[Script] Adjust Hue/Saturation

[francisco_axlot]

I've got an image that has its color changed by a clipped mask above it. I am trying to build a script to automate this task, setting different values for the hue, saturation and lightness.

I've managed to create the following script, which creates a Hue/Saturation layer with "Colorize" checkbox enabled, however, I don't know how to initialize the hue, saturation and lightness values.

/////////////

var idMk = charIDToTypeID( "Mk  " );

    var desc43 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

        var ref8 = new ActionReference();

        var idAdjL = charIDToTypeID( "AdjL" );

        ref8.putClass( idAdjL );

    desc43.putReference( idnull, ref8 );

    var idUsng = charIDToTypeID( "Usng" );

        var desc44 = new ActionDescriptor();

        var idType = charIDToTypeID( "Type" );

            var desc45 = new ActionDescriptor();

            var idpresetKind = stringIDToTypeID( "presetKind" );

            var idpresetKindType = stringIDToTypeID( "presetKindType" );

            var idpresetKindDefault = stringIDToTypeID( "presetKindDefault" );

            desc45.putEnumerated( idpresetKind, idpresetKindType, idpresetKindDefault );

           var idClrz = charIDToTypeID( "Clrz" );

            desc45.putBoolean( idClrz, true );

        var idHStr = charIDToTypeID( "HStr" );

        desc44.putObject( idType, idHStr, desc45 );

    var idAdjL = charIDToTypeID( "AdjL" );

    desc43.putObject( idUsng, idAdjL, desc44 );

executeAction( idMk, desc43, DialogModes.NO );

/////////////

Does anyone know how can I set those values? Thanks in advance.

I do not know if I understand correctly

This is very usefl. Sorry to post on an old post but I can' find the answer anywhere else.

What if I don't want to create the adjustmnent layer, but only edit its parameters?

Because I have it within a for loop and I don't need it to be re-created ecery time.

Try this (without colorize):

adjustHSL(-180, 50, 0);

function adjustHSL(hue, saturation, lightness) {
    try {
        activeDocument.activeLayer.kind == LayerKind.HUESATURATION;
        var s2t = function (s) {
            return app.stringIDToTypeID(s);
        };
        var descriptor = new ActionDescriptor();
        var descriptor2 = new ActionDescriptor();
        var descriptor3 = new ActionDescriptor();
        var list = new ActionList();
        var reference = new ActionReference();
        reference.putEnumerated(s2t("adjustmentLayer"), s2t("ordinal"), s2t("targetEnum"));
        descriptor.putReference(s2t("null"), reference);
        descriptor3.putInteger(s2t("hue"), hue);
        descriptor3.putInteger(s2t("saturation"), saturation);
        descriptor3.putInteger(s2t("lightness"), lightness);
        list.putObject(s2t("hueSatAdjustmentV2"), descriptor3);
        descriptor2.putList(s2t("adjustment"), list);
        descriptor.putObject(s2t("to"), s2t("hueSaturation"), descriptor2);
        executeAction(s2t("set"), descriptor, DialogModes.NO);
    } catch (e) {
        //alert("The active layer isn't a Hue/Saturation adjustment layer!");
    }
}

With colorize:

adjustHSLcolorize(true, 360, 50, 0);

function adjustHSLcolorize(colorize, hue, saturation, lightness) {
    try {
        activeDocument.activeLayer.kind == LayerKind.HUESATURATION;
        var s2t = function (s) {
            return app.stringIDToTypeID(s);
        };
        var descriptor = new ActionDescriptor();
        var descriptor2 = new ActionDescriptor();
        var descriptor3 = new ActionDescriptor();
        var list = new ActionList();
        var reference = new ActionReference();
        reference.putEnumerated(s2t("adjustmentLayer"), s2t("ordinal"), s2t("targetEnum"));
        descriptor.putReference(s2t("null"), reference);
        descriptor2.putBoolean(s2t("colorize"), colorize);
        descriptor3.putEnumerated(s2t("channel"), s2t("channel"), s2t("composite"));
        descriptor3.putInteger(s2t("hue"), hue);
        descriptor3.putInteger(s2t("saturation"), saturation);
        descriptor3.putInteger(s2t("lightness"), lightness);
        list.putObject(s2t("hueSatAdjustmentV2"), descriptor3);
        descriptor2.putList(s2t("adjustment"), list);
        descriptor.putObject(s2t("to"), s2t("hueSaturation"), descriptor2);
        executeAction(s2t("set"), descriptor, DialogModes.NO);
    } catch (e) {
        //alert("The active layer isn't a Hue/Saturation adjustment layer!");
    }
}

@RamonMazinga – how did the code that I posted work for you?

[ChaosEtc]

I don't know about Ramon, but it worked great for me.

@ChaosEtc 

Thanks for the feedback! 👍

how does one learn logic behind this?

Behind what in particular – AM code?
