[Q] Is there way to check if the LayerSet is ArtBoard without selecting?

Hi all,

 

Is there way to check if the LayerSet is ArtBoard without selecting?

I mean not make active the LayerSet.

 

My understanding following code returns true if selected LayerSet is Artboard.

Is this only way to get info?

var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
var isArtboardLayer = executeActionGet(ref).getBoolean(stringIDToTypeID("artboardEnabled"));

$.writeln(isArtboardLayer);

 

When I try to get the info in following code, above code does not work

traverseLayer(app.activeDocument.layerSets, 0);

function traverseLayer(layers, level) {
	try{
		for(var i = 0; i < layers.length; i++) {
			var l = layers[i];
			$.writeln(level + ": (" + l.typename + ")", l.name);
			if (l.typename == 'LayerSet') {
			 
				// TODO: Check if it is ArtBoard
			 
				traverseLayer(l.layers, level+1); // recursive
			}
		}
	}catch(e){
		$.writeln("EXCEPTION: ", e);
	}
}

 

I saw some code is selectForwardLayer(). Retrieve Artboard reference of active nested layer

But I don't want to change selected layer by some reasons.

 

Is there any way to check if it is ArtBoard LayerSet without selecting?

 

Thank you,

Naoki

Instead of using the activeLayer/s you can identify Layers by their indices or identifiers.

c.pfaffenbichler​ Thank you very much for the code.

Line #22 need to be modified to avoid error, but it works great.

Line #21

    for (var m = 1; m <= theNumber; m++) { // to be 1 based

//    for (var m = 0; m < theNumber+1; m++) {

If you use background layer you may use c.pfaffenbichler for loop in your code, but if you don't, you still can use his for loop, but then in first instance you mast check if background layer exists to take into account its variable in later part of script. btw. thanks to your code I found $.writeln() content does not have to be used with pluses, but may be with comas 😉

Do you know what this $.writeln actually is? I see it more often, most times when righting to log files orso. Feels like PHP code orso.

I tried the script with/out the change and it works same. Could you share example of .psd (with artboards) the error occurs on when using c.pfaffenbichler code, but not with yours?

You do know many if not most scripts are broken here, i think you do know. But we need to hunt for the locations where need to add [i] back in. The updating of this forum mangled all the scripts up to that point.

I asked a question after I edited posts with crippled codes. Later I found out that Naoki-Hada post about error was not to earlier script but to the script he did not post yet in that time 😉

is this a riddle, why not add description what your linking.

I add here a translated version of @songgebs46585277  addition. Though the method used can be done better. saving a file then reopening it and then cropping makes the script slow. Better is making a duplicate of the current document, then crop to the active artboard and export this. This is faster.

 

An example of this is export layer comps file which comps with photoshop. I use this same approach in a script i got for export layer comps and artboards in a script of mine. Normally its either one or the other, you cant export layer comps from a file which has artboards. 

 

You function will not do anything since the last function is never called??

// Since the current (April 19, 2018) official api does not support the drawing board attribute query,

    try {
        if (app.activeDocument.backgroundLayer) {

    }

    var ref = new ActionReference();
    ref.putIndex(stringIDToTypeID("layer"), itemIndex);
    var desp = executeActionGet(ref);
    try {
        return desp.getBoolean(stringIDToTypeID("artboardEnabled"));
    } catch (e) {
        return false;
    }
}

// Get the size of the artboard and the coordinates of the origin from the upper left corner of the entire canvas
function getArtboardBounds (artboardLayer) {
    var originalRuler = app.preferences.rulerUnits;
    
    app.preferences.rulerUnits = Units.PIXELS;
    var itemIndex = artboardLayer.itemIndex;

    app.preferences.rulerUnits = originalRuler;
    return [UnitValue(theX, "px"), UnitValue(theY, "px"), UnitValue(theX2, "px"), UnitValue(theY2, "px")];
}

// Export an artboard separately, similar to the function of "File -> Export -> Artboard to File" in ps

    // Create a new document and copy the artboard layer group to guoqu 
    var currentDoc = app.activeDocument;
    var newDoc = app.documents.add (currentDoc.width, currentDoc.height, currentDoc.resolution, null, NewDocumentMode.RGB, DocumentFill.TRANSPARENT);
    app.activeDocument = currentDoc;
    var newArtboard = artboard.duplicate (newDoc);
    app.activeDocument = newDoc;
