Question

Or how to identify a camera in actionscript 3?

Answer 1

Here is an example...
var originalUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
var doc = activeDocument;
var Colour1 = GetHexColour(eyeDropperRGB(1,doc.height-1));
var Colour2 = GetHexColour(eyeDropperRGB(20,doc.height-5));
var Colour3 = GetHexColour(eyeDropperRGB(40,doc.height-14));
alert("Colour 1 = " +Colour1 + "\rColour 2 = " +Colour2 + "\rColour 3 = " +Colour3);
var decColour = eyeDropperRGB(40,doc.height-14);
alert("Red = " +decColour[0] + "\rGreen = " +decColour[1] + "\rBlue = " +decColour[2]);
app.preferences.rulerUnits = originalUnits;
function GetHexColour(reqHex){
var out='';
for(No in colours = reqHex){
out = out.concat(zeroPad(d2h(reqHex[No]),2));
return out;
function eyeDropperRGB(x,y) {
var x2 = x + 1;
var y2 = y + 1;
var out = new Array(3);
activeDocument.selection.select([[x,y], [x2,y], [x2,y2], [x, y2]], SelectionType.REPLACE, 0, false);
for(ch in list = ["Red", "Green", "Blue"]) {
histogram = activeDocument.channels[list[ch]].histogram;
  for (i = 0; i <= 255; i++) {
   if (histogram[i]) {
    out[ch] = i;
    break;
  return out; 
function d2h(d) {return d.toString(16);}
function zeroPad(n, s) {
   n = n.toString();
   while (n.length < s)  n = '0' + n;
   return n;
