captcha = "*"In your source file do:
extern crate captcha;
use captcha::Captcha;
use captcha::filters::Noise;
use std::path::Path;
fn main() {
Captcha::new()
.add_chars(5)
.apply_filter(Noise::new(0.1))
.view(220, 120)
.save(Path::new("/tmp/captcha.png"))
.expect("save failed");
}git clone [email protected]:daniel-e/captcha.git
