# QRCode

QRCode is a Rust library that provides easy-to-use functions for generating QR code images in PNG or SVG format.

# Usage

To use the QRCode library, add the following to your Cargo.toml file:

[dependencies]
qrcode = "0.8"

Next, add the following to your Rust code:

extern crate image;
extern crate qrcode;

use image::{ImageBuffer, Rgb, RgbImage};
use qrcode::render::svg;
use qrcode::QrCode;

Then, you can create a new QRCode struct with the data you want to encode in the QR code:

let qr_code = QRCode::new(vec![1, 2, 3]);

You can also create a QRCode struct from a string or a vector of bytes:

let qr_code = QRCode::from_string("Hello, world!".to_string());
let qr_code = QRCode::from_bytes(vec![72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33]);

Once you have a QRCode struct, you can use the following methods to generate QR code images:

  • to_qrcode: creates a new QrCode value using the data stored in the QRCode struct
  • to_png: creates a new PNG image of the QR code using the data stored in the QRCode struct
  • to_svg: creates a new SVG image of the QR code using the data stored in the QRCode struct
  • colorize: creates a new PNG image of the QR code using the data stored in the QRCode struct and a given color value to colorize the QR code

# Examples

Here's an example of generating a PNG image of a QR code:

let qr_code = QRCode::new(vec![1, 2, 3]);
let png_image = qr_code.to_png();

And here's an example of generating an SVG image of a QR code:

let qr_code = QRCode::new(vec![1, 2, 3]);
let svg_image = qr_code.to_svg();
