Combine two channels to generate a new channel

[marlon248285867nip]

Hi everyone, I don't have a solid grasp with JavaScript, but I wanna ask if is possible reproduce the applyimage function using a script as in the attached picture.

I'm looking the way to generate a new channel (green for example) from a splited channels (cyan and yellow).

is it possible?

My goal is to add two spot channels (red ,green) to cmyk image, and generate six color separations for screen printing.  I appreciate your help.

There is no "standard" object model code. So use scripting listener to record action manager code, you may need to swap out the document name with a variable for the current doc if using this on different files.

Here is an example from a different script using different values, with the raw SL code passed through the Clean SL script:

Edit: Another example of a scripted Apply Image is in the link below:

@marlon248285867nip  – Here is the raw SL recorded JS code:

var idapplyImageEvent = stringIDToTypeID( "applyImageEvent" );
    var desc361 = new ActionDescriptor();
    var idwith = stringIDToTypeID( "with" );
        var desc362 = new ActionDescriptor();
        var idto = stringIDToTypeID( "to" );
            var ref48 = new ActionReference();
            var idchannel = stringIDToTypeID( "channel" );
            var idordinal = stringIDToTypeID( "ordinal" );
            var idtargetEnum = stringIDToTypeID( "targetEnum" );
            ref48.putEnumerated( idchannel, idordinal, idtargetEnum );
            var idlayer = stringIDToTypeID( "layer" );
            var idbackground = stringIDToTypeID( "background" );
            ref48.putProperty( idlayer, idbackground );
            var iddocument = stringIDToTypeID( "document" );
            ref48.putName( iddocument, "18.jpg_Yellow" );
        desc362.putReference( idto, ref48 );
        var idinvert = stringIDToTypeID( "invert" );
        desc362.putBoolean( idinvert, true );
        var idcalculation = stringIDToTypeID( "calculation" );
        var idcalculationType = stringIDToTypeID( "calculationType" );
        var idlinearDodge = stringIDToTypeID( "linearDodge" );
        desc362.putEnumerated( idcalculation, idcalculationType, idlinearDodge );
        var idpreserveTransparency = stringIDToTypeID( "preserveTransparency" );
        desc362.putBoolean( idpreserveTransparency, true );
        var iduseMask = stringIDToTypeID( "useMask" );
            var ref49 = new ActionReference();
            var idchannel = stringIDToTypeID( "channel" );
            var idordinal = stringIDToTypeID( "ordinal" );
            var idtargetEnum = stringIDToTypeID( "targetEnum" );
            ref49.putEnumerated( idchannel, idordinal, idtargetEnum );
            var idlayer = stringIDToTypeID( "layer" );
            var idbackground = stringIDToTypeID( "background" );
            ref49.putProperty( idlayer, idbackground );
            var iddocument = stringIDToTypeID( "document" );
            ref49.putName( iddocument, "18.jpg_Yellow" );
        desc362.putReference( iduseMask, ref49 );
        var idinvertMask = stringIDToTypeID( "invertMask" );
        desc362.putBoolean( idinvertMask, true );
    var idcalculation = stringIDToTypeID( "calculation" );
    desc361.putObject( idwith, idcalculation, desc362 );
executeAction( idapplyImageEvent, desc361, DialogModes.NO );

Here it is in a function using the Clean SL script:

applyImageEvent(true, true, true);

function applyImageEvent(invert, preserveTransparency, invertMask) {
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};

	var descriptor = new ActionDescriptor();
	var descriptor2 = new ActionDescriptor();
	var reference = new ActionReference();
	var reference2 = new ActionReference();

	reference.putEnumerated( s2t( "channel" ), s2t( "ordinal" ), s2t( "targetEnum" ));
	reference.putProperty( s2t( "layer" ), s2t( "background" ));
	reference.putName( s2t( "document" ), "18.jpg_Yellow" );
	descriptor2.putReference( s2t( "to" ), reference );
	descriptor2.putBoolean( s2t( "invert" ), invert );
	descriptor2.putEnumerated( s2t( "calculation" ), s2t( "calculationType" ), s2t( "linearDodge" ));
	descriptor2.putBoolean( s2t( "preserveTransparency" ), preserveTransparency );
	reference2.putEnumerated( s2t( "channel" ), s2t( "ordinal" ), s2t( "targetEnum" ));
	reference2.putProperty( s2t( "layer" ), s2t( "background" ));
	reference2.putName( s2t( "document" ), "18.jpg_Yellow" );
	descriptor2.putReference( s2t( "useMask" ), reference2 );
	descriptor2.putBoolean( s2t( "invertMask" ), invertMask );
	descriptor.putObject( s2t( "with" ), s2t( "calculation" ), descriptor2 );
	executeAction( s2t( "applyImageEvent" ), descriptor, DialogModes.NO );
}

P.S. You might be able to do this via an action, I haven't tried so it may not be that easy.
