Position x and y of each non-transparent pixel of the active layer

[Elwissan]

Hi

I need to know the position x and y of each non-transparent pixel of the active layer.

Example:

Image applied at 200%. Size: W 525px, H 270px, 72dpi.

Each square represents one pixel.

return [x,y]; //~ Left, Top
//~ That is
myArrayPositions.push([x,y]);
//~ myArrayPositions.push([2,0]);
//~ myArrayPositions.push([5,1]);
//~ myArrayPositions.push([11,2]);
//~ myArrayPositions.push([2,4]);
//~ myArrayPositions.push([3,4]);

But I have difficulties.

To this day, everything I've tried has not worked or is too slow to become feasible.

Working with Windows / Photoshop CS6 / VBS / JSX

Thanks!

app.preferences.rulerUnits = Units.PIXELS;
var doc0 = app.activeDocument;
var w = doc0.width.value;
var h = doc0.height.value;
app.activeDocument.quickMaskMode = false;
selection_from_layer();
app.activeDocument.quickMaskMode = true;
var d = new ActionDescriptor();
d.putClass(stringIDToTypeID("new"), stringIDToTypeID("document"));
var r = new ActionReference();
r.putEnumerated(stringIDToTypeID("channel"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
d.putReference(stringIDToTypeID("using"), r);
executeAction(stringIDToTypeID("make"), d, DialogModes.NO);
var file = new File(Folder.temp.fsName + "\\" + "pixels.raw");
var d = new ActionDescriptor();
var d1 = new ActionDescriptor();
d1.putString(stringIDToTypeID("fileCreator"), "8BIM");
d.putObject(stringIDToTypeID("as"), stringIDToTypeID("rawFormat"), d1);
d.putPath(stringIDToTypeID("in"), file);

doc0.selection.deselect();
file.open("r");
file.encoding = "BINARY";
var data = file.read();
file.close();
file.remove();
var result = new Array();
for (x = 0; x < w; x++)
    for (y = 0; y < h; y++)
        if (data.charCodeAt(x+w*y) != 255) result.push([x,y]);
alert(result.toSource())
function selection_from_layer()

        }   
    catch (e) { throw(e); }   
    }
