    With script
        .AddCode "function add(a,b) {return 'result from '+a+' + '+b+' is ' +(a+b);}"
        result = .Run("add", 1, 2)

        // block sizes (width and height) in pixels
        var bw = 2;
        var bh = 2;

        // create canvas element based on number of columns and rows in barcode
        var canvas = document.createElement('canvas');
        canvas.width = bw * barcode['num_cols'];
        canvas.height = bh * barcode['num_rows'];
        document.getElementById('barcode').appendChild(canvas);
