Example

The following example turns an image to gray scale (maintaining the alpha), then upscales it, and blurs it.

extern crate picto;
use picto::{read, write};
use picto::color::{Rgba, Lumaa};
use picto::processing::prelude::*;

use std::env;

fn main() {
  write::to_path(env::args().nth(2).unwrap(),
    &read::from_path::<u8, Rgba, _>(env::args().nth(1).unwrap()).unwrap()
      .convert::<u8, Lumaa>()
      .scale_by::<scaler::Cubic, u8, Rgba>(2.0)
      .blur::<u8, Rgba>(4.0)).unwrap();
}
