# xBR x2 Filter in Rust

Pixel Art Upscaler

## Checklist

- Add docs
- Add tests
- Add x3 and x4 versions
- Allow resizing: e.g. x2.7 uses x3 and scales down a little

## Examples

`cargo run --example process_image --features="image" --release`

With a small enough resolution it works in realtime too but it has noticable artifacts.
