Vector drawing of QR code using Cairo.
PDF example from the examples/
directory:
rust
let surface = cairo::PdfSurface::new(100.0, 100.0, "example.pdf").unwrap();
let cr = cairo::Context::new(&surface);
qr2cairo::draw(&cr, 100.0, 100.0, "qr2cairo").unwrap();
cr.show_page();
This generates this PDF: example.pdf.
GTK example (note: no GTK required to use qr2cairo):
sh
$ cd examples/gtk ; cargo run
The underlying qrcode crate can create SVGs.
