How to flatten a single layer in photosop using a script (js reference)?

[marqueth1054]

I've see  lot of script using  activeDocument.flatten() but i need to know hot to flatten a single layer

activeDocument.layers[3] for example.

thanks in advance

i'm usign ps cc2014 by the way

Are you talking about rasterizing a layer? You need at least two layers to flatten. Use scriptlistener to record what you want to script.

yes, i just realize that thanks

there is a command to rasterize a single layer ?

Hi,

you can rasterize a single layer (e.g. a Solid Color layer, etc) with the following one, which takes the layer name (string) as a parameter:

function rasterizeLayerByName (layerName) {
  var s = function(str) { return app.stringIDToTypeID(str) }
  var d = new ActionDescriptor();
  var r = new ActionReference();
  r.putName(s('layer'), layerName);
  d.putReference(s('target'), r);
  executeAction(s('rasterizeLayer'), d, DialogModes.NO);
}
// Example:
// rasterizeLayerByName('Gradient Fill 1');

Hope this helps,

Btw, Davide how does that work with layer name as param? It's not a unique id across whole doc or even group.

A rather simple alternative is to create an empty layer below and use artLayer.merge(). There is also artLayer.rasterize(RasterizeType), but I think it had the issue that even with param RasterizeType.ENTIRELAYER it does not rasterize layer style & smart filter. This limitation might (or might not) apply to Davide's solution also since it uses similar attribute.

Hi Matias,

you're correct - layer names aren't unique. Here's a version using layer ID:

function rasterizeLayerByID (id) {  
  var s = function(str) { return app.stringIDToTypeID(str) }  
  var d = new ActionDescriptor();  
  var r = new ActionReference();  
  r.putIdentifier(s('layer'), id);  
  d.putReference(s('target'), r);  
  executeAction(s('rasterizeLayer'), d, DialogModes.NO);  
}  

Both (id and name functions) should work with Smart Objects and the like.

Best,

Davide
