Crate repng 

The PNG encoder that no one asked for.

The abstraction is pretty leaky, but it’s simple enough that you can make cool things without much effort, such as this program, which creates a very blank image.

use repng::Options;

let mut png = Vec::new();

{
    let mut encoder = Options::smallest(480, 360)
        .build(&mut png)
        .unwrap();

    let row = [255; 480 * 4];

    for y in 0..360 {
        encoder.write(&row).unwrap();
    }

    encoder.finish().unwrap();
}

println!("{:?}", png);
