qrcode_gen

Rust QR Code Generic Generator

Example

• example 1 ```rust use image::Luma; use qrcode_gen::{ render::{svg, unicode}, EcLevel, QrCode, Version, };

fn main() { // Image generation // Encode some data into bits. let code = QrCode::new(b"01234567").unwrap();

// Render the bits into an image.
let image = code.render::<Luma<u8>>().build();

// Save the image.
image.save("/tmp/qrcode.png").unwrap();

// String generation
let code = QrCode::new(b"Hello").unwrap();
let string = code
    .render::<char>()
    .quiet_zone(false)
    .module_dimensions(2, 1)
    .build();
println!("{}", string);

// SVG generation
let code = QrCode::with_version(b"123", Version::Normal(5), EcLevel::M).unwrap();
let image = code
    .render()
    .min_dimensions(200, 200)
    .dark_color(svg::Color("#800000"))
    .light_color(svg::Color("#ffff80"))
    .build();
println!("{}", image);

let micro_code = QrCode::with_version(b"123", Version::Micro(1), EcLevel::L).unwrap();
let image = micro_code
    .render()
    .min_dimensions(200, 200)
    .dark_color(svg::Color("#800000"))
    .light_color(svg::Color("#ffff80"))
    .build();
println!("{}", image);

// Unicode string generation
let code = QrCode::new("mow mow").unwrap();
let image = code
    .render::<unicode::Dense1x2>()
    .dark_color(unicode::Dense1x2::Light)
    .light_color(unicode::Dense1x2::Dark)
    .build();
println!("{}", image);

} ```

• example 2 ```rust fn main() { // print qrcode qrcodegen::qrprint("https://rust-lang.org/").unwrap();

  // print qrcode unicode string let string = qrcodegen::qrstring("https://rust-lang.org/").unwrap(); println!("{}", string);

  // print qrcode u8 arr let u8arr = qrcodegen::qrbytes("https://rust-lang.org/").unwrap(); println!("{:?}", u8arr);

  // print qrcode svg String let svg = qrcodegen::qrsvg("https://rust-lang.org/"); println!("{:?}", svg);

  // qrcode image write to /tmp/qrcode.png qrcodegen::qrimage("https://rust-lang.org/", "/tmp/qrcode.png"); }
