Script: Delete selected layer, if empty.

There are various ways to delete all layers that are empty, but is there a script which can detect if the "selected" layer is empty, and if so, delete it?
Thanks!

Correct answer r-bin

I'm using CS6.. lol

 

Thanks!


Option for CS6

var r = new ActionReference();    
r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("targetLayers"));
r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));

var list = executeActionGet(r).getList(stringIDToTypeID("targetLayers"));

var selected = new Array();
var ids = new Array();

for (var i = 0; i < list.count; i++) selected.push(list.getReference(i).getIndex());

for (var i = 0; i < selected.length; i++) 
    {
    var r = new ActionReference();    
    r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("bounds"));
    r.putIndex(stringIDToTypeID("layer"), selected[i]);

    var bounds = executeActionGet(r).getObjectValue(stringIDToTypeID("bounds"));

    var x0 = bounds.getUnitDoubleValue(stringIDToTypeID("left"));
    var x1 = bounds.getUnitDoubleValue(stringIDToTypeID("right"));
    var y0 = bounds.getUnitDoubleValue(stringIDToTypeID("top"));
    var y1 = bounds.getUnitDoubleValue(stringIDToTypeID("bottom"));

    if (!x0 && !x1 && !y0 && !y1) ids.push(selected[i]);
    }

if (ids.length)
    {
    var r = new ActionReference();
    for (var i = 0; i < ids.length; i++) r.putIndex(stringIDToTypeID("layer"), ids[i]);

    var d = new ActionDescriptor();
    d.putReference(stringIDToTypeID("null"), r);
    executeAction(stringIDToTypeID("delete"), d, DialogModes.NO); 
    }

This script removes empty layers among selected.
 
var r = new ActionReference();    
r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("targetLayersIDs"));
r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));

var list = executeActionGet(r).getList(stringIDToTypeID("targetLayersIDs"));

var selected = new Array();
var ids = new Array();

for (var i = 0; i < list.count; i++) selected.push(list.getReference(i).getIdentifier());

for (var i = 0; i < selected.length; i++) 
    {
    var r = new ActionReference();    
    r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("bounds"));
    r.putIdentifier(stringIDToTypeID("layer"), selected[i]);

    var bounds = executeActionGet(r).getObjectValue(stringIDToTypeID("bounds"));

    var x0 = bounds.getUnitDoubleValue(stringIDToTypeID("left"));
    var x1 = bounds.getUnitDoubleValue(stringIDToTypeID("right"));
    var y0 = bounds.getUnitDoubleValue(stringIDToTypeID("top"));
    var y1 = bounds.getUnitDoubleValue(stringIDToTypeID("bottom"));

    if (!x0 && !x1 && !y0 && !y1) ids.push(selected[i]);
    }

if (ids.length)
    {
    var r = new ActionReference();
    for (var i = 0; i < ids.length; i++) r.putIdentifier(stringIDToTypeID("layer"), ids[i]);

    var d = new ActionDescriptor();
    d.putReference(stringIDToTypeID("null"), r);
    executeAction(stringIDToTypeID("delete"), d, DialogModes.NO); 
    }

    Which version of photoshop?
    My script does not work in low-end Photoshop like CS6.
    But it is possible to remake.

    Doesn't the "Delete All Empty layers" script shipped with PS work for you.

    Thanks Manan,

     

    I have several layers that are empty, which i need to keep.

    This action is part of a larger script.

    For this part, it focuses on a selected layer, and remove it, if empty.

     

    Thanks

    Jeff

    Wouldn’t 

    ( 0 == layer.bounds[2] && (0 == layer.bounds[3])

    theoretically also identify Layers that are off-canvas and the lower right corner of whic is exactly in the top left corner of the canvas? 


    Hahaha, nuts, almost got a right solution there... 🙂

    I left the activeLayer part out on purpose to encourage OP to get acquainted with the Photoshop Scripting Reference.

     

    For OP: the following link takes you to Photoshop Scripting documentation.

    Application

     

    Alternatively, the following link presents the same information in a slightly different way. Somehow, when I'm stuck using the first link, my brain "gets it" using this one: (I suppose it doesn't make any sense, but it works for me)

    Application

     

    If you're ever stuck on something, it often pays off to go to either one and look around.

     

    Another link I can highly recommend is this one which deals less with Photoshop and more with "how to code/script"

    https://estk.aenhancers.com/

     

    Good luck almost namesake!
