Assuming that the layer name is "Layer 0", how I flip it horizontally or vertically?, keeping the anchor point in center

You can accomplish everything with ScriptingListener

this and for horizontal

This might be easier.


flipLayer('v');  
//flipLayer('h');  
   
function flipLayer(direction) {  
switch (direction.toLowerCase()){  
    case 'h' : direction = 'Hrzn'; break;  
    case 'v' : direction = 'Vrtc'; break;  
    default : return;  
    }  
    var desc23 = new ActionDescriptor();  
    desc23.putEnumerated( charIDToTypeID('Axis'), charIDToTypeID('Ornt'), charIDToTypeID(direction) );  
 try{  
    executeAction( charIDToTypeID('Flip'), desc23, DialogModes.NO );  
 }catch(e){}  
};

I tried that, but it doesn't let me target a specific layer by name. It be default flips the bottom layer, any workaround?

It works on the active layer, you must select the layer first.
