## Example

### Normal Usage

```rust
use qrqrpar::{QrCode, QrStyle};

fn main() {
    // Encode some data into bits.
    let code = QrCode::rmqr("Hello, rmqr!").unwrap();

    // Define style
    let style = QrStyle::default();

    // Render the bits into an image and save it.
    code.save_png("rmqr.png", &style).unwrap();
}
``` 

Generates this image:

### With Options

```rust
use qrqrpar::{EcLevel, QrCode, QrShape, QrStyle, RmqrStrategy};

fn main() {
    // Encode some data into bits with the desired ECC level and strategy.
    let code = QrCode::rmqr_with_options(
        "驫驫驫驫驫驫驫驫驫驫驫驫驫驫",
        EcLevel::H,
        RmqrStrategy::Width,
    )
    .unwrap();

    // Specify the desired output size and style.
    let style = QrStyle::new("#0000cc", "#ffffcc", QrShape::Round, 720, 2.0);

    // Render the bits into an image and save it.
    code.save_svg("rmqr_round.svg", &style).unwrap();
}
```

### Normal QR Code


```rust
use qrqrpar::{QrCode, QrStyle};

fn main() {
    let code = QrCode::new("Normal QR code").unwrap();

    // Specify the desired output color.
    let style = QrStyle {
        background_color: String::from("rgba(0,0,0,0)"),
        ..Default::default()
    };

    // Render the bits into an image and save it.
    code.save_png("normal_qr.png", &style).unwrap();
}
```
