Hi, i write a code for make a QR code.

First i write it using selection... this is the relevant part:

  for (var iy = 0; iy < riga; iy++){ //riga is the number of modules in a row of the QR

       for (var ix = 0; ix < riga; ix++){ //QR is a square, same modules in a columns

            if (qrcode[ix][iy] == true){  //qrcode is an array of an array... a matrix where the value is true if the square in that position is black

                 var _x = ix * s;     //s is the size of qr code little squares unit, in this case its value is 8 pixel

                 var _y = iy * s;

                 selectedRegion =

                 [

                 [_x + 0 + x, _y + 0 + y],

                 [_x + 0 + x, _y + s + y],

                 [_x + s + x, _y + s + y],

                 [_x + s + x, _y + 0 + y]

                 ];

                 //Add to selection

                 mydoc.selection.select(selectedRegion, SelectionType.EXTEND);

            }

       }

  }

  //Fill selection with solid color

  var squareColor = new RGBColor;

  squareColor.hexValue = "000000";

  mydoc.selection.fill(squareColor);

  mydoc.selection.deselect();

This work, but is very slow because it must create a selection square for more than 3000 times.

Now i'm trying to use path and crate all the path before drawing it in the document.

This is the code, but no work

/*
var lineArray = [];
var arrn = 0

    for (iy = 0; iy < riga; iy++) {

for (var ix = 0; ix < riga; ix++){
if (qrcode[ix][iy] == true){
var _x = ix * s;
var _y = iy * s;
for (i=0;i<4;i++){
//alert(ix)
//alert(i)
lineArray[arrn+i] = new PathPointInfo;
lineArray[arrn+i].kind = PointKind.CORNERPOINT;
switch(i){
case 0: lineArray[arrn+i].anchor = [ parseInt(x + _x) , parseInt(y + _y)];
break;
case 1: lineArray[arrn+i].anchor = [ parseInt(x + _x ), parseInt(y + _y + s)];
break;
case 2: lineArray[arrn+i].anchor = [ parseInt(x + _x + s) , parseInt(y + _y + s)];
break;
case 3: lineArray[arrn+i].anchor = [ parseInt(x + _x + s) , parseInt(y + _y)];
break;
}
//alert(lineArray[arrn+i].anchor)
lineArray[arrn+i].leftDirection = lineArray[arrn+i].anchor;
lineArray[arrn+i].rightDirection = lineArray[arrn+i].anchor;
}
//alert(arrn)
arrn = arrn + 4;
}
}
    }

    var lineSubPathArray = new SubPathInfo();

    lineSubPathArray.closed = true;

    lineSubPathArray.operation = ShapeOperation.SHAPEADD;

    lineSubPathArray.entireSubPath = lineArray;

    var myPathItem = mydoc.pathItems.add("myPath", [lineSubPathArray]);*/

the error is parameter not valid in the last row. I know that it is incomplete because diagonal lines from a square to another...

i want only know if is possible or you have any idea to make this qr code generation more fast.. whit any method

Sorry for my poor english!

This work fine

Thanks this works great!
How can I change the dimensions and resolution of the file?
Simply changing the numbers in app.documents.add doesn't seem to do the trick.

var mydoc = app.documents.add( 600, 600, 72, "tmp", NewDocumentMode.RGB, DocumentFill.WHITE );

Only change the dimensions (not the resolution) e.g:

 

var mydoc = app.documents.add(1200, 1200, 72, "tmp", NewDocumentMode.RGB, DocumentFill.WHITE );

 

And at the end of the script change the resolution e.g.:

 

mydoc.resizeImage(undefined, undefined, 600, ResampleMethod.NONE);
