cleanEdge - Tool to create clean rotation

I came across this tool in my masto timeline: cleanEdge

It creates really clean rotations for sprites. It works really well for everything with clean line but struggle with everything with dithering.

Still, I thought that it might be interesting for people around here.

The source code is also available: cleanEdge, a pixel art upscaling algorithm for clean rotations · GitHub


Wow, pretty decent results! And a free web tool to boot.

I'd rather manually clean up a few stray pixels than draw rotations from scratch!

(Nice upscaling ability too.)

Wow, it is really awesome! I was so impressed that I made a Java port of it. Thank you for sharing.

My port does not produce 100% identical images with the web version (I may have missed some subtleties) but it is pretty close.
