This crates exports functions and types that can be used to search for QR-Codes in images and decode them.
The most basic usage is shown below:
use image; use rqrr; let img = image::open("tests/data/github.gif")?.to_luma(); // Prepare for detection let mut img = rqrr::PreparedImage::prepare(img); // Search for grids, without decoding let grids = img.detect_grids(); assert_eq!(grids.len(), 1); // Decode the grid let (meta, content) = grids[0].decode()?; assert_eq!(meta.ecc_level, 0); assert_eq!(content, "https://github.com/WanzenBug/rqrr");
