smartcrop.rs

Smartcrop is a content-aware image cropping library that attempts to find the best crop for a given image and aspect ratio.

The original Javascript implementation smartcrop.js was developed by Jonas Wagner.

This is a fork of https://github.com/bekh6ex/smartcrop.rs by Bekh-Ivanov Aleksey, since the original project is unmaintained and does not support newer versions of the image crate.

How to use

let height = 1920;
let width = 1080;

let res = smartcrop::find_best_crop(
    &image,
    NonZeroU32::new(height).unwrap(),
    NonZeroU32::new(width).unwrap()
).expect("Failed to find crop");
let c = res.crop;
let cropped = image.crop_imm(c.x, c.y, c.width, c.height);
let scaled = cropped.resize(width, height, image::imageops::FilterType::Lanczos3);
