JDK 21 - Image Performance Improvements
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.

The Ancient Secrets of Computer Vision
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!

Good Open Source Repositories that Accepts New Contributors
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.

JavaFX .jar (from clojure) won't find "glass" when run via `java -jar`
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."

Feedback Requested on Updated BoofCV QR Code Tutorial
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.

Software to turn black and white image into plottable SVG?
A lot of resources can be found here: https://drawingbots.net/resources VPype is one that comes to mind... as well as https://github.com/SonarSonic/DrawingBotV3 which I've used with good success.

- Is it possible to draw my face with a plotter?
- Some Spitfire drawings I did over 3.5 years ago. One source file processed 3 ways.

After the test phase, here is the first 'real' drawing made by my Polargraph. 25000 lines for 3 hours of drawing. Format 18x18cm. The machine can go up to A2 size I'm quite satisfied with the result. If you want more information about the polargaph : https://www.thingiverse.com/thing:5136394
Thanks ! I use DrawingBot V3 for production https://github.com/SonarSonic/DrawingBotV3 Good idea for Z stepper.

RIP Mister the Cat - I miss you every single day!
It's maybe a bit easier than you think! I started with a photo, edited it with photoshop, then processed it using the DrawingBot software Thanks to github user SonarSonic. It took me several attempts to get the final, but with some experimenting with the DrawingBot settings, going back and forth to photoshop, then back to inkscape, I split the image into 3 layers for the different colors and I'm pretty happy with the result.
