qrcode_gen

Rust QR Code Generic Generator

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);

} ```

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

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

// print qrcode u8 arr
let u8_arr = qrcode_gen::qr_bytes("https://rust-lang.org/").unwrap();
println!("{:?}", u8_arr);

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

// qrcode image write to /tmp/qrcode.png
qrcode_gen::qr_image("https://rust-lang.org/", "/tmp/qrcode.png");

}
