Paste content in alpha channel into layers (ScreenPrint)

[AntonioPacheco]

Hello community, hope eveybody is doing great!

Can anybody help me with my code? I am trying to copy all the info in my alpha channels (spot colors maybe?) to create layer with it's name, I found this one:

https://community.adobe.com/t5/photoshop-ecosystem-discussions/convert-all-alpha-channels-into-layer...

and works good! but it creates things that... I don't know what are they like the ones I point in this screen shot:

The image is in "negative" if I explain myself good, the layers seems to be masked and I need it like a normal layer, I don't know what is that channel I am point which gets the name of the layer I choose, idk.... Here is a code I've been working but I honestly surrender, sorry about the spanish:

var doc = app.activeDocument;
var channelList = [];
if (activeDocument.mode == DocumentMode.RGB) {
alert("the doc is RGB");
for (var i = 2; i < doc.channels.length; i++) {
alert("valor de i es " + i + " conteo en la lista es " + channelList.length);
alert(doc.channels[i].name);
channelList.push(doc.channels[i].name);
alert("conteo en la lista es " + channelList.length);
alert("ahora se va a seleciconar el canal " + channelList[i-2]);
doc.activeChannels = [doc.channels.getByName(channelList[i-2])];
var lyr = app.activeDocument.artLayers.add();
lyr.name = doc.channels[i].name;
app.activeDocument.selection.selectAll();
app.activeDocument.selection.copy();
app.activeDocument.selection.deselect();
app.activeDocument.paste();

}
}
if (activeDocument.mode == DocumentMode.CMYK) {
alert("the doc is  CMYK");
for (var i = 3; i < doc.channels.length; i++) {
alert(doc.channels[i].name);
}
}

I just need to copy all the info in the channels I separated from a picture, whether is CMYK or RGB to layers, please help, thanks.

Could you provide a sample file? 

One work-around might be using »Merge Spot Channel«. 

// determine spot channel colors;
// 2023, use it at your own risk;
if (app.documents.length > 0) {
    ////// collect layers //////
    var theChannels = collectSpotChannels ();
    alert ("spot channels\n"+theChannels.join("\n"));
    };
////////////////////////////////////
////// collect layers //////
function collectSpotChannels () {
    var myDocument = activeDocument;
// get number of layers;
    var ref = new ActionReference();
    ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
    var applicationDesc = executeActionGet(ref);
    var theNumber = applicationDesc.getInteger(stringIDToTypeID("numberOfChannels"));
// pixel dimensions;
    var theWidth = applicationDesc.getUnitDoubleValue(stringIDToTypeID("width"));
    var theHeight = applicationDesc.getUnitDoubleValue(stringIDToTypeID("height"));
    var theRes = applicationDesc.getUnitDoubleValue(stringIDToTypeID("resolution"));
    var thePixels = (theWidth*theRes/72)*(theHeight*theRes/72);
// process the channels;
    var theChannels = new Array;
    for (var m = 0; m <= theNumber; m++) {
    try {
    var ref = new ActionReference();
    ref.putIndex(stringIDToTypeID( "channel" ), m);
    var channelDesc = executeActionGet(ref);
// collect values;
    var theName = channelDesc.getString(stringIDToTypeID('channelName'));
    var theIndex = channelDesc.getInteger(stringIDToTypeID('itemIndex'));

    var theColor = channelOpt.getObjectValue(stringIDToTypeID("color"));
    var colorIndicates = channelOpt.getEnumerationValue(stringIDToTypeID("colorIndicates"));
    var theHistogram = channelDesc.getList(stringIDToTypeID('histogram'));
    var value0 = theHistogram.getInteger(0);
// if not completely black and not alpha channel;
    if (value0 != thePixels && colorIndicates == 1399877492) {
// if hsb-color;
        if (typeIDToStringID(channelOpt.getObjectType(channelOpt.getKey(1))) == "HSBColorClass") {

Yes! here is a sample file, the MTV 2 has already the channels turned into layers, but the layers are black, I was wodering if i possible to grab the values/colors of the channels and paste it in the layers. Thanks for the support

[c.pfaffenbichler]

The last Script I posted canbe used to determine Spot Channels’ colors, feel free to combine the Scripts as necessary.

thank you so much @c.pfaffenbichler
