Creating a scannable DATAMATRIX barcode

After you generate your DataMatrix string, just call the `drawDataMatrix` function from the script below. Provide the `ascii` string as the only argument and you'll get a new layer with a "Matrix" group of rectangles representing the 0s and 1s as black and white shapes respectively.

There are some defaults you can adjust like the layer name, group name, and size of the shapes (currently 10 points). The grid of shapes is drawn at the top-left of the artboard but could be changed to easily if you needed it elsewhere.

Try it out and let me know if you have any questions?

// do you datamatrix stuff here

// var dm = new Datamatrix();
// var ascii = dm.getDigit(str, false);

// below I am just using your example from the forum
// it seems the datamatrix package gives you a string separated with new lines
// so I just split the string into an array

var ascii =
  "00000000000000\
01010101010100\
01101001110110\
01001010100000\
01110010111010\

01101110111010\

01100100010100\
01111111111110\
00000000000000";

// call the `drawDataMatrix` function to draw the shapes at the top-left of the artboard
drawDataMatrix(ascii);

function drawDataMatrix(str) {
  // setup defaults
  var defaultLayerName = "Matrix";
  var defaultGroupName = defaultLayerName;
  var defaultRectangleScale = 10;

  // convert the datamatrix string into an array
  var matrix = str.split("\n");

  // setup colors
  var zeroColor = new GrayColor();
  zeroColor.gray = 100; // black
  var oneColor = new GrayColor();
  oneColor.gray = 0; // white

  // setup a layer and a group to hold the art
  var layer, group;
  try {
    layer = app.activeDocument.layers.getByName(defaultLayerName);
    layer.groupItems.removeAll();
  } catch (e) {
    layer = app.activeDocument.layers.add();
    layer.name = defaultLayerName;
  }
  group = layer.groupItems.add();
  group.name = defaultGroupName;

  // iterate over the matrix and draw the rectangles
  var rec;
  for (var y = 0; y < matrix.length; y++) {
    for (var x = 0; x < matrix[y].length; x++) {
      rec = group.pathItems.rectangle(
        -y * defaultRectangleScale,

        defaultRectangleScale
      );
      rec.filled = true;
      rec.stroked = false;
      rec.fillColor = matrix[y][x] === "0" ? zeroColor : oneColor;
