im trying to align a layer to top and left of another layer, i found a code that does the align but the selection part i changed isn't working, how do i set selection to a specific layer i have?
thanks.
 

 

        Doc.selection.select(ImgLocation);
        Doc.activeLayer = layer;

        var desc = new ActionDescriptor();
        var ref = new ActionReference();
        ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
        desc.putReference(charIDToTypeID("null"), ref);
        desc.putEnumerated(charIDToTypeID("Usng"), charIDToTypeID("ADSt"), charIDToTypeID('AdLf'));
        desc.putEnumerated(charIDToTypeID("Usng"), charIDToTypeID("ADSt"), charIDToTypeID('AdTp'));
        try {
            executeAction(charIDToTypeID("Algn"), desc, DialogModes.NO);
        } catch (e) {}

        Doc.selection.deselect();

A couple of ways:

 

1) Using the ScriptingListener plugin to record the Ctrl/Cmd click on the layer icon or the load selection menu command from transparency channel for the layer.

 

2) Get layer bounds coordinates for the layer and use to create a rectangular selection.


P.S. How will you reference the layer? Making it active/selected? By name? By index etc?

 

EDIT: Presuming that the target layer is active you can use the following function call and function to load the layer transparency as a selection:

 

 

layerTransToSel();
function layerTransToSel() {
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};
	var descriptor = new ActionDescriptor();
	var reference = new ActionReference();
	var reference2 = new ActionReference();
	reference.putProperty( s2t( "channel" ), s2t( "selection" ));
	descriptor.putReference( s2t( "null" ), reference );
	reference2.putEnumerated( s2t( "channel" ), s2t( "channel" ), s2t( "transparencyEnum" ));
	descriptor.putReference( s2t( "to" ), reference2 );
	executeAction( s2t( "set" ), descriptor, DialogModes.NO );
}

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible? 

Can the Layer with the target position be unequivocally be identified by name, position, …?
