Removal of Groups with black masks

[Tsu-tey]

You guys are awesome! I will update to this script, just to make sure.

I feel like I ask too much right now, but is it possible to include removal of Groups with black mask?

I hope it isn't a pain in the a**.

// important, the active layer does not to be a group itself (active group mask allowed). This is due to a bug that cannot be fixed so far. Someone at Adobe decided that calculations and applyimage command should not be available in such a situation. Morons ... 


var inv = false; // depends on channels settings. true = masked areas, false = selected areas. check what you have when manually adding new alpha channel.


var r = new ActionReference();
r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("count"));
r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
var count = executeActionGet(r).getInteger(stringIDToTypeID("count"));


var n = 0; 
try { app.activeDocument.backgroundLayer; } catch(e) { n = 1; ++count; }


var r_idx = new ActionReference();
var do_it = false;

for (var i = count-1; i >= n; i--)
    {
    var r = new ActionReference();
    r.putIndex(stringIDToTypeID("layer"), i);
    if (executeActionGet(r).getInteger(stringIDToTypeID("layerKind")) != 7) continue; 

    var d = new ActionDescriptor();
    var r = new ActionReference();
    r.putProperty(stringIDToTypeID("channel"), stringIDToTypeID("selection"));
    d.putReference(stringIDToTypeID("null"), r);
    var d1 = new ActionDescriptor();
    var r1 = new ActionReference();
    r1.putEnumerated(stringIDToTypeID("channel"), stringIDToTypeID("channel"), stringIDToTypeID("mask"));
    r1.putIndex(stringIDToTypeID("layer"), i);
    d1.putBoolean(stringIDToTypeID("invert"), inv);
    d1.putReference(stringIDToTypeID("to"), r1);
    d1.putEnumerated(stringIDToTypeID("calculation"), stringIDToTypeID("calculationType"), stringIDToTypeID("normal"));
    var r2 = new ActionReference();
    r2.putEnumerated(stringIDToTypeID("channel"), stringIDToTypeID("channel"), stringIDToTypeID("mask"));
    r2.putIndex(stringIDToTypeID("layer"), i);
    d1.putReference(stringIDToTypeID("source2"), r2);
    d1.putBoolean(stringIDToTypeID("invertSource2"), inv);
    d.putObject(stringIDToTypeID("to"), stringIDToTypeID("calculation"), d1);
    executeAction(stringIDToTypeID("set"), d, DialogModes.NO);


    var r = new ActionReference();
    r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("selection"));
    r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));

    if (!executeActionGet(r).hasKey(stringIDToTypeID("selection")))  { r_idx.putIndex(stringIDToTypeID("layer"), i); do_it = true; }
    }

app.activeDocument.selection.deselect();

if (do_it)
    {
    var d = new ActionDescriptor();
    d.putReference(stringIDToTypeID("null"), r_idx);
    executeAction(stringIDToTypeID("delete"), d, DialogModes.NO);
    }

alert("done");

sTT = stringIDToTypeID; (function(v) {
	var lrs = [].slice.call(v); while(lrs.length) {
		(ref = new ActionReference()).putIdentifier
		(sTT('layer'), id = (theCurrentLayerSet = lrs.shift()).id);
		((dsc = executeActionGet(ref)).getBoolean(sTT('hasUserMask')) &&
		(ref.putIdentifier(sTT('layer'), id), dsc.putReference(sTT('null'), ref),
		executeAction(sTT('select'), dsc)) && ((ref1 = new ActionReference())
		.putProperty(channel = sTT('channel'), selection = sTT('selection')),
		dsc.putReference(sTT('null'), ref1), (ref2 = new ActionReference())
		.putEnumerated(channel, channel, sTT('mask')),
		dsc.putReference(sTT('to'), ref2),
		executeAction(sTT('set'), dsc))

		&& ((ref = new ActionReference()).putProperty(sTT('property'), selection),
		ref.putEnumerated(sTT('document'), sTT('ordinal'), sTT('targetEnum')),

	}
	aD.selection.deselect()
})((aD = activeDocument).layerSets)

What about the other script I wrote. It does what you described in starting post. Did you try it:
Help with script that select Layers based on string then move selected layers to specific folder.

Removes all masks in groups. It is right?

[Kukurykus]

I noticed it myself and corrected the script meantime 😉

[r-bin]

Now removes black masks. Is that what the author asked for?

[Kukurykus]

Right - I understood he wants black masks from groups.

Actually I forgot during writing what was the gaol 😕 loll

I edited a little the script and now it does what it should 🙂

[Tsu-tey]

Thank you for you commitment!
