Sharpened Bilinear

Sharpened Bilinear is an image resizing library and command-line tool that uses a modified bilinear interpolation algorithm to produce sharp, accurate results. It supports resizing with premultiplied alpha and operates in linear space to avoid brightness distortion.

Installation

To use Sharpened Bilinear as a command-line tool, install it with Cargo:

cargo install sharpened_bilinear

To use Sharpened Bilinear as a library, add the following to your Cargo.toml:

[dependencies]
sharpened_bilinear = "1.0.0"

Usage

Command-line tool

USAGE: sharpened_bilinear <INPUT> [OPTIONS]

ARGS:
  <INPUT>         Input file path (required)

OPTIONS:
  --output PATH   Output file path
  --factor NUMBER Scale factor
  --width  NUMBER Output image width in pixels
  --height NUMBER Output image height in pixels

Defaults:
  sharpened_bilinear <INPUT> -o <INPUT>_resized.png -f 1.0

If only one of the keys '-w' or '-h' is given, the
the second dimension preserves the aspect ratio or
determined from the '-f' key if factor given.

Library

let input_image = image::open("input.png").unwrap();
let resized_image: image::DynamicImage =
    sharpened_bilinear::resize(&input_image, width, height).into();
resized_image.save("output.png").unwrap();
