Hey

 

Running this :

var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID("AdjL"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
var desc = executeActionGet(ref);
var data = desc.getList(stringIDToTypeID("adjustment")).getObjectValue(0).getData(stringIDToTypeID("legacyContentData"));

var Brightness= getShortIntFromData(data, 0),
var Contrast= getShortIntFromData(data, 2),
var UseLegacy= (getShortIntFromData(data, 4)) ? 1 : 0


If the bri&contrast is set to Use Legacy = I get all data

But if its "new" then I can't get any data no matter what I do.

Any idea, any1 ?

 

Regards
Dariusz

    Try thia

     

    function get_contrast_desc(id)
    {
    try {
        var r = new ActionReference();
        var d = new ActionDescriptor();

        r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("json"));
        r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
        d.putReference(stringIDToTypeID("null"), r);

        d.putInteger(stringIDToTypeID("layerID"), id);
        d.putBoolean(stringIDToTypeID("layerInfo"), true);

        d.putBoolean(stringIDToTypeID( "includeAncestors" ), false);

        eval("var json="+executeAction(stringIDToTypeID("get"), d, DialogModes.NO).getString(stringIDToTypeID("json")));

        var d = new ActionDescriptor();

        if (!json.layers) return d;
        if (json.layers.length != 1) return d;
        if (json.layers[0].id != id) return d;

        var adj = json.layers[0].adjustment;

        if (!adj) return d;

        if (adj.brightness != undefined) d.putInteger(stringIDToTypeID("brightness"), adj.brightness);
        if (adj.center     != undefined) d.putInteger(stringIDToTypeID("center"),     adj.center);
        if (adj.useLegacy  != undefined) d.putBoolean(stringIDToTypeID("useLegacy"),  adj.useLegacy);

        return d;
        }
    catch (e) { throw(e); }
    }

      This is very interesting! I am using a script that I wrote myself few years ago which is reading the values from a levels layer using getData(stringIDToTypeID("legacyContentData")) which is not working anymore in PS 24.6 . I played with your function and json.layers[0].adjustment.brightness it really reads the value! But what are the new names for channel values for Levels adjustments layer? In my old scripts I was parsing something like Dariusz using getShortIntFromData

       

      Best regards,

      Alain
