Crate resize

Simple resampling library in pure Rust.

Examples

use resize::Pixel::RGB24;
use resize::Type::Lanczos3;
use rgb::RGB8;

// Downscale by 2x.
let (w1, h1) = (640, 480);
let (w2, h2) = (320, 240);
// Don't forget to fill `src` with image data (RGB24).
let src = vec![0;w1*h1*3];
// Destination buffer. Must be mutable.
let mut dst = vec![0;w2*h2*3];
// Create reusable instance.
let mut resizer = resize::new(w1, h1, w2, h2, RGB24, Lanczos3);
// Do resize without heap allocations.
// Might be executed multiple times for different `src` or `dst`.
resizer.resize(&src, &mut dst);
