Function rqrr::find_and_decode_from_image

pub fn find_and_decode_from_image(img: &DynamicImage) -> Vec<Code>

Given a image object, locate all codes found in it

This is a convenient wrapper if you use the image crate already. The only requirement for the image is that the 'black' parts of a QR code are 'dark', 'white' parts 'bright'.

Example

use image;
use rqrr;

let img = image::open("tests/data/github.gif").unwrap();
let codes = rqrr::find_and_decode_from_image(&img);
assert_eq!(codes.len(), 1);
assert_eq!(codes[0].val, "https://github.com/WanzenBug/rqrr");
