Module qrcode::canvas

The canvas module puts raw bits into the QR code canvas.

use qrcode::types::{Version, EcLevel};
use qrcode::canvas::{Canvas, MaskPattern};

let mut c = Canvas::new(Version::Normal(1), EcLevel::L);
c.draw_all_functional_patterns();
c.draw_data(b"data_here", b"ec_code_here");
c.apply_mask(MaskPattern::Checkerboard);
let bools = c.to_bools();

Structs

• Canvas
  Canvas is an intermediate helper structure to render error-corrected data into a QR code.

Enums

• MaskPattern
  The mask patterns. Since QR code and Micro QR code do not use the same pattern number, we name them according to their shape instead of the number.
• Module
  The color of a module (pixel) in the QR code.

Functions

• is_functional
  Gets whether the module at the given coordinates represents a functional module.
