How could I generate a 12x26 2D barcode, for example?

ChuckTerry commented 7 months ago

Here's some sample code for you:

// msg must be a certain length to generate 12x26, that length varies depending on character/number makeup
// rct indicates that you want a rectangle rather than a square
const options = {
  msg :  "Bacon is grand!",
  rct :   1
};

// Generate the SVG
const svg = DATAMatrix(options);

// Append it to something
document.body.appendChild(svg);
