script for mask to layer or group

  • June 29, 2023

Greetings to all
I want a script that creates a layer mask
In the event that the layer already has a mask, it will go to the mask

 

I mean, a script that checks the layer if it does not have a mask, it makes a mask for it, and if there is a mask, it goes directly to it

 

- Note if possible
I want it to be done on the layers and also the group

 

Thank you for your interest and good work..

    Well, that does not appear to be what you asked earlier when conditionals were mentioned.

     

    The following function will add a reveal all layer mask to an active layer (with no error checks or conditions).

     

    addMask("RvlA"); // or "HdAl"

function addMask(revealOrHide) {
    var idMk = charIDToTypeID("Mk  ");
    var desc2 = new ActionDescriptor();
    var idNw = charIDToTypeID("Nw  ");
    var idChnl = charIDToTypeID("Chnl");
    desc2.putClass(idNw, idChnl);
    var idAt = charIDToTypeID("At  ");
    var ref1 = new ActionReference();
    var idChnl = charIDToTypeID("Chnl");
    var idChnl = charIDToTypeID("Chnl");
    var idMsk = charIDToTypeID("Msk ");
    ref1.putEnumerated(idChnl, idChnl, idMsk);
    desc2.putReference(idAt, ref1);
    var idUsng = charIDToTypeID("Usng");
    var idUsrM = charIDToTypeID("UsrM");
    var idHideOrReveal = charIDToTypeID(revealOrHide); 
    desc2.putEnumerated(idUsng, idUsrM, idHideOrReveal);
    executeAction(idMk, desc2, DialogModes.NO);
}

     

    or

     

    addMask("revealAll"); // or "hideAll"

function addMask(revealOrHide) {
	function c2t(s) {
        return app.charIDToTypeID(s);
    }
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};
	var descriptor = new ActionDescriptor();
	var reference = new ActionReference();
	descriptor.putClass(s2t("new"), s2t("channel"));
	reference.putEnumerated(s2t("channel"), s2t("channel"), s2t("mask"));
	descriptor.putReference(s2t("at"), reference);
	descriptor.putEnumerated(s2t("using"), c2t("UsrM"), s2t(revealOrHide)); 
	executeAction(s2t("make"), descriptor, DialogModes.NO);
}

    To select the mask channel (or composite channel):

     

    selectLayerCompositeChannel("mask");

function selectLayerCompositeChannel(chanPara) {
    // "RGB" | "mask"
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};
	var descriptor = new ActionDescriptor();
	var reference = new ActionReference();
	reference.putEnumerated( s2t( "channel" ), s2t( "channel" ), s2t( chanPara ));
	descriptor.putReference( s2t( "null" ), reference );
	descriptor.putBoolean( s2t( "makeVisible" ), false );
	executeAction(s2t( "select" ), descriptor, DialogModes.NO);
}

     

    To toggle between the composite and mask channels:

https://community.adobe.com/t5/photoshop-ecosystem-discussions/detect-if-mask-or-layer-is-selected-with-js-script/m-p/11153109
*/

s2t = stringIDToTypeID;

(r = new ActionReference()).putProperty(s2t('property'), p = s2t('hasUserMask'));
r.putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
if (executeActionGet(r).getBoolean(p)) {
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('name'));
    (r = new ActionReference()).putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
    layerName = executeActionGet(r).getString(p);

    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('channelName'));
    r.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
    channelName = executeActionGet(r).getString(p);

    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('alphaChannelOptions'));
    r.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
    alphaChannel = executeActionGet(r).hasKey(p)

    if (channelName.indexOf(layerName) == 0 && !alphaChannel) {
        // var select = confirm('Layer mask selected\nSelect layer?') ? 'RGB' : null
        var select = 'RGB';
    } else {
        // var select = confirm('Layer selecter\nSelect mask?') ? 'mask' : null
        var select = 'mask';
    }
    if (select) {
        (r = new ActionReference()).putEnumerated(s2t("channel"), s2t("channel"), s2t(select));
        (d = new ActionDescriptor).putReference(s2t("null"), r);
        executeAction(s2t("select"), d, DialogModes.NO);
    }
}

      THEN WHY DON'T YOU ANSWER THE QUESTIONS SO THAT I CAN HELP YOU?!

       

      What is the source of the mask?

       

      Is there a selection?

       

      If no selection, is it just a simple reveal all or hide all mask?

       

      And if there is an existing mask, do you want to select/target the mask channel?

      To check if a mask is active:

s2t = stringIDToTypeID;
(r = new ActionReference()).putProperty(s2t('property'), p = s2t('userMaskEnabled'));
r.putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
if (executeActionGet(r).hasKey(p)) alert (executeActionGet(r).getBoolean(p));

      @Stephen Marsh 

      Thank you, sir, for your interest and help

      But I tried the code, it only checks the layer and does not do any other action


      I want, in the absence of a mask, to create a mask for the specified layer or group

      And if there is a mask, it will go to the mask directly

      That is correct, I only provided related resources, not full working code.

       

      I have updated my original post asking further questions as it is not crystal clear what you are requesting.

      @Mohamed Hameed21513110 

       

      I am presuming a raster mask, not vector.

       

      Do you mean that an existing mask would be added to, or that an existing mask would be replaced?

       

      What is the source of the mask?

       

      Is there a selection?

       

      If no selection, is it just a simple reveal all or hide all mask?

       

      Some resources for you to check if a layer has a mask:

alert(hasLayerMask());
