New document from layer

Hello, not sure if it's correct group but maybe someone know how exactly Photoshop 4-chars commands work.

I'm trying to find correct script to create new document from specific layer by id. But it always uses active layer. Is there any way to change the script to fit my requirements?

var mkId = charIDToTypeID("Mk "),
       action = new ActionDescriptor(),
       nullId = charIDToTypeID("null"),
       actionRef = new ActionReference(),
       docId = charIDToTypeID("Dcmn");
    actionRef.putClass(docId),
    action.putReference(nullId, actionRef);

    var nmId = charIDToTypeID("Nm ");
    action.putString(nmId, "My new document");

    var usingId = charIDToTypeID("Usng"),
    // trying to set target layer, but it doesn't work
    c = new ActionReference();
    c.putIndex( charIDToTypeID( "Lyr " ), 2);

    action.putReference(usingId, c);
    var versionId = charIDToTypeID("Vrsn");
    action.putInteger(versionId, 5),
    executeAction(mkId, action, DialogModes.NO);

I do not understand what you mean by expanding the layer tree. Is that the Layers palette? If you do not want to activate the reference layer. You could get the documents layers to get all the layers and then find the reference layer. Open a new document the with the same size and resolution as the current document. Add a new artlayer. Set the new layer to be the same as reference layer. Then delete the new document's bottom layer. Could be done using DOM code action manager code would not be needed.

Sorry, could you please provide some details how can I create new layer and make it the same as reference layer (or layers section). I wrote small script but it doesn't work:

function main() {

var doc = app.activeDocument;

var lr = doc.activeLayer; // replace it with getTargetLayer(doc, id);

var newDoc = app.documents.add(doc.width, doc.height);

var newLr = newDoc.artLayers.add();

newDoc.activeLayer = lr; // this code causes exception

}

Sorry I only hack at Photoshop scripting and do not know javascript.. It seemed logical that you would be able to open a new document the correct size and resolution. Add a new layer and set it with an artlayer from the original document. However it look like Adobe does not allow that. I get a error or the new layer added does not get set with an assignment statement using the atrlayer object from the original and remains empty.

function main() {

var doc = app.activeDocument;

var lr = doc.activeLayer; // replace it with getTargetLayer(doc, id);

var newDoc = app.documents.add(doc.width, doc.height, doc.resolution);

var newLr = newDoc.artLayers.add();

// newDoc.activeLayer = lr;

// newLr = lr; // nothing get set no error message

newLr.kind = LayerKind.TEXT;

textColor = new SolidColor;

textColor.rgb.red = 255;

textColor.rgb.green = 0;

textColor.rgb.blue = 0;

newLr.textItem.color = textColor;

newLr.textItem.font = "ArialMT";

newLr.blendMode = BlendMode.NORMAL;

newLr.textItem.fauxBold = false;

newLr.textItem.fauxItalic = false;

newLr.textItem.underline = UnderlineType.UNDERLINEOFF;

newLr.textItem.capitalization = TextCase.NORMAL;

newLr.textItem.antiAliasMethod = AntiAlias.SHARP;

newLr.textItem.size = 20;

newLr.textItem.position = Array(40, 40 );

newLr.textItem.contents = "text";

newLr = lr; // nothing get set no error message

}

main();

Duplicate layer duplicate the Active layer set the layer you want to create a new document with as the Active layer before using the code.

function NewDocFromActiveLayer(LayerName,DocName) {

var idMk = charIDToTypeID( "Mk " );

var desc54 = new ActionDescriptor();

var idnull = charIDToTypeID( "null" );

var ref9 = new ActionReference();

var idDcmn = charIDToTypeID( "Dcmn" );

ref9.putClass( idDcmn );

desc54.putReference( idnull, ref9 );

var idNm = charIDToTypeID( "Nm " );

desc54.putString( idNm, DocName );

var idUsng = charIDToTypeID( "Usng" );

var ref10 = new ActionReference();

var idLyr = charIDToTypeID( "Lyr " );

var idOrdn = charIDToTypeID( "Ordn" );

var idTrgt = charIDToTypeID( "Trgt" );

ref10.putEnumerated( idLyr, idOrdn, idTrgt );

desc54.putReference( idUsng, ref10 );

var idLyrN = charIDToTypeID( "LyrN" );

desc54.putString( idLyrN, LayerName );

var idVrsn = charIDToTypeID( "Vrsn" );

desc54.putInteger( idVrsn, 5 );

executeAction( idMk, desc54, DialogModes.NO );

}

NewDocFromActiveLayer("llll","xxx");

Thanks for reply! Really the point is to NOT use active layer but use layer reference instead.

Create new doc using active layer is exactly how the code I shared works

I do not understand what is a layer reference. If it is a layer in the document save the active layers in a variable set the docment's active layer the layer reference duplicate the active layer into a new document then restore the document active layer to the one you saved before. If you want to us a layer you normally need to target the layer first. Many Photoshop tools and commands work on or with the active layer. If you look at the duplicate layer dialog the source layer can not be set it is the current targeted active layer. You have to target the correct document not the new document you opened that became the Acrive document set a varable Doc to the original source document first. Set Doc.acticeLayer = the old saved active layer.
