Hello everyone,

is there a way to delete the last smart filter from a smart object via script?

With thanks to @c.pfaffenbichler for the code to get the smart filter count.

if (app.documents.length > 0) {
    var doc = app.activeDocument;
    if (doc.activeLayer.kind == LayerKind.SMARTOBJECT) {
        // Get the number of filters applied to the currently selected layer, by c.pfaffenbichler
        var ref = new ActionReference();
        ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
        var layerDesc = executeActionGet(ref);
        var soDesc = layerDesc.getObjectValue(stringIDToTypeID('smartObject'));
        var soMoreDesc = layerDesc.getObjectValue(stringIDToTypeID('smartObjectMore'));
        var filterFXcount = soDesc.getList(stringIDToTypeID('filterFX')).count
        // Delete the last filter
        var iddelete = stringIDToTypeID("delete");
        var desc30193 = new ActionDescriptor();
        var idnull = stringIDToTypeID("null");
        var ref10120 = new ActionReference();
        var idfilterFX = stringIDToTypeID("filterFX");
        ref10120.putIndex(idfilterFX, filterFXcount); // The last filter
        var idlayer = stringIDToTypeID("layer");
        var idordinal = stringIDToTypeID("ordinal");
        var idtargetEnum = stringIDToTypeID("targetEnum");
        ref10120.putEnumerated(idlayer, idordinal, idtargetEnum);
        desc30193.putReference(idnull, ref10120);
        executeAction(iddelete, desc30193, DialogModes.NO);
    } else {
        alert("Please select a smart object layer.");
    }
} else {
    alert("Please open a document first.");
}

Hi @Innotex Nico Tanne

You can use the following script in Photoshop:

var doc = app.activeDocument;

var smartObject = doc.activeLayer;

smartObject.activeLayer.appliedSmartFilters[0].remove();

Ensure the smart object has a smart filter before running.

Thankyou!

Thanks for your quick reply, but unfortunately smartObject.appliedSmartFilters seems to be no longer available and is undefined 😞

Here is the raw action manager recording to delete a specific index number filter, unlike many scripting index number which start at zero, this starts at 1, which makes it easy to delete a specific smart filter (in this example, the 2nd filter)..

That's the easy bit. The challenge is working out the length of the idfilterFX index.

var iddelete = stringIDToTypeID( "delete" );
    var desc30193 = new ActionDescriptor();
    var idnull = stringIDToTypeID( "null" );
        var ref10120 = new ActionReference();
        var idfilterFX = stringIDToTypeID( "filterFX" );
        ref10120.putIndex( idfilterFX, 2 ); // Index # starting at 1
        var idlayer = stringIDToTypeID( "layer" );
        var idordinal = stringIDToTypeID( "ordinal" );
        var idtargetEnum = stringIDToTypeID( "targetEnum" );
        ref10120.putEnumerated( idlayer, idordinal, idtargetEnum );
    desc30193.putReference( idnull, ref10120 );
executeAction( iddelete, desc30193, DialogModes.NO );
