A fast, simple tool that removes colored backgrounds from images and gives you clean, smooth edges.

Chroma finds the background color on its own and makes it see-through. It uses a blur trick to make the edges look smooth instead of jagged.
./chroma -i ./example-images/ -vBenchmarks run on Arch Linux (AMD Ryzen 9 9950X, 92GB RAM) with libvips 8.17.3, averaged over 3 runs per size:

It looks pretty cool. Does it only work for single-color backgrounds?
Good to see more end-user programs.
