofCV and all I found was : https://github.com/lessthanoptimal/BoofCV/issues/265 " the question now seems to be can you compile the library as native. The answer is probably but someone needs to try it."

It's an all-Java computer vision library, see https://boofcv.org/ and https://github.com/lessthanoptimal/BoofCV

There really is a community for everything on Reddit... Anyways, so I've updated the tutorial on QR Codes in BoofCV. If you're not familiar with it, BoofCV is a computer vision library that also includes a high quality QR Code scanner. Plenty of benchmarks and examples can be found on the website to back that up. Here's a link to the tutorial page and please let me know if it all makes sense. The tutorial focuses on applications which are either command line or have a GUI.
