# seamcarving

A rust library for
**content-aware image resizing** using [seam carving](https://en.wikipedia.org/wiki/Seam_carving).

## How to use

Open an image using the [**image** crate](https://crates.io/crates/image),
then use the `resize` function from this create to create a smaller version
of the image, while preserving its contents.

```rust
let img = image::open("input.jpg")?;
let (width, height) = img.dimensions();
let resized = seamcarving::resize(&img, width/2, height);
resized.save("resized.jpg")?;
```
