Save layers of Acorn image as separate files

var path = "/Users/jsb/Desktop/LayerTest";
var filename = "jefftest.acorn";

var acorn = JSTalk.application("Acorn");
var doc = acorn.open(path + "/" + filename);

var count = doc.layers().count();

for (i = 0; i < count; i++)
{
    doc.layers()[i].visible = NO;
}

for (i = 0; i < count; i++)
{
    if (i > 0)
        doc.layers()[i-1].visible = NO;
        
    doc.layers()[i].visible = YES;
    
    doc.dataOfType("public.png").writeToFile(path + "/layer" + i + ".png");
}

doc.close();

Is there any reason to duplicate the document for each layer? seems the tmpDoc.duplicate() and tmpDoc.close could go outside the outer loop. I don't have time to try this at the moment but wondered... you set them visible/invisible each time through the loop... ?

I have a similar script that uses the names of the layers as the names of the output files which is handy for some cases.

No, that was just sloppy code. You don't actually have to duplicate the document at all. Here's an updated version that's a little cleaner.

ok!. wondered about that. thanks for the clarification.
