How to use JavaScript move layer in Photoshop using the relative coordinates

Question

I'm just starting to work with JS to Photoshop. I need to align 2 or more layers between as? for example- on top. Each layer has a mask that is smaller than the image. Using Photoshop menu I can aligns only images, without their masks.I want to align images on their masks - visible through the mask to the image on the same level. Thanks !

mmIf you want to transform layers (or layer masks) use these three functions. You didn't mention what version of PS you are using.

• selectmask - selects the layer mask in the layer as active
• linkUnlinkLayermask - will link or unlink the layer mask to it's layer
• transformLayerLayer - offset layer (or layermask) by a number of pixels

You should be able to manipulate the layers and align them as you need them.

//pref pixels
app.preferences.rulerUnits = Units.PIXELS;

var deltaX = 0
var deltaY = 20

selectMask("Layer 1")
linkUnlinkLayermask(false)
transformLayer(deltaX, deltaY)

function transformLayer(moveX, moveY)
{
    var id442 = charIDToTypeID( "Trnf" );
    var desc93 = new ActionDescriptor();
    var id443 = charIDToTypeID( "null" );
    var ref64 = new ActionReference();
    var id444 = charIDToTypeID( "Lyr " );
    var id445 = charIDToTypeID( "Ordn" );
    var id446 = charIDToTypeID( "Trgt" );
    ref64.putEnumerated( id444, id445, id446 );
    desc93.putReference( id443, ref64 );
    var id447 = charIDToTypeID( "FTcs" );
    var id448 = charIDToTypeID( "QCSt" );
    var id449 = charIDToTypeID( "Qcsa" );
    desc93.putEnumerated( id447, id448, id449 );
    var id450 = charIDToTypeID( "Ofst" );
    var desc94 = new ActionDescriptor();
    var id451 = charIDToTypeID( "Hrzn" );
    var id452 = charIDToTypeID( "#Pxl" );
    desc94.putUnitDouble( id451, id452, deltaX );
    var id453 = charIDToTypeID( "Vrtc" );
    var id454 = charIDToTypeID( "#Pxl" );
    desc94.putUnitDouble( id453, id454, deltaY );
    var id455 = charIDToTypeID( "Ofst" );
    desc93.putObject( id450, id455, desc94 );
    executeAction( id442, desc93, DialogModes.NO );
}

function selectMask(LayerName)
{
    var id2380 = charIDToTypeID( "slct" );
    var desc475 = new ActionDescriptor();
    var id2381 = charIDToTypeID( "null" );

    ref352.putEnumerated( id2382, id2383, id2384 );
    var id2385 = charIDToTypeID( "Lyr " );
    ref352.putName( id2385, LayerName );
    desc475.putReference( id2381, ref352 );
    var id2386 = charIDToTypeID( "MkVs" );
    desc475.putBoolean( id2386, false );
    executeAction( id2380, desc475, DialogModes.NO );
