• 2 corner dot styles (dot, square)
• Linear and radial gradient support

• Circle shape support
• Multiple output formats (SVG, PNG, JPEG, WebP)

Example

use qr_code_styling::{QRCodeStyling, OutputFormat};
use qr_code_styling::config::{DotsOptions, Color};
use qr_code_styling::types::DotType;

let qr = QRCodeStyling::builder()
    .data("https://example.com")
    .width(300)
    .height(300)
    .dots_options(DotsOptions::new(DotType::Rounded).with_color(Color::rgb(0, 0, 128)))
    .build()
    .unwrap();

// Render as SVG
let svg = qr.render_svg().unwrap();

// Or save to file
// qr.save("qr.png", OutputFormat::Png).unwrap();
